Abstract
Candies are fruit products processed by adding sugar in high concentration and often food preservative in order to preserve the fruits. The most commonly used preservative is sodium benzoate. This study aims at investigating the existence of sodium benzoate in Salacca edulis candies and the sodium benzoate levels in Salacca edulis candies using ultraviolet-visible spectrophotometry, and investigating whether the sodium benzoate levels in Salacca edulis candies have met the Indonesia’s National Agency of Drug and Food Control (BPOM) standards No 36 Year 2013 regarding the maximum permissible limit of sodium benzoate as preservative. The samples used were three Salacca edulis candies obtained from different supermarkets/minimarkets. Analysis on sodium benzoate preservative was carried out using two methods, including qualitative analysis on samples with FeCl3 as reactant and quantitative analysis with ultraviolet spectrophotometry. The findings indicate that the three samples of candies are positive with sodium benzoate. The average sodium benzoate levels in samples are 0.36 g/kg (A), 0.38 g/kg (B), and 0.37 g/kg (C). All samples meet the Indonesia’s National Agency of Drug and Food Control (BPOM) standards No 36 Year 2013 regarding the maximum permissible limit of sodium benzoate as preservative, which is 1 g/kg fruit-based material. This level is considered safe for public consumption. Keywords: Salacca edulis candies, sodium benzoate, UV-Vis spectrophotometry.
