Description

一种具有茶香的电子烟雾化剂及其制备方法 An electronic aerosolizing agent and preparation method thereof having tea

技术领域 FIELD

[0001] 本发明属于电子烟雾化剂技术领域,具体涉及一种具有茶香的电子烟雾化剂及其制备方法。 [0001] The present invention belongs to the technical field of electronic aerosol agent, particularly to an electronic aerosol agent and preparation method having the tea.

背景技术 Background technique

[0002] 随着《烟草控制框架公约》的生效实施,世界各国公共场所吸烟禁令范围逐步扩大,国内外烟草消费环境正发生深刻变化。 [0002] With the entry into force "Framework Convention on Tobacco Control," the implementation of the ban on smoking in public places around the world gradually expand the scope, profound changes in the domestic and international environment is undergoing tobacco consumption. 近年来,电子烟呈现快速增长之势,世界电子烟销售总额2010年为9.1亿美元,2011年为12.8亿美元,2012年为18亿美元,2013年超过25亿美元,年均增速高达40%左右。 In recent years, electronic cigarettes showed a rapid growth trend, total world electronic cigarette sales in 2010 were $ 910 million in 2011 to $ 1.28 billion in 2012 to $ 1.8 billion, more than $ 2.5 billion in 2013, an average annual growth rate of up to 40 %about. 其中仅在美国市场,2013年电子烟销售总额已超过10亿美元,比上年增长了近一倍。 Which only in the US market, in 2013 the total sales of electronic cigarette more than $ 1 billion, an increase of nearly doubled over the previous year. 电子烟烟液一般由雾化剂、烟碱和香精调配而成,常用的雾化剂为甘油和丙二醇。 Electronic tobacco typically dispensed by a liquid atomizing agent, nicotine and flavor from, atomizing agent commonly used are glycerol and propylene glycol. 2009年,FDA针对电子烟的研究报道中,对18种NJOY SmokingEverywhere电子烟检测中,发现一种含有二甘醇,这可能是雾化剂中丙二醇所带来的污染物,而二甘醇可引起肾脏及中枢神经损害,人类一次口服致死量约为1.0 mL/kgo虽然甘油无毒,丙二醇为低毒,但是不同等级的丙二醇中所含有的少量污染物对人类健康仍造成威胁。 In 2009, the FDA reported for the electronic cigarette, the smoke detector 18 electronic NJOY SmokingEverywhere found containing diethylene glycol, fogging agent which may be caused by contaminants in propylene glycol, and diethylene glycol may be cause kidney and central nervous system damage, a human oral lethal dose is about 1.0 mL / kgo although non-toxic glycerin, propylene glycol, low toxicity, but a small amount of pollutants in different levels of propylene glycol contained still pose a threat to human health. 因而,降低雾化剂中丙二醇的用量或者开发新型的雾化剂,对于电子烟的发展具有重要意义。 Thus, reducing the amount of propylene glycol aerosol or spray to develop new agents for the development of the electronic cigarette is of great significance.

[0003] 茶叶属茶科茶属植物,乔木或灌木,在我国许多地方广为栽培。 [0003] Tea is a tea division tea plants, trees or shrubs, in many parts of our country widely cultivated. 我国茶类有绿茶、红茶、黄茶、白茶、青茶和黑茶六大类。 Our tea green tea, black tea, yellow tea, white tea, green tea and black tea six categories. 据《茶经》《神农本草经》《本草纲目》记载,茶味至寒,为饮最宜,亦可药用,可生津解渴、提神明目、脱乏解困、清热解毒。 According to the "Shen Nong Ben Cao Jing" and "tea", "Compendium of Materia Medica" records, to flavor cold drink is most appropriate, also pharmaceutically acceptable, may be raw thirst, refreshing eyesight, lack of off predicament, detoxification. 现代医药学研究成果表明,茶叶中含有茶多酚、生物碱、蛋白质、茶色素、有机酸、茶皂苷、维生素及矿物质等多种成分,具有抗氧化、清除自由基、抗炎抑菌、抗辐射、调血脂及提高机体免疫力等作用和功效。 Modern medicine science research shows that tea contains a variety of ingredients polyphenols, alkaloids, proteins, tea pigment, organic acids, tea saponin, vitamins and minerals, has antioxidant, free radical scavenging, anti-inflammatory antibacterial, anti-radiation, lipid regulating and enhancing the immunity action and efficacy. 同时,茶叶提取物也广泛应用于医药、化妆品、保健品及食品添加剂等领域。 Meanwhile, tea extracts are also widely used in medicine, cosmetics, health products and food additives.

[0004]目前,针对茶叶提取物的相关研究较多的关注茶多酚、茶多糖、生物碱的提取,且提取方法多为水提法。 [0004] At present, relevant research on tea extract more attention polyphenols, tea polysaccharide, alkaloids extracted, and the extraction method more for water extraction. 水提法所得浸膏中含有大量的糖类、蛋白质等水溶性成分,具有茶叶特征香的油溶性成分损失较大。 The resulting aqueous formulation containing a large amount of water soluble component sugars, proteins and other extract having characteristic tea aroma oil soluble component losses. 此外,茶叶中含有大量的不饱和脂肪酸以及萜类挥发油成分,这些物质沸点较低,将其添加到电子烟烟弹中,在较低的加热温度下即可雾化,同时还可赋予电子烟茶叶的清香,因而可作为雾化剂使用,从而降低丙二醇和甘油的使用量,并抑制丙二醇的甜腻感。 Further, tea contains large amounts of unsaturated fatty acids and terpenoid volatile oil components, these low-boiling materials, to add it to the electronic tobacco smoke bombs, spray can, while also imparting the electronic cigarette at a lower heating temperature tea fragrance, which can be used as the atomizing agent, thereby reducing the amount of propylene glycol and glycerol, propylene glycol and inhibit sweet feeling.
