Abstract

The invention discloses a method for co-crystallizing trehalose-D-psicose, and belongs to the technical field of functional sugar production. The invention discloses a trehalose-D-psicose co-crystallization method, which comprises the following steps: mixing trehalose and D-psicose according to a ratio, adding water for dissolving, and heating to 90-100 DEG C to prepare a clarified co-crystallization mother solution; cooling, adding a seed crystal after the cocrystallization mother liquor is cooled to 57-65 DEG C, growing the crystal, and then cooling and crystallizing in different areas to finally prepare the trehalose-D-psicose cocrystal. The trehalose-D-psicose co-crystallization method disclosed by the invention not only solves the problem that the D-psicose is easy to generate Maillard reaction, but also covers the bitterness of the psicose, and can greatly improve the application convenience of the D-psicose.

Description

technical field [0001] The invention relates to the technical field of functional sugar production, and more specifically relates to a trehalose-D-psicose co-crystallization method. Background technique [0002] D-psicose, also known as D-ribose-2-hexulose, is a kind of rare sugar, which was isolated from narrow mycin C (psicofuranine) for the first time. D-psicose is the epimer of D-fructose. At the molecular structure level, except for the inversion of the hydroxyl group and hydrogen group of the third carbon atom, the structure of D-psicose and D-fructose is the same. [0003] D-psicose has excellent properties and has been widely used in food at present. However, D-psicose itself is very hygroscopic, has strict requirements on storage temperature and humidity, and is prone to Maillard reaction, which has a bitter taste after eating, which greatly limits the application of D-psicose. [0004] Therefore, it is an urgent problem for those skilled in the art to provide a ...
