The technology of production is as follows: Ergamine "is a highly purified mixture of 18 free amino acids in a ratio close to egg albumin, adopted by nutritionists as a protein standard. As raw materials used waste meat and poultry industry containing protein keratin. These are horned hoof flour (97% keratin), pork bristles (75% keratin), feather flour (72% keratin). A method for producing the complex includes acid hydrolysis of keratin; sorption on 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 product is easily encapsulated. L-lysine technology is similar. As raw materials, feed L-lysine is used. Collagenite technology is identical to Ergamine. As a raw material, a split of cattle hides is used. No additives such as magnesium stearate, silicon dioxide, etc., are added to the preparations.
