preparation example Construction

[0021] The preparation method of the bud tea extract of the present invention comprises pulverizing the bud tea into bud tea powder; extracting and separating the bud tea powder using a CO2 fluid supercritical method to obtain the bud tea extract. Conventional extraction method, the present invention uses supercritical CO2 fluid extraction technology combined with low-temperature centrifugation technology to prepare the bud tea extract without caffeine, which is applicable to a wider range of people, retains the natural and fresh aroma of bud tea to the greatest extent, and has no environmental impact. Harmful solvent generation and discharge, green and pollution-free; and the prepared bud tea flavor has high linalool content (>11.2%), low linalool oxide content (<3.9%), and also contains a variety of small molecules Organic acids, such as acetic acid, isobutyric acid, and isovaleric acid, these low-molecular-weight organic acids can increase fruit and cheese-like aromas, incre...

Embodiment 1

[0025] Weigh 500g of bud tea powder and pulverize it to tea powder, add it into the extraction tank of supercritical CO2 fluid extraction with a CO2 flow rate of 1.0L / h, add 50g of 95% ethanol, and extract at an extraction temperature of 35°C, an extraction pressure of 15MPa and a separation temperature Under the conditions of 35° C. and separation pressure of 7 MPa, extraction and separation were carried out for 1.0 hour to obtain 30 g of bud tea extract 1 with an extraction rate of 6%.

Embodiment 2

[0027] Weigh 500g of bud tea powder and pulverize it to tea powder, add it into a 1000mL supercritical CO2 fluid extraction tank with a CO2 flow rate of 1.0L / h, add 50g of 95% ethanol, and extract at an extraction temperature of 40°C, an extraction pressure of 20MPa and a separation temperature Under the conditions of 35° C. and separation pressure of 8 MPa, extraction and separation were carried out for 1.5 hours to obtain 38 g of bud tea extract 2 with an extraction rate of 7.6%.

Abstract

The invention discloses a preparation method of bud tea extract and application of the bud tea extract in essence and electronic tobacco tar, and the preparation method of the bud tea extract comprises the following steps: crushing bud tea into tea dust, and extracting and separating the bud tea dust by adopting a supercritical method of CO2 fluid to obtain the bud tea extract which does not contain caffeine; the bud tea extract has unique faint scent and can be applied to various beverages and foods; meanwhile, 5-40-fold edible alcohol and 5-40-fold polyhydric alcohol mixed liquid are combined to be applied to traditional tobacco and electronic tobacco tar respectively, and the two application modes highlight the characteristic aroma of bud tea essence and have a certain effect of reducing irritation.

Description

technical field [0001] The invention relates to the technical field of extraction, preparation and application of plants, in particular to a preparation method of tea bud tea extract and its application as tobacco essence in traditional tobacco and electronic cigarette oil. Background technique [0002] Bud tea, also known as spores, grows on Pu'er or Zicuckoo tea trees. Because it germinates before the Spring Festival, it is also called "prime buds". Bud buds are the first batch of Pu-erh tea before the spring tea is picked, and the output is very small, only once a year. Bud bud tea is different from other teas. What comes out is not curly young leaves, but a white bud bag, and the young leaves are hidden in the bud bag. Compared with ordinary green tea, the biggest feature of bud tea is that it has a strong characteristic aroma, sweet fruity aroma, and does not contain caffeine, so it is suitable for a wider range of people. [0003] Supercritical fluid extraction is on...
