Description
Technical field
The present invention relates to a kind of processing method of the kidney bean that dewaters, belong to food processing technology field.
Background technology
Dehydrated vegetables refers to except a certain amount of moisture preserves the original dried product of learning through hearsay of vegetables as far as possible.The effect of dehydration is the moisture in vegetables is reduced, and improves the concentration of solable matter, suppresses microbial activities, and the activity of the contained enzyme of vegetables itself also is suppressed simultaneously, and product can long preservation.
What the drying application of dewatering vegetable at present was many is heated-air drying dehydration and vacuum freezedrying dehydration, wherein the heated-air drying dewatering process is as follows: 1, raw material is selected: select to have the vegetable variety that enriches meat, excellent roguing be should strictly select before dehydration, ill worm, rotten, shrivelled part rejected.With eighty per cant maturity, be advisable, overdone or not yet done also should choose, and except melon, goes the seed flesh, and the other types vegetables can be rinsed well with clear water, then put in the cool and dry, but should not tan by the sun in the sun.2, cutting, blanching: by the raw material of wash clean according to product requirement cut into slices respectively, the shape such as silk, bar.While precooking, different different because of raw material, easily well-done putting in boiling water scalds, and is difficult for well-done putting in boiling water (water temperature is generally more than 150 ℃) and slightly boils a moment, and generally blanching time is 2～4 minutes.Leaf vegetables preferably not blanching is processed.3, cooling, draining: the vegetables of precooking after processing should carry out cooling (generally adopting the cold water shower) immediately, make it be down to rapidly normal temperature.After cooling, for shortening drying time, available centrifuge water dumping, also available simple hand method is pressed drop, after the water drop is most, just can spread air dry a little out, in order to the sabot baking.4, dry: should determine different temperature, time, color and luster and moisture content while drying according to different cultivars.Dry and generally carry out in drying room.Drying room roughly has three kinds: the simple and easy drying room of the first adopts the adverse current forced air drying; The second is the drying room combined with two layers of twin tunnel, concurrent-countercurrent; The third is van-type stainless steel hot blast dryer, and the bake out temperature scope is 65 ℃-85 ℃, minute different temperatures drying, progressively cooling.While adopting first, second kind of drying room, vegetables are spread equably in dish, then be put on the shelf of establishing in advance, keep 50 ℃ of left and right of room temperature, will constantly stir simultaneously, it is accelerated dry, general drying time is about 5 hours.5, go-on-go, packing: dehydrated vegetables reaches the food hygiene law requirement through check, can be divided in polybag, and be sealed, cases, then listing.
In the preparation technology of dehydrated vegetables, generally all need through high temperature blanching and cold water coolingly, technique is loaded down with trivial details and energy resource consumption is high.
Summary of the invention
The technical problem that the present invention solves is: propose a kind of processing method of the kidney bean that dewaters, the method adopts steam blasting, and technique is simple, energy consumption is low and wholesomeness is good.
