Abstract
The invention discloses a modified atmosphere freshness-retaining method for strawberry. Freshly picked strawberry is pre-cooled and put in a packaging container and the mixed gas of oxygen, carbon dioxide and nitrogen is introduced into the packaging container to lead the nitrogen concentration to be 85-95%, the oxygen concentration to be 1-8% and the carbon dioxide concentration to be 1-6%. The packaged strawberry is put in a refrigerator for cold storage at the temperature of 0-2 DEG C. The method leads the strawberry which is liable to oxidation stain to keep fresh and unchanged color and taste within 25 days, thus the product quality is ensured.
Description
Technical field
The invention belongs to the food preservative technology field, relate to the air regulating fresh-keeping method of a kind of strawberry.
Background technology
Strawberry is a berry, and water content is high, breathes vigorously, and moisture loss is fast, and easy bacteria infection.In addition, the strawberry listing phase is comparatively concentrated, the gathering during the peak of open country production, temperature is higher, results, transportation, storage and sell in very easily receive mechanical damage and contaminated by microorganism and cause rotting, become and lose, its freshness date is shorter.Ordinary circumstance, ripe strawberry are placed at normal temperatures and were just begun variable color, spoiled in 1 ~ 2 day, lose commodity value.In the prior art, be mostly refrigeration, can preserve about 7 days drinking under 0 ℃ the low temperature under 90% ~ 95% the relative humidity.Though refrigeration can be postponed the bad variation of fruit, after strawberry was taken out from freezer, it ruined velocity ratio also wanting soon without refrigeration.
Therefore, the research strawberry preservation has important use value.
Summary of the invention
The present invention provides the air regulating fresh-keeping method of a kind of strawberry, and that its purpose is is fresh with interior maintenance at 25 days to the strawberry that is very easy to oxidation stain, color and taste are constant.
For achieving the above object; The technical scheme that the present invention adopts is: the air regulating fresh-keeping method of a kind of strawberry; With the strawberry of fresh harvesting in precooling is placed on packing container; And in said packing container the mist of aerating oxygen, carbon dioxide and three kinds of gases of nitrogen, make that the concentration of packing container nitrogen is that 85-95%, concentration of oxygen are that 1-8%, concentration of carbon dioxide are 1-6%, packaged strawberry is inserted refrigeration in 0 ~ 2 ℃ the freezer.
Related content in the technique scheme is explained as follows:
1, in the such scheme, the strawberry of said fresh harvesting is the strawberry of medium well degree.
2, in the such scheme, during said strawberry precooling, its precooling warehouse temperature is 0 ~ 2 ℃, and the precooling time was more than or equal to 24 hours.
3, in the such scheme, said strawberry is when precooling, and configuration air sterilization system adopts ozone to sterilize in the precooling storehouse.
4, in the such scheme, said packing container is packaging bag.
5, in the such scheme, said packing container is a packing box.
6, in the such scheme, said packing container is the packing box or the packaging bag of low barrier material.
7, in the such scheme, packaged strawberry is stored in 0 ~ 2 ℃ the freezer, the rate of metabolism of little control fresh strawberry can be arranged, reduce its respiratory intensity, suppress the reproduction speed of bacterium.
Because the utilization of present technique scheme, the present invention compared with prior art has advantage:
1, because the present invention adopts compound controlled atmosphere fresh-keeping packing; Composite fresh-keeping gas is replaced the air in the packing box of the strawberry of packing into; Change package gas mixing ratio in the box forms the miniature controlled atmosphere environment in the box---and just form miniature air-conditioned cold store, thereby reached the breathing that slows down fresh strawberry; Suppress metabolism, control bacterial reproduction, thereby make strawberry reach the freshness date (can make controlled atmosphere chain and cold chain reach complete combination) more than 25 days.
2, because packaging material of the present invention adopt low barrier material, has good heat sealability; Has certain gas permeability simultaneously, so that keep the gaseous environment in the packing to keep balance.Such packing can also effectively be protected strawberry to be in a kind of extremely to help fresh-keeping controlled atmosphere environment, have good commodity value simultaneously.
