Method for detecting freshness of meat based on intelligent mobile phone

Abstract

The invention discloses a method for detecting the freshness of meat based on an intelligent mobile phone. The method comprises the following steps: (1) calling a camera function of the intelligent mobile phone through an APP of the intelligent mobile phone, and selectively acquiring a certain area of full-color picture information of the section of a meat substance for multiple times; (2) reading values such as R, G and B of pixels in color pictures through the APP, culling the pixels where R+G+B is greater than or equal to 715 and R+G+B is less than or equal to 50 so as to remove black dots and high-white reflective pixel points from the pictures, and then statistically calculating a mean value of R, G and B of the rest of pixels in the pictures; (3) converting the values of R, G and B into an LAB color mode according to a formula of RGB-XYZ-LAB; (4) evaluating the quality of the meat according to values of L*, a* and b* of an LAB color space. According to the method disclosed by the invention, the freshness of the meat can be directly evaluated based on the APP technology of the intelligent mobile phone, and a result can be directly displayed in a display screen of the mobile phone; the method is quick, effective, simple and feasible.

Description

technical field [0001] The invention belongs to the field of food safety detection, and relates to the rapid detection of the freshness of meat substances based on a smart phone APP. Background technique [0002] China is the world's largest meat exporter and consumer. Generally, livestock have strict procedures and testing requirements from breeding and slaughtering, to circulation, slaughter, and finally to terminal sales. As slaughtered raw meat enters the circulation of food and non-staple food, slaughtering and processing companies pay more attention to the quality control of meat. Through the identification of the color of the slaughtered meat material by different meat colors, a clearer guideline for the selection of raw materials for meat products can be obtained. From the past to rely on human eyes to identify meat color, to relying on high-tech measurement results to identify, the control and research on meat quality is an important topic in the field of animal hu...
