What is the shelf life of fruit after vacuum packaging

by admin

the shelf life of fruits after vacuum packaging should be determined according to different fruits. Vacuum packaging bags can isolate fruits from the air and, of course, prevent most bacteria from reproducing, but generally fruits cannot be stored in a vacuum environment

fruits are usually preserved by controlled atmosphere. In other words, oxygen is replaced with inert gas such as nitrogen. Under vacuum environment, a certain proportion of inert gas is filled, which can be stored for about 3-7 days. Usually hard fruits are more suitable for vacuum packaging, while soft fruits are not suitable

extended data:

the main function of inflatable packaging is not only the deoxidation and quality assurance function of vacuum packaging, but also the functions of compression, gas resistance and preservation, which can more effectively maintain the original color, aroma, taste, shape and nutritional value of food for a long time

in addition, vacuum packaging is not suitable for many foods, but inflatable packaging must be used. After the food is pumped and packaged by the food vacuum packaging machine, some gas is filled to make the filling pressure in the packaging bag greater than the atmospheric pressure outside the packaging bag, which can effectively prevent the food from being crushed and deformed under pressure, and does not affect the appearance, printing and decoration of the packaging bag

after vacuum, the inflatable packaging is filled with a single gas such as nitrogen, carbon dioxide and rare gas or a mixture of 2-3 gases. Among them, nitrogen is a gas with relatively stable chemical properties, which can protect articles from external interference such as oxidation, and keep positive pressure in the bag to prevent the package from being flattened and damaged

vacuum nitrogen filling packaging can be used for tea, nuts, melon seeds, meat floss, puffed food, fruit and vegetable chips, milk powder, dehydrated vegetables, etc; Some baked foods, such as moon cakes and cakes, have medium water content and high oil content. The shelf life of ordinary packaging is very short. After vacuum nitrogen filling and carbon dioxide packaging, the shelf life can be 2 ~ 5 times longer than that of ordinary packaging.

it depends on what kind of fruit, such as apples and pears, can last for one or two months, but it consumes internal energy, so it’s not delicious when it’s long Oranges are much shorter It mainly depends on the ambient temperature and ventilation
