Application of soybean protein isolate

Nowadays, more and more people begin to pay attention to health preservation, and cereals are also more than fine grains, which are respected by more and more ordinary people. Soybeans are one of them, including soybeans, big red beans, green beans, soybeans, black beans and other foods.

Soybean food is rich in nutrition. Its three energy supply components are balanced, with a certain amount of carbohydrates. At the same time, it is also rich in high-quality plant protein and fat, which is not biased at all. At the same time, the content of dietary fiber in soybean is also high, and there are a wide range of minerals and vitamins. It can be said that it is a high-quality food material that can never be missed.

We take the most common soybeans as an example. 100g soybeans (dry) contain 35g protein, 16g fat, 18G carbohydrate and 15g dietary fiber; There are many kinds of minerals. 100g soybeans (dry) can provide 1503mg potassium, 465mg phosphorus, 191mg calcium, 199mg magnesium, 8.2mg iron, and rich in manganese, zinc, selenium and other elements. Compared with many food materials, they have higher nutritional value.

Soybean also contains a special ingredient "soybean isoflavones". Soybean isoflavones are antioxidant substances, which can promote estrogen secretion and delay ovarian aging. For female friends, they are a magic weapon to delay menopause and maintain youth; However, if male friends ingest too much, it may lead to endocrine disorders and, in serious cases, breast hyperplasia. 20G soybeans are not equal to 20g "bean products", such as tofu, soymilk and dried tofu. The replacement of soybean products is about 500~700ml soymilk, a large piece of tofu and about 100g dried tofu.

Many friends think that the fat content in soybeans is high. In fact, the fat content in soybeans can only be said to be "appropriate", and most of these oils are very beneficial to the human body, belonging to "unsaturated fatty acids". Unsaturated fatty acids are very different from the saturated fatty acids we usually eat from fat meat and streaky pork, or the "trans fatty acids" in fried foods and puffed snacks. They can improve the content of high-density lipoprotein in blood Reduce the content of low-density lipoprotein, maintain the stability of serum cholesterol, and help regulate blood lipids. N3 fatty acids in soybeans also help fight cell inflammation and have potential anticancer effects.

The dietary guidelines also recommend that the daily intake of soy food should be about 20g. 20g is not much, which is about the amount of two small handfuls. Although soy is particularly rich in nutrition, it is not a food that the more the better. Among them, the content of dietary fiber is high, and the content of oligosaccharides is high, which is easy to cause indigestion and inhibit the absorption of other nutrients, which will increase the burden of digestion for people with weak intestines and stomach, For people with weak liver and kidney, it will also increase the metabolic load; The content of calories, fat and carbohydrates in soybeans is not low. Eating too much may lead to excessive intake of sugar and fat, which has adverse effects on the human body.
