Electronic Nose Evaluation of Grape Maturity
… nose to monitor grape maturity by analyzing headspace volatiles. In the first part of the study, system and experimental parameters affecting the electronic nose operation were investigated to optimize detection of wine grape aroma. In the second part, the ability of an electronic nose to …

Frying Stability of Low-Linolenic Acid Soybean Oil and Examination of the P-Anisidine Value Method
… the relationship between p-anisidine value and headspace volatiles, sensory evaluation, and polymers. Partially hydrogenated soybean frying oil was used to fry shoestring potatoes. The oil was evaluated by p-anisidine value, headspace volatile analysis, sensory evaluation, and polymer analysis. …

1-(1H-pyrrol-2-yl)-1,2-propandione is a crucial pheromone component of the rare North American cerambycid beetle Dryobius sexnotatus
… America, the rare Dryobius sexnotatus Linsley. Headspace volatiles from males contained (R)-3-hydroxyhexan-2-one and the pyrrole (ratio 1:0.13), neither of which were detected in samples from females. A field bioassay confirmed that adults of both sexes were attracted only by the binary blend of …

Controlling Light-Induced Flavors in 2% Milk
… oxidation level, riboflavin (Rb) retention, headspace volatiles, and sensory evaluation were analyzed to determine the interaction between light source, packaging material, and storage time. HDPE packaging included translucent package (0% TiO2) serving as control (light-exposed, …

Antioxidant Activity of Ampelopsis Grossedentata Crude Extract and its Major Component Dihydromyricetin
… peroxide value, anisidine value, Totox value, headspace volatiles and headspace oxygen. Antioxidant effectiveness was also evaluated in a cooked beef model system. DHM was more potent than BHA in preventing soybean oil oxidation. The crude extract was not as effective as BHA and DHM, possibly …

Identification of key odorants in fresh-cut watermelon aroma and structure-odor relationships of cis,cis-3,6-nonadienal and ester analogs with cis,cis-3,6-nonadiene, cis-3-nonene and cis-6-nonene backbone structures
… volatile isolation strategy based on static headspace analysis (SHA). In this study, SHA was used to collect the headspace volatiles one minute after initial cutting of the fruit. This enabled a chemical “snap shot” of fresh-cut aroma to be taken. The most potent odorants in the headspace …
