• relative to the initial amount loaded for α-CD, Tetronic 90R4, and pulverized T25a10 tablets were 98.7 ± 6.0, 94.5 ± 6.8 and 97.4 ± 8.8, respectively. Note that even in the case of a mixture of the lactase protein with an amphiphilic block copolymer (such as Tetronic 90R4), the activity is as high as 95

• be responsible for this finding. Moreover, the polymer-bound catalyst can be recycled by extracting the products with diethyl ether and reused with only a minor change in activity. Thus, the TONs obtained were 4300 and 3900 for the first and second run. Conclusion An amphiphilic block copolymer
