Problems solved by technology

However, due to the short storage time of pomelo at room temperature, it is prone to mildew, and it is often necessary to add preservatives such as sodium benzoate to prepare it into tea products, and tea drinks prepared by extracting or squeezing pomelo pulp after crushing pomelo pulp cannot retain pomelo. The original particle shape and flavor of grapefruit, and a large amount of vitamin C will be lost during the preparation process, thereby reducing its nutritional value. These are the key issues restricting the development of pomelo deep-processing products at present.

Embodiment 1

[0032] A kind of processing method of freeze-dried pomelo tea, is characterized in that: specifically comprise the steps:

[0033] 1) Raw material selection: select fresh Guanxi honey pomelo with no cracking fruit, no rot, and a particle size of about 20cm;

[0034] 2) Cleaning: Use a continuous automatic spray cleaning machine to clean the pomelo, and use chlorine dioxide disinfectant with a concentration of 200 ppm to roll and soak the surface of the peel to remove pesticide residues;

[0035] 3) Cutting: the pomelo is cut by quartering automatic continuous cutting machine, that is, the drive motor 4 is started, and the pomelo to be cut is sent from the conical feeding hopper 7 to the feed pipe 1, and the grapefruit is cut by gravity. Falling to the rotary cutting blade 2, the radially distributed rotary cutting blades 2 cut the grapefruit instantly, and the cut grapefruit continues to fall to the sliced ​​grapefruit collection device;

Abstract

The invention belongs to the field of processing of tea products, and particularly provides free-drying grapefruit tea and a processing method thereof. The freeze-drying grapefruit tea product is prepared by selecting fresh grapefruits, cleaning, cutting, peeling, rapidly freezing and hardening, sublimating and drying, and packaging. The free-drying grapefruit tea can effectively retain the nutritional ingredients and aroma components of the grapefruits, after the grapefruit tea is brewed, fruit particles are full and clear, and the original aroma of the grapefruit is emitted, and the grapefruit tea tastes sour and sweet, can be preserved at room temperature for a long time, and has good market prospect.

Description

technical field [0001] The invention belongs to the field of tea product processing, and in particular relates to a freeze-dried pomelo tea and a processing method thereof. Background technique [0002] Grapefruit (Citrus maxima), also known as Wendan, Xiangluan, etc., is the ripe fruit of pomelo, a Rutaceae plant. It has a delicate smell, sweet and sour taste, and rich nutrition. The fruit with therapeutic effects, and the honey citron tea prepared with pomelo as the main raw material is also a health drink highly praised by Japan, South Korea and other countries. However, due to the short storage time of pomelo at room temperature, it is prone to mildew, and it is often necessary to add preservatives such as sodium benzoate to prepare it into tea products, and tea drinks prepared by extracting or squeezing pomelo pulp after crushing pomelo pulp cannot retain pomelo. The original particle shape and flavor of pomelo, and a large amount of vitamin C will be lost during the p...
