日本农水省食品研究所宣布了利用二氧化碳安全杀虫方法。措施是在高压二氧化碳中放置谷物,然后急剧减压。仅仅几分钟,就能把谷物里的害虫全部消灭。二氧化碳对人体比较安全,不象熏蒸剂和触杀剂那样令人担心残留毒。这种方法虽然成本高,但是能够制造边回收二氧化碳边连续处理的系统。今后将进行处理后的谷物的质量评价,使此方法达到实用。新方法是对装了谷物的耐压容器充填高压二氧化碳,几分钟后急剧减压,恢复常压。在5～30个气压的范围内减压,一切害虫都会死
Japan’s Rural Water Institute of Food announced the use of carbon dioxide insecticide safe method. The measure is to place the cereal in high pressure carbon dioxide and then abruptly depressurize. In just a few minutes, all the pests in the cereal can be eliminated. Carbon dioxide is safer for the human body and does not cause the same concern as residual fumigants and touch detergents. Although this method is costly, it is possible to create a system that can continuously treat carbon dioxide while recovering carbon dioxide. The quality of processed grains will be evaluated in the future to make this method practical. The new method is to fill the pressure vessel filled with cereal with high-pressure carbon dioxide, a sharp decompression after a few minutes, to restore atmospheric pressure. Decompression in the range of 5 to 30 bar, all pests will die
