Abstract

The invention relates to a rapid detection method for the balance stability of folic acid content in an infant complementary food nutrition bag, which belongs to the technical field of infant complementary food nutrition bag product creation. The invention discloses a rapid detection method for detecting the folic acid content of an infant complementary food nutrition bag based on a liquid chromatography HPLC method and a folic acid content equilibrium stability judging model Y=0.876X+11.131, a model R<2>=0.944 and a P value=0.000<0.05. The model is remarkable at the verification level of 0.05, the root mean square error RMSE of the model is equal to 2.245843, and the standard deviation between a measured value and a predicted value is smaller than or equal to 0.768024. The method not only can be widely applied to the field of rapid detection of the folic acid content in folic acid-rich fortified food, but also can be applied to detection of the folic acid fortified equilibrium stability state in different batches of infant complementary food nutrition bags, and can rapidly guide production to improve the superior product rate of the infant complementary food nutrition bags.

Description

technical field [0001] The invention belongs to the technical field of the creation of nutritional supplements for infants and young children, and relates to a rapid detection method for the balance and stability of folic acid content in nutritional supplements for infants and young children, and a method for judging whether the nutritional packages for infants and young children rich in folic acid are in products under production or storage environments. A rapid test method for the equilibrium stability of folic acid content. Background technique [0002] Folic acid, also known as pteroylglutamic acid, is composed of three parts: 2-amino-4-hydroxy-6-methyl-pterinidine, glutamic acid and p-aminobenzoic acid. As a methyl donor, it is involved in many important The biochemical reaction process, especially in the synthesis and repair of vitamin B12 and vitamin B6, as well as the synthesis of purine pyrimidine and methylated DNA, plays an important role. Folic acid cannot be sy...
