Internet-based frozen food online monitoring method

Abstract

The invention discloses an online monitoring method for frozen food based on the Internet, which uses a magnetic memory detection method to detect defects in the frozen food, including thawing status, color and smell changes; realizes quantification of defects through calculation formulas; and uses magnetic memory for detection Results The thawing status evaluation, color evaluation, and odor change evaluation of the frozen food were carried out; the technical index of the maximum safety score that the frozen food can withstand was obtained; the fuzzy comprehensive evaluation system was adopted, the quantitative and qualitative analysis were combined, and the evaluation was established in combination with the actual project Set up a comprehensive evaluation judgment matrix. The present invention is conducive to convenient monitoring and improved intelligence; the present invention has stricter control over the quality of food and reduces the influence of human subjective factors; the pass rate of products leaving the factory is higher, and indirectly promotes the good reputation image of the manufacturer.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an online monitoring method for frozen food based on the Internet. Background technique [0002] With the development of science and technology, electronic vision, electronic nose and electronic tongue have appeared, and have been more and more widely used in agricultural products, food testing and environmental monitoring. The so-called electronic vision is to use the image sensor to obtain the image information of the object, and then convert it into a digital signal, which is recognized and analyzed by the computer. Grading, even the freshness and maturity detection of meat, citrus and poultry eggs. [0003] With the improvement of the quality of life, people pay more and more attention to healthy diet.

Problems solved by technology

[0003] With the improvement of the quality of life, people pay more and more attention to healthy diet. Food manufacturers continue to improve the quality of food in order to accumulate users; , still needs manual separation on the assembly line; not only reduces production efficiency, but also human subjective factors lead to misjudgment, so that spoiled food flows into the market through inspection, which has a great impact on the manufacturer's image and sales

[0004] To sum up, the problems in the existing technology are: the accuracy of online monitoring of frozen food is not enough; and the degree of intelligence of the existing technology makes it inconvenient to use;
