Description

Fresh-keeping anticollision packing method during a kind of pear transport
Technical field
The present invention relates to a kind of vegetables and fruits fresh-keeping treating method, and in particular to fresh-keeping anticollision packaging side during a kind of pear transport Method.
Background technology
Pear have the good reputation of " ancestors of all kinds of fruits ".In world's fruit market, apple, pear and orange are referred to as that " three is big Fruit seizes by force ".China is one of area of origin of pear platymiscium, is belonged in the middle of 25 kinds of extended familys in pear, and China just has 14 kinds, Account for more than half, be the most country of pear tree kind in the world.Increase year by year and people with China's pear yield Living standard is greatly improved, and pear into the daily fruit in common people family, there is the work(such as moistening lung, dissolving phlegm, heat-clearing, removing toxic substances Effect.Pears are " ancestors of all kinds of fruits ", because of its fresh and tender succulence, sour and sweet palatability, so have the title of " natural mineral water " again, present pear life Produce, be distributed to large-scale production base development from scattered, eat and process juice processed raw and be combined, expand home sale, developing Overseas market, overcoat foam web is cased again after having preferable development trend, current pear transport to rely primarily on pack, with The phenomenon for causing to damage that collided during pear transport, carrying is prevented, but because foam web is both ends open structure, Er Qiehou Degree is general, and anti-shipping damage effect is general.
The content of the invention
The present invention provides fresh-keeping anticollision packing method during a kind of pear is transported.
The technical solution adopted by the present invention is：Fresh-keeping anticollision packing method during a kind of pear transport, comprises the following steps：
（1）Carragheen and polyacrylamide, maltonic acid sodium, calcium dihydrogen phosphate, sodium acid carbonate are pressed into 100-110:3:5:1:1 Weight than well mixed, by 1:10 volume ratio adds Cortex walnut leaching liquor, 80-85 DEG C is heated to, in 3000-3200r/ Insulated and stirred 23-28 minutes under the stir speed (S.S.) of min, obtain stablizing colloidal solution；
（2）Colloidal solution is passed through in granulation model and is granulated, granulation particle diameter obtains spheric granules in 0.1-0.15cm, will be spherical Particle is dried to water content in 15-18% under 45-48 DEG C of hot blast；
（3）The pear of fresh harvesting is put into packaging bag, and by 100：5 weight ratio adds spheric granules, in packaging bag It is passed through the distilled water of packaging bag volume 1/5-1/4, and to being passed through mixed gas, aeration quantity and packaging bag residual volume in packaging bag Quite, then envelope, the pear after pack is cased storage.
Cortex walnut and water are pressed 1 by the Cortex walnut leaching liquor when making:The volume ratio of 7-8 is mixed and heated to 90-95 DEG C Afterwards, it is evacuated to vacuum and reaches 2-4MPa, vacuum back-flow is extracted 2-3 hours, obtains Cortex walnut leaching liquor；
The mixed gas press 1.5 by oxygen, carbon dioxide, nitrogen:2:1 volume ratio is mixed to get.
After the packaging bag inflation envelope, maximum interspace value >=0.5cm ,≤1cm between packaging bag and pear.
Beneficial effect of the present invention is,
100-110 is pressed by carragheen and polyacrylamide, maltonic acid sodium, calcium dihydrogen phosphate, sodium acid carbonate:3:5:1:1 Weight has fabulous than the glue raw material that is mixed to get through the heating stirring that adds water, the spheric granules colloid for granulating, being dried to obtain Adhesiveness water absorbing properties, make an addition in packaging bag and to distilled water is added in packaging bag, are passed through mixed gas encapsulation, can reply immediately soon Water simultaneously expands, and sticks to pear surface, comfort cushioning can be played under inertial impaction and is acted on and is avoided pear from damaging, and uses When, after the end of tape is sealed, can manually rock a bag endoparticle shape colloid so that graininess colloid uniform adhesion on pear surface, with Play more preferable and comprehensive anticollision buffering effect；
In addition, can be dried again after graininess colloid water swelling, can recycle；
It is solution glue with Cortex walnut leaching liquor, there is Cortex walnut absolute ethyl alcohol leaching liquor preferable bacteriostasis, preservation to act on；
1.5 are pressed by oxygen, carbon dioxide, nitrogen:2:1 volume ratio is mixed to get mixed gas and can postpone pear respiratory climacteric Occur, and have preferable color-protecting function to pear.

Below in conjunction with specific fresh-keeping experiment, the present invention is further described,
The examination of experiment 1 picked up from Bengbu Huaiyuan County in the experiment same day for pear, and 100 pears are selected in selected before experiment, classification altogether Son, is randomly divided into A, B, C, D, E5 group, every group 20；
A groups are stored using the processing method of embodiment 1 to pear；
B groups are not processed；
Cortex walnut leaching liquor is replaced with water by C groups on the basis of embodiment 1；
D groups cancel addition polyacrylamide, maltonic acid sodium, calcium dihydrogen phosphate, sodium acid carbonate on the basis of embodiment 1；
E groups will press 1 on the basis of embodiment 1 by oxygen, carbon dioxide, nitrogen:3:The gaseous mixture that 1 volume ratio is mixed to get Body replaces with air；
Each group treatment is after storage under normal temperature；
Pear is weighed before experiment, sampling in regular 2 weeks is weighed；
And storage period pear is classified, grade scale：
5 grades of before processing fruit standards；
4 grades of slight brown stains of color, color and luster brightness declines；
3 grades of about 1/3 fruit surface brown stains；
2 grades of 1/3-1/2 fruit surface brown stains, pericarp softens；
1 grade is more than 1/2 fruit surface brown stain, and fruit softening dehydration is serious；
0 grade of whole fruit surface brown stain, pericarp softens seriously, and rotting occurs in pericarp；
During experiment, each group pear was weighed in the 2nd, 3,4,5 weeks and is classified respectively and by above-mentioned grade scale, tied Fruit is shown in Table down 1：
Group Average single weight g/ classifications before experiment Average single weight g/ classifications in 2 weeks Average single weight g/ classifications in 3 weeks Average single weight g/ classifications in 4 weeks
A 280/5 280/5 278/4.9 275/4.7
B 285/5 277/4.5 264/2.6 251/1.3
