Industrialized jasmine tea processing method

Abstract

The invention discloses an industrialized jasmine tea processing method. The industrialized jasmine tea processing method adopting a sectional industrialized technical process includes: jasmine fragrance release with temperature, humidity and air controlled, fragrance gathering by means of negative-pressure air suction and activated carbon adsorption, and subcritical extraction of initial essential oil and flower residue essential oil (in a first blossom stage); tea leaf fragrance adsorption with essential oil temperature controlled, constant-temperature hermetic fragrance curing and low-temperature drying (in a second non-blossom stage). The industrialized jasmine tea processing method has the advantages that automatic and precise control of a jasmine fragrance release environment is realized, and fragrance release time is prolonged; effectiveness in collection of fragrant substances is realized by means of fragrance adsorptive gathering techniques, and owing to subcritical extraction, essential oil quality is improved, and industrial production is facilitated; by means of 'jasmine essential oil-tea' scenting, a traditional scenting mode of mixture of jasmine flowers and tea leaves is broken, possibility of production of scented tea in non-blossom seasons is realized, and automation and industrialization in production of scented tea are realized.

Description

technical field

[0001] The invention belongs to the field of scented tea preparation, and in particular relates to a method for industrialized processing of jasmine tea. Background technique

[0002] Jasmine, belonging to the genus Jasmine of Oleaceae, is native to India and Arabia. It was introduced into my country from the Han Dynasty and has a history of more than 1,700 years. In 2013, my country's jasmine planting area was about 190,000 mu, with an annual output of about 110,000 tons of flowers. The main production areas are in Guangxi, Fujian, Yunnan, Sichuan and other places. It is mainly used for scenting scented tea, with a total output of about 85,000 tons.
