The term flavor is to define the sensory identification of an edible item. Flavors arise due to biosynthetic function and metabolisms in the organism. Flavor enhancers may be synthetic or natural compounds that are mixed with food to enhance their original flavor. This method of flavor enhancement first originated in Asian dishes where Seaweeds acted as flavor enhancers. Added to the cooked broth to bring out a good flavor.
What is a flavor enhancer?
A flavor enhancer is an organic group of compounds. Classified as natural and synthetic used to add nutritional values and taste to cooked food. Devoid of contaminants, they bring out a better taste of food. Some commonly used flavor enhancers are monosodium glutamate, disodium guanylate, autolyzed yeast extract, and hydrolyzed soy protein.
What are recent insights into flavor additives?
Customer demands are increasing for natural and plant-based food enhancers. Hence many researchers are focused on the selecting and isolation of natural compound which enhances taste and flavor. Plants, fungus, bacteria, and dairy products contain a high composition of natural taste and flavor enhancers. Heat or enzymatic treatment of the raw food increases its flavor properties instantly. Future advancements increase the use of natural food enhancers in food industries and provide customers clean-labeled food.
Natural food enhancer is the compounds that are present within vegetables, yeasts, nuts, fruits, spices, mushrooms, and other raw materials. Few examples are essential oil, turmeric, garlic, ginger, honey, salt, and cloves.
Mechanism of action flavor enhancer
Flavorpotentiators can be understood in 3 basic theories:
(i)Strong (1986): have stated that the flavor potentiators are functioned by increasing the flavor compounds reaching the olfactory cells or by increasing the signals formed by the flavored compounds.
(ii)Schinnelleretral (1972): proposed that 5’- nucleotides unmasked flavor receptor sites, they resulted as unmasked flavor receptor sites so these sites were available for stimulus.
(iii)Saint-Hilarie (1973): concludes that flavor potentiators which formed an interaction with collagen protein at receptor site provided an improved taste stimulation.
Brominated vegetable oil in sodas; How to detect them?
Brominated vegetable oil (BVO) is a plant-derived triglyceride used in sodas to enhance citrus flavor and prevent them from getting separated.
Detection of BVO in soda: BVO can be extracted by using diethyl ether. The ether is mixed with zinc to change it to an inorganic bromide and treated with lead oxide to release bromide. Detected by a fluorescein-treated paper strip that turns pink due to eosin formation. The limit should be 1ppm. Chemical flavor enhancers cause many health issues like nausea, insomnia, fatigue, hydration, and brain fog. So, it is better to use natural enhancers. Moreover, the future trend to use natural ingredients by the food industry will motivate scientists to discover new and clean-label food production resulting in good health.
