temperature on the activity of dextranases using IC–IPAD were undertaken with relative dextranase activity being measured as the isomaltotriose peak height. The pattern of temperature/dextranase effects was close for pure dextran (Fig. 2a) and dextran formed in juice (Fig. 2b), indicating T2000 was an adequate standard. The ‘‘concentrated’’enzyme was added after a 4.6-dilution to make it economically equivalent to the nearest ‘‘non-concentrated’’ dextranase. However, even at this dilution, the activity was still consistently higher across the temperature range studied than for the ‘‘non-concentrated’’ dextranases (Fig. 2), which highlights the differential between relative economic price and activity. The remarkable similarity of the temperature effects patterns for the ‘‘concentrated’’ and ‘‘non-concentrated’’ dextranases studied (Fig. 2), most likely highlight the same fungal source of the dextranases (Table 1).
