Embodiment

[0031] Such as figure 1 Shown, the pork product of the present embodiment carries out the method for rapid moisture detection, specifically as follows:

[0032] Purchasing 20 untreated pig dorsal muscles and 20 hind legs from the pig slaughterhouse of Xinzao Branch of Guangzhou Panyu Food Group Co., Ltd., cut them into 2cm thick slices with a meat cutter. Take 150 pieces as raw materials. The raw materials were randomly divided into 6 groups and numbered, 30 pieces in each group. Group 1 is hot fresh meat, and the samples are not processed; Group 2 is refrigerated meat, and the samples are stored in a refrigerator at 4°C for 24 hours, taken out and left at room temperature for 4 hours; Group 3 is frozen and thawed meat, and the samples are randomly divided into 2 parts 15 pieces per batch, stored in -6°C and -18°C refrigerators for 24 hours, taken out and left at room temperature for 4 hours; Group 4 was cured meat, the samples were randomly divided into 5 portions of 6 piec...

Abstract

The invention discloses a rapid pork product moisture content detection method. The method includes 1, acquiring hyperspectral reflectance images of pork samples; 2, calculating the moisture content of the pork samples by the direct drying method of national standard GB / 50093-2010; 3, extracting feature wavelength of the pork samples; 4, considering the moisture content X of the pork samples, and establishing a multiple linear regression mathematical model on the basis of a spectral reflectance value of the feature wavelength of the pork samples; 5, predicting the moisture content of the pork samples to be detected. The method has the advantages of high detecting accuracy, respective model establishment of single samples is omitted, and the general applicability is provided.

Description

technical field [0001] The invention relates to the field of non-destructive detection of meat quality, in particular to a method for rapid moisture detection of pork products. Background technique [0002] Pork is rich in nutrition and delicious, and is one of the favorite meats of our people. my country is a big pork producer. According to the statistics of the National Bureau of Statistics, the total pork output in 2013 was 54.9303 million tons. As an important raw material, pork can be processed into a variety of products, such as: meatloaf, meatballs, cured meat, bacon, ham, etc. In the storage and transportation of pork, pork is often stored in a refrigerated or frozen manner. The moisture content of pork and its products is closely related to food quality and safety. If the moisture content is too high, it is easy to breed bacteria, mold and other microorganisms, and it is easy to spoil; if the moisture content is too low, the taste and nutrition of pork will decre...
