姊妹饭真空包装保质技术试验研究

Experimental Study on Shelf Life of Zimei Food Vacuum Packaging

姊妹饭是黔东南州苗族的地方特产,是用天然植物叶片及花序作染料,并经传统工艺技术对糯米进行染色处理而成的.使用软包装工艺技术延长姊妹饭保质期是食品加工企业目前亟待解决的问题,经过试验表明:采用真空度0.09 MPa抽气压力封袋及在110℃高温高压条件下杀菌20 min能耗最少,最经济划算,保质效果最佳.

Zimei food is a local special product of Miao nationality in Qiandongnan, which using natu- ral plant leaves and inflorescence as a dye and with traditional technology of dyeing processing to gluti-nous rice. Experiments results show the best condition is that the air pressure of sealing bag is 0.09 MPa, the sterilization temperature and time are 110℃ and 20 minutes.
