Problems solved by technology

At present, the technical solutions described in the literature can be used to change the content of AGEs in processed foods at high temperatures such as 70-100°C. It is difficult to achieve a wide range of color changes at low temperature and normal temperature such as 0-25°C, and it is difficult to achieve long-term color changes. Such as the obvious color change in 10 days, so the above technical solution cannot be applied to low temperature environment detection

Abstract

The invention discloses a preparation method and application of a time-temperature indicator for monitoring temperature and freshness changes in mackerel transportation. The preparation method comprises the following steps: preparation of a Tris-Hcl buffer solution: dissolving tris (hydroxymethyl) aminomethane in water, then adjusting the pH value with hydrochloric acid to form the Tris-Hcl buffer solution, wherein the concentration of the Tris-Hcl buffer solution is 0.05-0.4 mol / l, and the pH value is 7.0. According to the invention, the technical problem of how to monitor the freshness of the prepared time temperature indicator in the cold-chain transportation process by obtaining wide color change and continuously realizing color change for a long time in the range of 0-25 DEG C can be solved.

Description

technical field [0001] The invention belongs to the field of food monitoring, and in particular relates to a preparation method of a time-temperature indicator based on Maillard reaction. The time-temperature indicator prepared by the method can be used to monitor the freshness of aquatic products during cold chain transportation. The present invention also relates to the application of the time and temperature indicator. Background technique [0002] The freshness of aquatic products is related to many factors, such as enzymatic reactions, chemical reactions, microbial contamination, loading and unloading processes, etc., and most of these factors are related to temperature changes. Therefore, temperature is considered to be the most critical factor affecting the quality and safety of aquatic products one. With the development of economic globalization, aquatic products can be transported to consumers through long-distance transportation. In the process of cold chain tran...
