摘要
研究表明 ,鲜食玉米鲜穗适宜采收期为授粉后 2 3～ 2 5d。收获后贮存期间鲜玉米含糖量受温度影响极大 ,达极显著相关 (r =0 980 4 ) ,贮存温度低 ,呼吸强度小 ,糖分降解慢 ,保鲜效果好。加工品质和风味由冷热处理的温度和时间决定。热处理时间为 18～ 2 4min ,冷处理温度为 - 45℃～ - 38℃时 。
The techniques of optimum harvesting and fresh keeping of table used maize have been studied since 1994.The results showed that optimum harvesting period of freshear was 23-25 d after pollination.After harvesting there was a significanty negative correlation between sugar content of fresh food maize and its storage temperature(r=0 980 4 ).When the temperature of storage was low its respiratory capacity was small and sugar decomposition was slow,and the result of fresh keeping was good.The processing quality and special flavor were decided by treatment time and temperature of heating and colding.When the time of heat treatment was 18-24 minutes,the temperature of cold treatment was -45 ℃--38 ℃,the result of fresh keeping was the best.
