Processing method of peppermint extract dry powder and pear loquat dew

Abstract

The invention discloses a processing method of peppermint extract dry powder and pear loquat dew. In the preparation of peppermint extract dry powder, microwave drying is firstly used to keep the natural green color and fresh flavor of mint to the greatest extent, and after drying, it is convenient for preservation so as to be processed in the next step; secondly , enzymatic hydrolysis + ultrasonic extraction, the tissue structure of mint leaves is destroyed by enzymatic hydrolysis, which is beneficial to the extraction of active ingredients of mint, and ultrasonic vibration greatly speeds up the extraction efficiency. The extraction of the effective components of the leaf, compared with the traditional extraction temperature above 80 ℃, the mint flavor is better under this process extraction condition; moreover, the reverse osmosis concentration and vacuum drying adopt the method of non-heat treatment to concentrate and dry the mint extract, which retains more Fresh flavor ingredients in mint. However, the Sydney Loquat Loquat prepared from the dry powder of mint extract still maintains the fresh flavor of mint, and at the same time has the function of cooling and nourishing the lungs.

Description

technical field

[0001] The invention relates to a processing method of peppermint extract dry powder and pear loquat dew. Background technique

[0002] At present, there are generally two types of mint extract technology in the food and drug industry: 1. After extraction from ordinary dried mint, it is purified into relatively pure mint components such as mint oil, menthol, menthol, etc. These components are used as functional ingredients in medicines Or the cooling ingredients in food flavors no longer have the natural fresh flavor of mint; 2. The mint crude extract obtained from ordinary dried mint through high-temperature water extraction, concentration and drying has a strong herbal flavor, but the freshness of mint, The novelty is lost. Furthermore, the peppermint extracts currently produced in the food and drug industry have no specific restrictions on the species and origin of peppermint, which makes the final peppermint extract unsatisfactory and unstable.
