Description
Technical Field
The invention relates to the technical field of plant processing, and particularly relates to rose hydrosol prepared from a new rose variety and a preparation method of the rose hydrosol.
Background
The hydrolat, also called water essential oil (hydrate), refers to a 100% saturated distillation stock solution separated during the extraction of essential oil during the distillation extraction process, which is a byproduct of essential oil, and has natural and pure components and light and pleasant fragrance. The hydrosol is condensed water solution obtained by distilling aromatic plants. During the distillation and extraction, oil and water are separated, and the essential oil floats on the essential oil due to different densities, and water is precipitated on the essential oil and is called hydrolat. The pure dew contains small amount of essential oil components, and also contains water soluble substances in plant body. It has a pure dew of water-soluble substances of one hundred percent plants, and mineral nutrients (such as tannic acid and flavonoid) contained in the dew are deficient in essential oil. The low-concentration characteristic of the facial mask is easy to be absorbed by skin, no essence or alcohol component exists, the facial mask is mild and non-irritating, and the pure dew can be used every day and can also replace pure water to prepare various facial masks and the like.
The rose hydrosol not only can be drunk, but also can be used in products such as various skin care products, hair conditioners and the like, can regulate the endocrine of a human body, can clean the skin, supplement water and the like, has various effects, and therefore has extremely high economic value.
Therefore, there is a need to provide a rose hydrosol with higher nutritional value.
Disclosure of Invention
The invention aims to provide rose hydrosol prepared from a new rose variety, which is prepared from a new rose variety, contains more beneficial components than common rose hydrosol and has better effects of moisturizing and whitening skin and regulating human endocrine.
The invention also aims to provide a preparation method of the rose hydrosol prepared from the new rose variety, which adopts the traditional distillation method to prepare the rose hydrosol and adjusts the distillation time and temperature according to the water content in the new rose variety, thereby avoiding the decomposition of beneficial components in the rose hydrosol due to overhigh distillation temperature or overlong distillation time and ensuring the content of the beneficial components as much as possible.
The technical problem to be solved by the invention is realized by adopting the following technical scheme.
On one hand, the rose hydrosol prepared from the new rose variety comprises the following raw materials, by weight, 50-70 parts of the new rose variety and 90-140 parts of water, wherein the new rose variety is obtained by hybridizing and carrying out tissue culture on Yunnan plateau rose and Yunnan Xueshan rose.

The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to specific examples.
On one hand, the embodiment of the invention provides rose hydrosol prepared from a new rose variety, which comprises the following raw materials in parts by weight, 50-70 parts of the new rose variety and 90-140 parts of water. The rose new variety contains abundant 7-octenoic acid ethyl ester and geranyl acetate, wherein the 7-octenoic acid ethyl ester has specific fragrance and can be eaten, not only can add the fragrance of rose hydrosol, but also can enhance the taste of the hydrosol, and improve the activity of cells decomposing food in human intestines and stomach, thereby improving the metabolic rate of human intestines and stomach, promoting the absorption of human body to nutrient substances, also can moisturize when being used externally, and promote the metabolism of skin cells, thereby enabling the skin to be more white and clean, and can also placate the mood of users because of the unique fragrance, so that people can relax and have joyful mood. The rose hydrosol provided by the invention has higher geranyl acetate content, so that the fragrance of the rose hydrosol is stronger, the people feel happy, the sweetness of the rose hydrosol can be further increased, the taste of the rose hydrosol is improved, and no sugar is required to be added when the rose hydrosol is drunk, so that the problem of higher calorie of the rose hydrosol caused by adding sugar for increasing the taste of the rose hydrosol when the rose hydrosol is drunk is solved. The Yunnan Xueshan rose has thick flower forms and rich layers, the Yunnan plateau rose has unique fragrance, and contains various components beneficial to human skin, such as beta-citronellol, trans-geraniol, beta-phenylethyl alcohol, 7-octenoic acid ethyl ester, geranyl acetate and the like, but whether the components are contained is judged according to the unique fragrance of the Yunnan plateau rose, so that the screened rose containing the unique fragrance of the plateau rose and the characteristic flower forms of the Xueshan rose has extremely high economic value, can make people smell the fragrance of the mind and the spleen of people when being used for decoration and beauty, and can also be used for manufacturing products with higher nutritional values, such as cosmetics, essential oil and the like. The Yunnan plateau rose and the Yunnan snow mountain rose belong to relatively excellent varieties of the plateau rose and the snow mountain rose respectively, are produced in Yunnan, are convenient to hybridize, and have higher hybridization affinity and are easier to succeed compared with varieties of other producing places. And F1 progeny needs to be selfed at least four times to obtain the rose with both the two traits being stably inherited.
On the other hand, the embodiment of the invention also provides a preparation method of the rose hydrosol prepared from the new rose variety, which comprises the following steps of airing the new rose variety, detecting the water content of the rose variety, mixing the aired new rose variety with water when the water content is not more than 5% to obtain a mixture, adding the mixture into a distillation device for distillation for 30-50min to obtain a suspension, filtering the suspension to obtain a mixed solution, standing the mixed solution for 15-20h, and extracting a supernatant to obtain the rose hydrosol. Because the temperature and the time are adjusted according to the water content of the new rose variety during distillation, the phenomenon that the concentration of the beneficial substances in the rose hydrolat is too low or the beneficial substances cannot be completely distilled off due to insufficient distillation temperature and distillation time when the water content in the new rose variety is too high is avoided, and the phenomenon that the beneficial substances in the rose hydrolat are evaporated or lost after the water in the new rose variety is completely evaporated due to too high distillation temperature or too long distillation time when the water content in the new rose variety is too low is also avoided, so that the content of the beneficial substances in the rose hydrolat is too low. When the water content in the new rose variety exceeds 5%, the distillation efficiency of the beneficial components in the new rose variety is influenced during distillation, so that the beneficial components are more difficult to distill, and the nutritional value of the prepared rose hydrosol is lower.
In some embodiments of the present invention, the weight ratio of the new air-dried rose variety to water is 1 (15-25). The beneficial components in the new rose variety can be in proper concentration through proper water amount. When the amount of water added is too large, the concentration of the beneficial component is low, the prepared hydrosol has poor effect, and when the amount of water added is too low, part of water is evaporated together with the beneficial component during distillation, so that the beneficial component is lost.
In some embodiments of the present invention, the mixture further comprises stirring before the distillation, wherein the stirring speed is 200-300rpm, and the stirring time is 10-15 min. The cell wall and cell membrane in the new rose variety can be damaged by stirring, so that the beneficial components in the cell matrix are fully mixed with the deionized water, and the beneficial components such as 7-octenoic acid ethyl ester and other aromatic alcohols are conveniently and fully distilled during distillation, so that the content of the beneficial substances in the rose hydrosol is increased.
In some embodiments of the invention, the distillation comprises a primary distillation at a temperature of 60 to 70 ℃ for a period of 20 to 30 min. Beneficial substances with lower melting point or easy loss such as 7-octenoic acid ethyl ester in the new rose variety are distilled out through the primary distillation mode, so that the situation that the beneficial substances with lower melting point or easy loss are volatilized or decomposed when the primary distillation temperature is too high or the primary distillation time is too long is avoided, and the content of the beneficial substances in the finally prepared rose hydrosol is lower. The temperature and the time of the primary distillation are in direct proportion to the water content of the new rose variety, when the water content of the new rose variety is 5% of the maximum value, the temperature and the time of the primary distillation respectively reach the maximum value of 70 ℃ and 30min, when the water content of the new rose variety is less than 1%, the temperature and the time of the primary distillation respectively reach the minimum value of 60 ℃ and 20min, and when the water content of the new rose variety is 1% -5%, the temperature and the time of the primary distillation are adjusted according to the situation.
In some embodiments of the present invention, the distillation further comprises a secondary distillation, wherein the temperature of the secondary distillation is 80-90 ℃, and the time of the secondary distillation is 10-20 min. The water in the rose hydrosol can be further evaporated through secondary distillation, and the concentration of beneficial substances in the finally prepared rose hydrosol is further improved. And there is no fear of loss of the beneficial agent because the beneficial agent, of which the melting point is low and which is easily lost, has been distilled off. The temperature and the time of the secondary distillation are in direct proportion to the water content of the new rose variety, when the water content of the new rose variety is 5% of the maximum value, the temperature and the time of the secondary distillation respectively reach the maximum value of 90 ℃ and 20min, when the water content of the new rose variety is less than 1%, the temperature and the time of the secondary distillation respectively reach the minimum value of 80 ℃ and 10min, and when the water content of the new rose variety is 1% -5%, the temperature and the time of the secondary distillation are adjusted according to the situation.
In some embodiments of the invention, the primary distillation and the secondary distillation each comprise vacuum distillation. Vacuum distillation is carried out under reduced pressure and is generally used to separate substances that tend to decompose when heated to boiling point at atmospheric pressure, or in conjunction with other distillation methods (e.g., steam distillation) to reduce the distillation temperature and increase the separation efficiency. The beneficial components in the new rose variety can be almost completely separated out through vacuum distillation, so that the beneficial effect of the prepared rose hydrosol is improved.
In some embodiments of the invention, the pore size of the filtration is 3-5 μm. Through the filtering membrane with the aperture, impurities in the suspension can be fully filtered, and dead large cells are filtered out, so that the purity of the finally prepared rose hydrosol is improved.
In some embodiments of the present invention, the above-mentioned extracting of the supernatant further comprises a sterilization treatment, the sterilization treatment comprises the following steps, the frequency is 5 × 103-5×105Heating with MHz microwave for 2-5 min. The rose hydrosol contains more moisture, and because more moisture has good absorption effect on microwaves, the microwave heating mode is adopted for sterilization, and the microwave heating can enable the temperature to be increased more quickly, so that the sterilization efficiency is improved.
In some embodiments of the present invention, the above-mentioned extracting of the supernatant further comprises a preservative treatment, the preservative treatment comprises adding a preservative to the supernatant, the preservative comprises one or more of 0.1% sodium citrate, 10 wt% glycerol or 1, 2-hexanediol. Although the rose hydrosol has a certain antibacterial property and can be stored for a certain time under the condition of cool and dry, the rose hydrosol is not beneficial to long-term storage, so that some preservatives are required to be properly added while the property of the rose hydrosol is not influenced, wherein 0.1 percent of sodium citrate and 1, 2-hexanediol have a certain antibacterial effect, can kill some common mixed bacteria, and cannot influence the taste and use of the rose hydrosol, and 10 percent of glycerol can isolate the rose hydrosol from the outside, so that the mixed bacteria are prevented from entering the rose hydrosol.
