Is soy protein a high-quality protein?

Recently, the doctor suggested that we should drink more milk, eat more eggs, and drink less porridge during this special period, which caused a lot of controversy. I found that many people do not understand the essence of eggs, milk and porridge. The essence of porridge Carbohydrates, that is, sugar, are the most direct source of energy for the human body. Milk and eggs are the representatives of protein foods, which can enhance human immunity. But in our country, another protein-rich food, soy, there has always been a lot of controversy about whether soy protein is high-quality protein, and it seems like it could spark a world-class debate.


Many people around me deny that soy protein is high-quality protein, and the reason given is that it is vegetable protein, and plant protein is not high-quality protein. High-quality protein. Here we do not talk about digestion and absorption. But I don't think it's reasonable to deny that soy protein is a high-quality protein just because it's a vegetable protein.


First, after protein enters the body, it is decomposed into amino acids by protease in the stomach and small intestine, and then absorbed by the body. There are more than 20 kinds of amino acids that make up the human body, most of which can be synthesized in the body, but 8 of them cannot be synthesized by the human body and must be provided by food, so they are also called "essential amino acids". These 8 essential amino acids are: Tryptophan, Threonine, Methionine, Valine, Lysine, Leucine, Isoleucine and Phenylalanine.

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...

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...
