Embodiment 1

[0031] (1) After washing the selected fresh sea urchin, use scissors to pry open the black soft shell with radial thorns, use a spoon to dig out the yellow sea urchin eggs in the shell that look like orange petals, remove the internal organs, weigh 2000g, add 12-16L of deionized water, refining, that is, the sea urchin yellow pulp, put the sea urchin yellow pulp in a 20L enzymatic hydrolysis tank, stir evenly, pass steam into the jacket to raise the temperature to 70-80°C, and maintain it for 10- 15min, then cool to 45±1°C, adjust the pH value to pH8~10;

[0032] (2) Add 20-40g of lipase (1×10 4 u / g), under stirring at 20-30rpm, hydrolyze at 45±1°C for 3-4 hours at a constant temperature. Its function is to hydrolyze the oil in sea urchin yellow into fatty acid and glycerin. into the water phase;

[0033] (3) After the enzymatic hydrolysis, the enzymatic hydrolysis solution was ultrafiltered with an ultrafiltration membrane with a molecular weight cut-off of 10,000 Da, the p...

Abstract

The invention discloses sea urchin peptide oral liquid and a preparation method thereof. The preparation method is characterized by comprising the following steps: after fresh sea urchins are stripped off, taking out sea urchin gonads, mixing the sea urchin gonads and water for grinding, adding lipase for enzymolysis degreasing, performing ultrafiltration to collect trapped fluid which is a sea urchin gonad coarse protein solution, performing periodical cooperative enzymolysis on the sea urchin gonad coarse protein solution by adopting bromelain and ginger protease, performing filtration and ultrafiltration on enzymatic hydrolysate, and mixing and concentrating to obtain the sea urchin peptide oral liquid. According to the method, the phenomenon of rancidity of the sea urchin gonad is effectively prevented; the utilization rate of sea urchin proteins is greatly increased, and the food safety is effectively guaranteed; furthermore, the taste of the sea urchin peptide oral liquid is improved, and due to the antioxidant activity, the stability of the sea urchin peptide oral liquid is greatly improved, and the expiration date is prolonged; furthermore, the sea urchin peptide oral liquid has auxiliary effects of adjusting immunity, protecting the liver, resisting tumors and aging on the sea urchin gonads.

Description

technical field [0001] The invention relates to the technical field of bioengineering, in particular to a sea urchin peptide oral liquid and a preparation method thereof. Background technique [0002] The name of sea urchin was first recorded in "Materia Medica", which is a marine aquatic product that is widely eaten all over the world. The gonad of sea urchin is sea urchin yellow, which contains a large amount of protein, amino acid, highly unsaturated fatty acid, sugar and some physiologically active substances. It not only has high food value, but also has excellent medicinal functions. Good control effect. China's Liaoning, Shandong, Guangdong, Fujian and Hainan have always had the habit of eating sea urchins. Japan, the Malay Archipelago, South America and some countries along the Mediterranean Sea, such as France, Italy, Greece and other countries also have the habit of eating sea urchins, especially the Japanese people are particularly fond of eating sea urchins.
