Volatile compounds are responsible for the wine "bouquet", which is perceived by sniffing the headspace of a glass, and of the aroma component (palate-aroma) of the overall flavor, which is perceived on drinking. Grape aroma compounds are transferred to the wine and undergo minimal alteration during fermentation (e.g., monoterpenes and methoxypyrazines); others are precursors of aroma compounds...
Pandanus amaryllifolius leaves are used in food preparation in Asian countries as flavoring agent. It was primarily used for giving a particular fragrance to rice preparation. Later on it was used in bread preparation to give a typical nutty flavor. The aroma compound is 2-acetyl1-pyrroline derived from amino acid phenylalanine. In this investigation an attempt has been made to find out effect ...
Volatile compounds are responsible for the aroma and contribute to the flavor of fresh strawberries (Fragaria ×anannassa), red raspberries (Rubus idaeus), and blueberries (Vaccinium sp.). Strawberry aroma is composed predominately of esters, although alcohols, ketones, and aldehydes are also present in smaller quantities. The aroma of raspberries is composed of a mixture of ketones and terpenes...
Electronic noses have the benefit of obtaining smell information in a simple and objective manner, therefore, many applications have been developed for broad analysis areas such as food, drinks, cosmetics, medicine, and agriculture. However, measurement values from electronic noses have a tendency to vary under humidity or alcohol exposure conditions, since several types of sensors in the devic...
Sweet cream liquid buttermilk and skimmed milk ingredients were heat processed and/or exposed to fluorescent light to determine changes in potential flavor compounds. Solid phase microextraction-gas chromatography/flame ionization detection was used to analyze the concentrations of the volatile compounds (2-butanone, 2-pentanone, acetaldehyde, diacetyl, hexanal, methyl sulfide) found in the two...
KEYWORDS Flowers, berries, leaves, barks and roots of different plants have been used through the ages as a source of flavor in food and perfume preparations. The volatiles responsible for the flavor of botanicals can be extracted from the plant material as "essential oils" (EOs), called also volatile oils or ethereal oils. The term essential is intended to indicate that the oil is the fragrant...
Fruit flavor is a result of a complex mixture of numerous compounds. The formation of these compounds is closely correlated with the metabolic changes occurring during fruit maturation. Here, we describe the use of DNA microarrays and appropriate statistical analyses to dissect a complex developmental process. In doing so, we have identified a novel strawberry alcohol acyltransferase (SAAT) gen...
Rice (Oryza sativa L.,) plants release a complex profile of volatile organic compounds. Present study investigates the differences in compounds from four rice landraces viz., Karuthakar, Norungan, Thavala Kanan and Varappu Kudaichan each under conditions like healthy, mechanically damaged, ones infested by brown plant hopper Nilaparvata lugens Stal yellow stem borer Scirpophaga incertulas (Wlk....
