Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food detection, in particular to a food detection device for food production. BACKGROUND

[0002] Food is defined as all kinds of finished products, raw materials and traditional food and medicine homologous substances for human consumption or drinking at the regulatory and scientific level, but does not cover items for treatment. The production of food needs to go through many links, among which food detection is an essential key technology to ensure food quality and safety. The core is to systematically test the materials covering raw materials, auxiliary materials, semi-finished products, finished products and by-products according to international, national and industry food safety standards to evaluate the compliance of various quality and hygiene indicators. Through production detection, potential problems can be found and corrected in time, so as to ensure the excellent quality and safety of food in the whole production process.

[0003] Sample pretreatment is the first step of food detection, and its success or failure directly determines the accuracy of the detection result. This process usually involves crushing or homogenizing the sample, and then using a suitable solvent to extract the target analyte, so that it can be efficiently transferred from the complex matrix to the solvent. However, there is an inherent technical challenge in the mechanical crushing process: under the action of high-intensity mechanical shearing and friction, significant local temperature rise effect will occur in the crushing cavity. This thermal effect can easily cause the degradation, transformation or volatilization of heat-sensitive components in the sample matrix, thereby seriously affecting the accuracy and reliability of the subsequent detection results. Taking vitamin substances (such as vitamin C and B vitamins) as an example, as typical heat-sensitive nutrients, their molecular structure is easily destroyed by high temperature under improper crushing conditions, resulting in a serious underestimate of their content determination value, which not only causes the deviation of product nutritional value evaluation, but also cannot truly reflect the original quality of the product.

[0004] In order to avoid the thermal effect generated by the traditional sample detection pretreatment method, the development and application of an efficient low-temperature treatment device will significantly improve the reliability and accuracy of food detection results, providing accurate sample information feedback for food production process development and optimization, product quality control, nutrition labeling, etc. and ensuring product compliance.
