Smoked bacon is a food consumed everywhere and previous work has focused on the sensory properties and acceptability of the product. However, little attention has been given to the non-sensory factors that drive sensory and hedonic perception of this product. In this context, the aim of this work was to study the influence of non-sensory factors on consumer behavior towards smoked bacon, using projective mapping coupled with conjoint analysis. Eight visual stimuli were created using a full factorial design with three factors (convenience, healthiness, and context of consumption), at two levels each. Ninety-five consumers positioned the stimuli in a two-dimensional space considering their similarities and differences, and then, rated their expected liking and purchase intention. According to the projective mapping, consumers based the representation of the stimuli on the three factors und...

This study aimed to evaluate the sensory and hedonic perceptions of chicken burger manufactured with pink pepper residue extract (PPE) added to the meat and to the chitosan film. Five samples were manufactured: CT: control, without antioxidant; DP and FP: addition of PPE to the meat batter and to the film, respectively; C1 and C2: commercial brands of chicken burgers. Consumers characterized the samples using the overall liking test and Check-all-that-apply questions. The samples showed a medium–high level of acceptance and no significant differences were found between them. DP was the farthest sample from the ideal and FP showed positive results, since its characteristics were like the commercial samples. The direct extract application may lead to a reduction in the liking of chicken burgers, demonstrating that the technology of active films is a viable alternative to the use of natur...

Staphylococcus spp. tiene la capacidad de adherirse y desarrollar biopelículas sobre diferentes superficies de contacto. Así el objetivo de la presente investigación fue comparar la producción de biopelículas de Staphylococcus spp. sobre acero inoxidable empleando dos medios de cultivo, leche Ultra High Temperatura (UHT) y Brain Heart Infusion broth (BHI). Se realizaron recuentos microbiológicos de las células adheridas en dos tiempos (12 y 24 h), en los dos medios de cultivo, incubados a 25 °C. Los recuentos de las células adheridas fueron analizados mediante ANOVA y comparación de medias por el test de Duncan (p < 0,05). Las biopelículas de dos cepas (cepa silvestre y cepa de tipo) cultivadas por 12 h en BHI, fueron observadas empleando microscopia electrónica de barrido (MEB). Se obtuvieron recuentos microbiológicos entre 7 y 8 log UFC/cm2. Fue observada diferencia sig...

The objectives of this study were to determine the effect of reducing the content and size of NaCl on the instrumental texture and dynamic sensory profile, and to determine the temporal drivers of liking (TDL). The reduction of the NaCl content decreased the hardness and chewiness parameters, and affected the dynamic sensory profile of the product. The NaCl reduction (<1.0% NaCl) was related to a higher incidence of the attributes off-flavor and dry. In general, the overall liking was driven by the juicy and tasty attributes, the latter being associated with the presence of the sensory attributes salty and seasoned and the texture parameters hardness and chewiness. According to the results, among the treatments with NaCl reduction, the beef burger added with 1.0% micronized salt stood out, since it did not affect considerably the texture parameters, the dynamic sensory profile during che...

Post-weaning diarrhea (PWD) is an often disease affecting piglets. It is caused mainly by enterotoxigenic Escherichia coli (ETEC) colonization in pig gut. Antibiotics has been used to prevent, combat and control PWD and its negative impact on the productivity of pig breeding sector. Nonetheless, antibiotics due to their wide antibacterial spectrum also can reach beneficial gut bacteria, such as Lactobacillus. Lately, essential oils (EOs) have emerged as a potential alternative to using antibiotics in animal breeding because of their effect on bacterial growth. Commonly, citrus EOs are by-products of food industry and the availability of these EOs in the worldwide market is huge. Thus, six commercials citrus EOs were evaluated on ETEC strains, as model of pathogenic bacteria, and on Lactobacillus species, as models of beneficial bacteria. In overall, citrus EOs exhibited a selective antib...
