Abstract
The invention discloses a green tea extract extracted by petroleum ether and a preparation method and application thereof. The green tea and the petroleum ether are mixed evenly, and the product is prepared after extraction, solid-liquid separation, distillation and concentration. The green tea extract extracted by petroleum ether is diluted to the concentration of 1-10% by using 95% ethanol, and then added into tobacco shreds according to 0.01-0.1% of the weight of the tobacco shreds, so that the tobacco is endowed with special fragrance. Meanwhile, free amino acids in the green tea can well participate in Maillard reaction to generate aroma substances in the alcoholization and combustion processes of the tobacco, and can neutralize alkaline substances in the tobacco, thereby reducing stimulation, enriching the fragrance of the tobacco, reducing stimulation and miscellaneous gas, and improving the taste and aftertaste. The invention has simple process and simple and convenient operation, does not need to change the prior production process, has no solvent pollution on the product, and has good application prospect.
Description
Technical field
The invention belongs to the cigarette additive preparing technical field, be specifically related to a kind of petroleum ether extracted green tea extract.Simultaneously, the invention still further relates to this extract making method and the application in cigarette thereof.
Background technology
The catechin and the antioxidant vitamins (comprising: beta carotene, vitamin e and Vitamin C etc.) that contain volume in the green tea, have pre-anti-cancer and delay senility effect.And the antioxidation of green tea is 20 times of vitamin e, can reduce oxygen production, effectively removes free radical, and the prevention geriatric disease is had suitable help.Studies confirm that green tea can also suppress that food preservative--nitrite changes carcinogen at human body, can suppress microsome ferment system and carcinogenic effect, stop the carrying out of oncogenic process, for benefiting of pre-anti-cancer.Green tea also helps to reduce fat, and except receiving the effect of fat-reducing, more can improve angiocardiopathy, suppresses blood sugar and rises, and reduces cholesterol and suppresses hypertension.Particularly green tea has significant antibacterial functions, not only helps to keep oral cavity fresh and cool, eliminates halitosis and prevents decayed tooth; Also help to remove and disintegrating breath road and tracheae,, play the effect of eliminating phlegm and cleaning lung because of the nicotine that smoking is accumulated.In addition, the caffeine in the green tea is under the influence of catechin, and its excitation is also mild relatively and lasting.
Tea aroma is one of important factor of decision tea leaf quality, therefore, always is subjected to tealeaves researcher's emphasis.According to the study, the fragrance component of green tea has kind more than 300, and constantly has new composition to be found evaluation.The green tea fragrance component mainly comprises terpene substances and derivatives thereof such as geraniol, linalool and oxide thereof, cloves alkene, farnesene, nerolidol; Suitable-the 3-hexenol, suitable-3 hexenoic aldehydes, caproic acid-suitable-Ester and derivatives thereof such as 3-second hexene ester; Phenmethylol, gaultherolin, methyl jasmonate, 6,10, aromatic derivants such as 14-trimethyl pentadecanone; Also contain materials such as pyrazine class, pyrans class, pyridines and derivative thereof.Main aroma component is phenmethylol, geraniol, pyrazine, suitable-the 3-hexenol.
Along with the problem of smoking with health more and more receives publicity, how to improve the security of sucking of cigarette, the harmful components in the reduction cigarette smoke, the comfort of aspirating that improves just become the focus of each tobacco productive corporation research and development.If the good characteristic that green tea had can combine with cigarette, should be able to address the above problem well, but not see as yet in the prior art that relevant report is arranged.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of petroleum ether extracted green tea extract is provided, use it for cigarette,, enrich cigarette cigarette perfume (or spice), improve the cigarette quality to reduce the harm of smoking to human body.
Another object of the present invention is to provide a kind of method for preparing described petroleum ether extracted green tea extract.
The present invention also aims to provide the application of a kind of described petroleum ether extracted green tea extract in cigarette.
Except as otherwise noted, percentage of the present invention is percetage by weight.
Purpose of the present invention is achieved by the following technical programs.
A kind of petroleum ether extracted green tea extract is prepared by following method: green tea and benzinum are mixed, obtain required green tea extract through extraction, Separation of Solid and Liquid, distillation after concentrating.
The invention provides a kind of method for preparing petroleum ether extracted green tea extract, this method comprises the step of following order:
(1) green tea and benzinum are mixed, the mixed weight ratio is 1: 5～15;
(2) extract 10h～20h at ambient temperature;
(3) Separation of Solid and Liquid is collected supernatant liquid;
(4) decompression distillation 0.5～2.0h under vacuum 0.01～0.1MPa, 25 ℃～30 ℃ conditions of vapo(u)rizing temperature promptly obtains required medicinal extract except that after desolvating.
The preferred medical grade benzinum of described benzinum.
When described medical grade benzinum boiling point is 30 ℃～60 ℃, preferred 10h of extraction time.
When described medical grade benzinum boiling point is 60 ℃～90 ℃, preferred 20h of extraction time.
Wherein, described green tea is bud green tea or dried green tea.
The invention provides the application of a kind of petroleum ether extracted green tea extract in cigarette, be specially: it is 1～10% that petroleum ether extracted green tea extract of the present invention is diluted to concentration with 95% ethanol, adds in the pipe tobacco by 0.01～0.1% of pipe tobacco weight then.
Preferably by pipe tobacco weight 0.05% with the dilution after green tea benzinum extracted extract add in the pipe tobacco.
Preferably the medicinal extract after diluting is added in the pipe tobacco with spray pattern.
The present invention has following beneficial effect:
1, green tea also contains many identical with tobacco or similar fragrance components except that distinctive fragrance component own, adds in the pipe tobacco and can coordinate mutually with tobacco aroma, plays effect abundant, that coordinate cigarette perfume and give the tobacco characteristic perfume;
2, contain free amino acid in the green tea, amino acid can be good at participating in mailland reaction and produces flavor matter in alcoholized tobacco, combustion process, thereby and can in and the alkaline matter in the tobacco reduce and stimulate, enrich cigarette perfume (or spice), reduce and stimulate and assorted gas, improve the mouthfeel pleasant impression;
3, extract and can carry out at ambient temperature with benzinum, do not need heating, extraction process is simple, and is easy and simple to handle, and room temperature condition extracts survivable to heat-labile green tea flavor component down.Adopt the medical grade benzinum can guarantee that medicinal extract meets quality standard, and the green tea extract that extracts can further extract the green tea absolute oil;
4, technology is simple, and is easy and simple to handle, need not to change existing production technology, can significantly improve the cigarette quality.
The specific embodiment
