The utilization of cajuput essential oil as a flavor in candy may produce a physiological active added value. Some compounds of cajuput plant (Melaleuca cajuputi L) have been reported for their anti-microbial activities. Candida albicans is a normal commensal organism in human mouth. However, it may become virulent and responsible for oral diseases known as oral candidiasis. This study aimed to determine the effect of cajuput and peppermint oil in cajuputs candy in inhibiting the C. albicans biofilms formation by using in vitro biofilm assay and viability assay. Furthermore, the influence of concentration of cajuput oil on the anti-microbial activities had been analyzed. All the tested concentration of cajuput oil in cajuputs candy was effective to inhibit the viability of C. albicans. The provision of flavor components of cajuput and peppermint oil could produce synergistic effects compared to a single flavor component. The addition of cajuput oil at 0.6% was able to inhibit the viability of C. albicans. The activities of the cajuput oil showed positive correlation to the concentration. The variable of plus and minus 0.1% addition of the cajuput oil concentration, however, produced no significant difference to inhibit the growth of C. albicans in biofilm. Sensory test, hedonic test, was conducted to evaluate the flavor, aroma, and overall attributes, resulting in no significant difference between 0.6 to 0.8% additions of cajuput oil upon the sensory acceptance.
