Embodiment 1

[0052] Pick fresh roses, cut them into pieces and grind them into powder for use; weigh 10.0g of spare samples, deproteinize them with papain and alkaline protease, add 180mL of pure water, put them in a high-pressure reactor, seal and stir Mix well, heat up to 110°C and react for 1.5h, the reaction pressure is 0.15MPa, the obtained crude product is suction filtered through a 0.45μm filter membrane, the obtained filtrate is washed with pure water, and the filter residue is washed with pure water. The activated carbon was decolorized three times at 50°C for 1.5 hours each time to obtain rose water.

Embodiment 2

[0054] Pick up fresh roses, cut them into pieces and grind them into powder for use; weigh 10.0 g of the spare samples, deproteinize them with ficin and cathepsin, add 200 mL of pure water, put them in a high-pressure reactor, seal and stir to mix. The obtained crude product was filtered with a 0.22 μm filter membrane, the obtained filtrate was washed with pure water, and the filter residue was washed with pure water. Decolorization was carried out twice at 55°C for 4 hours each time to obtain rose water.

Embodiment 3

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

Abstract

The invention provides rose flower hydrosol as well as an extraction method and application thereof. The method comprises the following steps: (1) carrying out protein removal: carrying out protein removal treatment on rose flower powder; (2) extracting: adding an extraction solvent into a protein-removed rose flower sample and adding a mixture into a reaction kettle; extracting to obtain the roseflower hydrosol. The extraction method provided by the invention has a simple technology; high-pressure hydrothermal extraction, protein removal and de-coloring treatment are combined, so that the content of water-soluble polysaccharides in the rose flower hydrosol and the transparency of the rose flower hydrosol are remarkably improved.

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...
