Abstract:[Objectives] Through the use of ZTC-101 clarifying agent for clarifying green tea extract of different stages inindustrialized production of instant tea，we research the ZTC-101 clarifying agent effect of processing green tea extract andoptimum processing condition.[Methods] On the basis of single factor experiment with the material of green tea extract ofdifferent stages，we optimizie the processing condition of ZTC-101 clarifying agent testing green tea extract through theorthogonal test and turbidity and light transmittance of green tea extract are indexes. The paper focuses on discussing theimpact of the adding volume of clarifying agent，concentration of tea extract，pH，testing temperature on the effect ofclarification of green tea extract.[Results]Test shows that the optimum processing conditions for ZTC-101 clarifying greentea extract is 0.6% volume of addition，choosing ceramic membrane retentate，and maintaining at 50℃ and pH 4～6.[Conclusion] ZTC-101 clarifying agent is applicable to industrialized production of instant tea with the evidence showingthat ZTC-101 clarifying agent is suitable for clarifying ceramic membrane retentate，which is economical and practical.
