Abstract

Effect of anoxia treatment on alcohol fermentation in the placenta of oriental melons (Cucumis melo) at different developmental stages was studied. Results showed that fruits at the rapid growth stage (stage III) contained the lowest amount of acetaldehyde and ethanol as compared with fruits at other developmental stages. During anoxia treatment, a steady increase in ethanol content was observed in the placenta of oriental melons, regardless of their developmental stages, while the increment of acetaldehyde content was relatively small. Alcohol dehydrogenase in growing and maturing stage fruits showed increased activity with the maximum value at one day after the onset of anoxia treatment and then decreased gradually. An increase in the activity of pyruvate decarboxylase was also observed during anoxia.

발달단계가 다른 참외 태좌부의 알콜발효에 미치는 무산소처리효과를 검정하였다. 참외의 발달단계별 a-cetaldehyde 및 ethanol 수준을 검정한 결과, 비대 후기 (stage 3)의 과실에서 가장 낮았다. 무산소 처리기간동안 태좌부 중의 ethanol은 꾸준히 증가 하였으며, acetaldehyde 함량의 증가는 상대적으로 미미하였다. 그러나 alcohol dehydrogenase 활성은 무산소 처리 1일 까지 급격히 증가한 다음 서서히 감소하였고, pyruvate decarboxylase 활성은 저온 처리기간 중 증가하였다. 완숙기과실의 경우 두 효소의 활성은 증가하지 않았으나, 발효산물의 축적은 관찰되어, 완숙기 과실의 알콜발효는 효소활성의 증가에 기인하는 것이 아님을 알 수 있었다.
