Refined Hemisphaericin Stabilization by Microencapsulation with Arabic Gum and Spray Drying

摘要

Better stability at the assayed time of storage was found for proteolytic preparations obtained with 7.9 % AG at 120 °C (experimental run 13), which improved the initial activity by 14.8 %; similarly, capsules prepared with 10 % AG at 130 °C (run 7) showed a 14.2 % greater activity than the initial sample (zero time). The sample with the most stability was that obtained at the central point, with 15 % AG and 120 °C; nevertheless, this sample presented lower activity (711 TU) than those obtained under the assayed conditions in runs 7 and 13 (932 and 890 TU).
