Fruit Rot Inhibition of Early Mature Satsuma Mandarin Using Antifungal Patches at Room Temperature

This study was conducted to examine decay incidence of citrus fruit treated with antifungal patches during short-term storage using 10 kg paper boxes at room temperature. It was investigated for 15 days in 'Iwasaki' and for 30 days in 'Miyagawa' treated with 200 mg/kg and 500 mg/kg patches of hexanal, carvacrol, and cinnamaldehyde alone or mixed. When it was treated with 200 mg/kg in 'Iwasaki, The decay rate of fruit was at 1.0% in carvacrol alone. In 'Miyagawa', The decay rate of fruit showed lower at cinnamaldehyde and hexanal+cinnamaldehyde mixture of 500 mg/kg than others. And also hexanal+cinnamaldehyde mixture of 200 mg/kg was twice lower than others. In conclusion, the mixed antifungal patches was more effective in reducing citrus fruit decay in citrus fruits than alone at room temperature.

온주밀감 상온저장 시 항균 패치의 부패과 발생 억제 효과

'암기조생'과 '궁천조생'을 수확 후 단기간 상온저장 시 항균 패치의 부패과 발생 억제효과를 검토하고자 수행하였다. 10kg의 종이상자에 과실을 넣은 후 hexanal, cavarcrol, cinnamaldehyde를 단독 또는 혼합한 200 mg/kg과 500 mg/kg의 항균패치를 부착하여 상온저장하면서 '암기조생'은 15일, '궁천조생'은 30일 동안 부패과 발생을 조사하였다. '암기조생'은 200 mg/kg 처리 시 cavarcrol에서 부패과 발생이 1.0%로 낮았다. '궁천조생'은 500 mg/kg에서 cinnamaldehyde와 hexanal+cinnamaldehyde, 200 mg/kg에서는 hexanal+cinnamaldehyde 혼합이 무처리보다 부패과 발생이 2배 이상 적었다. 항균물질은 단독보다는 혼합 패치가 상온저장 시 감귤 부패과 발생을 줄이는 효과가 높았다.
