Ultrasonic-assisted accelerated solvent extraction method for vanilla tincture

Abstract

The invention discloses an ultrasonic-assisted accelerated solvent extraction method for vanilla tincture and belongs to the technical field of chemistry. The extraction method comprises the following steps: carrying out washing and dust removing on vanillas and then chopping; adding certain amount of an ethanol solvent into the chopped vanillas and pre-treating in an ultrasonic cell crusher; filtering the sample treated by ultrasounds and remaining a filtrate; transferring filtering dreg into an accelerating solvent extract material bottle to be extracted; and after extracting, cooling and standing to obtain clarified liquid, and mixing the liquid with the filtrate obtained by ultrasonic treatment to obtain the vanilla tincture. Compared with an existing tincture preparation method, the production period of the method can be greatly shortened, the use amount of the extracting solvent is reduced and the yield of effective components is extremely improved. The quality of the vanilla tincture prepared by the method is remarkably better than that of the vanilla tincture prepared by a conventional vanilla extracting method.

Description

technical field

[0001] The invention relates to the technical field of preparing natural plant tincture, in particular to a method for accelerating solvent extraction of vanilla tincture by means of ultrasound. Background technique

[0002] Vanilla bean is a precious natural food spice, which is widely used in medicine, food and other fields because of its plump and rich aroma. Due to the backward tincture preparation technology, the extraction process takes a long time and the yield of active ingredients is low, resulting in a serious waste of resources. Therefore, new extraction methods are continuously applied in the preparation of tinctures to improve the extraction efficiency and quality of tinctures.

[0003] With the development of science and technology, ultrasonic cell disruption and accelerated solvent extraction technology have been widely used in recent years. Ultrasonic cell disruption technology uses ultra-high pressure energy to destroy the cell membrane and...
