Abstract
The present invention relates to the storage and freshness-retaining technology field.
It is abundant that the present invention makes full use of China's water resource, utilizes that temperature is low and stable under water, and the good storage environment of high pressure hypoxemia is sealed in fresh-keeping fruit in the nontoxic fluid-tight packaging material, deposits in 1-40 rice depths under water.Have need not build the storehouse, not account for the soil, the source of not consuming energy, suppress germ and grow outstanding advantage such as good refreshing effect.
Description
The present invention relates to the storage and freshness-retaining technology field.
The existing fruit storage and freshness-retaining technology of China mainly contains refrigeration, controlled atmosphere and various local method storage.Refrigeration, controlled atmosphere has good fresh-keeping effect to most of fruit, but build storehouse expense height, energy consumption is big, cost is high, various local method storage technology is easy and simple to handle, cost is low, but is subjected to the various places environmental influence big, fresh-keeping effect is not ideal enough.The existing fruit storage capacity of China is about about 10% of output, because the keeping-freshness storage scarce capacity, annual fruit rots to lose and accounts for more than 20% of total output.
Process for keeping fresh fruit stored underwater is to utilize that temperature under water is low and stable, the good condition of high pressure hypoxemia, a kind of brand-new energy-saving fresh-keeping technology of storage fruit.Have need not build the storehouse, not account for the soil, the source of not consuming energy, suppress that sick worm grows, cost low (compare underwater fresh-keeping with refrigeration, controlled atmosphere, per ten thousand jin of storage capacity can be saved and build the storehouse and invest 10,000 yuan, but every month saves energy 2000 degree.Per ten thousand jin of storage periods can reduce by 1000 yuan of storage costs), effective (the decayed fruit rate is 0-3%, only with refrigeration or ca cold storage 50%) etc. outstanding advantage.All have the place (reservoir, river, river, lake, sea, pond, well etc.) at water source to adopt.
This fruit storage and freshness-retaining technology to the effect that with anosis worm, the fruit that has no mechanical damage, after giving processing reduction fruit temperature, place fluid-tight non-toxic packaging materials, deposit in 1_40 rice depths under water according to different fruit and shelf time length, the best storage degree of depth is a 5-15 rice.Packaging material that sealing fruit is used and the container size that holds packaging material are selected voluntarily according to reserves.In each packaging material, put into the calcium hydroxide of fruit weight 0.5-5%, or the sodium peroxide of fruit weight 0.5-5%, calper calcium peroxide and the porous material (vermiculite, queen closer etc.) etc. that fully absorbs saturated liquor potassic permanganate are made gas regulator, sealing then.Gas regulator need be contained in softness and the ventilative material (gauze, cotton balls etc.), can protect normally carrying out of positive control, also can prevent damaged fruit.
The present invention is applied widely, and is easy to operate, promptly is fit to large-scale commercial storage fruit, also is applicable to a spot of keeping-freshness storage of peasant household, and its hoarding effect obviously is better than conventional preservation method.
Fruit underwater sealing packing is shown in Figure of description.1 is the rope that lifting, fixed container are used among the figure; 2 is that plastics, stainless steel, aluminium, pottery, glass etc. are nontoxic, water insoluble, not with the metal of water reaction, nonmetal or container containing that synthetic material is made; 3 is the internal layer sealing and packing material; 4 is gas regulator; 5 is fresh-keeping fruit.
Claims (4)
1, a kind of fruit is sealed in the non-toxic packaging materials, is stored in the nature fresh fruit and energy-saving technology of (river, river, lake, sea, reservoir, pond, well etc. are under water) under water, it is characterized in that the fruit sealing is placed under water.
2, according to the described fruit freshness preserving technology of claim 1, it is characterized in that storing the depth of water is 1-40 rice, and the best storage degree of depth is a 5-15 rice.
3, according to the described fruit freshness preserving technology of claim 1, it is characterized in that the non-toxic packaging materials of using be plastics, stainless steel, aluminium, pottery, glass etc. water insoluble, not with no noxious metals, the nonmetal or synthetic material of water reaction.
4, according to claim 1,2,3 pairs of fruit that are sealed in the packaging material, take to improve the measure of storage environmental gas composition, it is characterized in that selecting for use calcium hydroxide, calper calcium peroxide, potassium permanganate etc. to make gas regulator according to the kind of storage fruit, the length of shelf time.
