Abstract

The consumption of beverages is increasing around the world with the globalization of the food industry. Synthetic additives can cause a potential risk to human health when they are excessively consumed. Thus, it is important that the level of synthetic food additives do not exceed the CODEX standards and similar to authorized levels in United Arab Emirates (UAE) by Emirates Authority for Standards and Metrology (ESMA). The objectives of this thesis were to determine and analyze selected food additives in non-alcoholic beverages and to ensure that the quantified results comply with CODEX standards. The present research aimed at screening the beverages and related fruit-based juices sold in the UAE market for their contents of food additives with focus on synthetic coloring agents, artificial sweeteners and preservatives. Thirty (30) different beverage samples from two batches including fruit juice, nectar, drink, soft drink, energy drink, flavored water, malts beverages and fresh juice have been analyzed for their contents of synthetic color, artificial sweetener and preservatives. Seventeen (17) synthetic food additives including eleven food colorants, two sweeteners and four preservatives were analyzed using ultra high performance liquid chromatography diode array detector (UPLC- DAD). The results indicated that the levels of all additives in the studied samples were within the maximum permitted level (MPL) of the CODEX.
