Description of drawings
Fig. 1 is the structural representation of food Fruit and vegetable preserving bag of the present utility model.
Among the figure, 1. waterproof ventilated membrane, 2. sustained release agent, 3. plasma carburetion, 4. waterproof ventilated membrane sealing line.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The utility model provides a kind of food Fruit and vegetable preserving bag, as shown in Figure 1, for bag-shaped, is comprised of plasma carburetion 3, sustained release agent 2, waterproof ventilated membrane 1 three parts, is enclosed with sustained release agent 2 and plasma carburetion 3 in the waterproof ventilated membrane 1.Wherein waterproof ventilated membrane 1 is 2 layers, and the edge of 2 layers of waterproof ventilated membrane 1 is affixed by waterproof ventilated membrane sealing line 4, and sustained release agent 2 and plasma carburetion 3 are between 2 layers of waterproof ventilated membrane 1, in the scope of waterproof ventilated membrane sealing line 4.
The technical scheme that the utility model adopts is to be prepared into plasma carburetion 3 by equipment, behind the plasma oil 3 adding sustained release agents 2 that prepare, is filled in the waterproof ventilated membrane 1, then seals with outer packaging bag.Antistaling agent of the present utility model can slowly discharge plasma gas in use procedure in the future, utilize the characteristic of plasma gas, reaches fresh-keeping purpose.
Principle of work of the present utility model is: fruits and vegetables are in storage, and itself can discharge ethene or carbonic acid gas, and these gases are to cause that fruit and vegetable physiological regulation changes, to such an extent as to cause fruits and vegetables premature ripening, the aging basic reason that rots.But plasma gas decomposing ethylene gas and carbonic acid gas reduce ethylene gas and carbonic acid gas concentration, suppress the metabolism of fruit, alleviate the ripening and senescence of fruits and vegetables.In addition, the reason of food apoilage mainly is the effect of bacterium, microbial proliferation and various enzymes.Since plasma gas can instantaneous sterilization sterilization, without the dead angle, can the establishment bacterium and the spreading and alleviate various enzymes to the decomposing and fermenting effect of food nourishment composition of germ, thereby prevent that effectively food decay is rotten, reach fresh-keeping purpose.
