Three domestic and 12 imported commercial Jasmine rice varieties were evaluated by a trained sensory panel and by 105 Asian families who live in the State of Arkansas. Results showed that consumers preferred imported over domestic products. According to consumers, the sensory characteristics most important to the acceptance of cooked Jasmine rice were, in order of decreasing importance, color, favor, aroma, stickiness, and hardness. Using descriptive data, we evaluated predictive models of Jasmine rice's overall acceptance. These models allowed us to identify important sensory characteristics that encouraged Asian consumers to accept Jasmine rice. Such characteristics included flavor (that is, aroma, aromatics, feeling factors, and aftertaste), texture, and visual attributes. Data collected here could be useful to the U.S. rice industry in developing an understanding of the drivers of Jasmine rice acceptance.

Cereal Chem. 77(2):259-263The effects of postharvest conditions (i.e., rough rice moisture content, storage temperature, and storage duration) on sensory quality of one longgrain rice cultivar grown in Arkansas (Cypress) were evaluated using a professional descriptive sensory panel. Eight textural (adhesion to lips, hardness, cohesiveness of mass, roughness of mass, toothpull, particle size, toothpack, and loose particles) and six flavor attributes (overall rice impression, sulfur, starch, grainy, metallic, and cardboard) were identified as most important in describing the sensory characteristics of cooked Cyress rice. Postharvest conditions had significant effects on rice sensory quality, and regression models illustrated the effects of each postharvest variable and their interactions. 2 Corresponding

The effect of deformation (10% to 90%) and deformation rate (0.2 to 10 mm/s) on both maximum compression force and correlation between sensory and instrumental measurements of hardness were investigated for 26 commercial cheeses. Log-linear regression models were used to model the relationship between deformation rate and maximum compression force and fitted well to the relationship, indicating that maximum compression force is a log linear function of deformation rate. Deformation had a large effect on the correlation between sensory and instrumental hardness, while deformation rate had a small effect. The optimal deformation and deformation rate for the maximum correlation were 70% to 90% and 1.0 mm/s, respectively. This implies that an optimal combination of deformation and deformation rate can be used for maximizing the correlation between sensory and instrumental hardness for cheese products.

Twenty‐one rice samples covering examples of aromatic, long and medium grain, instant, and parboiled products were evaluated by a group of 120 Asian consumers, currently living in the United States and by a professionally trained sensory panel. Results showed that imported Thai Jasmine rice was preferred by this group of Asian consumers over every other rice tested including domestically grown Jasmine rice. The most important acceptance factors for Asian consumers were cooked rice appearance and aroma. Predictive models of rice overall acceptance were evaluated using descriptive sensory evaluation data (i.e. including appearance, flavor and texture attributes). These models allowed the identification of sensory characteristics most important to rice acceptance by this consumer group. This information could be useful to rice breeders to select for specific sensory characteristics expected by Asian consumers.
