What is Soy Protein Isolate and Soy Fiber

Soy protein isolate is a kind of plant protein with the highest content of protein -90%. It is made from defatted soy meal by removing most of the fats and carbohydrates, yielding a product with 90 percent protein. Therefore, soy protein isolate has a very neutral flavour compared to other soy products. Because most of the carbohydrates are removed, the intake of soy protein isolate does not cause flatulence.

Soy protein isolate, also known as isolated soy protein is used in the food industry for nutritional ( increasing protein content), sensorial ( better mouthfeel, bland flavour) and functional reasons( for applications requiring emulsification, water and fat absorption and adhesive properties).

Soy protein is used in following food products:

Meat processing, frozen products,poultry and fish products

Meat alternatives

Tofu

Baked foods

Soups,sauces and prepared foods

Meal replacements,breakfast cereals

Energy and protein bars

Weight loss ready-to-drink beverages

snacks

Applications of Soy Fiber

Characters of Soy Dietary Fiber:

-High water binding ability as 1:8 at least;

-Stable characteristics;

-Ability of keeping (supporting) effects of emulsifier;

-Insolubility in water and oil;

-To form gel together with soy protein.

Advantages to Use Soy Dietary Fiber

Thanks to the high water-binding ability, it increases the yield of meat production greatly, for the purpose to reduce the production cost. And the thermal stability of edible fiber under high temperature sterilization also makes it used widely in the production of many kinds of canned food. Besides this, it cleans gall bladder, prevents forming stones and helps to reduce the cholesterol in human blood.

Soy Dietary Fiber is recommended in the following kinds of products:

-Cooked Sausages, Cooked Hams; Half-smoked, boiled-smoked sausages;

-Minced meat;

-Chopped semi-prepared meat;

-Canned food, like Luncheon Meat, Canned Tuna;

-Tomato Mix, Tomato Paste, Tomato Sauce, and other Sauces recommended.
