Natural food flavours: a healthier alternative for bakery industry-a review.

Abstract

Human beings always remained attracted towards vivid food flavours and aroma. Ever since the food industry came into existence, several brands and industries worldwide have been busy creating storms in the food markets through flavours, aromas, textures and substances to intrigue the consumers' minds. The ingredients that go into the preparation of these food items include a list of various preservatives, taste enhancers, stabilizers, colours and to make it look attractive and delicious but may not be healthy. Most of the flavours that are used by food brands are often chemical based and are synthesized completely in the laboratory. The use of artificial/synthetic flavourings in the form of chemical food additives and taste enhancers lead to long term health issues which include potentialrisks of neurological problems, cytotoxicity, genotoxicity, different types of hypersensitivities and even cancers. Food and Drug Administration (FDA, USA) conduct frequent studies to limit the use of artificial flavouring and additives which are totally chemical based and mimic natural food flavours and extract. Benzaldehyde-an organic chemical closely resembles the flavour of roasted almonds and ethyl vanillin which is 3 times potent thannatural vanilla extract used is various confectionery items. Also several ester derivatives are used for mimicking natural fruit flavours like strawberry, guava and cherry. These chemicals pose a considerable threat to human health, knowingly or unknowingly. Antagonistically, natural food flavours, though not as popular as artificial ones prove to be healthierand carry the same aroma and taste as artificial flavouring agents. This review paper sheds light on the pervasiveness of natural and artificial food flavouring agents in the market, their benefits and drawbacks and how they have been in a constant race for dominating the bakery industry.
