Embodiment 1

[0017] Remove surface sediment from fresh carrots without rot and pests, soak them in 0.05% potassium permanganate for 3-5 minutes to remove residual pesticides on the surface, rinse them with clean water several times, and rinse them with 1%-2% sodium hydroxide at room temperature or Treat in boiling water for 5-10 minutes to remove the epidermis, rinse with clean water and cut into cubes (cross-sectional area is 0.3cm×0.5cm, length less than 4cm), blanched in boiling water for 5 minutes, immediately rinse with cold water and cool to room temperature after taking it out. After draining the surface moisture, put it on a plate, pre-freeze in a refrigerator at -10--50°C for 3-5 hours, take it out and dry it in a freeze dryer for 6-12 hours, and the moisture content in the raw materials will drop to 6-7%.

Embodiment 2

[0019] Remove the surface sediment from the fresh peppers, soak them in 0.05% potassium permanganate for 3-5 minutes to remove the residual pesticides on the surface, rinse them with clean water several times, cut them into slices (3cm×3cm), and blanch them in boiling water for 2-3 minutes After taking it out, immediately rinse it with cold water and cool it to room temperature, drain the surface moisture and put it on a plate, pre-freeze it in a refrigerator at -10-50°C for 3-5 hours, take it out and dry it in a freeze dryer for 6-12 hours, The moisture content in the raw material is reduced to 6-7%, and the dehydrated vegetable bag is obtained by sorting and packaging.

Embodiment 3

[0021] Wash the fresh cabbage, peel off the leaves and cut into slices (3cm×3cm), blanching in boiling water for 1-2 minutes, immediately rinse with cold water and cool to room temperature, drain the surface water and place on a plate Pre-freeze in a refrigerator at -10--50°C for 3-5 hours, take it out and dry it in a freeze dryer for 6-12 hours, the moisture content in the raw materials will drop to 6-7%, and then separate and pack to make dehydrated vegetables Bag.

Abstract

The invention discloses a method for preparing dehydrated vegetable rools, which is characterized by comprising the steps of material selection, washing, cutting, precooking, cooling, drying, separate checking and packaging. The method has the advantages that: due to the adoption of the precooking, the activity of enzymes in vegetables can be inhibited, nutrient loss can be prevented in a post-production process, the sterilization effect can be achieved, and the original color, aroma and taste of the vegetables can be kept; and the dehydrated vegetables prepared by vacuum freeze drying comprise porous tissues and have high rehydration performance.

Description

technical field [0001] The invention relates to a preparation method of dehydrated vegetable bag. Background technique [0002] Vegetables are one of the essential foods in people's daily diet. Vegetables can provide a variety of vitamins and minerals necessary for the human body. 90% of vitamin C and 60% of vitamin A are from vegetables. Studies have found that many vitamins, minerals, trace elements and related phytochemicals, enzymes, etc. in vegetables are effective antioxidants, so vegetables are not only low-sugar, low-salt, low-fat healthy food, but also can effectively reduce environmental pollution. Pollution damages the human body, and vegetables also play a preventive role in various diseases. [0003] Fast-paced life and work style lead to unreasonable eating habits. In the face of heavy study and work pressure, people need to fill their stomachs conveniently and quickly. High-fat, high-calorie convenience food becomes the daily dietary requirement. People'...
