A new generation of fruit and vegetable fresh bags production and use

The anti-oxidation fresh-keeping bag is made of 0.08 mm thick polyethylene plastic film to make a 5,075-cm bag. Then the two bags are put together (the inner bag is firstly stitched with a number of 10 holes), and the middle one is clamped. - 2 layers of toilet paper impregnated with a chemical "deoxidizer" and air-dried, so that a deoxygenation-type fresh-keeping bag is made to remove oxygen that enters the bagging process of agricultural products, so that the bacteria that causes rot of fruits and vegetables are absent. Oxygen can not reproduce, thereby extending the shelf life of fruits and vegetables. When washing, remove the dirt and residual fertilizer and medicine on the skin without breaking the fresh fruit vegetables, then soak it in 0.3-0.5% mannan aqueous solution for 10 minutes, remove it and let it dry naturally, then put it in a fresh-keeping bag and seal it. This method is suitable for the preservation of fresh dates, long bean and other products, can be stored at room temperature for 2-5 months and crisp as ever. In addition to the ethylene preservation bag fruits and vegetables during the storage process, they will naturally release a natural hormone gas called ethylene, which can cause physiological changes in fruits and vegetables, and promote product ripening, aging and even deterioration. At present, the ethylene remover is mainly composed of activated carbon as the representative of the adsorption type and potassium permanganate as the representative of the oxidative decomposition type, although the removal rate of the former is high, but the adsorption fails, the latter has a slow decomposition rate, removal The effect is not obvious and other shortcomings. Polyethylene fruit wax has the characteristics of adsorption, oxidation, and water resistance. It can be made into vinyl bags by coating it in the inner layer of plastic bags. According to the test, fresh peaches and figs that are not treated with any chemical sterilization or preservatives will be sealed in the bag, which will make such products that are currently the most difficult to keep fresh and soft at a normal temperature for half a month and will not rot. Refrigerated, fresh for 60-80 days. Reflective film bag silver plastic film with high reflectivity, high moisture and other characteristics, its heat sealed into a plastic bag for storage of fruits, vegetables and other flavors of agricultural products better. In practice, the 0.5% mannan aqueous solution is heated to 100°C, and the washed tender corn, tender peanuts, etc. are soaked for 5-8 minutes, removed and put in cold water to bring the temperature down to normal temperature, and then taken out and dried naturally. , Hanging a layer of 0.5% pure natural sodium lemon solution, into the storage bag, after sealing can be stored at room temperature for 8 months, its color, flavor as ever.
