Effects of Rice Weevil and mold on Quality of Stored Rice

쌀 바구미와 곰팡이가 저장미의 품질에 미치는 영향

Polished rice was stored for 24 weeks at $28^{\c수분함량이 16.0% after infestation with rice weevil (Sitophilus oryzae), inoculation with a storage mold, or both treatment. The moisture contents of stored rice with and without rice weevil were 16.6%-17.3% and 13.70%-14.1% respeotively. Fungal numbers were $4.3{\times}10^{6}$/g to $7.2{\times}10^{6}$/g with insects while no fungal growth occurred without them. There were considerable differences between rice weevil infested- and non-infested rice in rice kernel hardness, 1000 kernel weight, maximum viscosity on amylogram, reducing sugar content, fat acidity, and n-hexanal content in head space gas.

$28^{\circ}{\pm}2^{\circ}C$에서 24주 동안 저장한 쌀은 대조구및 곰팡이를 접종한 경우에는 수분항량이 각각 13.7%$\sim$14.1%로서 곰팡이의 생장은 보이지 않았다. 바구미가 존재할 경우에는 , n-hexanal 함량도 대조구및 곰팡이구에 비하여 현격한 차이를 나타내며 변화하였다.
