8 Claims

1. A method for increasing a yield of Amadori rearrangement products (ARP), wherein the method is based on a mechanism of inhibiting a degradation of the Amadori rearrangement products by adding tea polyphenols to deoxyosones, and the method comprises the following steps:

(1) dissolving and mixing amino acid, sugar, and the tea polyphenols in water to obtain a mixed solution, and adjusting a pH value of the mixed solution;

(2) placing the mixed solution obtained in step (1) in a reaction flask, and heating the reaction flask at a constant temperature in a water bath to obtain a reaction solution; and

(3) performing a vacuum decompression dehydration reaction on the reaction solution obtained in step (2) at a constant reaction temperature; after the vacuum decompression dehydration reaction is completed, using an ice bath to terminate the vacuum decompression dehydration reaction to obtain a solid reactant; and redissolving the solid reactant in water to obtain an ARP solution, wherein in step (3), an ARP yield in the ARP solution is 80% or above.
