Embodiment Construction

[0039] A kind of preparation method of mountain grape freeze-dried fruit powder, concrete implementation steps are as follows:

[0040] (1) material selection

[0041] Select more than 90% maturity of mountain grapes, and select fresh, non-rotten, and sundry-free mountain grapes as raw materials.

[0042] (2) cleaning

[0043] Rinse the surface with clean water to remove dust and finally rinse it off with high pressure water.

[0044] (3) Color protection

[0045] The cleaned grapes are protected at room temperature with a mass fraction of 0.5% zinc acetate aqueous solution and a 0.3% mass fraction of ascorbic acid aqueous solution, and the color protection time is 30 minutes;

[0046] (4) Dehardening, denucleation and refining

[0047] After the mountain grapes are washed, they are sent to the crusher for crushing, and the fruit stems are discharged, and the grape pulp is separated through a filter. If the fruit stems are mixed in, a large amount of tannins will be disso...

Abstract

The invention relates to a preparation process of fruit powder and provides a preparation method for freeze-drying vitis amurensis fruit powder. The freeze-drying vitis amurensis fruit powder is prepared by processes of (1) selecting materials, (2) washing, (3) protecting the color, (4) removing hard parts and removing kernels, and grinding, (5) heating for softening, (6) squeezing, (7) concentrating, (8) pre-freezing, (9) freezing and drying, (10) crushing, (11) packaging in vacuum, (12) sterilizing and the like. According to the preparation method, a low-temperature vacuum drying technology is adopted to prevent an enzymatic browning reaction well and preserving purpurin in grapes; the product is purple. The preparation method has the advantages of simple process, convenience in operation, low production cost and the like and is suitable for industrial production.

Description

technical field [0001] The invention relates to a preparation process of fruit powder, that is, a preparation method of mountain grape freeze-dried fruit powder. Background technique [0002] Vitis vinifera is the most cold-resistant species in the genus Vitis. The branches and vines can withstand low temperatures of -45°C, and the roots can withstand low temperatures of -14--16°C. It is the main germplasm resource for cold-resistant grape breeding at home and abroad. Grape juice has long been hailed by scientists as "vegetable milk." Most of the sugar in grape juice is easily absorbed by the body. Drinking more grape juice can strengthen the spleen and stomach, and it contains more tartaric acid, which can help digestion. Grape juice is also the best drink for patients with inflammation, and it has an auxiliary effect on the rehabilitation of frail patients, arteriosclerosis and nephritis patients. Although the production of mountain grapes is large, the products current...
