Problems solved by technology

[0004] However, there are many problems in the existing methods, such as the need to keep the heating temperature at 100 degrees Celsius or above. On the one hand, due to the high temperature, the components are likely to change, resulting in changes in the smell; , making collection difficult, low extraction rate and cumbersome steps

Abstract

The invention relates to the technical field of plant extraction, in particular to an extraction method of a rose extract. The method comprises steps as follows: after rose pedals are cleaned, the rose pedals are mixed with deionized water, pectinase and cellulase are added after ultrasonic sterilization, rose cell walls are removed, lipids, vitamins and protein are promoted to be released, and the extraction rate is increased; lactobacillus plantarum is added for fermentation, total sugar of the rose solution is reduced after fermentation, and the content of free amino acid, general flavone and VC is increased; a polar solvent is added to a fermentation solution, ultrasonic extraction and filtration are performed, centrifugal filtration is performed, a centrifugal liquid is obtained and subjected to macroporous resin treatment, treated filtrate is deluted with an alcohol solution, an eluant is subjected to reduced pressure concentration and freeze drying, and the rose extract is obtained. The extract has a preservative effect, preservatives are not additionally added, the safety, the efficacy and the stability of a product are guaranteed. The provided extraction method is simple to operate and various complicated extraction processes are avoided.

Description

technical field [0001] The invention relates to the technical field of plant extraction, in particular to a method for extracting rose extract. Background technique [0002] Rose extract is a general term for various rose bud processing extracts. Rose is a spice plant, and the spice extracted from roses - rose essential oil, is expensive in the international market and has the reputation of "liquid gold". In the prior art, the extraction method of rose extract rose essential oil is mainly steam distillation, and its process, equipment, operation and other technologies are relatively mature, with low cost and large output, and relatively simple equipment and operation. [0003] The existing steam distillation method can be divided into water distillation method and water distillation method from the distillation method. Distillation in water is a method in which plant materials are directly soaked in water and then heated and distilled; water distillation is a method in whi...
