| Abstract The vinegar is a millenary food, appreciated by consumers worldwide. The rice bran is a rice-processing by-product produced in a large scale, mainly employed in feed. This study describes a method for defatted rice bran (DRB) vinegar production by submerged fermentation, with optimized aeration and stirring conditions, evaluating its physico-chemical properties and acceptance. A 22 Full Factorial Design (FFD) was applied to evaluate the aeration (0.25-1.00 VVM) and stirring (100-500 rpm) effect on the stoichiometric yield (SY), total concentration of ethanol and acetic acid yield (TCY), and acetic acid productivity (AAP). SY ranged from 26.26 to 79.97%, TCY ranged from 78.04 to 100.50%, and AAP varied from 0.056 to 0.473 g L-1 h-1. The stirring... |

| Abstract The aim of this study was to evaluate the influence of chicken nuggets packaging attributes on Brazilian consumer purchase intention. Focus group technique was employed in order to identify the relevant packaging characteristics. Forty consumers were interviewed in six sessions where five different types of chicken nuggets packaging were evaluated. After identifying the most relevant parameters for the study (color, picture, brand, and price), the impact of each characteristic (factor) on the purchase intent was evaluated. The conjoint analysis technique was applied to 100 consumers data. Eight stimuli (labels) were prepared by combining two levels for each factor using a fractional factorial design 24-1. The price significantly influences at the... |
