Problems solved by technology

[0004] The Chinese patent application with the application number 200710148634.1 discloses a processing method of Camellia japonica scented tea. First, the flowers are steamed and then dried. Although the color of the flowers can be basically maintained, the flowers will be deformed and shrunk when they are blanched. , or even discoloration. In addition, the drying environment is not carried out under vacuum conditions. The polyphenols contained in Camellia japonica will react with oxygen, causing the color of the flower to brown, so this method still cannot solve the problem caused by the drying process of flowers. Shrinkage, Discoloration Problems
The Chinese patent application with the application number 201310202173.7 discloses a processing method of Camellia japonica flower tea. First, because the water content of the flowers after the first vacuum drying is high, reaching 20-25%, it is difficult to maintain the original shape, and it is easy to change color; Secondly, the second vacuum drying is used, and the operation is a bit cumbersome; thirdly, the optimal power of microwave baking changes sensitively with the residual amount of free water, and a slight deviation may easily cause caramelization of the flower core
The Chinese patent application with the application number 201410153473.5 discloses a drying method that can keep the bright color, blooming shape and inherent fragrance of Camellia camellia. It is to pre-freeze the flowers of Camellia camellia at a temperature below -18°C, and then store them in a vacuum freezer. The entire drying process is completed under the condition of 45-70°C. Although the bright color, blooming shape and inh

Abstract

The invention discloses a processing method of curled golden camellia. The processing method comprises the following technological steps: (1) preparation of materials; (2) pre-freezing and shaping of fresh flowers; (3) vacuum freeze-drying; and (4) dehydration, deactivation and flavoring. According to the method, fine parameter control is implemented during the vacuum freeze-drying process, the rate of finished products is high and the operation is simple. The curled golden camellia produced by the method disclosed by the invention has the advantage of retaining the shape and color of fresh flower type golden camellia; the soaking method is simplified; the caffeine is extremely high in water solubility; the flavor comes out rapidly; the curled golden camellia is full of heavy golden camellia flavor and green grass flavor and is free of bitter taste; total nutrients of the flowers are retained as far as possible, so the curled golden camellia is higher in health care value and the economic efficiency of the golden camellia flowers is remarkably improved.
