Abstract
The utility model discloses a raspberry stores uses soft -packing, supporting role is played in this soft -packing by inside rigid plastic box constitutes with outer freshness protection package two parts that have the effect of gas accent, and the inside of freshness protection package is filled into gaseous, and the main mist that indicates N2, CO2 and O2 seals through the heat -seal mouth. This soft -packing is with the supporting role of small -size rigid plastic box, the gas accent effect of freshness protection package to and fill and mediate the buffering cushioning effect into gaseous gas and combine, can effectively keep the original shape of berry, restrain the fungus growth with the fruit physiological metabolism and reach the purpose that prolongs the freshness date.
Description
Technical field
The utility model belongs to postharvest technology of fruits and vegetables field, particularly a kind of raspberry storage flexible packaging.
Background technology
Raspberry is one of emerging third generation small berries seeds, and be listed in the pioneer tree of development of the West Regions, enjoy " king of world's fruit ", the good reputation of " jinx of cancer ", its special local flavor and high nutritive value make it extremely welcome.Fruit has unique perfume and natural colouring matter, fruit is similar greatly for sugar content and apple, pears, citrus three, amino acid content is higher than apple, grape, be rich in vitamin E and selenium, its anti-ageing material SOD(hepatocuprein) and cancer-resisting substance (tanning acid) content higher than existing any cultivation and wild fruit, its root, stem, leaf also have medicinal efficacy, in food, medicine, cosmetic, health care etc., have extensive use.The fruit sweet and sour palatability of raspberry, has fragrance, nutritious.Raspberry berry quality is tender, and ripening fruits is slightly squeezed and namely breaks juice, nutritious, very easily fungal infection, is difficult to storage and transport, in actual production, common peasant household does not often have fresh-keeping facility and condition, so can adopt some simple and easy to do preservation methods.After mineral water bottle is filled water, put into refrigerator and be frozen into ice and stick together.Fresh fruit is put into bubble chamber with inner wrapping as far as possible, is put into the mineral water bottle that several bottles are frozen into ice in every case angle and case after plucking, so fresh-keeping 2 ~ 3 days of energy.The shelf life of fresh fruit in refrigerator or refrigerator is 3 ~ 5 days.Therefore, the sound development prolonged storage period for raspberry industry seems of crucial importance.
At present, be applied to the main preservation by low temperature of preservation method of fruit of raspberry, controlled atmosphere box, use antisepsis antistaling agent, and freezing Storage.
Preservation by low temperature.To adopt after fresh fruit carries out capsule packaging, put into low-temperature cold store as early as possible fresh-keeping, cold storehouse temperature remains on 0 DEG C ~ 4 DEG C, can extend fresh-keeping 4 ~ 5 days.
Controlled atmosphere.The fresh fruit of maturation is put into plastic bag, 0.5 ~ 1 kilogram every bag, with air distributing device to controlled atmosphere in bag.The oxygen of controlled atmosphere 1% ~ 3% and the carbon dioxide of 10% ~ 15%, under 0 DEG C of condition, freshness-retained 10 days.But this method easily occurs that bottom plastic bag fruit is out of shape because of extruding, the even phenomenon such as juice outflow, thus bring out germ and rot.
Anti-corrosive fresh-keeping.Fruit of raspberry gather after with the halide of 0.5% or the sulfide of 0.5%, adopt stifling anticorrosion, freshness date can be made to extend 10 days.But the food-safety problem caused due to residual quantity limits the application of this method.
Quick-freezing fresh-keeping.This method is adopted during export processing.Fresh fruit will be selected after plucking in time, warehouse-in.The fruit frozen is cased according to required weight.The more low-quality maintenance of general chilling temperature is better.Chilling temperature is at-18 DEG C ~-25 DEG C, and storage time can reach more than 2 years.But the eucaryotic cell structure damage of this method to raspberry is comparatively large, and after thawing, fruit nutrient loss is more, taste bad.
Packaging is one of basic factors of distributing fresh agricultural products; not only there is quantitative and identification function in logistics progress; suitable manner of packing has the function of protection product commodity value especially, and also determine the formation of logistlcs technology system, be the important component part of logistics cost and efficiency simultaneously.How to be studied by performance to fresh agricultural products Cold Chain Circulation process packaging material and uses thereof, the packaging of selection economical and effective, environmental protection, long fresh-keeping period extends the shelf life in the circulation process such as fresh agricultural products is at source processed, logistics, retail, obtains the key that " green market permit " that enter world market is China's distributing fresh agricultural products packaging research.
Summary of the invention
The utility model discloses a kind of flexible packaging for raspberry preservation and freshness, it is characterized in that this flexible packaging has the freshness protection package of controlled atmosphere effect by the passive rigid plastic box in inside, skin, and insufflation gas three part having controlled atmosphere and bumper and absorbing shock function concurrently is formed, the inside insufflation gas of freshness protection package, mainly refers to N
2, CO
2and O
2miscellaneous gas, General N
270-85%, CO
213-25%, O
22-5%, is sealed by heat-sealing.
The controlled atmosphere effect of the supporting role of small rigid plastic casing, freshness protection package and the controlled atmosphere of insufflation gas and shock absorbing effect combine by this flexible packaging, effectively can keep the original shape of berry (fruit percentage of head rice reaches 98%), mould fungus inhibition growth (at 0 DEG C 15 days, mould variability is lower than 2%) and Fruit physiology metabolism and reach the object prolonged storage period.
The utility model mainly completes the investigation of following content:
The utility model compares separately with rigid plastic box, plastic bag, and fresh-keeping fresh fruit when both are combined, and result is as follows:
Table 1 Different Package is on the impact (0 DEG C, 15 days) of fruit of raspberry commodity
Table 2 Different Package is on the impact (0 DEG C, 15 days) of fruit of raspberry outward appearance and nutritional quality
Method of the present utility model takes into full account the feature of fruit of raspberry itself, tender succulence, and the large or foreign object extruding of the amount of avoiding, causes fruit be out of shape, even breakage; In addition, respiration of fruits metabolism is vigorous, adopts high concentration carbon dioxide effectively to suppress respiration and to extend the shelf life.
The utility model combines above two key points, has invented the manner of packing that a kind of applicable raspberry logistics is fresh-keeping, effectively prevent fruit and be out of shape because of extruding, the problems such as even damaged stream juice, meanwhile, the function of bumper and absorbing shock is not only played in outer inflation, also plays the effect suppressing respiration of fruits metabolism.
Accompanying drawing illustrates:
Fig. 1 is that schematic diagram is looked on the fresh-keeping flexible packaging right side of raspberry; Wherein
1: hot-seal; 2: freshness protection package; 3: rigid plastic box; 4: raspberry; 5: the N be filled with
