SUGAR PALM SEED (ARENGA WESTERHOUTII GRIFF.) IN THAILAND: NUTRITIONAL COMPOSITION AND PRODUCT DEVELOPMENT
Sugar palm seed (Arenga westerhoutii Griff.) is a native wild plant naturally found in the north of Thailand. This study was aimed to determine the nutritional compositions and develop a low sugar sugar palm seed jam to be a healthy product. The previous research showed that the seed collected during April 2009 from six villages in Nan province are a good source of protein and crude fiber (22.91 and 7.63% w/w-dry weight basis) with lower in fat content (0.54% w/w-dry weight basis). This study was carried on dietary fiber in the seeds collected during June 2011. Soluble dietary fiber (SDF) was found in the range of 4.17-11.15 g/100 g and total dietary fiber (TDF) in the range of 5.43-15.20 g/100 g. These results revealed that sugar palm seed shows the potential as health food for human diets. Therefore, a formulation of low sugar sugar palm seed jam was developed. Mulberries was added in the ratio 1:10 for improving color and flavor. Sugar was reduced to 25, 35, 40 and 50% from the original formula and sucralose was used as a sweetener. Quality in terms of spreadability, pH, total soluble solid (TSS), total plate count (TPC), coliform, Escherichia coli (E. coli), yeast and mold and sensory evaluation was determined. The pH of all formula was between 3.12-3.00. TSS decreased regarding to percentage of reduced sugar. 40% of reduced sugar formula had the highest spreadability and overall acceptability score which was significantly different from other formulas (P<0.05). TPC, coliform, E. coli, yeast and mold of all formulas were in accordance with Thai Industrial Standards. Low sugar sugar palm seed jam will be an alternative healthy product for the healthy conscious consumers.
