Abstract

A regent can detect fresh degree of royal jelly, which is composed of 10-40%HCl, 0-20% NaCl, 0-10%C4H4N2O3, 0-20%FDNB and water. Mix royal jelly with regent at a mass-volume ratio of 1:3-1:20 and estimate fresh degree of royal jelly based on the intermixture color. The regent can generate coloration reaction with royal jelly and the color appears difference according to different saving temperature and time in a period of time, which can detect fresh degree of royal jelly quickly. The regent has rational design and convenient operation, needs simple apparatus, is suitable for field detecting, has short time consuming, can detect fresh degree quickly, has high detecting sensitivity, can reflect influence of royal jelly saving process on its fresh degree, perfects current quality standard of royal jelly, detects quality effectively and regulates the market.

Description

technical field

[0001] The invention relates to a reagent for rapidly detecting the freshness of royal jelly, in particular to a reagent for rapidly determining the storage temperature and storage time experienced by the royal jelly. Background technique

[0002] Royal jelly is a key substance that affects the differentiation of honey bees, and is of great significance to the nutrition and development of queen bees. Fresh royal jelly is rich in biologically active substances, which have high nutritional and health effects on the human body, such as enhancing immunity, anti-fatigue, anti-aging, anti-tumor, and improving sleep. Because some active ingredients in royal jelly are sensitive to temperature, royal jelly has high requirements on storage conditions. If the storage temperature is too high or the storage time is too long, its physical properties, chemical composition and quality will change significantly. At the same time, feeding experiments showed that the freshness...
