Problems solved by technology

[0005] The Pu-erh tea essential oil extracted by the traditional steam atmospheric distillation method is a volatile substance with a small molecular weight and a low boiling point, such as α-terpineol, geraniol, 1,2,3-trimethoxybenzene , β-terpineol and epoxy linalool, etc., but the volatile substances with larger molecular weight and higher boiling point, such as palmitic acid (palmitic acid), etc., cannot be obtained
At present, there is no report on extracting high boiling point essential oil from Puer tea

Abstract

The invention discloses a Pu-erh tea essential oil and a preparation method thereof. The Pu-erh tea essential oil is an oily liquid which is obtained by performing vapor reduced pressure distillation and extraction on Pu-erh tea. The preparation method comprises the following steps: (1) mixing Pu-erh tea and water according to a mass ratio of 1:1, and putting into a reduced pressure tank; (2) heating to 90-100 DEG C; (3) vacuumizing until the pressure intensity is reduced to 60-80 KPa; (4) collecting fractions; and (5) performing water-oil separation on the fractions cooled to room temperature, and extracting the oily liquid. The Pu-erh tea essential oil prepared by the invention has a big molecular weight and a high boiling point, and has unique fragrance and an antibacterial effect.

Description

[0001] Technical field: [0002] The invention relates to the technical field of preparation of essential oils, in particular to a Pu'er tea essential oil. Background technique: [0003] Pu-erh tea is a unique local famous tea in Yunnan. According to different processing methods, Pu-erh tea is divided into naturally fermented raw tea and cooked tea artificially fermented by controlling temperature and humidity. Due to the special geographical environment, processing methods, raw materials and other factors, Pu-erh tea is different from ordinary green tea, green tea and black tea in aroma, taste and soup color. Not only that, Pu'er tea also has the effects of lowering cholesterol, blood sugar and blood lipids, losing weight and sobering up. [0004] Pu'er tea contains a large amount of volatile substances, most of which are alcohols, aldehydes, ketones, and esters, such as epoxy linalool, linalool, β-ionone, dihydroactinolactone, trans-geranyl Acetone, citronellal, mushroo...
