The peel of dragon fruit is normally disposed by consumer or industrial which can actually<br />

be utilized for beneficial products. Therefore, this the aim of this study is to evaluate the<br />

effect of pectin extracted from dragon fruit (DF) peels for production DF jam. The effect<br />

of different pH (2 and 3) and extraction time (120min and 180min) on the yield of pectin<br />

will be determined. The characteristics of pectin introduced is determined on the degree<br />

of esterification, a methoxyl content and anyhdrouronic acid (AUA) analysis.<br />

Carbohydrate content will be the highest in dragon fruit jam followed by protein, fat and<br />

ash content. It is expected that the properties of pectin produced will influence the final<br />

properties of jam. This study has a potential for food industries to generate incomes and<br />

fully utilize the agro-industrial by product. The production of dragon fruit jam as one of<br />

method to preserve the fruits and to diversify the fruit intake other than consume it fresh<br />

or in juice.<br />
