ABSTRACT
A lemon-flavored drink would hardly taste like lemon if it did not have the sourness associated with the fruit that is contributed by its high citric acid ingredient content. Moreover, this same beverage would not be palatable if it did not contain enough sugar to render it sweet enough to drink. Indian tonic water beverages are usually nothing more than lemonades with a small amount of the added bitter-tasting ingredient quinine. In food technology terms, these ingredients, like the acids, sweeteners, and quinine, are considered substances that contribute to the sensory profile of a beverage and round off the distinctive flavor of the product to make it palatably acceptable and pleasant to the consumer.
