Embodiment 1

[0052] Pick fresh roses, cut them into pieces and grind them into powder, and set aside; weigh 10.0g of spare samples, deproteinize them with papain and alkaline protease respectively, add 180mL of pure water, put them into a high-pressure reactor, seal and stir Mix evenly, heat up to 110°C and react for 1.5h, the reaction pressure is 0.15MPa, the obtained crude product is suction-filtered with a filter membrane of 0.45μm, the obtained filtrate is washed with pure water, and the washing liquid is incorporated into the filtrate, with 1% Activated carbon was decolorized at 50°C for 3 times, each time for 1.5h, to obtain rose flower water.

Embodiment 2

[0054] Pick fresh roses, cut them into pieces and grind them into powder, and set aside; weigh 10.0g of spare samples, deproteinize them with ficin and cathepsin respectively, add 200mL of pure water, put them into a high-pressure reactor, seal and mix Evenly, heat up to 100 ° C for 2 hours, the reaction pressure is 0.1 MPa, the obtained crude product is filtered by a 0.22 μm filter membrane, the obtained filtrate washes the filter residue with pure water, and the washing liquid is incorporated into the filtrate. Decolorize twice at 55°C, each time for 4 hours, to obtain rose flower water.

Embodiment 3

[0056] Pick fresh roses, cut them into pieces and grind them into powder for later use; weigh 10.0g of spare samples, deproteinize them with bromelain and Aspergillus oryzae acidic protease respectively, add 150mL of pure water, put them into a high-pressure reactor, and seal them. Stir and mix well, heat up to 100°C and react for 3 hours, the reaction pressure is 0.1MPa, the obtained crude product is suction-filtered with a 0.2μm filter membrane, and the obtained filtrate is washed with pure water to wash the filter residue, and the washing liquid is incorporated into the filtrate, and 2% Activated carbon was decolorized at 40°C for 3 times, 5 hours each time, to obtain rose flower water.

Abstract

The invention provides a rose water and an extraction method and application thereof. The method comprises the following steps: (1) deproteinization: deproteinizing rose flower powder; (2) extraction: adding a deproteinized rose flower sample Add extraction solvent into the reaction kettle, and extract to obtain the rose water. The extraction method of the invention has a simple process, and combines high-pressure hydrothermal extraction, deproteinization and decolorization treatment, thereby significantly improving the content and transparency of the water-soluble polysaccharide in the rose water.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and relates to rose water, an extraction method and application thereof. Background technique [0002] Since ancient times, roses have been a natural beauty and skin care product, which has the functions of promoting blood circulation and removing blood stasis, eliminating endocrine dysfunction, lightening pigmentation, and treating facial acne. Roses contain more than 300 chemical components, among which polyphenols such as tannins, proanthocyanidins, flavonoids and β-carotene help to remove free radicals in the body and delay aging, and have high application value. [0003] At present, rose essential oil is mostly used as an active ingredient in cosmetics. Rose essential oil is known as "liquid gold" and has the functions of anti-sensitivity, beauty, moisturizing, lightening pigment, promoting cell regeneration, and alleviating skin aging. However, rose essential oil is expensive and is main...
