The Effect of Different Ratios of Maltodextrin and Gum Arabic Towards Physical Characteristics of Encapsulated Black Sapote (Diospyros nigra) Kombucha Powder

---

Black sapote (Diospyros nigra), rich in vitamins and antioxidants, is underutilized but promising for
value-added products like kombucha. Kombucha’s limited shelf life due to fermentation can be
addressed by converting it into powder through spray drying. To achieve acceptable sensorial
properties, this study explores probiotic premixes using encapsulating agents (maltodextrin and gum
arabic) in different ratios (3:1, 1:1, 1:3) at 20% concentration, assessing the physical properties of the
spray-dried kombucha. Physical analyses encompass yield, flowability, solubility, color, water activity,
sedimentation and moisture content. The results indicated significant differences in water activity,
moisture content, flowability, and the a* value, whereas no significant variations were observed in
yield, solubility, sedimentation index, and the L* and b* values. Higher ratios of gum arabic (gum
acacia) were found to lower water activity, reduce flowability, increase moisture content, and
enhance the red color component of the powder. The sample exhibited a moisture content ranging
from 2.9% to 5.18% and water activity below 0.3 in all samples, indicating suitable stability, solubility
remained consistently high above 90%. Despite challenges with flowability and yield, the powder met
acceptable standards for other attributes. However, the quality of the black sapote kombucha powder
requires further detailed investigation. Numerous factors, including particle size and hygroscopicity,
still need to be analyzed. Future research should also prioritize optimizing the spray drying
conditions, as these are critical in determining the final physical characteristics of the powder.
