Several kinds of fruit and vegetable fresh-keeping bag making and using method

Anti-oxidation fresh-keeping bags <br> Made of a 0.08-mm-thick polyethylene plastic film to make a 5075-cm bag, and then put the two bags together (the inner bag is firstly pinned with a number of 10 holes). The toilet paper that is impregnated with 1-2 layers of chemical substance “deoxidizing agent” and air-dried is used to form a deoxygenation-type fresh-keeping bag, which can remove the oxygen that the agricultural product enters during the bagging process, causing fruit and vegetables to rot. Bacteria cannot reproduce due to lack of oxygen, thereby prolonging the shelf life of fruits and vegetables. When used, firstly 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 the fresh-keeping bag and seal it. This method is applicable to the preservation of fresh dates, apples, long bean horns and other products, and can be stored at room temperature for 2 to 5 months and crisp as ever.
In addition to ethylene bags <br> Fruits and vegetables in the storage process will naturally release a natural hormone called ethylene, can cause physiological changes in fruits and vegetables, promote product ripening, aging and even decay. 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-keeping 60-80 days.

Wash the tender corn, tender peanuts, etc. and soak it for 5-8 minutes. Take out cold water and let the temperature drop to room temperature. Take out and air dry. , 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.
