Abstract

A smallpeptide chelate trace element feed additive comprises, in mass percent, from 18 to 89% of smallpeptide protein, from 10 to 20% of salt and from 0.59 to 62% of inorganic trace element when in a dry state. A production process includes following steps of (1) concentrating protein hydrolysate waste liquor which has the solid content of 5-15% and is generated from production of chondroitin and heparin sodium into protein hydrolysate waste liquor with the solid content of 30-40%; (2) adding prepared single monomial or compounded inorganic trace element solution with the mass percent concentration of 15-35%, controlling a pH (potential of hydrogen) value to be 6-8, and performing chelation reaction; and (3) performing spraying drying at the temperature ranging from 180 DEG C to 220 DEG C. The smallpeptide chelate trace element feed additive and the production process thereof effectively avoid waste liquor pollution generated in a production process of the chondroitin and heparin sodium, and turn waste into wealth, and prepared organic chelate feed additive enables the additional value of the waste liquor to be maximized. Spraying drying technology is adopted for the production process, and the problem that drying time is long and products are easy to be polluted by bacteria in a common method is solved.

Description

technical field [0001] The invention relates to a feed additive and a production process thereof, in particular to a feed additive containing organic chelated trace elements and a production process thereof. Background technique [0002] As a new type of feed additive in the world, organic chelated trace elements have been marketed and developed rapidly. This product is more conducive to animal absorption and reduces the pollution caused by inorganic minerals. However, the old products mostly use a single amino acid to chelate minerals, or use vegetable protein (soybean meal) to hydrolyze to prepare chelated trace elements. Although animal hydrolyzed protein can also produce organic chelated products, due to cost problems, no very suitable products have come out. In the process of extracting chondroitin and heparin sodium by biochemical technology, a large amount of hydrolyzed protein waste liquid will be produced, and its COD value is very high. Direct discharge will caus...
