Embodiment 1

[0040] An embodiment of the preparation method and application of pomelo freeze-drying described in the present invention, the preparation described in this embodiment is the preparation of freeze-drying the whole pomelo fruit, which is prepared by the following method:

[0041] (1) Pre-treatment: select pomelo fruits with a diameter of 3 to 7 cm, remove impurities, divide them into two groups after cleaning, and perform penetrating piercing and centrally symmetrical semi-piercing piercing respectively;

[0042] (2) Pre-freezing: place the pre-treated pomelo fruit in the freezer, freeze to -35°C for 8 to 12 hours, and keep freezing for 2 hours;

[0043] (3) Freeze drying: put the pre-frozen pomelo fruit in a vacuum freeze dryer, the temperature of the cold trap is -35°C ~ -40°C, the vacuum degree of the drying chamber is 40Pa, and the temperature of the heating plate is set at 50°C until the material temperature The curve is parallel to the temperature curve of the heating pla...

Embodiment 2

[0047] An embodiment of the preparation method and application of pomelo freeze-drying described in the present invention, the preparation of the whole pomelo fruit described in this embodiment is prepared by the following method:

[0048] (1) Pre-treatment: select pomelo fruits with a diameter of 3 to 7 cm, remove impurities, and perform penetrating piercing after cleaning;

[0049] (2) Pre-freezing: place the pre-treated pomelo fruit in a freezer, freeze to -35°C for 4 to 8 hours, and keep freezing for 4 hours;

[0050] (3) Freeze drying: put the pre-frozen pomelo fruit in a vacuum freeze dryer, the temperature of the cold trap is -35°C ~ -40°C, the vacuum degree of the drying chamber is 40Pa, and the temperature of the heating plate is set at 50°C until the material temperature The curve is parallel to the temperature curve of the heating plate, and the freeze-drying ends;

Abstract

The invention discloses a freezing and drying preparation method and application of pomelo fruits. The preparation method comprises the step that pretreated pomelo fruits are frozen and dried, wherein the pomelo fruits which need to be molded are molded when being dried into semi-dried products, and continuously frozen and dried till the water content is lower than 8%. By adoption of the preparation method, the defects that a traditional processing method is long in production period and high in cost are overcome, the production efficiency is improved, the production cost is lowered, meanwhile, losses of effective components of a medical material are reduced, dried products subjected to freezing and drying are uniform in appearance color, attractive, easy to cut and prepare and convenient to use, and the quality stability of freezing and drying is improved; and the pomelo fruits prepared through the preparation method can be intact, or be cut in halves, or cut and prepared into slices or blocks or shreds, or smashed to use.

Description

technical field [0001] The invention relates to the field of processing Chinese medicinal materials, in particular to a preparation method and application of pomelo fruit. Background technique [0002] Pomelo fruit is the dry immature fruit of Citrus grandis (L.) Osbeck and its variants of the Rutaceae plant. Harvest when the fruit is 3-7cm from March to April. Wash well, cut into two halves or slices, and dry in the sun or at low temperature. It has the effects of drying dampness and reducing phlegm, widening the middle and promoting qi, and eliminating food. It is used for wind-cold cough, itchy throat with excessive phlegm, depression of qi and chest tightness, food accumulation and alcohol, cold and pain in the abdomen, nausea and diarrhea. The aliases of pomelo include Lei pomelo, pomelo, hukan, stinky orange, stinky pomelo, Xiangluan, bar, throw, Wendan, orange red pearl, and orange red tire. There are many varieties of pomelo, the most common varieties are: ①Citrus...
