Description
技术领域 technical field
本发明属于烟用添加剂制备技术领域，具体涉及一种黑茶精油。同时，本发明还涉及该黑茶精油的制备方法及其在卷烟中的应用。The invention belongs to the technical field of preparation of tobacco additives, in particular to black tea essential oil. At the same time, the invention also relates to a preparation method of the black tea essential oil and its application in cigarettes.
背景技术 Background technique
黑茶是由黑曲菌发酵制成，外表呈黑色。其在发酵过程中会产生一种普诺尔成分，能够起到防止脂肪堆积的作用。每天坚持饮用黑茶，会对抑制腹部脂肪的增加有明显的效果。黑茶的香气总体上属陈香型，根据黑茶香气浓缩物的分析，黑茶中含有在其他茶类中尚未发现的甲氧基苯及其衍生物，这类物质使黑茶香味陈醇，也是黑茶香气味特征的鉴定依据之一。在黑茶中也存在着大量的不饱和萜烯醇类，尤以橙花叔醇最为显著，另外还有丰富的芳樟醇及其氧化物，这些不饱和萜烯醇类在黑茶陈香气味特征中起着十分重要的作用。黑茶中酮类香气物质种类也较多，如6，10，14-三甲基十五烷酮、香叶基丙酮和β-紫罗兰酮等含量也较高。而在黑茶中酸类香气成分却未有捡出，醛类香气成分的含量较少。医学研究表明，用黑茶制取的黑茶精油中含有许多对人体有益的精华，其所挥发出的香气在通过呼吸道进入人体后，能够发挥特殊的保健效果。Black tea is made by fermenting Aspergillus niger and has a black appearance. During the fermentation process, it will produce a Pu Nuoer component, which can prevent fat accumulation. Consistently drinking black tea every day will have a significant effect on inhibiting the increase of abdominal fat. The aroma of dark tea is generally aged. According to the analysis of the aroma concentrate of black tea, dark tea contains methoxybenzene and its derivatives that have not been found in other teas. These substances make the aroma of dark tea mellow , It is also one of the identification basis for the aroma and smell characteristics of dark tea. There are also a large number of unsaturated terpene alcohols in black tea, especially nerolidol is the most significant, and there are also abundant linalool and its oxides. play a very important role in odor characteristics. There are also many types of ketone aroma substances in black tea, such as 6,10,14-trimethylpentadecanone, geranyl acetone and β-ionone, etc. are also high in content. However, acid aroma components have not been picked out in black tea, and the content of aldehyde aroma components is relatively small. Medical research shows that the black tea essential oil made from black tea contains many beneficial essences to the human body, and the aroma it volatilizes can exert a special health care effect after entering the human body through the respiratory tract.
据测定，黑茶中茶多糖含量最高、活性最强，而茶多糖能够降低血糖、血脂，有抗血凝、抗血栓的作用。茶多糖分离后，对其进行体液和细胞免疫的药效实验，结果显示，均有明显增强双相免疫的作用，同时有降低血糖、血清胆固醇及甘油三脂的趋势，这对于老年退化性疾病，如糖尿病、心血管疾病的防治具有重要意义，同时，针对老年人机体抵抗力的下降，也可使其免疫力有所提高。茶多糖对降低血压、减慢心率，增加冠脉流量，延长存活时间(缺氧条件下)，抵抗紫外线、X射线辐射方面具有显著效果。According to the determination, the content of tea polysaccharides in black tea is the highest and the activity is the strongest, and tea polysaccharides can lower blood sugar and blood lipids, and have anti-coagulation and anti-thrombosis effects. After the separation of tea polysaccharides, the efficacy experiments of humoral and cellular immunity were carried out, and the results showed that both of them had the effect of significantly enhancing biphasic immunity, and at the same time had a tendency to lower blood sugar, serum cholesterol and triglycerides, which is beneficial for senile degenerative diseases. , such as the prevention and treatment of diabetes and cardiovascular disease is of great significance. At the same time, it can also improve the immunity of the elderly for the decline of their body resistance. Tea polysaccharides have significant effects on lowering blood pressure, slowing heart rate, increasing coronary flow, prolonging survival time (under hypoxic conditions), and resisting ultraviolet and X-ray radiation.
黑茶中的茶色素有明显的抗菌作用，对心脑血管疾病也有很强的抑制作用。黑茶因采制原料较老，矿质元索含量比其他茶类高，氟对预防龋齿和防治老年骨质疏松有出色效果，硒解刺激免疫蛋白及抗体的产生，增强人体对疾病的抵抗力，并对治疗冠心病、抑制癌细胞的发生和发展有作用。黑茶中富含的茶皂素具有溶血、降胆固醇、抗菌、抗凝活性、镇静活性、抗癌活性和降血压功能。The tea pigment in black tea has obvious antibacterial effect, and also has a strong inhibitory effect on cardiovascular and cerebrovascular diseases. Black tea has a higher mineral element content than other teas due to its older raw materials. Fluorine has excellent effects on preventing dental caries and preventing senile osteoporosis. Selenium solution stimulates the production of immune proteins and antibodies, and enhances the body's resistance to diseases. It also has effects on treating coronary heart disease and inhibiting the occurrence and development of cancer cells. The tea saponin rich in black tea has hemolysis, cholesterol lowering, antibacterial, anticoagulant activity, sedative activity, anticancer activity and blood pressure lowering function.
随着吸烟与健康的问题越来越受到关注，如何提高卷烟的吸食安全性，降低卷烟烟气中的有害成分、提高抽吸的舒适感就成为各卷烟生产企业研发的热点。黑茶所具有的优良特性如果能与卷烟相结合，应该能够很好地解决上述问题，但现有技术中尚未见有相关的报道。As the problems of smoking and health attract more and more attention, how to improve the smoking safety of cigarettes, reduce the harmful components in cigarette smoke, and improve the comfort of smoking have become the research and development hotspots of various cigarette manufacturers. If the excellent properties of black tea can be combined with cigarettes, it should be able to solve the above problems well, but there is no relevant report in the prior art.
