新近,美国佛罗里达州温特赫文农业推广处的女化学家使用油、腊、醋酸纤维素与硝化棉的溶液等材料调制成特别的“油”。用刷子(改为喷雾更好)人工涂抹在水果表面,放在21℃的正常室温下贮藏,既可保鲜,增大香味,延长贮藏时间;而且上述材料来源易得,价格便宜;又无须用冷藏车贮运。该“油”涂后在果皮上产生一层薄膜,可防果内水分向外散失和阴止果内外空气交流,果内不会产生乙烯而变熟。 Recently, female chemists at the Department of Agricultural Extension, Winterberg, Florida, United States, formulated special “oils” using materials such as oils, waxes, solutions of cellulose acetate and nitrocellulose. With a brush (to spray better) Artificial smear on the surface of the fruit, placed at 21 ℃ normal room temperature storage, both fresh, increase flavor, extend storage time; and the above-mentioned materials easily available, cheap; Refrigerated storage and transportation. The “oil” after coating on the skin to produce a thin layer of film, can prevent fruit moisture loss outside and outside the fruit exchange of air inside and outside, the fruit will not produce ethylene and become cooked.
