Evaluation of toxicological metal profiling in different varieties of candies from the local market of Lucknow City, India

Abstract

Virtually almost everyone enjoys chocolates and candies every now and then. Usually, chocolate and candies are the most craved food among children and pregnant women. This craving kicks high during the phase of stress, anxiousness, hormonal changes or mood swings. As children and pregnant women are the most sensitive groups of human population, the presence of any kind of toxicants in their food products can raise serious health concerns. In view of this, an approach has been made to estimate the quantity of nine metals in three different variety of commonly available candies (67 samples) i.e., cocoa-chocolate based, milk based, and fruit flavored candies. Few metals were found at relatively high level in cocoa-chocolate based candies followed by milk based and fruit flavored candies. The findings of this study enlightens the international food safety and public health protection authorities to implement strict permissible limits for the presence of metals in candies. The statistical approach of m­­­ultiple discriminant analysis was also performed in this study to reverse identify the candy groups based on their inter-comparative profiling of multi-elemental contamination among similar type of candy samples which points towards stipulating stringent quality policies and establishing strict standards for manufacturing, processing, storage and transportation of candies and their raw materials.
