Abstract

A solid composition for removing color impurities in sugar liquor or syrup and a method of using said solid composition, in which said solid composition comprises at least a quaternary ammonium compound and a phosphoric compound.

Description

[0001] This application claims priority to PCT International Patent Application No. PCT / CN2016 / 083428 filed on May 26, 2016, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0002] The present invention relates to a solid composition for sugar purification. The solid composition can remove colored impurities in sugar liquid or syrup. The solid composition comprises a quaternary ammonium compound and a phosphorus compound. Background technique [0003] Refined sugar is usually obtained by purifying raw sugar or sugar juice. For example, raw sugar can be obtained from sugar juice by purifying, evaporating into a thick syrup, and crystallizing. The crystallized product can then be dissolved in water in order to obtain a sugar solution. Subsequently, the sugar liquor can be further purified and processed to obtain refined sugar with acceptable purity standards. Alternatively, the syrup obtained from sugar juice can be subj...
