아황산가스 발생제를 자가 제조하여 포도의 저장 중 병해발생 방지에 이용하는 방법을 확립하기 위하여 sulfite 화합물의 아황산가스 발생 정도와 지속 기간을 측정하고 아황산가스 발생 조절 및 간이 검출 방법을 개발하였다. 포도의 저장 중 잿빛곰팡이병을 일으키는 B. cinerea의 포자 발아와 균사생장은 각각 400 ppm과 3200 ppm의 아황산가스 농도 조건에서 억제되었다. 5종류의 sulfite 및 bisulfite 화합물 중 sodium

In order to establish the method to prepare and use the sulfur dioxide gas generating agent in low temperature storage of grape fruits, the generation capacity from various sulfite compounds was investigated, and the method to regulate gas generation and to detect the gas was developed. The conidial germination and mycelium growth of Botrytis cinerea which causes gray mold disease during grape fruit storage was completely inhibited at the gas concentration of 400 ppm and 3200 ppm, respectively. Sodium hydrosulfite generated the most amount of gas among the investigated 5 different sulfite or bisulfite compounds. By adjusting the number of pinholes on packaging film of the compound or by adding pH adjusting agent, e.g. citric acid or phosphates, it was possible to regulate the amount and duration of gas generation from the compound. Because malachite green was quantitatively discolored by gas, the solution or impregnated paper with the compound could be practically utilized as a indicator detecting gas. Finally, when Muscat Bailey A grape was stored at low temperature with gas generating agent, the disease incidence was reduced after storage.
