Problems solved by technology

[0006] The most widely used guava product is guava fresh fruit, which has sufficient raw materials, low price, and is not convenient for storage. The young fruit in the production process is usually discarded and cannot be fully utilized. Flavor substances are easily destroyed and the extraction rate of active ingredients is low. At present, guava tea products are mainly limited to primary products such as direct drying and grinding of guava and shredded guava fruit. These products have the following problems: (1) Active ingredients The extraction rate is low, and a large amount of active ingredients are discarded with plant residues, causing serious waste; (2) The solubility of flavor substances and active ingredients is low, and there are few soluble substances, so it is difficult for the human body to effectively absorb and utilize them

(3) Inconvenient to carry and use, not conducive to storage
