Abstract

The present invention relates to the determination method of the content of glycine, the composition and the component of the reagent using double amplification method, enzyme colorimetric method and enzyme-linked method technology, and the technical principle of its determination is based on hydrogen cyanide synthase, carbamoyl phosphate synthesis The series of catalyzed reactions of the enzyme and glyceraldehyde-3-phosphate dehydrogenase are completed, and the invention also relates to a glycine determination kit. The determination method of the invention has high sensitivity and small error, so the determination method and the kit of the invention can be widely used in food inspection.

Description

【Technical field】 [0001] The invention relates to the technical field of food inspection and determination, more specifically, the invention relates to a glycine determination method and a kit thereof. 【Background technique】 [0002] Glycine is a non-essential amino acid. Glycine has a unique sweet taste, which can ease the acid and alkali taste, cover the bitter taste of saccharin added in food and enhance the sweet taste. If the human body consumes too much glycine, not only will it not be absorbed and utilized by the human body, but it will also break the body's absorption balance of amino acids and affect the absorption of other amino acids, resulting in nutritional imbalance and affecting health. Glycine cannot be used by the body, it can only be decomposed and converted into heat energy, which will increase the burden on the liver. The nitrogen-containing compounds in the decomposition products have to be excreted through the urine, which will increase the burden on ...
