安梨银耳复合带肉果汁的生产工艺研究

    Technology of producing Anli compound fleshy juice

    • 摘要: 安梨汁提取时,加入0.2%的果胶酶制剂,可使出汁率提高20%左右。经过添加稳定剂和两次均质可以改善饮料的悬浮稳定性,CMC-Na单独使用时,浓度为0.2%,琼脂与CMC-Na配合使用时,浓度各为0.1%即可。均质条件:第一次均质压力为16.4 MPa,第二次均质压力为11.8 MPa,均质温度为60℃。复合果汁的杀菌处理,采用112℃的温度即可达到要求,这样既达到了杀菌的目的,又较好地保持了带肉果汁的稳定性,极大限度地保存了果汁的维生素C含量。

       

      Abstract: The juice yield can be raised by approximately 20% with 0.2% pectic enzyme preparation added to the extraction of Anli juice. The juice suspension stability can be improved by adding stabilizer to it and homogenizing it twice. The concentration of stabilizer is 0.2% if using CMC-Na only and also if using the compound of agar and CMC-Na. The homogenizing condition is as follows: for the first time, pressure is 16.4 MPa, for the second, presure is 11.8 MPa, and the temperature is 60℃. The ideal temperature is above 112℃ in sterilizing compounded juice, which sterilizes and maintains the stability of the fleshy juice and at the same time, maximizes the retention of ascorbic acid.
