Research on the nutritional composition and value of soy protein isolate

Soy protein isolate is a full-price protein food additive produced from low-temperature desolubilized soybean meal. The protein content of soy protein isolate is more than 90%, there are nearly 20 kinds of amino acids, and it contains essential amino acids for the human body. It is a plant-based complete protein, rich in nutrients and contains no cholesterol. It is known as "green dairy cow" and "plant meat".

The nutritional value of soy protein is equivalent to that of animal protein, and its genetic structure is also closest to human amino acids. It is one of the few plant proteins that can replace animal protein. It has the characteristics of high protein, low fat, increasing calcium and lowering cholesterol.

The difference between protein isolate and protein concentrate

The process of protein isolation is relatively complex and almost removes most of the insoluble protein, so the protein content is relatively high, generally more than 90%.

The process of concentrated protein is relatively simple. In the process, only insoluble protein is removed, and part of the fiber is not removed. The protein content is generally 65%.

Nutritional composition of soy protein isolate

There are nearly 20 kinds of amino acids in soy protein isolate, and it contains 8 kinds of essential amino acids for the human body.

Soy Fiber: The Invisible 'Hero' in Canned Foods

图片
 Soybean fiber is mainly derived from by - products generated during the soybean processing, such as soybean dregs and soybean skins. These materials, which were originally likely to be regarded as waste, have transformed into soybean fiber with a variety of excellent properties after a series of complex and sophisticated extraction processes. Currently, there are diverse extraction methods for soybean fiber, mainly including physical methods, chemical methods, and biological methods. In the large family of canned foods, whether it is delicious meat cans or fresh fruit and vegetable cans, soybean fiber plays an indispensable and important role in improving the quality and enhancing the nutrition of canned foods. Magical effects of soybean fiber in canned foods Improving Texture and Taste Soybean fiber has unique gel properties and extremely excellent oil - holding and water - retaining capabilities, and this characteristic is demonstrated most vividly in canned meat products. When ...

Emulsified Soy Protein Isolate: An Innovative Force in the Food Industry

图片
Emulsified soy protein isolate represents an innovative achievement in the field of soy protein isolates. It starts with high-quality soybeans and undergoes multiple meticulous purification processes to remove non-protein components such as fats and carbohydrates from the soybeans, resulting in an extremely pure soy protein. The finished product appears as a fine powder with uniform color and an exceptionally high protein content, typically exceeding 90%, far surpassing that of ordinary soy protein products. In terms of advantages, emulsified soy protein isolate boasts superior emulsification stability, rapidly forming a stable emulsion in oil-water systems and preventing oil droplet aggregation and layering. In baked goods, it effectively emulsifies fats, ensuring uniform internal structure, soft texture, and extended shelf life for products like bread and cakes. Its outstanding nutritional enhancement effect is also remarkable. As a high-quality plant protein, it is rich in essential...

The Role of Soy Fiber in Sauces

图片
Sauces play an indispensable role in our diet. Whether it is ketchup that adds color and flavor to dishes or meat sauce that gives dishes a unique flavor, they all add rich flavors to our dining tables with their unique charm. And soy fiber also plays a key role in these sauces, contributing to improving the quality and optimizing the taste of sauces. Thickening effect Soybean fiber can increase the viscosity of sauces, giving them an appropriate flowability and texture. For example, when making salad dressing, adding soy fiber enables the dressing to adhere better to the surface of vegetables. It won't be too thin and runny, thus enhancing the eating experience. In ketchup, it can also make the ketchup maintain a certain shape when squeezed out of the bottle and not quickly flow and deform. Improving taste Soy fiber can endow sauces with a rich taste. It can make the taste of the sauce more full-bodied and layered, avoiding a too single and plain taste. Take broad bean paste as an...
