Problems solved by technology

[0003] The price of four-cornered clams is far from that of Meretrix meretrix, but its rich nutritional value is not lower than that of Meretrix meretrix
[0004] In recent years, with the general improvement of people's quality of life, more and more attention has been paid to the nutritional value of food. Seafood, especially shellfish, is popular. However, a lot of waste is formed during the deep processing of clams. Huge waste of biological resources, and easy to pollute the environment

Embodiment 1

[0025] The raw material Sijiao clam processing waste (the mixture of the Sijiao clam processing waste water and the remaining mantle, viscera and other soft substances on the inner surface of the shell, wherein the dry matter weight content is 15%) is put into the enzymatic hydrolysis tank for heating and sterilization ( 100°C, 15 minutes), add papain (the amount of enzyme added is 700u / g raw material) for mixing, adjust the pH to 7.2 with NaOH solution (please specify the concentration range), enzymolysis at 56°C for 7 hours, and heat the hydrolyzate at 85°C Inactivate the enzyme for 15 minutes, then add Flavourzyme endopeptidase and telopeptidase (the total enzyme addition amount of the two is 300u / g raw material, and the ratio of endopeptidase and telopeptidase is 1: 1) to mix, and use NaOH solution ( Please clarify the concentration range) Adjust the pH to 6.4, and continue the enzymatic hydrolysis at 50°C for 4 hours. Finally, raise the temperature of the enzymatic hydrol...

Embodiment 2

[0028] Put the waste from raw clam processing (wastewater from clam processing and soft substances such as mantle and viscera on the inner surface of the shell, wherein the dry matter weight content is 12%) into an enzymatic tank for heating and sterilization (100°C , 20 minutes), add papain (the amount of enzyme added is 700u / g raw material) for mixing, use NaOH solution (please specify the concentration range) to adjust the pH to 7.5, enzymolysis at 60°C for 5 hours, and heat the hydrolyzate for 80 Inactivate the enzyme at ℃ for 20 minutes, then add Flavourzyme endopeptidase and telopeptidase (the total enzyme addition amount of the two is 300u / g raw material, the ratio of endopeptidase and telopeptidase is 1:1) to mix, and use NaOH solution (Please specify the concentration range) Adjust the pH to 6.6 and continue the enzymatic hydrolysis for 5 hours at a temperature of 55°C. Finally, heat up the enzymolysis solution to 85°C to inactivate the enzyme for 15 minutes.

Abstract

The invention relates to a method for producing feed additives by subsection enzymatic hydrolysis of four-cornered clam processing waste. The feed additives prepared by the invention contain rich amino acids, and when added to aquaculture feed, they have better food-attracting effects and growth-promoting effects. effect.

Description

technical field [0001] The invention belongs to the enzymatic production process of marine bioengineering, in particular to a process for producing feed additives by enzymatically enzymolyzing four-cornered clam processing waste in sections. Background technique [0002] The square clam (Mactra Veneriforznis) belongs to the clam branch class, the clam family, commonly known as the white clam, and mostly lives in the middle and lower areas of the intertidal zone and shallow sea mud beaches (5-10cm). April is the peak breeding season, and the shell length of 2-3 weeks old can reach 3cm. Four-cornered clams are widely distributed in Jiangsu Province, mainly in coastal cities such as Nantong and Lianyungang. [0003] The price of four-cornered clams is far from that of Meretrix meretrix, but its rich nutritional value is not lower than that of Meretrix meretrix. Every 100 grams of fresh clam meat contains 11.8g of protein, 0.6g of fat, 6.2g of carbohydrates, 2.4g of inorganic ...
