Embodiment 1

[0022] Such as figure 1 As shown, this embodiment provides a method for extracting rose extract, including step S110, step S120, step S130, step S140 and step S50.

[0023] Step S110. Washing the rose petals and mixing them with deionized water, sterilizing them with ultrasonic waves for 8 minutes, adding pectinase and cellulase, to obtain the first rose pulp;

[0024] Step S120. Adding Lactobacillus plantarum to the first rose syrup, fermenting at 35°C for 2 days to obtain the second rose syrup;

[0025] Step S130. Adding a polar solvent 12 times the weight of rose petals to the second rose pulp, performing ultrasonic extraction and filtering to obtain the third rose pulp;

[0026] Step S140. Centrifuge and filter the third rose pulp, and perform macroporous resin adsorption treatment on the obtained centrifugate, elute the treated filtrate with an ethanol solution with a mass fraction of 65%, and collect the ethanol eluate to obtain the fourth rose syrup;

[0027] Step S1...

Embodiment 2

[0036] This embodiment provides a method for extracting rose extract, including step S210, step S220, step S230, step S240 and step S250.

[0037] Step S210. Washing the rose petals and mixing them with deionized water, sterilizing them with ultrasonic waves for 10 minutes, adding pectinase and cellulase to obtain the first rose pulp;

[0038] Step S220. Adding Lactobacillus plantarum to the first rose syrup, fermenting at 40°C for 1 day to obtain the second rose syrup;

[0039] Step S230. Adding a polar solvent 15 times the weight of rose petals to the second rose pulp, performing ultrasonic extraction and filtering to obtain the third rose pulp;

[0040] Step S240. Centrifuge and filter the third rose pulp, and perform macroporous resin adsorption treatment on the obtained centrifugate, elute the treated filtrate with an ethanol solution with a mass fraction of 70%, and collect the ethanol eluate to obtain the fourth rose syrup;

[0041] Step S250. Put the fourth rose syru...

Embodiment 3

[0050] This embodiment provides a method for extracting rose extract, including step S310, step S320, step S330, step S340 and step S350.

[0051] Step S310. Washing the rose petals and mixing them with deionized water, sterilizing them with ultrasonic waves for 6 minutes, adding pectinase and cellulase, to obtain the first rose pulp;

[0052] Step S320. Adding Lactobacillus plantarum to the first rose syrup, fermenting at 30°C for 3 days to obtain the second rose syrup;

[0053] Step S330. Adding a polar solvent 10 times the weight of rose petals to the second rose pulp, performing ultrasonic extraction and filtering to obtain the third rose pulp;

[0054] Step S340. Centrifuge and filter the third rose pulp, and subject the obtained centrifugate to macroporous resin adsorption treatment, elute the treated filtrate with an ethanol solution with a mass fraction of 60%, and collect the ethanol eluate to obtain the fourth rose syrup;

[0055] Step S350. Put the fourth rose syr...

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...
