Rose fresh water and preparation method and application thereof

Abstract

The invention discloses rose fresh water and a preparation method and application thereof. The preparation method of the rose fresh water includes the following steps that roses are arranged in a reactor, and vacuumizing is conducted; then reduced pressure distillation is conducted, condensate is collected, and then the rose fresh water is obtained. The application of the rose fresh water to preparing products with at least one of the functions of skin whitening, age defying, free radical scavenging and tyrosinase restraining is provided. The preparation method is simple and practicable, no organic solvent is contained, no additive is contained, and safety is achieved. The rose fresh water can be applied to preparation of food, healthcare products and cosmetics.

Description

technical field [0001] The invention relates to rose fresh water and its preparation method and application, belonging to the fields of food, health products and cosmetics. Background technique [0002] Roses are warm in nature and sweet in taste. They have the effects of regulating qi and relieving depression, harmonizing blood and dispersing stasis, reducing swelling and pain, soothing the liver and relieving depression, reducing fat and losing weight, moisturizing skin and beautifying the skin. Hemostasis and convergence. In addition to natural pigments such as red pigment, yellow pigment and β-carotene, roses are also rich in various aromatic ethers, alcohols, phenols, esters such as linalool, cis-rose ether and trans-rose ether. , aldehydes, fatty oils, cyclic peptides, proteases, polyphenol antioxidants, organic acids and other substances that are beneficial to beauty. Long-term consumption of roses can make people have a fresh body fragrance, improve dry, hardened o...

AI Technical Summary

Problems solved by technology

The main problem of the boiling method is that the long-term high-temperature cooking makes the aromatic alcohol esters of roses mutate, and the extracted active substances do not have the natural fragrance of flowers, but are strong and pungent, and the smell is impure. , a lot of equipment, high energy consumption, many operators, low efficiency, large amount of residual liquid and residue pollution, and consumes a lot of steam and cooling water; the second is "solvent extraction method", using organic solvents, such as alcohol, ether or Liquid butane, etc., repeatedly sprinkle the organic solvent on the fresh roses, dissolve the aromatic substances in the flowers into the organic solvent, and then use low-temperature distillation to extract the aromatic substances in the roses

The main problems of the solvent extraction method are that the equipment and process are complicated, and steam and cooling water are also consumed. Due to the use of organic solvents, the investment is large, the output is low, and it is easy to pollute the active substances, the oil yield is low, and the separated activity The substance is impure; the third is "carbon dioxide supercritical extraction method", the extraction process is to use CO 2 In a low-temperature critical environment, the aromatic substances in roses are extracted. This process adapts to the low-temperature aromatic characteristics of roses. The extracted active substances have pure fragrance and are very similar to flowers.

The main problem of carbon dioxide supercritical extraction method is that the equipment and process are very complicated, the processing capacity is low, the equipment investment is expensive, and there is also waste residue discharge to pollute the environment. At present, this method is only in the laboratory stage, and there is no precedent for mass production of enterprises using this method.
