Smartphone-based non-destructive detection method for internal eating quality of Chinese mitten crab

Abstract

The invention belongs to the technical field of non-destructive testing, and relates to a method for non-destructive testing of the internal eating quality of Chinese mitten crabs based on smart phones; the steps are: taking Chinese mitten crabs of different mature stages as samples, and using a smart phone-based spectral data collection system to collect the samples Spectral data of crab meat, hepatopancreas, female crab gonad, and male crab gonad ROI, and determine the content of characteristic chemical substances; preprocess the spectral data with SG smoothing filter; combine crab meat, hepatopancreas, The content of characteristic chemical substances in the gonads of female crabs and gonads of male crabs is used to formulate the internal edible quality grading index of Chinese mitten crabs; the pre-processed spectral data and the data of characteristic chemical substance content are one-to-one, and the characteristic wavelengths corresponding to each part of the sample are obtained through algorithms; A predictive model is constructed with characteristic wavelength data and edible quality grading indicators; the invention has the advantages of accuracy, high efficiency, non-destructive and real-time, and makes up for the vacancy of internal edible quality grading standards of commercial crabs.

Description

technical field [0001] The invention belongs to the technical field of non-destructive testing of aquatic products, and in particular relates to a non-destructive testing method for the internal eating quality of Chinese mitten crabs based on a smart phone. Background technique [0002] Chinese mitten crab, also known as hairy crab, is an important and valuable aquatic product in my country. It is delicious, nutritious, rich in protein, vitamins and various trace elements, and is deeply loved by consumers. The edible parts of hairy crabs are crab meat, hepatopancreas and gonads. Compared with the weight and size of commercial crabs, consumers pay more attention to the maturity and flavor of the edible parts. Therefore, crab meat flavor, hepatopancreas maturity and gonad maturity are the key factors to determine the internal eating quality of Chinese mitten crab. The classification of traditional commercial crabs mainly relies on external quality indicators such as weight an...

Problems solved by technology

[0005] In order to overcome the deficiency that the traditional commercial crab grading method cannot realize the rapid and non-destructive detection of its internal edible quality, the present invention provides a method for detecting the internal edible quality of Chinese mitten crabs using portable near-infrared spectroscopy technology based on smart phones, so as to realize the internal edible quality of commercial crabs. Rapid and non-destructive identification of quality
