Embodiment 1

[0017] 1) take fresh rose 4kg, utilize sub-vacuum cryogenic extraction device to obtain rose water 1 and dry rose is about 2.3kg, the amount of rose water 1 is about 1.6kg.

[0018] 2) Put 2.3kg of roses into a sealable glass container, add 20kg of ultrapure water, extract them in an ultrasonic device for 1 hour, and then extract them in a low-temperature constant temperature water bath at 50°C for 2 hours until the petals turn white.

[0019] 3) Utilize the polyethylene (HDPE) plastic strainer filter that aperture is 3mm to separate rose residue and solution,

[0020] 4) Pass the liquid part (about 18 kg) through the column with 200 g of macroporous resin SP70 (the macroporous resin SP70 is loaded into the chromatography column to make a column with a diameter of 5 cm and a height of 15 cm), and rinse with 200 ml of 95% ethanol each time , wash three times to obtain the pigment solution, carry out 2h precipitation, and then filter out protein and polysaccharide and other prec...

Embodiment 2

[0027] 1) take fresh rose 10kg, utilize sub-vacuum extraction device to obtain rose water I and dry rose about 5kg at 50 degrees, the amount of rose water I is about 5kg.

[0028] 2) Put 5kg of roses into a sealable glass container (light-shielding condition), add 40kg of ultrapure water, extract in an ultrasonic device for 2 hours, and then extract in a low-temperature constant temperature water bath at 50°C for 2.5 hours until the petals turn white.

[0029] 3) Utilize the polyethylene (HDPE) plastic strainer screen filter that pore diameter is 3mm to separate rose residue and solution.

[0030] 4) Pass the liquid part (about 35kg) through the column with 300g of macroporous resin SP70 (the macroporous resin SP70 is loaded into the chromatography column to make a column with a diameter of 7cm and a height of 25cm), and then rinse with 300ml of 95% ethanol each time , wash three times to obtain the pigment solution, carry out 2h precipitation, and then filter out protein and ...

Abstract

The invention discloses a method for manufacturing rose water containing a natural rose pigment. The rose water is prepared by the following steps of: obtaining rose water I with natural fragrance of rose from fresh rose by using a sub vacuum low-temperature extraction device, extracting the dried and dehydrated rose for certain time by using ultrasonic, then obtaining solution containing rose pigment in a constant low temperature water bath, filtering the solution, filling the filtrate into resin, flushing the resin by using ethanol to obtain pigment solution, evaporating the ethanol from the pigment solution by using a rotary evaporation method to form rose pigment, distilling the residue by using water vapor to obtain rose water II, and mixing the rose water I and the rose water II to form the rose water; and adding the rose pigment into the rose water again, and then adding roselle pigment solution to obtain the rose water containing natural pigment, presenting rose red luster and keeping the natural fragrance of the rose.

Description

technical field [0001] The invention belongs to the technical field of cosmetics. Especially about a preparation method of rose water containing natural rose pigment. Background technique [0002] The skin care water used now uses the flower water of natural aromatic plants, among which rose water is the most common, and is favored for its multiple functions such as moisturizing, moisturizing, and whitening. However, most of these flower waters are colorless and lose the unique color of the original aromatic plants. [0003] The rose material used in the present invention refers specifically to roses used for extracting essential oils, such as double roses, purple branch roses, bitter water roses, Fenghua roses, Damascena roses, "ink red" roses, etc. In addition to extracting rose essential oil, these roses can also extract rose pigment, rose water and so on. Usually, rose water is extracted by steam distillation. Due to the high temperature of distillation, the pigment o...
