The production technology. Ergamin is a highly purified mixture of 18 free amino acids in proportion close to egg albumin, adopted by nutritionists as a protein standard. Meat and poultry production waste containing keratin protein are used as raw materials. These are horned flour (97% keratin), pork bristles (75% keratin), feather flour (72% keratin). The production method of a supplement complex includes: acid hydrolysis of keratin; sorption on anionite (anion exchange resin), clarification of the resulting solution of amino acids; elution of amino acids from cation exchanger; sterilizing ultrafiltration of an amino acid solution and spray or freeze drying of the drug. The resulting product is a white, loose, slightly hygroscopic odorless powder with a weak mushroom taste, well soluble in water. The powder is easily encapsulated. L-lysine production technology is similar. Feed L-lysine is used as raw materials. Collagenit technology is identical to Ergamin. Raw material for Collagenit is a split of cattle hides. No additives such as magnesium stearate, silicon dioxide, etc., are use in production.
