Embodiment Construction

[0016] The following is a detailed introduction to the freeze-drying process of papaya with smooth skin, and a detailed description of the relevant technical conditions of the process, which has certain guiding significance for the implementation of freeze-drying production.

[0017] 1. Test materials and methods

[0018] 1.1 Principle of vacuum freeze-drying technology

[0019] Vacuum freeze-drying is the drying of material moisture under freezing, that is, direct sublimation from ice crystals to water vapor. Therefore, freeze-drying is also called sublimation drying.

[0020] When drying, the material should be frozen first, and then it can be dried in a high vacuum chamber. However, if the moisture of the material is to be evaporated directly from the ice crystal or water vapor, the temperature of the aqueous solution in the material must be kept below the triple point. As shown in Figure 1, the three phases of solid, liquid, and gas coexist or are at a point of equilibriu...

Abstract

The invention provides a method for preparing pawpaw freeze-drying powder, comprising pretreatment, refrigerating, drying, decomposing, drying, and breaking, for resolving the problems as long-time fresh holding, storage, and deep treatment. The inventive produce has special physical property, better solubility, high activity, and held color, taste and smell or pawpaw, to be used as main materials of following deep treatment.

Description

technical field [0001] The invention relates to a method for processing papaya with vacuum freeze-sublimation drying technology and superfine pulverization and wall breaking technology. Background technique [0002] Papaya (Chacnqmeles Sinensisc Thouin kotne) belongs to Rosaceae deciduous shrubs or small trees, and is cultivated in Shandong, Shaanxi, Anhui, Jiangxi, Hubei and other provinces in my country. After the fruit is dried, the peel is smooth and does not shrink, so it is called light-skinned papaya. Modern pharmacological research shows that papaya contains carbohydrates, proteins, fats, minerals, vitamins A, D, Vc, V E And carotene, carotene, fruit acid, saponin, papain and papain, papain has a strong anti-cancer activity against lymphatic leukemia cells, and oleanolic acid has a special effect of protecting the liver. The latest research shows that papaya can also enhance the body's resistance and help the prevention and treatment of atypical pneumonia and the r...
