Title: Processing of livestock industry by-product
Inventor: TANOKURA TADAYUKI
IPC: A23J1/10
Filed: 1989-07-04
Abstract: PURPOSE:To improve the yield of oil and obtain a water-soluble low-molecular protein from the major part of protein in the raw material by adding a proteinase to a finely chopped livestock industry by product without adjusting the pH of the by-product and separating the obtained protein decomposition products. CONSTITUTION:Proteinase is added to finely chopped livestock industry by-product without adjusting the pH of the by-product with an acid or alkali. A water-soluble low-molecilar protein can be produced by this process in high yield. The obtained slurry decomposition product is separated into solid and liquid e.g. by centrifugal separation. The solid component left after removing the major part of proteins and oils and fats is thermally sterilized at a high temperature. The thermal energy can be saved by this procedure. Separately, the oil layer in the liquid is separated from the water-soluble protein layer by sucking, etc., to recover the most part of the oils and fats in the raw material. An aseptic water-soluble protein can be produced by removing harmful microorganisms by a filter membrane from an aqueous solution of a protein layer containing minor components such as minerals and vitamins. The obtained protein product has good quality and excellent absorptivity and digestibility and is highly resistant to thermal deterioration because the product can be produced without using thermal sterilization process in contrast with the conventional process.
