Abstract
The invention discloses a preparation technology of patrinia villosa (simplified as sowthistle) as dual-use products of tea and food. The preparation technology of the patrinia villosa as the dual-use products of tea and food comprises the following step: (1), selecting materials; (2), deactivating enzymes; (3), performing spread-cooling and dewatering; (4), performing drawing air for dehydrating; (5), regaining moisture; (6), cutting the moisture-regained materials into short sections for shaping; (7), rolling the shaped short sections; (8) performing drying; and (9) performing packaging. The patrinia villosa is utilized as the raw material of the preparation technology, and the raw material is processed into tea-shaped products by the following technologies: selecting materials, deactivating enzymes with boiling water, dewatering the enzyme-deactivated material, performing drawing air for dehydrating, cutting the dehydrated material into short sections for shaping, rolling the shaped short sections, performing drying and so on, so that a product which can be used as a tea (used for brewing tea) and a food (used for making sowthistle soup) is prepared. The preparation technology solves the problems of difficult storage and transportation of the sowthistle caused by high water content, so that the sowthistle can be eaten in all seasons; moreover, the preparation technology preserves functional ingredients of the sowthistle which are beneficial for human health, so that the healthcare functions of the sowthistle are brought into play, and popularization of the healthcare effects of the sowthistle are promoted. The preparation technology realizes large-scale industrial processing of the sowthistle.
Description
technical field [0001] The invention relates to the technical field of tea production, in particular to a production process of a dual-purpose product of Baihuabaipianjiang, tea and food. Background technique [0002] Baihuabaibai is a perennial herbaceous plant of the genus Patrinia in the family Valerianaceae. It is widely distributed in my country.
