Taking degreased silkworm chrysalis as the raw material, micro-solubility protein and polypeptide can be gained through hydrolysis. The color is faint yellow, and the ninhydrin reaction is positive.
(1)The contents of protein and polypeptide are high, whose total amount are above 75%. (2)Silkworm chrysalis protein is a complete protein, so it has a wide range of amino acids, with eight kinds of essential amino acids balanced whose proportion is appropriate and in line with the model of the United Nations Food and Agriculture Organization and World Health Organization (FAO/WHO).The silkworm chrysalis protein contains rich major and minor elements, among which the content of zinc is up to 19.025mg/100g. (3)This product has high nutritive value, which can be widely applied to nutritional health food products (electuary, capsule, nutritive wine, food for old men, baby food, etc.); used in candies, cakes, fortifier foods, various dried gravy noodles and condiments (sauces, soy sauce, vinegar and a variety of soups); It can be also used as the basic raw materials for medical protein, polypeptide, separating and purifying various single amino acids.
