In order to increase the taste of food, some businesses add illegal food additives to food, or add excessive additives, which seriously affects food safety
[0004] When food is produced, it must be inspected by the government department for the composition of food additives. The existing inspection technology uses high-performance liquid chromatography, ultraviolet analyzer, spectrophotometer, etc. for detection. The detection of these precision instruments is very accurate and easy to use. It is also easy to operate after proficiency, but the pretreatment of food before testing is cumbersome, especially solid food, which needs to be crushed first and then the ingredients in it are mixed into the solvent before testing. Solid food pretreatment device and supporting method

Abstract
The invention belongs to the technical field of food detection, and specifically discloses a food additive detection method and device. The method includes the following steps: 1, using the food additive detection device to crush solid food into 250-300 meshes, adding deionized water in the solid food, and performing centrifugal stirring processing on the solid food; 2, taking out an aqueous solution part in the solid food, and drying out a slide part; 3, using an ultraviolet-visible spectrophotometer to perform spectrum scanning on the aqueous solution part; 4, adding benzene into the solid part, performing centrifugal stirring on the solid part, taking out a benzene solution part, and drying out the solid part; 5, using a high-performance liquid chromatograph to perform detection on thebenzene solution part; and 6, adding ethanol into the solid part, performing centrifugal stirring, taking out an ethanol solution part, and using the high-performance liquid chromatograph to perform detection on the ethanol solution part. The purpose is to provide the food additive detection method and device which can conveniently and simply process the solid food.
Description
technical field [0001] The invention belongs to the technical field of food detection, and specifically discloses a food additive detection method and device. Background technique [0002] Food additives are synthetic or natural substances added to food for the purpose of improving food color, aroma, taste and other qualities, as well as for the needs of antisepsis and processing technology. At present, there are 23 categories and more than 2,000 varieties of food additives in my country, including acidity regulators, anticaking agents, defoaming agents, antioxidants, bleaching agents, leavening agents, colorants, color retaining agents, enzyme preparations, and flavor enhancers. , nutritional enhancers, preservatives, sweeteners, thickeners, spices, etc. [0003] In recent years, various additives in food, especially Sudan red, melamine, acesulfame potassium, etc., have been paid more and more attention by people. In order to increase the taste of food, some businesses add...
