Method for preparing Senmiao jinziguan Xanthoceras sorbifolium Bunge scented tea through vacuum freeze drying

Abstract

The invention discloses a method for preparing Senmiao jinziguan Xanthoceras sorbifolium Bunge scented tea through vacuum freeze drying, and belongs to the technical field of scented tea preparation. The method for preparing Senmiao jinziguan Xanthoceras sorbifolium Bunge scented tea through vacuum freeze drying comprises the following steps: (1) selecting raw materials: picking fresh flowers of the Senmiao jinziguan Xanthoceras sorbifolium Bunge in the initial blooming period, and removing soil and impurities on the flowers of the Senmiao jinziguan Xanthoceras sorbifolium Bunge; (2) pre-freezing: placing the flowers of the Senmiao jinziguan Xanthoceras sorbifolium Bunge for 6 hours at the temperature of-30 DEG C, and carrying out pre-freezing; (3) vacuum freeze-drying: putting the pre-frozen flowers into a freeze-drying bin, and controlling the vacuum degree to be 50-60Pa, the sublimation temperature to be-10 DEG C for 14 hours and the desorption temperature to be 28 DEG C for 6 hours; (4) screening: removing disintegrating slag in the treated dried flowers of Senmiao jinziguan Xanthoceras sorbifolium Bunge; and (5) metering and sub-packaging: sorting the dried flowers of Senmiao jinziguan Xanthoceras sorbifolium Bunge, and carrying out metering and sub-packaging. The adopted drying temperature is low, the tissue, appearance and nutritional ingredients of the petals cannot be damaged, and the prepared xanthoceras sorbifolia bunge scented tea is fresh and mellow in fragrance, good in rehydration performance and relatively complete in nutritional ingredient retention.

Description

technical field

[0001] The invention relates to a method for preparing Senmiao Jinziguan Xingguan fruit scented tea by vacuum freeze-drying. Background technique

[0002] Xingguan fruit is a woody oil-bearing and medicinal tree species unique to the cold to warm temperate xerophytic regions in northern my country. The fruit, flowers, leaves, stems, and roots of X. sorbifolium all contain bioactive ingredients that can improve body functions. The linoleic acid and linolenic acid in Xantho sorbifolium seed kernels are rich in linoleic acid and linolenic acid, and regular consumption can prevent cardiovascular and cerebrovascular diseases; cholesterol etc. The water extract of the kernels, stalks and leaves of X. sorbifolium has a significant effect on enuresis in children, and can antagonize the learning and memory impairment in mice caused by chemical drugs.
