Monofloral honeys produced by stingless bees M. subnitida Ducke and M. scutellaris Latrelle in typical flowering of the Brazilian semi-arid Ziziphus juazeiro Mart (juazeiro), Croton heliotropiifolius Kunth (velame branco) and Mimosa arenosa willd Poir (jurema branca) were characterized in relation to volatile and sensorial profile. It identified 11 sensory descriptors and 96 volatile compounds. It was noticed a strong effect of flowering in sensorial profile and volatile of honeys. Juazeiro honey stood out with a higher characteristic aroma, taste sweet, caramel flavor and levels of aromatic aldehydes; jurema honey has been described with herb and beeswax aroma and the presence of sulfur compounds and ketones; volatile acids associated with acid taste, medicinal taste and clove aroma characterized the velame branco honey. These results demonstrate that the knowledge of the sensory and aroma profile of these honeys can contribute to characterization of its floral and geographical identity.
-The objective of this work was to evaluate the growth and the production of banana plants with resistance to black leaf streak disease (BLSD), in comparison with the performance of traditional cultivars susceptible to the disease. Twenty cultivars were planted at the Jaguaribe-Apodi plateau, in Northeastern Brazil: 15 with resistance to BLSD,
RESUMOO perfil sensorial de requeijão cremoso foi desenvolvido por meio da Análise Descritiva Quantitativa (ADQ) utilizando-se quatro marcas comerciais do produto. Onze termos descritivos foram desenvolvidos por uma equipe de provadores selecionados, que geraram também a definição de cada termo e as amostras-referência. Os dados obtidos foram submetidos a ANOVA, teste de Tukey e Análise de Componentes Principais. O requeijão da marca A caracterizou-se por apresentar baixa consistência e aparência lisa, enquanto a característica predominante na marca B foi o sabor salgado muito intenso. Os produtos das marcas C e D apresentaram perfis sensoriais semelhantes entre si e distintos da marca A, por serem mais consistentes. Foi também realizado um teste de aceitação utilizando escala hedônica de nove pontos. Todas as marcas apresentaram alta aceitabilidade global, não apresentando diferença significativa entre si. A aceitação dos consumidores foi baseada no manuseio do produto, os quais gostaram mais das amostras mais consistentes e com menor formação de fio. Palavras-chave: requeijão cremoso; controle de qualidade; análise sensorial; análise descritiva quantitativa; aceitação.
SUMMARYSENSORY PROFILE AND ACCEPTANCE OF REQUEIJÃO CREMOSO CHEESE. Requeijão cremoso is a type of smooth and spreadable cheese, manufactured with milk coagulated by natural acidification and addition of milk cream or butter oil. The sensory profile of four commercial brands of requeijão cremoso was developed through Quantitative Descriptive Analysis (QDA). Eleven descriptive terms, their definitions and reference samples were generated by a selected and trainned panel. The statistical analysis included Analysis of Variance (ANOVA), Tukey s Test for means, and Principal Component Analysis (PCA). Brand A showed low consistency and a smooth appearance. The main attribute of brand B was a strong salty taste. Both products C and D showed very similar sensory profiles, presenting higher consistency than brand A. Laboratory consumer tests were also carried out, using a nine point hedonic scale. All products showed good acceptance, but subjects preferred the samples with higher consistency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
