The straw stalk and reed belong to the herbaceous family and have medicinal value. Carotene has effects of suppressing immunoreaction of immunocompetent cells, quenching peroxide causing immunosuppression, maintaining fluid fluidity of membrane, maintaining membrane receptor state necessary for immunologic function, and releasing immunoregulatory molecule. The spirulina powder can be classified into feed grade, food grade, special purpose, etc. The feed-grade spirulina powder can be used for aquaculture and livestock breeding, and the food-grade spirulina powder is used for health food and added into other foods for people to eat. The cooked soybean powder is powder prepared by frying and grinding soybeans, and the contained unsaturated fatty acid and soybean lecithin can increase the elasticity of blood vessels and prevent the blood vessels from being broken due to the aging of the blood vessels; the cooked soybean powder contains dietary fiber which can increase satiety of human body and promote defecation, and contains high-quality vegetable protein which can supplement amino acid required by human body.
An amino acid is a compound in which a hydrogen atom on a carbon atom of a carboxylic acid is substituted with an amino group, and the amino acid molecule contains both amino and carboxyl functional groups. Amino acids, like hydroxy acids, can be classified as α -, β -, γ -, w-amino acids according to the position of the amino group attached to the carbon chain, but the amino acids obtained after proteolysis are all α -amino acids, and only twenty, which are the basic units constituting proteins.
Minerals are compounds or natural elements naturally occurring in the crust of the earth. Also called inorganic salt, is a general term for inorganic substances in human and animals. Is a general term for various elements which are necessary for forming tissues of human bodies and animals and maintaining normal physiological functions, and is one of seven essential nutrients for human bodies and animals. Minerals, like vitamins, are essential elements for the human body.
The bacillus subtilis is active substances such as subtilin, polymyxin, nystatin, gramicidin and the like generated in the growth process of bacillus subtilis and has obvious inhibiting effect on pathogenic bacteria or conditional pathogenic bacteria of endogenous infection. The Bacillus subtilis can stimulate the growth and development of animal immune organs, activate T, B lymphocytes, increase immunoglobulin and antibody levels, enhance cellular immunity and humoral immunity, and improve population immunity.
