Embodiment 1

[0012] Weigh 10 kg of fresh shrimp, add 10 kg of water, crush and beat with a beater until the particle size of the solid particles is 60 mesh to 100 mesh. Add 2kg of peanut oil and 30g of compound protease Protamex to the beaten mixture, keep it warm at 45-55°C for 7h, and treat it with ultrasonic treatment for 10min every half hour during this period, the ultrasonic frequency is 25kHz, and the power is 30w. After the reaction is completed, centrifuge to break the emulsion, adopt 3000rpm, centrifuge for 20min, separate and take the upper oil phase to obtain product A.

Embodiment 2

[0014] Weigh 20 kg of the remaining shrimp heads and shells after peeling off the shrimp, add 25 kg of water, crush and beat with a beater until the particle size of the solid particles is 60 mesh to 100 mesh. Add 2kg of edible oil obtained by mixing sunflower oil and palm oil at a mass ratio of 1:1, then add 160g of complex protease Protamex, and keep it warm at 45-55°C for 6 hours. The power is 60w. Use salting-out to break the emulsion, add 1000g of common salt, stir at 100rpm for 10min, separate and take the upper oil phase to obtain product B.

Embodiment 3

[0016] Weigh 30 kg of fresh shrimp heads and shrimp shells, add 60 kg of water, crush and beat with a beater until the particle size of the solid particles is 60 mesh to 100 mesh. Add 5kg of soybean oil and 150g of composite protease Protamex to the beaten mixture, and incubate at 45-55°C for 5h. During this period, use ultrasonic treatment for 10min every half hour, with ultrasonic frequency of 25kHz and power of 30w. After the reaction is completed, centrifuge to break the emulsion, adopt 3000rpm, centrifuge for 20min, separate and take the upper oil phase to obtain product C.

Abstract

The invention discloses a method for extracting shrimp oil high in astaxanthin and high phospholipids from low-value shrimp aquatic products such as small shrimps, shrimp shells and shrimp heads. The method comprises the following steps: raw material processing-extraction-emulsification separation-preparation of shrimp oil powder. The shrimp oil extracted by the method is rich in both neutral astaxanthin and polar phospholipids, has simple operation, no pollution and no addition of chemicals in the process, and the product can be used in food, health food and biomedicine.

Description

technical field [0001] The invention belongs to the field of food science, and mainly relates to a method for extracting shrimp oil high in astaxanthin and high phospholipids from low-value shrimp aquatic products such as small shrimps, shrimp shells and shrimp heads. Background technique [0002] Shrimp is an arthropod that lives in water. It belongs to arthropod crustaceans. There are many types, including Antarctic red shrimp, green shrimp, river shrimp, grass shrimp, prawn, prawn, lobster, etc. Shrimp is rich in nutrition, and its meat is soft and easy to digest. It is an excellent food for people who are weak and need to take care of themselves after illness. Shrimp is rich in magnesium. Magnesium has an important regulating effect on heart activity and can protect the cardiovascular system. It can reduce blood cholesterol levels, prevent arteriosclerosis, and expand coronary arteries at the same time, which is beneficial to prevent high blood pressure. and myocardial ...
