[ 0.1% ] chitosan 용액에 1시간동안 침지시킨 두부를 에서 저장하면서 두부의 품질 변화를 측정하였다. 의 경우 chitosan 처리구에서 저장 2일째까지 약 1 log cycle정도의 성장이 억제되었으나 3일 이후부터는 대조구와 chitosan 처리구간의 차이는 크지 않았다. 의 경우 chitosan 처리구는 대조구에 비해 저장 전 기간동안 성장이 억제되었으며 10^7\;CFU/mL에 도달하는 시점이 대조구에 비해 chitosan 처리구가
Effect of chitosan on shelf life of soybean tofu was investigated. The quality changes of soybean tofu drained after immersion in chitosan solution for 1 hr were examined during storage at 10, 20 and . The number of viable cell of soybean tofu with treated chitosan was lower about 1 log cycle than that of control after 2 days storage at and , although there was no detectable differences at . pH decrease during storage soybean tofu at was begun after 4 days in soybean tofu with treated chitosan, while 3days in control. Hardness of soybean tofu with treated chitosan was maintained higher than that of control over the storage period at . Shelf life of soybean tofu with treated chitosan was extended about 1 day at compared with control.
