Conteúdo: |
Objetivou-se neste trabalho determinar os teores de metais pesados em amostras de solos de um topolitosequencia coletada no Triangulo Mineiro, Estado de Minas Gerais, para testar a hipotese de que tais elementos podem ser utilizados na identificacao e separacao da influencia do material de origem. Os teores de Cd, Cr, Cu, Fe, Mn, Ni, Pb, e Zn foramm determinados por dois procedimentos de ataque acido: HNO3/HCIO4 (4:1) e HF/HNO3/HCIO4 (20:6:3), e dosados por espectrofotometria de absorcao atomica. Tecnicas de analise multivariada foram utilizadas. Os resultados permitem estabelecer que os metais pesados sao indicativos do material de origem, podendos ser usados na separacao e delimitacao de sua area de influencia. As tecnicas multivariadas adotadas mostraram-se viaveis nesse modelo de estudo quando analisados conjuntamente. |

Agricultural studies focusing on the development and/or improvement of new varieties of fruits and vegetables usually prioritize the productivity, disease resistance, response to fertilization, and higher nutrient content. However, new product development needs to take into account not only flavour preference, but also consumer preference for appearance since without tasting products, consumers have to make decisions based on the way a product looks. The present study evaluated the sensory characteristics and consumer preference of ten promising accessions of organic cherry tomato for fresh consumption aiming at identifying the sensory attributes related to appearance that contributed to consumer liking/disliking the fruit. More specifically, the objective of the study was to guide producers regarding the target appearance attributes that play a role on consumer acceptance of cherry tomatoes. Ten accessions of organic cherry tomatoes were evaluated by a trained panel using the QDA methodology, and also by 80 tomato consumers for the acceptance of appearance and intention to purchase. The results achieved after integrating these two data sets (from the trained panel and consumers) in a multidimensional map allowed the elucidation of consumer liking of tomatoes in relation to the appearance, i.e. drivers of liking/disliking were identified. Results revealed that tomatoes with round shape and red colour (reddish) (cultivar ENAS 1031, ENAS 1010, ?Perinha Agua Branca?, Super Sweet, and ?Joana?) were the most liked cherry tomatoes. Those genotypes were also liked by the smallest segment (17.5% of participants) but for them unusual shapes (oblong and pear), orange-yellow colour, and bigger size were also liked. Despite the small number of participants in this study (80 consumers), new shapes and colours for the organic cherry tomatoes could be considered promising alternatives in the Brazilian market, and can be an opportunity for the producers of the state of Rio de Janeiro.
