Embodiment

[0042] This example provides a method for evaluating beef quality based on near-infrared spectral information. In order to realize the beef quality prediction by means of near-infrared technology, the present invention uses a domestic portable near-infrared spectrometer, selects the outer loin and small cucumber strips commonly used in barbecue beef as raw materials, and collects raw materials in the state of meat pieces and minced meat under the factory operating environment Based on the near-infrared data of beef, a fast and pollution-free prediction model for the quality of raw beef for barbecue was established, and the ability of near-infrared spectroscopy technology to predict the quality indicators of raw beef for barbecue was explored.

Abstract

The invention relates to the technical field of meat product quality inspection, in particular to a method for establishing a data model using a near-infrared spectrum information system to evaluate beef quality, and application of the method in evaluation of beef quality. The method comprises the following steps of (1) establishing large sample data of beef near-infrared spectrum, and inspecting related parameters of the beef quality; (2) according to the corresponding relationship of the large sample data of near-infrared spectrum and the related parameters of the beef quality, establishing a near-infrared spectrum data model, wherein the related parameters of the beef quality include main chemical component indexes and / or quality indexes; the main chemical component indexes comprise one or multiple of protein content, fat content and water content; the quality indexes comprise one or multiple of shear force value, cooking loss rate, water-retaining capability, and color differences L*, a* and b*.

Description

technical field [0001] The invention relates to the technical field of meat product quality detection, in particular to a method and application for establishing a beef quality data model using near-infrared spectral information. Background technique [0002] With the acceleration of the pace of life in modern society and the continuous integration of Chinese and Western food cultures, beef is becoming more and more popular among young consumers due to its unique flavor, nutritional properties and unique processing and cooking methods (such as frying, roasting, etc.). [0003] Raw materials are one of the main factors affecting the consumption value of beef. The beef processed and cooked by different parts and different qualities of raw materials often has great differences, especially in the Chinese market. Quality raw materials put forward higher requirements for beef quality evaluation and grading. Traditional beef quality testing and grading focuses on carcass evaluatio...
