Problems solved by technology

[0004] The purpose of the present invention is to provide a process for extracting shrimp protein powder. The existing shrimp protein powder is extracted from shrimp meat stripped from the shell, which has the disadvantages of high production cost and high product price, and cannot satisfy the needs of the general population. The needs of the present invention are conducive to reducing product production costs and reducing product prices

Embodiment Construction

[0009] The present invention is further described in conjunction with the examples. In the present invention, shrimp processing waste is used as raw material, protein is extracted by enzymatic method, centrifugal spray drying and spray drying are used to obtain powdery shrimp protein powder. The specific process is to clean the fresh headed shrimp shells and transport them to the hopper of the extruder with a conveyor, rinse with water during the conveying process, extrude the shrimp meat and shrimp brains inside, and let the empty shells enter the carapace The element production line, the slurry flows into the atmospheric pressure enzymolysis kettle through the middle hole of the pressure wheel. The temperature of the slurry is raised to 45-55° C., preferably 50° C., and protease is added at a mass ratio of 100,000:1 to carry out enzymatic hydrolysis for 4 hours. Put the enzymatic solution while hot into the suction filter tank to filter to remove the granular solids inside. ...

Abstract

The invention relates to an extraction technology of shrimp albumen powder, belonging to the technical field of chemical industry. The extraction technology correspondingly changes the extraction technology of the shrimp albumen powder by changing raw materials for extracting the shrimp albumen powder. The extraction technology is mainly characterized by using fresh shrimp processing leftovers asraw materials, extracting albumen in shrimp shells by an enzyme process and obtaining powdery shrimp albumen powder by adopting filter liquor which is dried, hydrolyzed by enzyme and filtered by centrifugal spray. The extraction technology greatly lowers the price of the raw materials, can also lower the prices of products, sufficiently satisfy the requirements of great masses and be beneficial for using wastes, protecting the environment and reducing the production cost and the prices of the products.

Description

technical field [0001] The invention relates to a process for extracting shrimp protein powder, which belongs to the technical field of chemical industry. Background technique [0002] Shrimp protein powder has a high content of essential amino acids, accounting for 41.29% of the total amino acids. It can be used as a fortified nutritional food for infants, the elderly, pregnant women and special populations (frail patients), such as vitamins, minerals, soluble The fortification of nutrients such as cellulose will be applicable to a wider range of people; it can also be used as a condiment. [0003] The existing shrimp protein powder is extracted by adding protease from the shrimp meat that has peeled off the shell, and the high-quality protein contained in the shrimp meat is extracted and separated to make pure protein. The current shrimp protein powder is expensive because of raw materials. The production cost of the product is high, and the price of the product is also h...
