Nondestructive testing method for internal eating quality of Eriocheir sinensis based on smart phone

Abstract

The invention belongs to the technical field of nondestructive testing, and relates to a nondestructive testing method for the internal eating quality of Eriocheir sinensis based on a smart phone. The method comprises the following steps: taking Eriocheir sinensis in different mature periods as samples, acquiring spectral data of crab meat, hepatopancreas, female crab gonad and male crab gonad ROI of the samples by utilizing a spectral data acquisition system based on the smart phone, and measuring the contents of characteristic chemical substances of the samples; carrying out SG smooth filtering preprocessing on the spectral data; according to the maturity of the samples, combining with the characteristic chemical substance content of crab meat, hepatopancreas, female crab gonad and male crab sex to formulate the grading index of the internal eating quality of the Eriocheir sinensis; enabling the preprocessed spectral data to be in one-to-one correspondence with the characteristic chemical substance content data, and obtaining the characteristic wavelength corresponding to each part of the sample through an algorithm; constructing a prediction model according to the characteristic wavelength data and the edible quality grading indexes. The method has the advantages of accuracy, high efficiency, no damage and real-time performance, and makes up the vacancy of the grading standard of the internal edible quality of the 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
