Description

A kind of additive for infant food
Technical field
The present invention relates to a kind of for food additives of infant and preparation method thereof, belong to foods processing technique neck Domain.
Background technology
Beans refer to it is all can produce the legume of beanpod, meanwhile, be also commonly used to call pulse family Papillionoideae in The legume crop for being used as edible and feed.In hundreds and thousands of kinds of useful legumes, the beans widely cultivated so far Crop does not exceed 20 kinds.
Beans and bean product are very high containing protein, typically between 20~40%, with soy content highest.Beans and beans system The protein of product not only contains highest, and quality might as well.The methionine composition of bean protein is similar to animal protein.It is close Human body needs, the lysine wherein more lacked in cereal rich content in beans, therefore preferably edible with cereal mixture.
The nutritive value of beans is very high, and China's traditional food is particular about " five cereals are preferably foster, lose beans then bad ", means Five cereals are nutritious, but no bean or pea will disequilibrium.Modern nutriology is also demonstrated that, Food Legume food is adhered to daily, As long as the time of two weeks, human body can just reduce fat content, increase immunity, reduce ill probability.Therefore, many nutrition Scholar appeals, the animal foods such as a certain amount of meat are replaced with bean food, is to solve people's malnutrition and battalion in city Support the best method of surplus double burden.
Protein content contained by beans is high, quality is good, and its nutritive value, close to animal protein, is best plant Albumen.Beans contains a variety of essential amino acids, and amino acid composition is reasonable, and the composition of amino acid, close to the need for human body, is me The good source of protein in state's people's meals.Fat contained by beans up to 18%, thus can be eaten using soybean as highest The raw material of oil, other beans are fatty less.Beans sugar content is higher with broad bean, red bean, mung bean, pea content, be 50%~ 60%, soybean sugar content is less, and about 25% or so.Therefore, the heat of beans supply is also at a relatively high.Vitamin is with B in beans Family vitamin is at most, higher than cereal content.In addition, also containing a small amount of carrotene.Beans is rich in nothings such as calcium, phosphorus, iron, potassium, magnesium Machine salt, is rare high potassium in meals, Gao Mei, low-sodium diet.
There is also protease inhibitors in beans, it can suppress the activity of trypsase, chymotrypsin, pepsin, with Trypsase is the most universal.Beans also contains agglutinin.It is a kind of glycoprotein, steam treatment 1 hour or high pressure are steamed at ambient pressure Vapour processing can be allowed to inactivate for 15 minutes.Beans containing agglutinin, it is not heated be allowed to destruction before it is just edible, can cause into The symptoms such as trencherman's Nausea and vomiting, severe patient even can cause death.
