Conteúdo: | Two components of mandarin peel oil believed to have significant influence on mandarin flavor, thymol and  dimethylanthranilate, were found important to aroma in mandarin peel oil and flavor in mandarin juice. Two monoterpenes, y-terpinene and B-pinene, were also shown to be important to mandarin aroma and flavor. The role of nootkatone in grapefruit aroma and flavor was studied along with its interrelations to other grapefruit flavor components. When nootkatone is above threshold levels, other grapefruit oil constituents apparently have major influence on flavor. Volatile sulfur compounds, hydrogen sulfide, dimethyl sulfide, methanethiol and dimethyl disulfide, were identified in parts-per-million in headspace gases above fresh orange, grapefruit, tangerine, lemon, lime, tangelo and tangor juices. The study included variations in quantity of hydrogen sulfide with time after juice extraction and throughout a season for specific fruit. Quantity of hydrogen sulfide present was decreased more by frost damage to fruit, than by normal maturation during a season. Dimethyl sulfide was detected in canned orange and grapefruit juices and glass-packed orange juice in parts-per-million. This sulfide may be an important contributor to off-flavor in some processed citrus juices.
