But in this processing method, the temperature of steam blanching is as high as 100°C, the temperature range of hot air drying is as high as 80-100°C, and the temperature range of freeze-drying is as low as -15--30°C. The original color of flowers; although it can make up for the shortcomings of high or low temperature to a certain extent by shortening the processing time, the protection of the original color of Camellia japonica flowers is still not ideal

Embodiment 1

[0017] When the weather is fine, pick camellia flowers between 7:00 and 9:00. Camellia flowers are half-opened with buds exposed or fully bloomed, and the buds and petals have no discoloration or damage. After picking, it is used to prepare dried scented tea that maintains the original color of Camellia camellia flowers. The preparation process is as follows:

[0018] 1) Microwave heating: Put the Camellia japonica flowers in a microwave drying oven and heat them 5 times under a microwave power output of 1000w. The heating time is 1 minute, 1 minute, 0.5 minutes, 0.5 minutes and 0.5 minutes, and the moisture content is obtained. It is 14.4% of the original product of dried scented tea; among them, after each heating, the flowers of Camellia camellia are taken out from the microwave drying oven, cooled to 32°C by blowing with a fan, and then the fresh flowers of Camellia camellia after cooling are put back into microwave drying The next heating is carried out in the furnace;

Abstract

The invention discloses a method for preparing dried scented tea which keeps the original color of the fresh golden camellia, comprising the steps of microwave heating and cold-air drying. The microwave heating steps is as follows: putting the fresh golden camellia into a microwave drying furnace, and heating for 4-6 times at the output microwave power of 800-1,200w to obtain the initial product of the dried scented tea, wherein after the fresh golden camellia is heated for 0.5-1 minute each time, the fresh golden camellia is taken out of the microwave drying furnace and cooled to 30-33 DEG C, and then the fresh golden camellia is put in the microwave drying furnace and reheated. The cold-air drying is as follows: taking the initial product of the dried scented tea, and drying the initial product with cold air at 5-15 DEG C until the initial product has the moisture content of 5% or less to obtain the dried scented tea which keeps the original color of the fresh golden camellia. The dried scented tea prepared by adopting the method effectively keeps the original color of the fresh golden camellia and has higher quality.

Description

technical field [0001] The invention relates to the technical field of flower processing, in particular to a method for preparing dried scented tea that maintains the original color of Camellia camellia flowers.
