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).
