After dilution, it has a pungent aroma. Easy to be oxidized by air, the product is diluted and stored with propylene glycol, and its fragrance is particularly strong in weakly acidic media. Natural products exist in pineapples, strawberries, grapes, coffee, mangoes, heated beef soups, wine, etc. Trace amounts exist in food, tobacco, and beverages, with a fragrance threshold of 0.04ppb having significant aroma enhancing and modifying effects, making it widely used as an aroma enhancer in food, tobacco, and beverages; Although furanone is widely present in natural products, due to its low content, it cannot meet daily needs. The food industry mostly uses synthetic products.
