Our objectives were to determine the acceptability of irradiated fresh ground beef and to determine whether the acceptability was affected by information about benefits or by identifying the samples. The 218 subjects were separated into 4 groups comprising a 2 x 2 design of benefits and information. All subjects tasted 4 patties: 2 irradiated and 2 control. Ratings of overall liking, toughness, and flavor and texture liking were equal for both. Subjects rated the irradiated beef patties juicier than the nonirradiated. Benefit information and sample identification increased the liking ratings of the patties--because the group with no benefit information and no sample identification generally rated all samples lower.

Preference for refined bread is often cited as a reason for the relatively low consumption of whole wheat bread; only a few studies, however, have examined consumer preferences between refined and whole wheat breads, and the results of these studies are inconclusive. Our objective was to determine if refined wheat bread is preferred to whole wheat bread. We hypothesized that people would prefer refined wheat bread. We conducted a taste test with 89 people. They rated their liking of 9 different breads chosen to represent several comparisons between equivalent refined and whole wheat breads. The participants also rated the intensity of 6- n-propylthiouracil (PROP) and completed a questionnaire about their bread preferences and purchasing habits. We classified the participants by their bread preference and their PROP taster status, and then examined the liking patterns of these subgroups. People preferred refined bread to whole wheat bread when both were made using equivalent ingredients and procedures. They liked the commercial samples of refined and whole wheat breads equally well. When people were classified by their bread preference, those who preferred refined bread liked the refined bread better in all comparisons. PROP nontasters liked all refined and whole wheat breads equally. Sensory preferences are a barrier to whole wheat bread consumption, but ingredient or processing modifications can improve liking of whole wheat bread to the level of refined bread.

BSTRACT: To construct a Cheddar taste in media similar to Cheddar cheese, we developed dairy, nondairy, and mozzarella model systems. We trained a descriptive analysis panel to evaluate real and model cheeses for a variety of taste attributes and for Cheddar-like taste. We added sodium chloride, lactic acid, citric acid, and monosodium glutamate to the model systems using mixture designs and used response surface methodology to determine optimum levels of these 3 components. Less sodium chloride and acids were needed to simulate the taste of mild Cheddar compared with aged Cheddar. None of the model cheeses closely mimicked the texture of real Cheddar. We approximated, but did not match, the taste of aged cheddar using our mozzarella base. Panelists generally rated the optimized tastes in the dairy model system as more Cheddar-like than the optimized tastes in the nondairy model. [ABSTRACT FROM AUTHOR] more...
