Research and Development of Coconut Ice Cream
Abstract：In this paper, we studied the influence of the expansion mechanism and process optimization of ice cream by raw materials．Determined the ice cream recipe and process parameters．The results show that the milk, coconut oil, stabilizer and emulsifier affect the physicochemical indexes and flavor of ice cream. The optimal amount of milk for 14%.Coconut milk to instead of water can improve the solids content and aroma flavor of ice cream. Coconut oil instead of butte has greater impact on the ice cream flavor and significantly improved the ice cream aroma. The optimum adding amount was 8%.The compound stabilizer was added 0.2% and the emulsifier was added 0.25% most appropriate, ice cream overrun and melting resistance can achieve the best results. Coconut ice cream making process parameters was determined as follows:1.material mixing temperature:50℃；2.The pasteurization temperature:65,20min；3.Mixing (homogenizing)：10000 rpm，3min；4．Aging time:4h；Freezing time：20min.
