Abstract
The present invention is a kind of Flesh-keeping film (bag), it mainly by the additives such as property , potassium permanganate, silicon-dioxide, medical stone of living with a certain amount of high-pressure polyethylene, after mixing stirring, mixing in mixing roll, granulation in granulation, and make masterbatch, and then mix stirring with a certain amount of high-pressure polyethylene, carry out blown film.Be characterized in: ventilative, saturating wet, absorption property is good, and long fresh-keeping period is 0-35 ℃ in temperature, during wetness 85-95%, and fruits and vegetables class freshness-retained 7 days-3 months.
Description
The present invention is the high score subclass.
In China summer, because the sweltering heat of weather causes rotting of vegetables, fruit, grain is infested to go mouldy, and promptly causes the financial loss of more than one hundred million units to country, has caused pollution to urban environment again.So this problem of freshness date that prolongs vegetables, fruit is more and more extremely paid attention to.
242 pages of China's technological achievement complete works of 90 years the 1st phases, the mineral additive preservative film of Liaoyuan City plastic institute development, it is to adopt mineral additive to replace chemical preservative, select for use appropriate resin and auxiliary agent to process, this technological achievement, though play certain freshening effect, because the bad freshness date that makes of its adsorption effect has only 2-3 days.
Task of the present invention is at the problems referred to above, provides a kind of air-moisture-permeable, absorption property good, and fresh-keeping fruit and vegetable can be more than 7 days, and grain can be at the Flesh-keeping film (bag) more than 2 years.
Fruits and vegetables rot to be what the reason by following four aspects caused:
1, respiration under the katalysis of a series of enzymes, the material of the more complicated that exists in the cell, as starch, sugar and organic acid, progressively is decomposed into carbonic acid gas and water, and breathes out by fruit and vegetable surfaces, and consumed energy causes fruits and vegetables to take a stand and rots.2, transpiration still to the rising moisture content in the external world, causes the Ordinary Wear and Tear of its weight after fruits and vegetables are gathered, can not be replenished from the external world by rising moisture content, along with the moisture content transpiration, cell reduces again, cause fruits and vegetables to be wilted gradually, general fruits and vegetables moisture content loses at 5% o'clock and wilted condition will occur.3, the effect of second diluted gas, the fruits and vegetables after gathering give off carbon dioxide and water in, exhalation second diluted gas, and the second diluted gas has been a dematuration has quickened wearing out of fruits and vegetables, this is septic principal element.4, microorganism, rotten fungus, the microbiological attack before and after plucking can impel fruits and vegetables mouldy, corrupt.
The present invention is the infested particular case of going mouldy of physiology, pathological characteristic and the grain according to postharvest fruit and vegetable, creates the environment of an adaptation, continues to keep normal minimum respiration, prevents disease, reduces loss, reaches the purpose of keeping-freshness storage.Be characterized in:
1, ventilative, water vapour permeability is good, in order to suppress the eupnea of fruits and vegetables, delays its metabolism, makes the CO in the bag
2And O
2A suitable gaseous state ratio is arranged, improve CO
2Concentration, play restraining effect, reduce O
2, keep the nutrient supply of cells survival.
2, the adsorptivity of obnoxious flavour is exactly the absorption to the second diluted gas specifically, and gets rid of outside bag, slows down the fruits and vegetables speed of accelerating the ripening.
3, fog dispersal property after the fruits and vegetables pack is sealed, because exhalation moisture content causes bag interior dewfall or has ponding to soak, also can be quickened rotting of fruits and vegetables, the unnecessary moisture content in the bag can be excreted.
4, inhibition because the intravital gas concentration lwevel height of bag all has the effect that holds back the development to various rotten fungus, can mix some chemical bactericides, sterilant, mould inhibitor, sanitas to some discrete kinds at different bacterium in addition in auxiliary agent.
5, adjustability, above-mentioned various performances all can be aligned according to different varieties and be adapted to the different rare absorption of respiratory intensity, second, fog dispersal performance, bactericidal property, sterilization worm performance etc.
6, long fresh-keeping period is 0-35 ℃ in temperature, during wetness 85-95%, and fruits and vegetables class freshness-retained 7 days-3 months, in thermostatic chamber, when temperature is controlled at 2-10 ℃, freshness-retained 4-6 month.Rice Vermins-proof mildew-proof storage was more than 2 years.
Task of the present invention is finished by following technology.
Batching-masterbatch making-mixing blown film.
A, batching: activated carbon 1-20% is 3-5% particularly, and granularity is at the 200-250 order, the adsorbable 500-1000m of every gram
2Potassium permanganate 1-10%, 1-3% particularly, granularity should be higher than the granularity of activated carbon at the 250-350 order, and it is rare mainly to adsorb second, silica 1-20%, 1-4% particularly, granularity 180-350 order plays ventilative in film, saturating wet effect, medical stone 1-10%, particularly 3-6% can discharge VITAMIN and mineral substance favourable to fruits and vegetables more than 18 kinds, sterilant 0.1-0.9% in preservation process, particularly 0.8%, fragrant burnt, Citrus biphenyl, the adjacent benzene of lauryl aldehyde, vegetables, base phenol, the Zhong Ding ammonium, indolylacetic acid, naphthyl acid, choline dichloride, sterilant 0-30%(is piperonyl fourth 0-15% wherein, zanthoxylum powder 0-15%), high pressure polyethylene or low pressure polyethylene, linear polyethylene 30-85%, particularly 40-50%.
B, masterbatch are made, and after the material thorough mixing for preparing was stirred, the input mixing roll carried out mixing, and then drops in the tablets press and carry out granulation, and masterbatch is made.
C, mixing blown film, with high pressure polyethylene or low pressure polyethylene, linear polyethylene and masterbatch carried out thorough mixing by 100: 20 and stir, and dropped into forcing machine again and carried out blown film.
Embodiment:
A, fruits and vegetables batching: activated carbon 3-5%, potassium permanganate 1-3%, medical stone are 3-6%, silica 1-4%, sterilant 0.8%, high pressure polyethylene 40-50%.
B, grain batching: sterilant 15-25%(is piperonyl fourth 7-12% wherein, zanthoxylum powder 8-13%), high pressure polyethylene 75-85%.
