And S105, packaging the dried dehydrated vegetables in plastic bags, sealing and boxing.
Specific examples of preparing AD hot air-dried vegetables are described in detail below, and specifically include:
a. selecting raw materials. Selecting a vegetable variety with rich meat quality, strictly selecting excellent and inferior vegetables before dehydration, and removing the parts with diseases, pests, rot and shrivelled parts. The ripeness degree should be preferably eight, the vegetables with excessive ripeness or not ripeness should be selected, except removing seeds and pulp of the melon, the other vegetables can be washed with clear water, and then dried in the shade, but not in the sun.
b. Cutting and blanching. And respectively cutting the cleaned raw materials into shapes of slices, threads, strips, blocks and the like according to the requirements of products. When pre-boiling, the raw materials are different, the raw materials are blanched in boiling water which is easy to be thoroughly boiled, the raw materials are slightly boiled in boiling water (the water temperature is generally more than 150 ℃) which is difficult to be thoroughly boiled for a moment, and the blanching time is generally 2-4 minutes. The leaf vegetables are preferably not blanched.
c. And cooling and draining. The precooked vegetables should be immediately cooled (usually by cold water showering) to quickly cool them to room temperature. After cooling, in order to shorten the drying time, a centrifuge can be used for throwing water, or a simple manual method can be used for pressing and draining, after the water is drained, the product can be spread for slightly drying in the sun, and then the product is baked in a preparation tray.
d. And (5) drying. Different temperatures, times, colors and moisture contents during drying are determined according to different varieties. Drying is generally carried out in a drying room. There are roughly three types of drying rooms: the first simple drying room adopts countercurrent blast drying; the second is a drying room combining two layers of double tunnels and forward and reverse flow; the third is a box type stainless steel hot air dryer, the drying temperature range is 65-85 ℃, the drying is carried out at different temperatures, and the temperature is gradually reduced. When the first and second drying rooms are adopted, the vegetables are uniformly spread in the plate and then put on a preset drying rack, the room temperature is kept at about 50 ℃, meanwhile, the vegetables are continuously turned over to accelerate drying, and the drying time is about 5 hours generally.
e. Sorting and packaging. The dehydrated vegetables can be subpackaged in plastic bags after being checked to meet the requirement of food hygiene law, sealed and boxed, and then are marketed.
Referring to fig. 2, the step of preparing the FD freeze-dried dehydrated cauliflower includes:
step S201, collecting freeze-dried and dehydrated vegetable raw materials, wherein yellowing and rotting parts of the leaf vegetable raw materials are manually selected, and rotting parts of the root vegetable raw materials are manually selected.
Step S202, removing soil and impurities on the surface of the freeze-dried and dehydrated vegetable raw material, and removing pesticide residues.
Step S203, peeling the root vegetables.
Step S204, cutting the hot air dried vegetable raw material into a preset shape, and soaking the cut vegetable which is easy to brown into a color protection liquid.
And S205, blanching the hot air dried vegetable raw material which is cut into the preset shape.
And step S206, cooling the hot air dried vegetable raw material after blanching.
And step S207, after cooling, draining the hot-air dried vegetable raw material.
And S208, freezing the drained hot-air dried vegetable raw material.
Step S209, vacuum drying the frozen hot-air dried vegetable material.
And step S210, sorting the hot air dried vegetable raw materials after vacuum drying, removing impurities and other foreign products, accurately weighing according to the packaging requirements, bagging and sealing.
And step S211, packaging the hot air dried vegetable raw materials after the bag is placed.
Specific examples of the preparation of FD freeze-dried dehydrated cauliflower are described in detail below, and specifically include:
a. selecting raw materials. Selecting yellow and rotten parts manually from the leaf vegetables within 24 hours from harvesting to processing; manually selecting the rotten parts of the root vegetables and grading.
b. And (5) cleaning. Removing soil and other impurities on the surface of the vegetables. In order to remove pesticide residues, 1.55 to 1 percent hydrochloric acid solution or 0.05 to 0.1 percent potassium permanganate or 600 mg/kg bleaching powder is generally used for soaking for a plurality of minutes for sterilization and then is rinsed by clean water.
c. And (5) peeling. Root vegetables should be peeled. The consumption rate of chemical alkali liquor peeling raw materials is low, but the export products generally require manual peeling or mechanical peeling, and the peeled raw materials must be immediately put into clear water or color protection liquid to prevent browning.
d. And (5) cutting and forming. The vegetables are cut into certain shapes (granules and slices), and the cut vegetables which are easy to brown are immersed in the color protection liquid.
e. And (6) blanching. Hot water is generally adopted for blanching, the water temperature is changed along with the variety of vegetables and is generally more than 100 ℃; the time varies from a few seconds to a few minutes.
f. And (6) cooling. Immediately after blanching, the product should be cooled (water-cooled or ice-cooled), and the shorter the cooling time, the better.
g. And (6) draining. After cooling, some water drops are retained on the surface of the vegetables, which is not favorable for freezing, and the frozen vegetables are easy to be agglomerated, which is not favorable for next vacuum drying. The method generally adopts a centrifugal drying method.
h. And (4) freezing. The drained materials are quickly and quickly frozen, the freezing temperature is generally below-30 ℃, and the method is ready for next vacuum drying.
i. And (5) drying in vacuum. The vegetables after pre-freezing are put into a vacuum container, the pressure in a window is reduced to be below a three-phase point by virtue of a vacuum system, and a heating system supplies heat to the materials to gradually evaporate the moisture of the materials until the moisture is dried to a moisture end point.
j. And (6) sorting and metering. And immediately sorting the freeze-dried product, removing impurities and other foreign products, accurately weighing according to the packaging requirement, bagging and sealing.
k. And (6) packaging. Vacuum packaging with double-layer plastic bag. The product can be packaged by filling nitrogen because of oxidation browning, and the packaged product is put into an outer carton for warehousing and storage.
Therefore, the preparation method of the brewing type high-fiber low-calorie instant cauliflower rice provided by the invention has the advantages that the process is reasonable, the prepared brewing type high-fiber low-calorie instant cauliflower rice is balanced in nutrition collocation and rich in taste and color, the traditional rice or noodles are replaced by the cauliflower to form staple food, and the cauliflower rice contains 10.8g/100g of dietary fibers; and is essentially all plant dietary fiber. In addition, the FD freeze-dried cauliflower, FD freeze-dried meat and AD hot-dried vegetables are combined, and the color, the fragrance, the taste and the shape of the food material and more than 95% of nutritional ingredients can be reserved after rehydration. The invention is convenient for eating and preparing, and does not need to cut the fresh cauliflower into broken rice by users. The boiled water and the seasoning powder are directly added into the cauliflower rice to be brewed for 6-8 minutes, and then the water is filtered, so that the cauliflower rice is edible.
