Similar results were observed in Figure 3. For ripened palm, yield of extraction increased as an increase of pH. On the other hand, GA and DE decreased as an increase of pH. Although the alkaline condition gave high yield as in acidic condition, it was reported that alkaline conditions usually caused decomposition of pectin molecules [8]. Consequently, the optimum pH for extraction of ripened palm was 4. In the case of young palm, it was found that low pH condition yield higher extraction yield, GA and DE. This result is supported from another experiment, which is listed in Table 2. Sample Young-pH 2, which was obtained from extraction at pH 2 gave the highest extraction yield at 13.3%. So that pH 2 was used for further extraction of young palm.
