Abstract

The invention provides a refining method of novel menthol. The refining method comprises the following steps: (1) carrying out esterification reaction on menthol, thus synthesizing menthyl acrylate; (2) synthesizing a modified calcium alginate gel carrier, and fixing lipase through the calcium alginate gel carrier; and (3) carrying out chiral resolution on menthol by adopting the fixed lipase, thus obtaining L-menthol. According to the refining method provided by the invention, the used raw materials are safe, the resolution selectivity is high, and the prepared L-menthol is high in optical purity and good in effect when used for cigarettes; the technological conditions are mild, the product can be recycled for a plurality of times, and the application prospect is wide.

Description

technical field

[0001] The invention belongs to the field of spice preparation, in particular to a novel method for refining menthol. Background technique

[0002] Organisms perceive the aroma of spices and essences through enzymes in the organism or receptor molecules on the cell surface, and the enzymes in the organism or receptor molecules on the cell surface are chiral molecules, and their basic units are carbohydrates Compounds, amino acids, etc. are also chiral, so compounds with the same chemical structure have different aromas due to their different chiralities. In 1961, Ohloff published the aroma properties of the first chiral fragrance (+)-β-citronellol 1. (+)-1 has citronellal fragrance, (-)-1 has geranium oil fragrance. Subsequently, it was discovered that the different enantiomers could exhibit different fragrances or different degrees of fragrance. Chiral fragrances with different optical purity can also exhibit different odor thresholds. The importance of ...
