Full utilization technology of rose flower

Abstract

The invention relates to a full utilization technology of rose flower. According to a special technology, rose flower resource can be converted into six product combinations, such as rose essential oil, rose pure dew, rose pigment, rose syrup, rose polyphenol and edible rose pollen. The resource utilization rate is 100%.

Description

1. Technical field: [0001] The invention relates to a process for full resource utilization of roses. 2. Background technology: [0002] Rose ( Rosa rugosa Thunb. ) is a deciduous shrub belonging to the family Rosaceae. It has beautiful flowers, color, fragrance and shape, and has extremely high economic value. It is known as the "golden flower". Rose essential oil is the crown of flower oils. It has an elegant, soft, delicate, honey-like, and fragrant rose fragrance, presenting a sweet rose fragrance. It has a strong fragrance, and two drops can be made into 1 L of good perfume. It is expensive and has the reputation of "liquid gold". High-end cosmetics and tobacco. [0003] Rose essential oil also has many curative effects on the human body. Spiritual curative effect: It has anti-depression, nervous tension, boosts the spirit, makes people excited, etc. Body curative effect: assists body circulation, can shrink microvessels, so it is a magical treasure for small vein r...

Problems solved by technology

[0024] However, due to the problem of development ideas, the above traditional processes still have many deficiencies in terms of resource utilization, process efficiency and product quality:

[0025] (1) In addition to rose essential oil, roses also contain a large amount of sugar, amino acids, proteins, polyphenols, organic acids, alkaloids, pigment flavonoids, tannins, waxes, etc., which have not been effectively developed and utilized. Said to be a great waste of resources;

[0026] (2) The traditional mainstream steam distillation method uses raw steam to directly heat the feed liquid, and some pollutants such as rust entrained in the raw steam also enter the extraction system, making the edible-grade raw materials that could be reused become non-edible Grade waste, resource reutilization rate drops sharply

[0028] (4) Since the extraction process is mostly high-temperature (100°C) normal-pressure extraction, many low-boiling components and heat-sensitive components in the petals are lost, especially the high-temperature loss of the representative component 2-phenylethanol in rose essential oil is the cause of rose essential oil. An important reason for the low yield;

[0029] (5) Some essential oil components are dissolved in water. Although the by-product rose hydrosol can also be sold as a commodity, the overall profit margin is still not as high as that of rose essential oil.
