Payorm wood is typically used as a natural preservative that has an
impact on microorganisms. Increasing environmental temperatures
during harvesting favors the rapid growth of microorganisms
that enhance spoilage. Palm sap of juice had pH of 4.19- 5.23.
Therefore, the cleanliness is very important during harvesting step.
The microorganisms found in palm sugar juice are Saccharomyces
cerevisiae and lactic acid bacteria (Chanthachum and Beuchat, 1997).
The payorm wood can delay spoilage in juice by reducing microbial
populations (Charoenchai et al., 2003). Tannin is the most important
