Abstract
The invention discloses a fresh-keeping packaging process of cuiguan pears. The fresh-keeping packaging process of the cuiguan pears comprises the following steps of 1) harvesting and selecting; 2) precooling; 3) dipping with preservative; 4) bagging; 5) inflating fresh-keeping gas; and 6) sealing, performing quality inspection and putting into storage. By the method, the fresh picked cuiguan pears are subjected to precooling treatment, dipped with the preservative, bagged and subjected to gas replacement treatment. According to the packaging process, the fresh-keeping time of the cuiguan pears can be prolonged reliably, and the taste of the cuiguan pears is more excellent than that of the cuiguan pears during harvesting.
Description
Technical field
The present invention relates to Fruits Fresh-keeping Packaging Technology field, more particularly to a kind of freshness retaining packaging technique of Cuiguan pear.
Background technology
Cuiguan pear is domestic sweet Pear varieties ripe earliest, and July early and middle ten dayses are ripe, more early by 2 than the pear and Dangshan pear in the north
Listed to 3 months, 200 grams of single fruit weight, maximum 500 grams, edible fruit rate is up to 96%.Fine and tender taste, soft and succulency, slugging, stone is thin
Born of the same parents are minimum, and taste is dense sweet, soluble solid content 12-14%, rich in multivitamin and change, the trace element such as phosphorus, iron, nutrition
Value is high, deep to be welcome by consumer with higher medical value.
Therefore quickly, cultivated area and yield are all substantially increased, but Cuiguan pear is ripe for Cuiguan pear industry development in recent years
Time relatively concentrates, and fresh keeping time is shorter, causes its selling period excessively to be concentrated, it is difficult to long run supply market, therefore postharvest storage is protected
Fresh work is more and more urgent.
The content of the invention
The invention mainly solves the technical problem of providing a kind of freshness retaining packaging technique of Cuiguan pear, it is possible to resolve existing emerald green hat
The short defect of pears fresh keeping time.
To solve above-mentioned technical problem, one aspect of the present invention is：A kind of fresh-keeping bag of Cuiguan pear is provided
Dress technique, comprises the following steps：
1）Harvest, select：The fresh Cuiguan pear of harvesting, selecting the Cuiguan pear of quality better carries out fresh-keeping packaging；
2）Precooling：By step 1）The Cuiguan pear picked out is put in vacuum pre-cooling equipment carries out precooling, is pre-chilled to less than 15 DEG C, so
Take out afterwards and dry up；
3）Dipping antistaling agent：By step 2）In Cuiguan pear immersion antistaling agent after process, take out after immersion 10-15min and dry up；Its
Described in antistaling agent composition and weight proportion be：Sodium acid carbonate 25-30 parts, sucrose ester 7-12 parts, citric acid 6-10 parts, water
60-70 parts；
4）Bagging：Using transparent polyethylene packaging bag to step 3）Cuiguan pear after process carries out bagging packaging one by one；
5）It is filled with fresh-keeping gas：To step 4）Fresh-keeping gas is filled with packaging bag after handling well；
6）Sealing, quality inspection, warehouse-in：After the completion of inflation, sealed successively, quality restriction, warehouse-in process.
In a preferred embodiment of the present invention, the step 5）In fresh-keeping gas be nitrogen and carbon dioxide mixing
Fresh-keeping gas.
In a preferred embodiment of the present invention, the nitrogen is 4 with the mixing quality ratio of carbon dioxide:1.
The invention has the beneficial effects as follows：The present invention carries out precooling treatment to the Cuiguan pear of fresh harvesting first, then impregnates
Antistaling agent, finally carries out bagging and gas displacement is processed, and the technology of the package can reliably extend the fresh keeping time of Cuiguan pear, and make
Its mouthfeel is better than during harvesting.
