Nutritional value of soybean skin

1. Nutritional value of soybean hull

Soybean hull contains some protein and a lot of cellulose, as well as some trace elements such as phosphorus and iron. Usually, it can be used as medicine, and it is mostly used to make some livestock drinks, which has a particularly high nutritional value. In addition, bean skin also contains some trace elements such as nitrogen, phosphorus and potassium, which can be directly used as flower fertilizer after decomposition, and the effect is also obvious.

2. Medicinal efficacy of soybean hull

After the soybean shell is used as medicine, it can reduce qi and reduce fever, and it can also moisten the intestines and relax the bowels. Can be used for human habitual constipation and children constipation. In addition, bean skin can strengthen the spleen and stomach, and can also stop diarrhea. It also has a good therapeutic effect on human common diseases such as spleen deficiency and diarrhea, and the therapeutic effect is very obvious.

3. Special use of soybean hull

When soybean hull is used to treat human habitual constipation, it can be ground into powder, take10g each time, wash it with clear water and add water for decoction, then take it instead of tea and take it orally within one day. To treat human diarrhea with soybean shells, it is necessary to fry soybean shells into charcoal and grind them into powder, taking three to nine grams each time and sending them with boiling water twice a day.

Second,

I believe you must be very familiar with soybeans. Soybean is a common bean. Soybean is not only edible, but also nutritious. Soybean is rich in plant protein and a variety of trace elements needed by human body. Eating soybeans regularly can play a good health care role, so soybeans are loved by everyone, and the skin of soybeans is also rich in nutrition. Here we will introduce you to the nutritional value of soybean skin.

Nutritional value of soybean skin

Soybean hull is a by-product in the process of soybean oil production, accounting for 10% of the total soybean volume and 8% of the total soybean weight. Soybean skin is mainly the substance wrapped in the outer layer of soybean, and its color is beige or light yellow. It is obtained by two processing methods: hot peeling or oil processing, crushing and sieving. The main components are cell walls and plant fibers, with crude fiber content of 38%, crude protein 12.2%, calcium oxide 0.53%, phosphorus 0. 18% and lignin content less than 2%(NRC, 1996). In addition, there are two kinds of soybean skin products suitable for animal feed: soybean crushed feed and soybean crushed waste. The soybean crushing feed consists of soybean skin, processed soybean powder and crushed materials at the tail of the crusher. The crude protein content of the feed is 13%, and the crude fiber content is about 32%. The crushing waste of soybean skin consists of soybean skin and cotyledons attached to dry skin. The crude protein content of this by-product is 1 1%, and the crude fiber content is about 35%.

2 advantages of soybean hull

1 soybean hull contains a lot of crude fiber, which can replace the low-quality straw and hay in the coarse feed of herbivores.

Straw has poor palatability, low crude protein and mineral content, and high lignin content. In the process of drying grass into hay, most nutrients are lost due to chemical and mechanical effects, and the utilization rate of herbivores is low. The NDF of soybean hull is 63%, ADF is 47%, and the lignin content is only 1.9%. The water quality of cellulose is an important factor in the digestion of cellulose in feed. Because of the high crude fiber content and low lignification degree of soybean skin, daxianpi can replace straw and hay. The results of HSU( 1987) test showed that the dry matter digestibility of soybean skin in nylon bags was 90.3% in 27 hours and could be completely digested in 36-48 hours. Owen( 1987) experiment showed that the digestibility of NDF in soybean skin was as high as 95%. Kedey and Williams( 1995) pointed out that digestible fibrous by-products (such as soybean hulls) are good roughage for grazing in winter, which is better than feeding hay in winter.

Soybean hull contains a proper amount of protein and energy, which can replace some concentrate supplements for ruminants.

The crude protein content of soybean skin is 12.2%, which is higher than that of corn (10%) and lower than that of wheat bran (17. 1%). The net energy of soybean hull is 8. 15MJ/kg, which is higher than that of wheat bran (6.72MJ/kg) and lower than that of corn (8.23MJ/kg), so soybean hull can replace a certain amount of corn and wheat bran. Adding soybean hull can also reduce the metabolic diseases of ruminants. Adding grain energy feed to low-quality roughage, because the grain feed contains a lot of starch, it ferments rapidly in rumen, the pH of rumen fluid drops, and the microbial flora is disordered, which leads to acidosis, thus affecting the digestion of feed dry matter and crude fiber. Replacing part of grain feed with soybean hull can not only reduce acidosis caused by high-precision diet and form favorable rumen pH value, but also stimulate the rapid growth of fiber-degrading microorganisms in rumen fluid and enhance fiber-degrading activity.

In the above article, we introduced a common bean, that is, soybean. We know that soybeans are not only delicious but also nutritious. The above article introduces the nutritional value of soybean skin in detail for us. I believe everyone has mastered it.
