Descripción Sensorial Cuantitativa de la Miel de Acacia

En este trabajo se describen las características sensoriales de la miel de acacia. La descripción sensorial cuantitativa fue realizada por un panel, previamente seleccionado y entrenado de acuerdo al procedimiento establecido en IRAM 20005, constituido por cinco hombres y cuatro mujeres de edades comprendidas entre 20 y 30 años, pertenecientes a la comunidad académica de la UTN FRRo. Una vez garantizado el desempeño de los miembros del panel, se realizó el análisis descriptivo de dicha miel, en condiciones controladas de laboratorio. Los atributos analizados fueron intensidad del olor y del color, aroma, fluidez, dulzor, granulosidad, persistencia, cantidad y tamaño de cristales. Las mieles de acacia presentaron dulzor entre moderado e intenso, color ámbar claro sin notas características, olor moderado con notas vegetales, cálidas y florales, mientras que la persistencia resultó entre baja y media. El perfil obtenido contribuye a caracterizar la miel en relación a su origen floral, constituyendo una herramienta de diferenciación, que aumenta su valor agregado a la hora de comercializarl

PROJETO DE EXTENSÃO UNIVERSITÁRIA PARA APOIO E REALIZAÇÃO DA OLIMPÍADA BRASILEIRA DE QUIMICA NAS ESCOLAS DO PARANÁ

Olimpíadas científicas podem representar uma grande oportunidade para alunos se desenvolverem. Este projeto de extensão trata-se de uma proposta de ação para incentivar estudantes de ensino médio das escolas públicas e particulares do Estado do Paraná para uma maior participação na Olimpíada Paranaense de Química (OPRQ). Dentre as atividades realizadas estão ações de divulgação e uma análise comparativa entre as edições anuais desta competição científica, de forma a permitir fazer uma prospecção de novas escolas e alunos participantes. Acredita-se que ao divulgar de forma mais acentuada as olimpíadas no estado do Paraná, poderemos colocar nossos alunos à frente dos melhores do País

Meeting Report: Validation of Toxicogenomics-Based Test Systems: ECVAM–ICCVAM/NICEATM Considerations for Regulatory Use

This is the report of the first workshop “Validation of Toxicogenomics-Based Test Systems” held 11–12 December 2003 in Ispra, Italy. The workshop was hosted by the European Centre for the Validation of Alternative Methods (ECVAM) and organized jointly by ECVAM, the U.S. Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM), and the National Toxicology Program (NTP) Interagency Center for the Evaluation of Alternative Toxicological Methods (NICEATM). The primary aim of the workshop was for participants to discuss and define principles applicable to the validation of toxicogenomics platforms as well as validation of specific toxicologic test methods that incorporate toxicogenomics technologies. The workshop was viewed as an opportunity for initiating a dialogue between technologic experts, regulators, and the principal validation bodies and for identifying those factors to which the validation process would be applicable. It was felt that to do so now, as the technology is evolving and associated challenges are identified, would be a basis for the future validation of the technology when it reaches the appropriate stage. Because of the complexity of the issue, different aspects of the validation of toxicogenomics-based test methods were covered. The three focus areas include a) biologic validation of toxicogenomics-based test methods for regulatory decision making, b) technical and bioinformatics aspects related to validation, and c) validation issues as they relate to regulatory acceptance and use of toxicogenomics-based test methods. In this report we summarize the discussions and describe in detail the recommendations for future direction and priorities

Descripción Sensorial Cuantitativa de la Miel de Acacia

In this research work, are describe sensory features of Acacia honey. Quantitative descriptive analysis was done by a panel previously selected ans trained, according to established in IRAM 20005, constituted by five men and four women, with ages between 20-30 years old, belonging to the University UTN FRRo. After being guaranteed the performance of panel members, was made the descriptive analysis of honey, under controlled laboratory conditions. The features analyzed were intensity of smell and color, fragrance, fluidity, sweetness, granularity, persistence, amount and size of crystals. Acacia honeys had a low-intermediate sweetness, clear amber color without characteristic notes, moderate smell with vegetable, warm and floral notes, while the persistence resulted low-intermediate. The profile obtained allows to characterize the honey with its floral origin, being a differentiation tool, that increases its added value to market it.En este trabajo se describen las características sensoriales de la miel de acacia.
