Embodiment 1

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

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

[0019] 3) Use a polyethylene (HDPE) plastic filter screen with a pore size of 3 mm to separate the rose residue from the solution,

[0020] 4) After passing the liquid part (about 18kg) through the column with 200g of macroporous resin SP70 (the macroporous resin SP70 is loaded into the chromatography column to make a column with a diameter of 5cm and a height of 15cm), rinse with 200ml of 95% ethanol each time , rinsed three times to obtain a pigment solution, carried out 2h precipitation, and then filtered out the precipitates such as p...

Embodiment 2

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

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

[0029] 3) Use a polyethylene (HDPE) plastic filter screen with a pore size of 3 mm to separate the rose residue from the solution.

[0030] 4) After passing 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), rinse with 300ml of 95% ethanol each time , washed three times to obtain the pigment solution, carried out 2h precipitation, and then filtered out the...

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 method of making rose water that contains natural rose pigment. Background technique [0002] The current skin care water uses the flower water of natural aromatic plants, of which rose water is the most common, and is favored for its moisturizing, moisturizing, whitening and other effects. However, most of these flowers are colorless, losing the unique color of the original aromatic plants. [0003] The rose material used in the present invention specifically refers to roses used for extracting essential oils, such as double roses, purple roses, bittersweet roses, Fenghua roses, Damascus roses, "ink red" roses, and the like. In addition to extracting rose essential oil, these roses can also extract rose pigment, rose water, etc. Usually rose water is extracted by steam distillation. Due to the high temperature of distillation, the pigment of the rose is destroyed, which n...
