Abstract
Description
technical field
[0001] The present invention relates to the technical field of on-site rapid high-throughput food additive detection, more specifically to the preparation of a quantum dot molecularly imprinted microsphere quartz fluorescent sensor for detecting trace food additives. The present invention also relates to the use of the quantum dot molecule Method for on-site detection of trace food additives in food, wine and beverage samples by imprinted microsphere quartz fluorescent sensor. Background technique
[0002] Food additives mainly include antioxidants, colorants, color protectants, flavor enhancers, preservatives, sweeteners, emulsifiers, thickeners, etc. according to the different uses of the additives. These food additives, which are permitted by regulations and considered safe, do not guarantee absolute safety in fact, and may cause physical and health damage to some people under certain conditions. For example, aspartame is considered the ideal sweetener fo...
