Abstract

The invention discloses a method for rapidly detecting storage quality of aseptically packaged sea cucumber protein peptide powder based on DVS and GC-IMS technologies. The sea cucumber protein peptide powder is used as the raw material, and the DVS (dynamic vapor absorption method) and GC-IMS (gas chromatography-ionic migration spectrometry) are comprehensively used for detecting and identifying.A moisture absorption kinetic curve and a moisture absorption isotherm of the sea cucumber protein peptide powder can be acquired through a DVS system, and the volatile substances are separated through the GC-IMS, the sea cucumber protein peptide powder after the separation of the volatile substances is finished enters an IMS unit to be measured twice, thereby successfully constructing a flavor fingerprint of the sea cucumber protein peptide powder. Through the method disclosed by the invention, the sea cucumber protein peptide powder packaged and stored under different conditions can be distinguished; the method can be applied to the quality grading and shelf life research of the sea cucumber protein peptide powder, has the features of being significant, less in raw material consumption,simple in operation, rapid in detection speed and high in accuracy.

Description

technical field

[0001] The invention relates to the technical field of flavor chemical analysis, in particular to a method for rapidly detecting the storage quality of aseptically packaged sea cucumber protein peptide powder based on DVS and GC-IMS technologies. Background technique

[0002] "Compendium of Materia Medica Supplements" once recorded: Sea cucumber (sea cucumber) is sweet and salty, nourishing the kidney, benefiting the essence, urinating, aphrodisiac and treating impotence. One of them is not only a precious food, but also a high-quality medicinal material. There are more than 140 kinds of sea cucumbers in China, of which there are more than 20 kinds of edible sea cucumbers. Sea cucumbers contain a lot of protein and a variety of trace elements that are beneficial to the human body. It is a high-quality nutritious food that does not contain cholesterol. With the deepening of research and the popularization of peptide knowledge, peptide products will be recogniz...
