Method for preparing eatable phycobiliprotein in laver

Abstract

The invention discloses a method for preparing eatable phycobiliprotein in laver, and belongs to the technical field of food processing. The method for preparing the phycobiliprotein comprises the following main processes: grinding the laver into powder, adding buffer solution into the powder, then adding cellulase and pectase into the solution to hydrolyze the solution, homogenizing the solution after enzyme inactivation, centrifugalizing the homogenized solution and taking supernatant, adding ammonium sulfate into the supernatant, reserving a salted-out substance between 25 and 60 percent ammonium sulfate saturation levels, desalting the salted-out substance by adopting ultra-filtration, and freeze-drying the desalted substance to obtain the phycobiliprotein (comprising phycocyanin and phycoerythrin). The phycobiliprotein prepared by the method can be used as a functional component and added into food and nutriment. The method for extracting the phycobiliprotein from the laver has the advantages that the raw materials are easily obtained, the method is simple and convenient, the extraction efficiency is high, and the like.

Description

technical field

[0001] The invention discloses a method for preparing edible-grade phycobiliprotein in laver, which belongs to the technical field of food processing. Background technique

[0002] Laver (Porphyra) has been paid attention to because of its high nutritional value and important health functions. Porphyra contains about 30% protein, most of which are phycobiliproteins.

[0003] At present, the application of phycobiliprotein in medicine, food and other industries has attracted widespread attention, and high-purity phycobiliprotein has been used in the pharmaceutical industry. However, at present, the extraction and development of phycobiliproteins are mainly extracted from algae such as Spirulina. The raw materials are expensive, the extraction cost is high, the purity is low, the subsequent purification process is complicated, and industrial production cannot be carried out. There has been no phycobiliprotein products on the market. Appear. The patent cost of...
