Problems solved by technology

At present, the domestic utilization rate of low-value marine fish and aquatic product processing waste is not high. It is mainly used in the extraction of protein hydrolyzate, and the waste residue after extraction is treated as garbage.
At present, the bone meal products on the market are mainly derived from the bones of land animals, with few sources of raw materials, and the ratio of calcium and phosphorus in bone meal is not suitable for human digestion and absorption.

Abstract

The present invention relates to a preparation process for novel bone meal. According to the process, marine fishing trash fishes are subjected to enzymolysis to obtain an activity peptide; the resulting enzymolysis waste from the enzymolysis reaction is adopted as a raw material, and is cleaned until the filtrate is clarified and does not contain water-soluble impurities, and then a drying treatment is performed; a screening treatment is performed to obtain a raw material fish bone; and the raw material fish bone is subjected to treatments of fat removing, impurity protein removing, collagen protein removing, filtering, deodorization, drying, crushing and the like. The preparation process of the present invention has characteristics of easily available raw materials, reasonable process design, strong operability, and controllable quality. With the preparation process, a high pressure hot water extraction method is adopted to remove collagen protein in the raw materials; the prepared bone meal has advantages of high purity, low loss rate, low processing cost and the like; and the ordinary hot water extraction method is optimized, disadvantages of long collagen protein removing time, low removal rate, and high energy consumption are overcome, and finally the bone meal preparation process applicable for industry production is determined so as to prepare the food grade and feed grade bone meal with the high added value.

Description

technical field [0001] The invention relates to a preparation process for food or feed raw materials, in particular to a novel bone powder preparation process. Background technique [0002] Studies have shown that the ratio of calcium to phosphorus in fish bones is relatively close to that of the human body, and the absorption rate of calcium and phosphorus is relatively high. It has been recognized by domestic and foreign nutrition experts as one of the most effective ways of calcium supplementation. At present, the domestic utilization rate of low-value marine fish and aquatic product processing waste is not high. It is mainly used in the extraction of protein hydrolyzate, and the waste residue after extraction is treated as garbage. However, the bone meal products currently on the market are mainly derived from the bones of terrestrial animals, with few sources of raw materials, and the ratio of calcium and phosphorus in bone meal is not suitable for human digestion and ...
