Background technique
Fresh-cut fruit and vegetable is also known as lightly processed fruits and vegetables, refers to and fresh fruit is classified, is arranged, is cleaned, cutting, removes the heartFresh, hygienic and nutrition instant food is made after the processing such as (core), finishing, fresh-keeping, packaging.With adding for people's rhythm of lifeFastly, fresh-cut fruit and vegetable is convenient with its, hygienic and nutrition advantage meets the needs of people are food-safe, quick and healthy.In recent yearsCome, the sales volume of fresh-cut fruit and vegetable product increasingly increases, especially in most of developed countries, it has also become the most fast retail food of sales growthOne of product.However, fresh-cut fruit and vegetable is in process, cell tissue structure can be destroyed, and juice outflow, nutriment loss addsFastly, resistance dies down, and shortens shelf vulnerable to microbial infection so as to cause the deterioration of fresh-cut fruit and vegetable color, quality and flavorPhase causes great economic loss.In recent years, fresh-cut fruit and vegetable preservation method is fast-developing, controlled atmosphere, radiation preservation, fresh-keepingAgent is fresh-keeping, natural antiseptic agent is fresh-keeping has been widely studied.Since the food-safe attention of people gradually increases, non-additionPreservation technology is easier by consumers, therefore, a kind of air-conditioning fresh-keeping device that can extend fresh-cut fruit and vegetable shelf life andPreservation method by there is an urgent need in the art to.
Utility model content
To make up the deficiencies in the prior art, different fresh-cut fruit and vegetable respiratory characteristics, design one is utilized in the utility model offerMoney structure is simple, controlled atmospheric packing box easy to use, under the conditions of non-inflatable, has using the stomata and spongy layer that are arranged on boxGaseous environment in effect control box, and by moisture in buffer pocket, extend fresh-cut fruit and vegetable shelf life and keeps its fruit quality.
The utility model adopts the following technical solution: it is a kind of suitable for fresh-cut fruit and vegetable storing sale controlled atmospheric packing box includeOpen topped box body, the draining layer connecting with box body and box cover, the draining layer side wall are equipped with through-hole, are equipped on box cover saturatingStomata and air hole plug, bottom is equipped with spongy layer and protrusion in box body, and the height of draining layer side wall, which is less than, is raised to box bodyThe distance at top.
Preferably, the box body bottom protrusion is circle.
Preferably, groove and groove tegillum are equipped on box cover.
Preferably, the draining layer is transparent paliform containment body, i.e., is provided on draining layer ontology every a distanceOne hole diameter, aperture are the rectangles that length is less than draining layer body height.Partition can be also equipped with inside draining layer, for sameWhen contain the controlled atmospheres of different fruits and vegetables.
Preferably, the packing box material is food-grade polypropylene.
Preferably, the box cover and box body are screw-button.
Preferably, the air hole is the circle of diameter 5mm.
The application method of above-mentioned packing box is: the good fresh-cut fruit and vegetable of working process being put into cold water and is cleaned, then by itIt is put into the draining layer of packing box and removes excessive moisture, draining layer is fitted into packing box box body rapidly, covers box cover, will packGood fresh-cut fruit and vegetable enters cold chain transportation or direct marketing.
The above method further include: load onto fork in the groove on box cover, then cover groove tegillum, stopper ventilative stoppleSon.
When fresh-cut fruit and vegetable be carbon dioxide sensitivity fresh-cut fruit and vegetable, carbon dioxide absorber is put into spongy layer in advance, soSpongy layer is taken out rapidly before the draining layer equipped with removal excessive moisture fruits and vegetables is put into box body afterwards.
The utility model takes full advantage of breathing characteristic design controlled atmospheric packing box and its user after fresh-cut fruit and vegetable processingMethod.This packing box good appearance, structure are simple, material is easy to get safely, easy to carry, be both storing unit and marketing unit,With good practicability；All structures of packing box are made of a transparent material, convenient to observe fresh-cut fruit and vegetable freshness at any time.Packing box is recyclable and repeatedly utilizes；Air hole is set above box cover can be to avoid fresh-cut fruit and vegetable because anaerobic respiration generates strange taste；ThoroughlyStomata plug can control gaseous environment in box at any time；The small fork of edible fresh-cut fruit and vegetable can be placed in groove, groove tegillum canSo that inside grooves article avoids pollution；Draining layer can directly store the fresh-cut fruit and vegetable after cleaning, and the design of fence perithalliumGas in packing box can be made to circulate；Draining layer and cassette bottom portion are equipped with certain distance, can buffered water and carbon dioxide gas to freshCut injury caused by fruits and vegetables；Box body bottom protrusion, the moisture that raised ambient store can be made certain, certain humidity in keeping box, dimensionHold fresh-cut fruit and vegetable freshness；According to fresh-cut fruit and vegetable type selection thickness of spongy layer and whether place, effect is by water in boxDivide and absorb in bottom, spread vapor in packing box uniformly, if holding fruit is carbon dioxide sensitivity fresh-cut fruit and vegetable, can putEntering certain carbon dioxide absorber keeps carbon dioxide content to be in reduced levels.It can maintain in this packing box to fresh-cut fruit and vegetableBeneficial gaseous environment.Before this box, the fresh-cut fruit and vegetable processed is placed in cold water and is cleaned, fruit itself can be reducedRespiratory rate and temperature generate large quantity of moisture and packing box inner wall are caused to haze phenomenon after avoiding fruit from entering cold chain, andThe zymolyte that fruit surface easily reacts with oxygen in air can be washed away to a certain extent, subtract fresh-cut fruit browning speedIt is slow.Fresh-cut fruit and vegetable packing box provided by the utility model and its application method, which have, to extend fresh-cut fruit and vegetable shelf life and keeps its productThe effect of matter has bright prospects.
