Utilization of Endo‐Polygalacturonase fromKluyveromyces fragilisin the Clarification of Apple Juice

摘要

ABSTRACTEndo‐polygalacturonase (endo‐PG) fromKhyveromyces fragilisproduced on whey was used for the clarification of apple juice and its efficacy was compared with that of a commercial pectinase. Endo‐PG was recovered from the fermentation broth with a yield of 60.7 and a purification factor of 3.85. Clarification experiments were conducted at 30°C and 50°C for different times. No significant statistical differences in the final turbidity were observed at the 1 level for samples treated with either enzyme. It was concluded that endo‐PG could be successfully used in the process of clarification of ap
