Application of soy protein isolate in food
Due to the balance of amino acids in soy protein, it is almost consistent with the composition of amino acids recommended by FAO and WHO. In particular, the content of lysine in soy protein is higher than other cereal products. Therefore, its application in noodles can improve the protein content of products. In addition, according to the principle of amino acid complementarity, the addition of soy protein can also increase the content of protein.Because of its processing characteristics, it can increase the color and flavor of noodles in processing,extending the shelf life of flour products.
🍜Application in noodles🍜
Add 7-9% soy protein isolate to the flour. The protein content and wet gluten content of flour can be improved significantly. Therefore, the rheological characteristics of the dough were improved: the noodles were made with good toughness, good taste and no obvious bean smell. It not only increases the nutritional value of noodles, but also improves its processing characteristics.
🥞Application in bakery products🥞
High dispersible soy protein isolate in baked food can increase protein content and improve product quality. For example, the processing characteristics of soybean protein isolate, such as hygroscopicity,emulsifying, dilatancy and blistering, can improve the nutritional value and hygroscopicity rate of bread, increase the volume of bread, improve color and texture, increase the flavor of bread, prevent bread from stiffing, and extend the shelf life. When soybean protein was added to bread below 7.5%, the sensory changes of bread were not significant, and those greater than 7.5% had a significant impact on bread.
In production of cake,adding soy protein isolate can improve the foaming and hygroscopicity of the cake, making the cake fluffy, delicate, good-looking and taste good, not hard. In addition, soy protein isolate is oil absorbent and can be used in the production of pastries and pastries to make products soft and delicious. In the production of biscuits, about 15% to 30% protein isolate is added into the raw materials, which can not only improve the protein content, increase the nutritional value, but also increase the crispness of the biscuits and play a role in preserving freshness.
🍝Application in instant noodles 🍝
When the active soy protein powder is added to the instant noodles, it has a special smell when chewing, making it more palatable. Added active soy protein powder instant noodles taste good, the brittleness of noodles decreased significantly.This is because soy proteins are gelatinous and so on.
As the amount of soybean protein powder added increases, the oil content of instant noodles will decrease to some extent. This is because the protein will undergo thermal degeneration and form an oil layer on the surface of Fried pasta.
The oil content decreased by 4.3% when the 3% protein was added.
The oil content decreased by 5.7% when the 4% protein was added.
The oil content decreased by 6.7% when the 5% protein was added.
The oil content decreased by 7.7% when the 6% protein was added.
