Problems solved by technology

Because there will be petroleum ether residues in the rose oil extracted by petroleum ether, which will not only affect the quality of cigarettes, but also increase the hazards of cigarettes, so the rose oil extracted by this method is not suitable for use in cigarettes

Embodiment 1

[0033] Take 1000g edible-grade olive oil and extract it with 2000g absolute ethanol each time for a total of 3 extractions. Put 200g of dried rose petals into a flat-bottomed flask, pour 1000g of extracted olive oil into the flat-bottomed flask, stir with a glass rod until all the dried rose petals can be soaked in olive oil, and soak for 24 hours. Let the flat-bottomed flask be placed in an ultrasonic extraction device for ultrasonic extraction for 4 hours, and use a 40-mesh filter to filter out the rose petals in the olive oil. Then each time the olive oil filtered out was extracted with 3000g of dehydrated ethanol, which was extracted three times in total, and the dehydrated ethanol phases were combined. The extracted olive oil is reserved for reuse next time. Put the combined anhydrous ethanol phase into the environment of minus 18°C ​​and freeze for 12 hours, take it out from the cold storage and filter it immediately, and concentrate the filtrate under reduced pressure ...

Embodiment 2

[0035] Take 2000g edible grade olive oil, extract with 2000g absolute ethanol each time, extract altogether 3 times. Put 300g of dried rose petals into a flat-bottomed flask, pour 2000g of extracted olive oil into the flat-bottomed flask, stir with a glass rod until all the dried rose petals can be soaked in the olive oil, and soak for 48 hours. Let the flat-bottomed flask be placed in an ultrasonic extraction device for ultrasonic extraction for 3 hours, and use a 60-mesh filter cloth to filter out the rose petals in the olive oil. Then the olive oil filtered out was extracted with 2000 g of dehydrated ethanol each time, and extracted three times altogether, and the dehydrated ethanol phase was combined. The extracted olive oil can be reused next time. Put the combined anhydrous ethanol phase into the environment of minus 18 ℃ and freeze for 12 hours, take it out from the cold storage and filter it immediately, and concentrate the filtrate under reduced pressure at a concent...

Abstract

The invention discloses an extraction process of rose essence for cigarette, falling into the technical field of essence and flavoring extraction technique. The extraction process includes pretreating olive oil; immersing; ultrasonically extracting; filtering; extracting; freezing and concentrating under reduced pressure; and performing molecular distillation. In the extraction process, rose oil in rose leaves can be fully dissolved in the olive oil to improve extraction yield; and the olive oil is extracted by anhydrous ethanol for multiple times before being used to reduce impurities in the rose oil, thereby reducing or eliminating residue in oral cavity resulting from lipoids in essence for cigarette.

Description

technical field [0001] The invention belongs to the technical field of essence and fragrance extraction, and in particular relates to a method for extracting rose essential oil from roses and dried roses. Background technique [0002] With the development of science and technology, the development of natural flavors and fragrances for tobacco is becoming more and more rapid. Relevant researchers have added various harmless natural flavors and fragrances to cigarettes in pursuit of improving the taste of cigarettes and reducing the hazards of cigarettes. Volatile oil is a kind of very good additives for cigarettes, which can not only reduce the harm of cigarettes, but also endow cigarettes with various elegant aromas, and improve the aroma and aroma of cigarettes. However, many natural plants have low oil content, and it is difficult to obtain volatile oil, so the price of the final essential oil is very expensive. Such as rose oil, because of its low oil content, its price ...
