2020 seems to be the year of plant-based eruptions.
In January, more than 300,000 people supported the UK's "Vegetarian 2020" campaign. Many fast food restaurants and supermarkets in the UK have expanded their offerings into a popular plant-based movement. Innova Market Insights also listed "plant-based revolution" as the second trend in 2020; At the same time, Nelson's report shows that on top of last year's sales of plant-based foods of more than US$3.3billion, which is expected to exceed US$5billion by 2020.
The plant base is mainly supported by various plant proteins. What is the situation of vegetable protein market across the world? What are the driving forces behind plant protein development? What are the future application trends of plant protein in 2020? Please follow me to find out.
1. Global market for plant protein
According to Markets and Markets, the global plant protein Markets is expected to be worth US$18.5 billion in 2019, It is expected to grow at a CAgr of 14.0% starting in 2019 and reach US$40.6 billion by 2025. Plant-based protein products are derived from plants such as soybeans, wheat and peas. Plant protein applications include protein drinks, dairy substitutes, meat substitutes, protein bars, nutritional supplements, processed meat, poultry and seafood, baking, food and sports nutrition products. Plant protein applications can enhance the nutritional and functional properties of the product, such as texture, emulsifying properties, solubility, stability and adhesion etc.
The application of plant protein in new food and beverage products has also been increasing in the world. According to Innova's Global New Product Database, which tracks plant protein claims of new food and beverage products worldwide, between 2014 and 2018, the proportion of them continued growing, with the exception of North America, the Middle East and Africa. Despite the decline in North America, the share of new product releases in North America remains one of the world's leading, accounting for 15.4% of total new product releases in 2018. Plant protein claims in Asia were the most significant increase, accounting for 13.4% of all new releases in 2018, an increase of 2.4% from 2014.
2. Market Driving Force of Plant Protein
1）Increased number of new releases
In food and beverage industry, more and more new products will use plant protein as the main highlight of the product. According to innova Market Insights, new food and beverage releases with plant protein claims were tracked globally at a CAgr of + 9 % between 2014 and 2018.
2）Change of consumer eating habits, advocating " clean " diet
Consumers pay more attention to food sources, and plants are what they consider " clean " sources. The trend toward a " clean diet " is largely driven by millennials who prefer healthy, ethical, natural, less processed foods.
On the other hand, consumers' eating habits are gradually changing, they are reducing meats and more prone to vegetation protein. In the uk, the " vegetarian 2020 " campaign was supported by over 300,000 people and many fast-food restaurants and supermarkets in the UK have expanded their offerings to take part in a popular plant-based movement.
3）Large enterprises invest in vegetable protein market
Shandong Kawah Oils
Wonderful Industrial Group
Xinrui Group – Shandong Kawah Oils invetsted USD 45,000,000 in 2016 to establish 4 soy protein isolate production lines with the output of 6000 tons annually based on the 12- year-old soybean oil extracting factory.
China had the largest capacity to process as much as 79 percent of global soy protein isolate, the total capacity is 500000 t/y and the actual producing amount in total is 350000t in 2019.
ADM (US) and DuPont (US) are the two giants in the global market. These companies have made expansion and investment the main strategy for expanding their market in plant protein. In January 2019, ADM expanded its presence in Brazil with the construction of a new soy protein production base in Campo Grande, South Mato Grosso State, Brazil, valued at USD 250,000,000. The company will produce a range of functional protein concentrates and isolates for ADM's current product line.
3. Application Trend of Plant Protein
1）Soy protein is expected to dominate the market in the next 5 years, with the emerging of pea and oat protein as the new trend.
Soy protein is widely used in the food and beverage industry due to the demand for high protein diet and the increasing popularity of soy protein. In a survey of plant protein sources by Aritzon in 1919, soy protein topped the list at US $3.12 billion. According to Innova data, soy protein was the leading ingredient in food and beverage new products announced by plant protein between 2014 and 2018, with 9% of related new products adopted. Soy protein helps lower cholesterol levels, improves metabolism, bone density, and can also reduce the risk of cancer. Soy protein isolate can be used in nutrition bars, meat substitutes, baking products, sports nutrition products and beverages, etc.
Apart from soy, pea protein consumption has increased rapidly in recent years. Global pea protein consumption has doubled from 2015, according to data from food company technical adviser enk Hoogenkamp, to 275000 tons, by 2020. Its consumption will grow 30% to 580000 tons by 2025.
Oat protein is also a kind of great potential plant protein. Oat contents 19% of protein, oat protein is rich in amino acids and essential amino acids, is a high-quality nutritional protein. Oat milk is a newly developed non-dairy vegetable milk. There are many functional similarities between oat milk and milk. Both are creamy and have a smooth texture and consistency. According to Mintel data, the European market in April 2017 to March 2018 listed new products, oat-based drinks and yogurt accounted for 14.8 percent, compared with 9.8 percent a year earlier.
2）Protein ssolate expected to dominate plant protein market in the next 5 years
Protein Isolate contains high Protein content and digestibility. Protein isolates are widely used in protein- and nutrition-related applications such as sports nutrition, protein drinks, and nutritional supplements. In recent years, because of its different functional characteristics, it has been widly used in a variety of beverages and dairy products to cater for athletes, body builders, vegetarians.
3) Sports nutrition, snacks are the application trend
Sports nutrition products and snacks are the trend for future applications. According to Innova Market Insights, the Global New Product Database tracks the launch of a new food and beverage product with plant protein claims, The growth of sports nutrition category is the most obvious, with an average annual compound growth rate of 32% from 2014 to 2018, followed by snack, with an average annual cgr of 14%.
Protein nutrition bar originally belongs to sports nutrition, with the upgrading of consumer awareness, it gradually moved closer to the category of snacks. Today, protein bars are not just for athletes, but also for the average consumer looking for a nutrient bar for breakfast or a daily snack.

With the deepening of people's understanding of healthy food, Soy Protein Isolate is more and more popular. What are some examples of SPI applications in the food industry? What are the advantages of Soy Protein Isolate?
l What is Soy Protein Isolate?
l Application of Soy Protein Isolate in Meat Products
l Application of Soy Protein Isolate in Baked Food
Soybean protein isolate is a full-value protein food additive produced from low-temperature desolubilized soybean meal.Soy Protein Isolate is an important vegetable protein product, which is rich in nutrients and does not contain cholesterol. One of the varieties of protein, it has been widely used in food and other industries, and its protein content is as high as 90%. The digestibility and utilization rate can reach 93% to 97%. Soybean protein isolate contains 8 kinds of essential amino acids and some amino acids exceed the standard recommended by F A O /WHO. It is mainly composed of 11S and 7S globulin, and the protein composition is essential Eight kinds of amino acids are relatively balanced, especially lysine content is the highest.
At the same time, SPI also contains a lot of essential fatty acids, phospholipids, and minerals such as calcium and phosphorus that are beneficial to human health, and does not contain cholesterol. Its efficacy ratio is higher than that of meat. When mixed with other foods, it can significantly improve the nutritional value of the original food.
1. Minced meat products belong to the general public meat products, and the use of Soy Protein Isolate is small. For minced meat products such as meat patties, minced meatballs, dumplings and steamed buns, they are usually processed by roasting, frying, steaming and boiling. The processing temperature is high. It has good oil absorption properties.
2. Soy Protein Isolate can be used as an additive to improve product texture (reduce free fat). It can not only produce meat-like taste, but also enhance water holding capacity, reduce pie cooking shrinkage, improve yield, and reduce costs. At the same time, it can improve the nutritional value of the product.
When producing bread, adding no more than 5% Soy Protein Isolate can increase the volume of bread, improve the color of the skin, and have obvious effects on the sensory quality and nutritional value of bread (for example, it can make bread products The protein content increases, the volume increases, the texture is soft, the flavor is good, and the nutritional supplementation effect is obvious), and the shelf life of the product can also be extended; but if the amount of Soybean protein isolate added is too large (8%-12%), it will affect The tissue state and sensory quality of the bread will reduce the volume of the bread, thicken the skin, deepen the color, and harden the texture, and the effect is not good. Therefore, when using, the amount of Soybean protein isolate should be paid attention to.
If you are looking for a good quality and reasonable price of soybean protein isolate products,Xinrui Group can provide you with the best

The company at this stage vigorously develops wheat, soybean two major circular economy industrial chains.
The group began to develop 300,000 tons of wheat processing industry in 2007. The industry chain is to give priority to extracting high value-added refined flour from wheat. Vital Wheat gluten and superior starch were extracted from secondary flour with lower added value by downstream workshop, (Vital Wheat Gluten is used in high-gluten flour compounding, vegetarian food processing, and superior starch is used in the processing of Vermicelli, cold powder and other products.) The starch pulp composed of residual secondary starch and Pentosan was used to extract food-grade alcohol and medical alcohol through saccharification and fermentation in the production line of alcohol.
On the basis of summarizing the successful experience of wheat industry chain, the company developed 180,000 tons of soybean deep processing industry chain in 2015. Non-GMO soybean oil and food-grade soybean meal were produced from non-GMO soybean. Soybean meal can be used in food processing industry such as 1,000-page Bean Curd, meatball, ham, chafing dish and so on, it can be used in industries such as ketchup and dietary supplement.
The high concentration organic wastewater from the production of wheat and soybean industry chain was transported to the wastewater treatment plant. The remaining high-concentration organic wastewater is converted into biogas by anaerobic fermentation, and the biogas is purified and desulphurized, and then used in power generation or steam supply industry chain. After anaerobic treatment of wastewater by aerobic treatment and then advanced treatment to achieve the recycling water standard as heat and power co-generation boiler make-up water, industrial chain recycling water. The sludge from sewage treatment was fermented at high temperature after dehydration and processed into organic fertilizer, which was used to improve the soil remediation and improve the yield and quality of crops. The wheat and soybean produced by the base are used as raw materials in the industrial chain, thus realizing the development of closed-cycle economy from wheat and soybean planting, intensive processing, sewage treatment to soil improvement and rehabilitation of the planting base.

With lifestyle changes in recent years, the number of prepared meat products is quietly increasing, ranging from a variety of semi-prepared chicken nuggets, seasoned meat steaks and barbecue products to convenience store staples such as kebab and bento. Through the retail end, prepared meat products are increasingly infiltrating the domestic consumption of the Chinese public, well is gradually becoming a consumer popular. In regulate the development of meat products, soybean protein is a kind of commonly used additives, not only can complement necessary hydrogen acids necessary for human, and mesh has good features such as foaming, emulsification and gel, so it can obviously improve the food's taste, increase elasticity, oily food and water retention, improve the storage performance of food, etc., can reduce the production cost at the same time, In regulate meat processing has the important role
Soybean flour mostly "defatted soybean" trends, because of its protein content is low, so the price is straight, used in meat products, can keep 2 times their own weight of water and flour emulsify material can keep the same weight of cerebral fat class material during hot working out oil, soy meal less functional, There are many shortcomings in taste and flavor, and many restrictions on the range and usage.
Soy Protein Concentrate
Soy Protein Concentrate’s protein content of about 70%, most used in meat products. Soybean concentrated heavy force since the emulsifying gel proportion is protein: water: fat = 1:4:3, It can improve the taste and structure,to improve protein content of meat products.
Isolated Soy Protein
Soy Protein Isolate is a kind of protein produced from low temperature desoluble soybean flour. The protein content is more than 90%, and there are nearly 20 kinds of amino acids, including essential amino acids for human body. It is rich in nutrition and does not contain cholesterol. It is widely used in prepared meat products.
Textured Soy Protein
Textured Soy Protein is made of defatted soya powder, soy protein concentrate or soybean protein isolate as raw materials by mechanical and heat action such as mixing, extrusion and chemical. These proteins have a certain fleshy taste sensation. Therefore, it has special application in meat conditioning and can replace some lean meat raw materials.
1. Water-retaining property
The water retention of soy protein plays an important role in meat production, especially its ability to absorb, combine and bind water in the processing of minced meat products, which can not only retain the juice of raw meat, increase the taste and flavor of products, but also increase the yield of products. The water retention of proteins is also affected by many factors, such as viscosity, pH, ionization strength and temperature. Ma Yuxiang studied the effect of the addition of soy protein isolate on salt-soluble muscle protein heat-induced gel, and the experimental results showed that the addition of soy protein isolate made the ultrastructure of the mixed protein gel rough, reduced the strength of the mixed protein gel, but improved the water-retaining capacity of the gel.
2. Emulsifying property
Emulsifying soybean protein hydrophilic, lipophilic determines its emulsifying stability, soybean protein is a surfactant, it can reduce the surface tension of water and oil, and reduce the surface tension of water and air, so it is easy to form a more stable emulsion. The emulsified oil droplets are stabilized by the heavy white material that accumulates on the surface of the oil droplets, forming a protective layer. This protective layer can prevent the accumulation of oil droplets and the destruction of the emulsification state, so that the emulsification performance is stable. In the preparation of baked food, frozen food and soup food, a large number of studies have been reported on adding human soy protein isolate as emulsifier to stabilize the product state.
3. Caking property
Protein molecular bonding, strong solubility and absorption ability make it has caking property, It apply to adjust food properties. When protein heatto 80 ℃, proteinwill happen business solution or analysis solution, molecular volume increases, viscosity increases, more than 90 ℃ viscosity decreases, pH in six to eight, protein structure is the most stable, maximum viscosity; Above 11, the viscosity is sharply reduced due to the breakdown of protein bonding.
4. Gel property
When meat products containing soy protein are heated, they will form a salty gelatinous structure, which has an obvious effect on the water retention and taste of the products due to the hardness, elasticity, flake and texture of the products. The formation of gel is affected by many factors, including heating time, temperature and concentration of soy protein solution.
Soybean protein contains essential amino acids, which can strengthen the nutritional composition of prepared meat products and play an important role in improving the quality of prepared meat products.
1.High cost effective protein source with enhanced nutrition
Soybean protein has been widely used in the preparation of meat products because of its low price and good protein quality. Adding soybean protein to all kinds of frozen meat products can not only improve the ratio of protein, but also make the nutrition of protein more comprehensive and reasonable.
2.Flavoring in prepared meat products
Soybean protein contains a small amount of fatty acids and carbohydrates, after heating will produce unique aroma, and regulate the products sometimes raw meat (fish) or ingredients and due to the processing of the I art, such as sterilization produced some of the unpleasant smell, may cause consumers antipathy, soy protein unique fragrance smell to above has certain masking effect, Therefore, soy protein has a certain flavoring effect.
3.Soy protein can improve the structure of prepared meat products
Soybean protein has good gel properties and bonding properties, which can effectively improve the texture of the product, enhance the elasticity and hardness of the product, and make the product compact in structure and better in taste. More meaty, especially in fast east meat country, live meatballs and meat products are more sold.
4.The emulsifying property of soybean protein was used to solve the problem of oil coming out of water of prepared meat products
Water, oil is one of the most common problems in the process of cooking in the conditioning of internal products, using the emulsification characteristics of soybean heavy white, so that the water and oil form a grain for the field network structure, so that the water and oil in the conditioning of internal products are very south, in the storage and cooking process of water, oil hidden less.
Two important processes for processing prepared meat products are processing raw meat and curing ingredients. According to the processing characteristics of prepared meat products, there are usually the following adding methods:
Large pieces of fresh meat are added with pickling solution. The soybean protein soluble brine brine is added by injection, and then other processing methods are carried out. This method can make protein evenly distributed in meat. Soy protein generally accounts for 2 to 6 percent of meat products by weight.
That is, soybean protein products in chopping, rolling, stirring process at the beginning of the state of dry material evenly added, but the dry material should be added to the meat products before fat.
In order to make full use of the functional characteristics of soybean protein, soybean protein products had better be hydrated before adding and made into a dispersion containing 18% of protein. The water ratio is soybean powder: water is 1:(1.5~1.8), protein concentrate: water is 1:(2~2.5), protein isolate: water is 1:(3.5~4).
Regulate meat as an emerging industry, its accessories added by the wide attention of the society, as a result of the good function of the soy protein, a variety of features, has become an important conditioning meat processing accessories, the size of the amount of its flavor, texture, structure plays an important role, If add a little amount of product caused not harmonious, not masking bad smell flavor, not to reach the effect of flavouring, And it will lead to loose product structure, soft taste and other adverse results; On the contrary, excessive use of the product will cause too strong bean smell, taste hard and other adverse phenomenons, the specific amount of soy protein to be added according to the quality of soy protein and the type of product to be developed to decide comprehensively.
The application scope of soy protein in meat products is becoming more and more extensive, because of its good nutritional value and functional properties.
Adding soy protein in meat products can not only improve the product yield, but also improve the taste of the product. Soy protein has good gel property and water retention. When heated over 60℃, the viscosity increases rapidly, when heated to 80-90℃, the gel structure will be smooth, so that soy protein entering into the tissue of meat can improve the taste and quality of meat greatly. Soybean protein has both hydrophilic and hydrophobic properties which can easily combine with water and saturated with oil, so it has good emulsifying feature. This processing characteristic is very important in the processing of meat products with high fat content, which can restrain the lost of fat to stabilize the product quality. Although soy protein plays an important role in meat processing, in order to control soy protein in meat products replacing of whole meat and prevent adulteration, many countries have restrictly addition of it to ensure the healthy development in meat process. In view of the fact that there is no effective method for the determination of soy protein in meat products, it is great significant to study the detection method of soy protein in meat products.
2 Advantages of applying soy protein in meat products
Meat is reagarded as the best source of protein, owing to its high nutritional value and good taste in western countries. In order to make full use of animal resources, meat processing enterprises not only use protein-rich lean meat, but also often use fat-rich chicken skins, fat and other low-value materials. For example, Bologna sausages, Frankfurt sausages, salami and other meat products have relatively high content of fat. For example, Frankfurt sausages has about 30% of the intestine fat content and raw pork intestine fat content of up to 50%. High fat additions make meat processing more difficult. For example, in the production of emulsified sausages with high fat content, it is easy to form the phenomenon of oil. In order to control the oiling phenomenon of sausages in the heating process, it is necessary to add emulsifiers or accessories with the function of water-preserving oil. Usually, meat products as a "emulsifier" is the meat protein, but once the amount of lean meat added is relatively small, fat content is large, the entire emulsification system will lose balance, some fat in the heating process will be isolated. This can be addressed by adding non-meat protein, thus soy protein the best option. In meat processing, there are several other important reasons for adding soy protein. Medical health experts believe that low-fat meat products are healthier, fatty meat products are more likely to cause high blood pressure and other related diseases. Low-fat meat products will become the future development trend of meat products. Developing low-fat meat products is not simply a reduction in fat addition, which also requires a comprehensive consideration of the taste of product. As fat plays an important role in juicy, tissue structure and other aspects of meat products, once reducing the amount of fat, the taste of meat products will be affected.Therefore, in the development of meat products, "fat substitute" is necessary, it can reduce the fat content of the product on the one hand, on the other hand it can ensure the taste of the product. By adding soy protein, not only can reduce the calories of the product, but also can preserve the flavor and taste of the product to the greatest extent. Wheat protein, egg white and soy protein are better fat substitutes, while soy protein is more popular because of its good processing properties. Another reason to add soy protein is that it's much cheaper than meat protein. Adding plant protein can greatly reduce the production cost of meat products. In the actual production, because of the high price of meat protein, in order to improve the cost performance of the product, the low price of soy protein is often the first choice of production enterprises. In addition, in economically backward areas, animal protein is very scarce, soy protein and other plant protein is the most important source of protein. Soybean protein is the most widely used plant protein. Its main advantages lie in: First, smaller peculiar smell; Second, the price is low; Thirdly, high nutritive value ( soybean protein is rich in essential amino acids, and its digestibility and absorption rate are high in human body ) Fourth, excellent processability (better hydration, gelation and emulsification); Fifth, the use of meat products can improve product appearance quality and palatability. Soy protein can be divided into soy protein concentrate, soy texture protein, soy protein isolate and so on according to their components. Each protein product has different functional properties, which are applied to different types of meat products according to different functional properties. For example, soy protein isolate and protein concentrate are mainly used in some emulsified sausages. Compared with soy protein concentrate, soy protein isolate is rich in raffinose and stachyose oligosaccharides, which can easily cause bloating. Tissue proteins are often used in meatballs and pies. In addition, soy protein isolate ( SPi) and soy protein concentrate ( SPc) are often used in some injection-type meat products to improve the hardness, slicing and yield of the products. Because soybean whole flour has strong beany smell and rough taste, Ruiqianjia soy protein isolate and protein concentrate are better than soy whole flour in food processing.
3 Requirements and problems of soy protein applying in meat products
Too muchh addition of soy protein can cause allergies in some groups of people, in order to prevent soy protein being used as pure whole meat in meat process, to prevent adulteration and ensure the healthy development of the meat industry, many countries have strictly restricted the addition amount of soy protein. Some countries have strictly restricted the amount of soy protein added to meat products. In the United States, for example, the amount of soy flour and soy concentrate protein in sausages can not exceed 3. 5%, the addition of soy protein isolate should not exceed 2%; Soy flour, soy protein concentrate and soy isolated protein in beef patties and meatballs should not be over 12%. In salami, many countries have strict restrictions on the amount of addition soy protein, Spain requires less than 1%; French food laws require less than 2 per cent.
The U.S. labeling requirements for soy protein in meat products are as follows:
When the soy protein addition is less than 1/13, it needs to be identified in the ingredients list; When the addition is close to 10%, it should not only be identified in the ingredients list, but also be commented next to the product name; When its content is more than 10%, soy protein is not only identified in the ingredients list, but also in the product attribute name.
Many countries have strict requirements for the addition of soy protein and the marking of meat products. But there is no effective way to detect soy protein. Because current testing of proteins is mainly determined by detecting nitrogen content, plant proteins and meat proteins are difficult to distinguish. In order to further regulate the use of soy protein in meat products, a method to detect plant protein content is needed. In the 1880s, many food scientists studied the detection of soy protein content in meat products. The enzyme-linked immunoassay method is recognized as a more authoritative test, but the standard of the soy protein added is required to use this method.

At present, there is no effective detection method for soy protein in meat products, so it is urgent to develop a new test method for the rapid, convenient and accurate discrimination of meat adulteration.
