Abstract

The invention discloses a group of polypeptide markers for evaluating the quality of live oysters. The sequence of the polypeptide is: SEQ ID NO.1: SSSTGEVGTYSGTTN; SEQ ID NO.2: TARNEANVNI; SEQ ID NO.3: VGIIKGSSSEEA; SEQ ID NO.4: TARNEANVNIY. For the first time, the present invention uses peptidomics technology to comprehensively study the endogenous peptides of oysters of different qualities, and obtains a set of polypeptide markers that can be used to evaluate the quality of live oysters. The multiple reaction monitoring analysis method established by stage mass spectrometry verifies the correctness of the marker peptide sequence and the applicability for routine liquid mass analysis. It can supplement the mechanism of quality change of live oysters and improve the evaluation system of quality change in the process of keeping alive.

Description

technical field

[0001] The invention belongs to the field of food science, and in particular relates to a group of polypeptide markers for evaluating the quality change of live oysters. Background technique

[0002] Oyster is an important marine aquatic resource. It is rich in nutrition and fresh and tender, and is deeply loved by consumers. With the changes in the product structure of shellfish seafood in the world, fresh and live oysters are the most popular in domestic and foreign markets, especially with the improvement of people's consumption level, the demand for fresh and live shellfish in some inland areas is also increasing high. Therefore, we need to optimize the fresh supply chain of live oysters. The premise of improving the live oyster supply chain is to establish an accurate quality evaluation method for live oysters. However, due to the complexity of changes in living organisms, there is still a lack of reliable quality evaluation methods for live oysters, ...
