A method for producing an additive capable of improving the function of a feed for aquaculture

摘要

The present invention is an animal protein source of high-quality krill and enzymatically decomposes an animal peptide and a plant protein source of soybean meal by anaerobic fermentation of a peptide (peptide) -derived vegetable peptide with a bioactive substance, nucleic acid, which has excellent antioxidant power and a high amount of feeding. It is to provide an additive manufacturing method capable of improving the function of a blended feed composed of protein by adding a stevia material to increase in an appropriate ratio. To this end, the main raw material preparation process of preparing each of the main raw materials, paste-type krill peptide and powder-type soybean peptide; A stirring process of stirring and mixing the main raw material; A drying process of drying the stirred main raw material at a constant temperature; A crushing process of pulverizing the dried main raw material; And, the addition process of adding and mixing the secondary raw material containing nucleic acid and stevia to the pulverized main raw material; comprises, wherein the preparatory step of preparing a krill peptide during the main raw material preparation process is to keep the krill frozen at minus 18 ° C or lower. Krill preparation step to be performed, wet crushing step of crushing the frozen stored krill and then crushing it with a wet grinder, extracting and decomposing step to liquefy the crushed krill for a certain period of time under a certain temperature condition, and the liquefied krill Separation and de-separation step of separating the shell by centrifugation, pH adjustment step to improve the stability by controlling the hydrogen ion concentration of the liquefied krill from which the shell is separated, deactivation of the enzyme added in the extraction and decomposition step to deteriorate the liquefied krill. Inactivation step to prevent, centrifuging the liquefied krill after the deactivation step to oil Centrifugation step of separating the liquid krill peptide, filtering step of removing the foreign substance by filtering the liquid krill peptide separated from the oil, and vacuum concentration the moisture content of the liquid krill peptide from which the foreign substance has been removed below a certain value to form a paste It characterized in that it comprises a concentration step, and a sterilization step of pasteurizing the krill peptide in the paste form.
