Abstract
The fruit and vegetable preserving method incldues the following steps: selection of fruit and vegetable; packing fruit and vegetable into air regulating silicon window packing with certain ventilating performance after being let cooled; and storing the packed fruit and vegetable at proper temperature and humidity. The present invention can result in high preserving effect at relatively low cost and may be used widely in preserving various fruit and vegetable.
Description
The present invention relates to a kind of fruit and vegetable preserving method with air regulating silicon window, can be widely used in the storage fresh-keeping process of fruit, vegetables.
Existing fruit, the common storage procedures of vegetables, period of storage is short, keeping cost height, loss is big, and fresh-keeping effect is poor.
The object of the present invention is to provide that a kind of storage procedures is simple, cost is low, the fruit and vegetable preserving method with air regulating silicon window of small investment, long fresh-keeping period, good refreshing effect, remarkable in economical benefits.
In order to reach the foregoing invention purpose, fruit and vegetable preserving method with air regulating silicon window of the present invention comprises the steps:
(1) chooses good fruit, vegetables;
(2) go into before the storage air regulating silicon window external packing that will have certain air permeability through the osed top of packing into after the pre-heat radiation;
(3) the air regulating silicon window external packing that fruit, vegetables will be housed is put under the suitable temperature and humidity and preserves.
Fruit and vegetable preserving method with air regulating silicon window of the present invention, its fresh keeping principle is: with High molecular material---silica gel is coated on the suitable fabric of density, as the transom of fresh-keeping external packing.By the good ventilative ratio of silica gel, make pernicious gases such as fruits and vegetables discharge in the external packing carbon dioxide, ethene see through the silicon window and distribute; Outside air can infiltrate in the external packing simultaneously, replenishes fruits and vegetables and breathes the oxygen that is consumed.The airing function of silicon window can automatically adjust carbon dioxide in the external packing and concentration of oxygen ratio like this, thereby keep suitable combination of gases, to reach the fruits and vegetables respiratory metabolism, reduce enzymatic activity, to delay senility, alleviate the purpose of fruit and vegetable physiological regulation disease and pest and drying loss, prolonged the preserving fruit and vegetable utilizing phase greatly.
Fruit and vegetable preserving method with air regulating silicon window of the present invention, fruits and vegetables can be placed in ventilation warehouse, trench, the simple and easy environment in earth kiln hole, but the fresh-keeping effect under the low temperature that suits in freezer is stronger.
Fruit and vegetable preserving method with air regulating silicon window of the present invention, said silicon window have mainly used a kind of purpose made silastic fabric base film, and this film adopts condensed room temperature vulcanized silicone rubber to make, and its raw MAT'L source is sufficient, and cost is lower.This film has certain permeability to air and ventilative ratio to gases such as oxygen and carbon dioxide.With a certain size this film as the gas diffusion window, it is alleged silicon window, be embedded in a certain size the sealing external packing, can pass through silicon window automatically regulating external packing composition of gases within, make fruit vegetables storing in the environment of a kind of suitable minimizing oxygen and increase carbon dioxide, thereby reduce fruits respiratory intensity, delaying senility course reaches purpose fresh-keeping and that prolong storage period.The experiment proved that: this silicon window stable performance, fresh-keeping effect is good.
Fruit and vegetable preserving method with air regulating silicon window of the present invention to equilibrium market, is regulated fruit in dull season, vegetables amount, improves the people's livelihood, and develops the economy, and plays ensureing and facilitation.Simultaneously in the dull season, the stored goods price is higher, has remarkable economic efficiency.
In sum, fruit and vegetable preserving method with air regulating silicon window of the present invention, storage procedures is simple, and is with low cost, long fresh-keeping period, good refreshing effect, remarkable in economical benefits.
Below in conjunction with embodiment the present invention is done further explanation.
The present embodiment fruit and vegetable preserving method with air regulating silicon window comprises the steps:
(1) chooses good fruit, vegetables;
(2) go into to store the preceding air regulating silicon window polythene film bag that will have the certain air permeability energy through the osed top of packing into after the pre-heat radiation;
(3) the air regulating silicon window polythene film bag that fruits and vegetables will be housed is positioned over storage under the suitable temperature and humidity environment.
The present embodiment fruit and vegetable preserving method with air regulating silicon window, said silicon window, its silicon film thickness are 0.24mm～0.26mm.This silicon fiml can with the direct heat seal of polyethylene foil, in conjunction with firmly, do not come off.
Present embodiment fruit and vegetable preserving method with air regulating silicon window, said permeability are meant that the oxygen gas permeability amount should be not less than 60 * 10
-9Cm
3/ cm
2S (the every sq cm Air permenbility of per second), the carbon dioxide Air permenbility should be not less than 300 * 10
-9Cm
3/ cm
2S (the every sq cm Air permenbility of per second), the ratio of the Air permenbility of carbon dioxide and oxygen should be not less than 5.Under this condition, permeability is stable, and is ventilative than suitable.
The present embodiment fruit and vegetable preserving method with air regulating silicon window, said external packing is not limited to be inlaid with the polythene film bag of silicon window, also can use other packing boxes, the packing chest that are inlaid with the silicon window.
The present embodiment fruit and vegetable preserving method with air regulating silicon window, employed polythene film bag is inlayed the silicon window, has selected the rational silicon window area of breathing freely, fruits and vegetables have been satisfied in storing breathing, to oxygen and carbon dioxide suction ratio, can be fresh-keeping for a long time, can keep original look, flavor and nutritional labeling.Empirical tests, the refrigeration of the inventive method lower temperature is longer storage period than the following refrigeration of normal temperature.
The present embodiment fruit and vegetable preserving method with air regulating silicon window, storage humidity is generally 80%～95%.Because of fruit, vegetable variety difference, humidity is slightly different.In storage, tighten the air regulating silicon window polythene film bag; In the storage later stage, as occurring the dewfall phenomenon in the bag, can separate mouth opening and ventilate in short-term, in case rot.
The present embodiment fruit and vegetable preserving method with air regulating silicon window, the fruit that is used to store will be won and strict disease and pest fruit, the cull fruit of rejecting in good time.The vegetables that are used to preserve want the selective maturation degree moderate, have no mechanical damage and the vegetables of newly gathering of disease and pest.To in time go into storage after the harvesting.
By actual contrast experiment, the present embodiment fruit and vegetable preserving method with air regulating silicon window is compared with existing common storage method, and storage time obviously improves, and fresh-keeping effect is remarkable, and experimental result sees Table 1.
