Problems solved by technology

However, during the storage and processing of Penaeus vannamei, the muscle will still undergo freezing denaturation, resulting in a decline in quality and affecting the quality of subsequent processed products.
At present, the research mainly focuses on the changes of the physical and chemical properties of shrimp meat during the frozen storage process, but there are very few studies on the application of Raman spectroscopy for quality detection.

Embodiment 1

[0016] The present invention includes cleaning, shelling, cryopreservation, freeze-drying of shrimp, Raman spectrum measurement, data processing and other procedures of shrimp, and the specific production process is as follows:

[0017] (1) Shrimp cleaning and shelling: Wash and drain a batch of Penaeus vannamei shrimp with a mass of about 0.5KG, cut off the head, and peel off the shell from the tail;

[0018] (2) Cryopreservation: slice transversely (about 2mm) at the penultimate sarcomere of the tail of Penaeus vannamei, sample each prawn separately, store them at -10°C, and store each group for 2 weeks;

[0019] (3) Freeze-drying of shrimp: Store the sliced ​​shrimp meat for a certain period of time as required, take it out, put it in a -80°C refrigerator for 2-3 hours, and dry it with a vacuum freeze dryer for 24 hours before testing;

[0020] (4) Raman spectrum measurement: NicoletAlmegaXR laser confocal Raman microscope, power 5mW, exposure time 10s, acquisition times 10...

Abstract

The invention discloses a Raman non-destructive testing method for the quality of frozen Penaeus vannamei, and relates to the technical field of aquatic product quality testing. According to the changes in the properties of Penaeus vannamei during frozen storage, Raman spectroscopy was used to quantitatively analyze the change rule of the secondary structure of shrimp meat, and the effects of frozen storage temperature and time on the change of shrimp meat secondary structure were studied. Structural evaluation of the quality of frozen Penaeus vannamei, this method can realize the non-destructive evaluation of the quality of frozen Penaeus vannamei.

Description

technical field [0001] The invention relates to the technical field of quality detection of aquatic products, in particular to a nondestructive detection technology for quality changes of Penaeus vannamei during freezing. Background technique [0002] The meat of Penaeus vannamei is soft, easy to digest, rich in nutrition, and has many therapeutic effects, so it is favored by consumers. However, during the storage and processing of Penaeus vannamei, the muscle will still undergo freezing denaturation, resulting in a decline in quality and affecting the quality of subsequent processed products. At present, the research mainly focuses on the changes of physical and chemical properties of shrimp meat during frozen storage, but there are very few studies on the application of Raman spectroscopy for quality detection. The present invention will use the advanced technology of Raman spectroscopy to cut in from the perspective of the change of the microscopic molecular structure of...
