Description

A kind of fruit and vegetable preserving method

The present invention relates to be used for the technical field of preserving fruit and vegetable utilizing, is a kind of fruit and vegetable preserving method.

Existing fruit and vegetable preserving method has following several: (1) refrigeration (2) air conditioned storage (3) chemicals, radio sterilization etc.Preceding two kinds of methods reach and restrain respiration and physiological metabolism process by changing the external environmental condition of fruits and vegetables, reduce physical deterioration, and delay aging makes preserving fruit and vegetable utilizing.The back is a kind of to be to kill the pathogeny microorganism, thereby prevents what fruits and vegetables from rotting.As: the storage of fruit and fresh-keeping/vast stretch of wooded country volume-Beijing: Golden Shield publishing house, 1994.7; Fruit and vegetable preservation technique/Xie Yingbian-Jilin: the Yan Bian People's Press, 1999.3; Fruit storing disease control/Fu and beautiful compiling-Beijing: Chinese braille publishing house, 1999.7.But original resistance against diseases before all can not keeping or improve fruits and vegetables and adopting even has reduced fruits and vegetables self resistance against diseases, especially in the storing in the fruits and vegetables body natural wastage of nutriment such as moisture can not replenish supply; Cause body surface " perspiration " ponding in time not eliminate in storing to fruits and vegetables, moist environment has promoted growing of pathogeny microorganism.

The objective of the invention is to overcome above technical deficiency, fruits and vegetables internal milieu in a kind of change storing is provided, keep or improve the method and the regulation and control air humidity degree of fruits and vegetables self resistance against diseases, prevent the preservation method of fruits and vegetables epidermis ponding.

The purpose of wood invention reaches by following measure.

To fill the sack of fresh-keeping nutritious liquid, by securing member it is fixed tightly on the fruits and vegetables branch body and (comprises carpopodium, favour handle, root, stem, branch etc.), fruits and vegetables branch body is inserted in the fresh-keeping nutritious liquid, thereby fresh-keeping nutritious liquid is absorbed by fruits and vegetables through the branch body.Wherein securing member is formed by two, and as shown in the figure: one is single hole rubber stopper (Fig. 1), and another part is circular plastic ring (Fig. 2).Plastic ring (1) is gone up 2～4 sharp tackle shapes of disjunctor projection (2), in order to puncture a body.Plastic ring (1) internal diameter Φ 1 equals or is slightly smaller than single hole rubber stopper (Fig. 1) external diameter Φ 2.Single hole rubber stopper (Fig. 1) aperture Φ 1 has various sizes, and to adapt to a needs of body diameter size, closely zero-clearance of back is gone in the intercalation of assurance branch body.Plastic ring (1) height d is identical or slightly little with single hole rubber stopper (Fig. 1) height d.All there is suitable abducent lug, nib the last bottom of single hole rubber stopper (Fig. 1).The fresh-keeping nutritious liquid sack is plastic products, and outward appearance is like commercially available liquid beverage bag.Plastic ring (Fig. 2) and fresh-keeping nutritious liquid are enclosed in the bag together.The using method of securing member is: after the branch body is inserted single hole rubber stopper (Fig. 1) hole, the plastic ring in the sack of fresh-keeping nutritious liquid (Fig. 2) is enclosed within on the single hole rubber stopper (Fig. 1), the plastic membranous layer of fresh-keeping nutritious liquid sack is fastened to be clamped between above-mentioned two.The branch body punctures rete (or in advance puncture rete with the tax device), and is immersed in the solution, with sharp tackle shape projection (2) on the hand extruding plastic circle (Fig. 2), the branch body is punctured, and is beneficial to the absorption to fresh-keeping nutritious liquid.

Its fresh-keeping nutritious bag is a sealed plastic soft packaging bag, a fresh-keeping nutritious liquid that interior packing quality does not wait and a plastic ring (Fig. 2).In the fresh-keeping nutritious liquid bag, can add an amount of organic high water absorption resin, to adjust its mobile proterties.

, hollow type fruits and vegetables many such as "Hami" melon etc. for the body imperial palace, also available injecting method injects fresh-keeping nutritious liquid in the melon body cavity, and injection port seals with the sterilization adhesive tape.

In the vegetable and fruit packaging container, put into an amount of organic high water absorption resin.In order to regulate and control air humidity in the container, doing the water spray suction before this water-absorbing resin important affair handles, the difference that its water spray water absorption is looked fruit and vegetable varieties, the difference of air humidity and different, its water content is in 0～99% saturation degree scope, wherein in the water that is sucked, can add fresh-keeping medicine and use, also pure water.High hydroscopic resin after suction is handled is packed with gas permeable materials such as nonwoven, puts into the vegetable and fruit packaging container.After also can mixing with the solid, powdery antistaling agent, make composite fresh-keeping paper, promptly the patent No. is: the composite fresh-keeping paper of the described fruits and vegetables of ZL98244581.4.

Principle of the present invention is to adopt securing member that the fresh-keeping nutritious liquid bag is fastened on the fruits and vegetables branch body, required moisture and fresh-keeping nutritious material is provided continuously or injects desired substance for adopting the back fruits and vegetables.Improve the resistance against diseases of fruits and vegetables self inherence, select the organic high water absorption resin of handling through the water spray suction for use, put into the vegetable and fruit packaging container, reach the ponding that absorbs unnecessary aqueous vapor and fruits and vegetables body surface.When air humidity is too low, can discharges aqueous vapor and regulate and control air humidity simultaneously, provide one more to help fresh-keeping environment for fruits and vegetables inside and outside environment, reach fresh-keeping purpose.
