Vitamins:
Vitamin A:
Retinol. Carotene compounds responsible for transmitting light sensation in the
retina of the eye. Deficiency leads to night blindness.
Beta carotene: An
antioxidant which protects cells against oxidation damage that can lead to cancer.
Beta carotene is converted, as needed, to vitamin A. Food sources of beta
carotene include vegetables such as carrots, sweet potatoes, spinach and other
leafy green vegetables; and fruit such as cantaloupes and apricots. Excessive
carotene in the diet can temporarily yellow the skin, a condition called
carotenemia, commonly seen in infants fed largely mushed carrots.
Vitamin B1:
Thiamin, acts as a coenzyme in body metabolism. Deficiency leads to beriberi, a
disease of the heart and nervous system.
Vitamin B2:
Riboflavin, essential for the reactions of coenzymes. Deficiency causes
inflammation of the lining of the mouth and skin.
Vitamin B3:
Niacin, an essential part of coenzymes of body metabolism. Deficiency causes
inflammation of the skin, vagina, rectum and mouth, as well as mental slowing.
Vitamin B6:
Pyridoxine, a cofactor for enzymes. Deficiency leads to inflammation of the
skin and mouth, nausea, vomiting, dizziness , weakness and anemia.
Folate (folic
acid): Folic acid is an important factor in nucleic acid synthesis (the genetic
material). Folate deficiency leads to megaloblastic anemia.
Vitamin B12: An
essential factor in nucleic acid synthesis (the genetic material of all cells).
Deficiency leads to megaloblastic anemia, as can be seen in pernicious anemia.
Vitamin C:
Ascorbic acid, important in the synthesis of collagen, the framework protein
for tissues of the body. Deficiency leads to scurvy, characterized by fragile
capillaries, poor wound healing, and bone deformity in children.
Vitamin D: A
steroid vitamin which promotes absorption and metabolism of calcium and
phosphorus. Under normal conditions of sunlight exposure, no dietary
supplementation is necessary because sunlight promotes adequate vitamin D
synthesis in the skin. Deficiency can lead to osteomalacia in adults and bone
deformity (rickets) in children.
Vitamin E:
Deficiency can lead to anemia.
Vitamin K: An
essential factor in the formation of blood clotting factors. Deficiency can
lead to abnormal bleeding.
Nutritions:
For the treatment
of nutritional disease, any of the nutrient-related diseases and conditions
that cause illness in humans. They may include deficiencies or excesses in the
diet, obesity and eating disorders, and chronic diseases such as cardiovascular
disease, hypertension, cancer, and diabetes mellitus. Nutritional diseases also
include developmental abnormalities that can be prevented by diet, hereditary
metabolic disorders that respond to dietary treatment, the interaction of foods
and nutrients with drugs, food allergies and intolerances, and potential
hazards in the food supply. All of these categories are described in this
article. For a discussion of essential nutrients, dietary recommendations, and
human nutritional needs and concerns throughout the life cycle, see nutrition,
human.

1. Add acid method. After the raw materials were crushed, they were placed in a stirrer, and formic acid was added at a concentration of 85%, and the amount was 3.5% of the weight of the raw materials, while stirring. The pH of the raw material after acidification should be less than 4. Put the acidified raw material into an acid-resistant liquefaction tank for liquefaction. Generally, the liquefaction time is 1 to 2 days at 30 to 35°C, and 7 to 8 days at room temperature below 15°C. If the fat content in the raw material is high, the liquefied product is preferably degreased again, which can improve the product quality and extend the product storage period. The commonly used degreasing method is that the liquefied product is heated up to 60° C., and the oil is decentrifuged by a centrifuge to obtain a defatted liquid fish feed. The degreased liquefied material is stored in an acid-resistant covered container and can be stored at room temperature for 1 to 2 years.
2. Molasses fermentation method. Molasses is a waste of cane sugar. After the raw material is crushed, molasses is added; the amount is 15% of the weight of the raw material, and the mixture is uniformly stirred into a sealed container, and natural anaerobic fermentation is performed at 25 to 30%. Since molasses contains natural lactic acid bacteria, lactic acid bacteria will multiply as anaerobic fermentation progresses, and a large amount of lactic acid will be secreted, which will rapidly lower the pH of the mixture to less than 5, and some bacteriostatic and bacteriostatic substances will be produced during the growth of lactic acid bacteria. , Play anti-corrosion effect.
Clever liquefied fish feed
Liquefied fish feed is a kind of liquid feed produced by using low-value aquatic products and other animal wastes, adding a certain amount of acid or microbe to ferment after mincing, and producing autolysis through special enzymes carried by aquatic products. . The feed is acidic, resistant to storage, it is also known as acid storage. Processing liquefied feeds are generally supplemented with acid and molasses fermentation. The specific techniques are as follows:
