Applications & Uses
Description
Ethyl propionate is a carboxylic acid ester compound containing ester group functionalities. Due to its distinctive fruity flavour, Ethyl propionate is widely used as a food flavouring and as a fragrance in cosmetics. However, it is flammable and hazardous to humans and may damage the liver and kidneys, and high exposures can cause drowsiness and sleepiness. High exposures may affect the heart and it has been added to the list of special health hazards.
Occurrence
Reported found in several types of wine, in white grape var. Sauvignon, cocoa, apple juice, orange juice, grapefruit juice, guava, melon, peach, pineapple, strawberry, tomato, various cheeses, beer, cognac, rum, whiskey, bourbon, malt whiskey, scotch, cider, brandy, kiwi fruit and mussels.
Uses
Ethyl Propionate is a flavoring agent that is a transparent liquid, colorless, with an odor resembling rum. it is miscible in alcohol and propylene glycol, soluble in fixed oils, mineral oil, and alcohol, and sparingly soluble in water. it is obtained by chemical synthesis.
General Description
Ethyl propionate[105-37-3] appears as a clear colorless liquid with a pineapple-like odor. Flash point 54 °F. Less dense than water and insoluble in water. Vapors are heavier than air.
