If oranges can't be eaten in a short time, it's best to keep them fresh in the refrigerator. Because the humidity in the refrigerator is relatively high, in order to prevent oranges from losing too much water, it is necessary to wrap oranges with plastic wrap, which can prevent oranges from losing water. The temperature of the refrigerator is relatively low, which can prevent the fruit from rotting and prolong the storage time of oranges. If the house is kept in the refrigerator, it can be kept for about 1 month, but try not to keep it for that long, because the longer it is kept, the lower the taste will be.
Packaging method of oranges
The storage and fresh-keeping packaging bag used for navel orange packaging classification is a special colorless transparent high-pressure PVC film bag on the market. The selection specifications can be determined according to the fruit size, and there are generally two models: 17× 13 cm (0.6 silk) and19×15cm (0.6 ~10 silk). After the fruit is bagged, the mouth of the bag should be tied tightly, and the intersection should be at the navel or pedicle. If any diseased or damaged fruit is found in the packaging process, it should be removed; If there is water on the surface of the fruit, dry it before wrapping it.
In addition, according to the local purchase and sale situation, it is best to classify the fruit packaging with the help of grading boards, and set a size grading specification for every 5 mm difference in transverse diameter, so that the price can be set according to the size and quality when selling, and the management can be standardized. Navel oranges are packed in thin film bags, which has low fruit loss, good taste retention and low cost, and can avoid mutual infection of rotten fruits.
The temperature of the refrigerator can be set at about 4 degrees. At this temperature, oranges breathe weakly, consume less nutrients and will not be frostbitten. Oranges can't be placed in the frozen layer of the refrigerator, which will lead to bad taste. Freeze the oranges.
