摘 要：
There are many advantages of ultrafiltration applied on the clarification of fruit juice.Three membranes of different materials and cut-off molecular weights were used in the study of the clarification of kiwifruit juice by hollow fiber ultrafiltration.The proper membrane was picked out by the method of fuzzy mathematical comprehensive evaluation.The score was obtained by setting up the model of fuzz two--grade comprehensive evaluation and calculating the experiment data with fuzzy linear transformation .The last results indicated that the membrane,whoSe material was PSFand cut-off molecular weight 40 thousand,was better than the other two membranes used in the clarification of Kiwifruit juice if taking the factors such as the nature of membrane the clarified effect and the uetention of nutrient contents etc Into consider atior.
