The objective of this study was to evaluate the flavor profile and acceptability of 7 Cheddar cheeses of varying maturity using descriptive analysis and consumer acceptance tests. Cheddar cheeses (n = 7) ranging in age from 1 to 19 mo were selected based on age, geographic region, and flavor profile. Descriptive sensory profiles of selected cheeses were determined using a trained panel (n = 14) and an established cheese flavor sensory language. Cheeses were evaluated for consumer acceptability in two demographic locations: North Carolina and Oregon. Consumers (n = 100 at each location) assessed the cheeses for overall liking and other consumer attributes. Cheddar cheeses demonstrated distinct differences in descriptive sensory profiles. Average consumer responses between the two locations were not different. Six distinct consumer clusters were identified, and the number of consumers in these clusters differed between the two locations. Consumers differentiated "young" and "aged" cheese flavor, but both young and mature cheeses were perceived by consumers as exhibiting intense Cheddar cheese flavors. Cheddar cheese acceptance varies widely among consumers and is related to consumer preferences for distinct cheese flavor profiles.

Pinot noir character varies significantly with vintage and with maturity within a given vintage. Our objective was to use a gas chromatography-olfactometry technique (Osme) to compare odor profiles of Pinot noir wines from grapes harvested at different maturities, during 1987 and 1988. Odor profiles of Pinot noir wines from those years were very different from each other with only 4 odor-active peaks common to both vintages. Wines made with grapes harvested at the end of the ripening period had more odor-active peaks than wines from earlier harvested fruit. The 1988 wines had more odor-active peaks than the 1987 wines.

AbstractBecause consumers can vary greatly in their value composition, they may seek a range of different benefits from products and brands and hence will react differently to marketing communications emphasizing selected brand benefits. The present study adapts a scale for measuring benefits that drive consumer preferences for craft beer. As part of this process, five dimensions of utility are identified, such as functional, value for money, social, positive and negative emotional benefit. In order to support decisions on market segmentation and brand positioning, those dimensions of benefit are profiled against consumer brand preferences, lifestyle segments, demographic and behavioral variables. Based on the results, guidelines for communication strategies are offered that address the benefits sought by specific segments more holistically.

: Strawberries (Fragaria ananassa) are highly perishable and characterized by a short shelf‐life. Chitosan has been found to be an ideal preservative coating material for fresh berries due to its antifungal and film‐forming properties. However, acid‐dissolved chitosan solutions develop bitterness and astringency tastes, making chitosancoated foods less practical on the real market. Three 1% chitosan‐based solutions were developed for coating strawberries: chitosan in 0.6% acetic acid solution, in 0.6% lactic acid solution, and in 0.6% lactic acid solution plus 0.2% vitamin E. Coated strawberries were packed in clam‐shell boxes and stored at 2°C and approximately 88% to 89% RH for 1 wk, at which time they were evaluated by consumers for “liking” or acceptance attributes and by trained panel for describing the appearance, texture, and flavor of the strawberries. Results from consumer testing at 1 d and 1 wk after coating indicated that chitosan coatings increased the appearance acceptance of the strawberries, but coatings containing vitamin E decreased acceptable appearance of strawberries. Chitosan coatings did not change consumer acceptability of flavor, sweetness, or firmness of the samples. Trained panel results after 1 wk of storage showed that chitosan‐coated strawberries have similar sensory descriptors as those of fresh berries, whereas coatings containing vitamin E developed the waxy‐and‐white surface of the samples. The trained panel did not detect astringency difference among all samples, indicating that 1% chitosan coating did not change astringency of strawberries.

The objective of this study was, through the use of free-choice profiling, to determine flavor characteristics of four acids (citric, malic, lactic, acetic) and two acid blends (lactic/acetic 1:l and 2:l) at three different pH levels (3.5. 4.5. 6.5) and at 0.2% (w/v). Research was conducted to explores flavor differences and similarities among common food acidulants. Generalized Procrustes Analysis was performed on free-choice profiling data, which resulted in three significant principal axes. The first principal axis was characterized by overall intensity and sourness, the second by vinegar and saltiness, and the third by astringency.

Changes in the odor-active volatile compounds produced by `Gala' apples [Malus ×sylvestris (L.) Mill. var. domestica (Borkh.) Mansf. `Gala'] were measured after 4, 10, and 20 weeks storage at 1 °C in regular atmosphere (RA) or controlled atmosphere (CA), and 16 weeks in CA followed by 4 weeks in RA. Aroma was evaluated using the gas chromatography-olfactometry method Osme. Production of volatile esters decreased along with corresponding fruity aromas during CA storage. Hexyl acetate, butyl acetate, and 2-methylbutyl acetate were emitted in the largest amounts and perceived with the strongest intensities from RA-stored fruit. While hexyl acetate and butyl acetate concentrations and aroma intensities decreased during CA storage, 2-methylbutyl acetate remained at the RA concentration until apples had been stored 16 weeks in CA. Perception intensities of methylbutyrate esters with apple or berrylike odors decreased less than straight chain esters in CA-stored fruit. 4-Allylanisole, ß-damascenone, and 1-octen-3-ol, as well as an unknown compound with a watermelon descriptor, were perceived more in RA-stored fruit than in CA-stored apples. Factor analysis indicated the importance of these compounds in `Gala' apples stored 4 weeks in RA. Even though these compounds do not have an apple odor, they contribute to fresh `Gala' aroma.
