Potassium permanganate 5 grams, 5 grams of phosphoric acid, 5 grams of sodium dihydrogen phosphate, 65 grams of zeolite, 20 grams of bentonite, put together to mix (or mix in proportion), add a small amount of water to stir evenly, full infiltration, after drying, pulverize, into particle size of 2-3 mm or 3 mm column. Pack the preservative into a small bag with air permeability, and store it in a container with fruits to be stored.
It is suitable for a variety of fruits, especially for the preservation and storage of melon, grape and peach. 6% - 2%. Potassium permanganate and phosphoric acid, especially phosphoric acid has a strong corrosive, in the preparation and production of this kind of oxidation adsorbent, we should pay attention to personal safety protection. (3) catalyst type. The so-called catalyst ethylene removal, is the use of specific selective metal, metal oxides or inorganic acid catalyzed ethylene oxidation decomposition reaction, suitable for the removal of low concentration of endogenous ethylene.
When making barium hypochlorite 100 grams, chromium trioxide 100 grams, zeolite 200 grams mixed together (also can be mixed in proportion), add a small amount of water to stir evenly, made of particle size 3 mm particles or column, dry or artificial drying, after cooling. The remover can be used for all kinds of fruit, the dosage is 0. 2% - 1. 5%.
