Análise descritiva quantitativa do palmito de pupunheira Quantitative descriptive analysis of pejibaye palm heart

Este estudo foi conduzido para descrever o perfil sensorial do palmito de pupunha. A análise descritiva quantitativa (ADQ) foi utilizada para descrever os atributos sensoriais relacionados à aparência, aroma, e textura de três marcas comerciais de palmito de pupunha. As amostras foram avaliadas por uma equipe selecionada com onze provadores e foram definidos nove atributos sensoriais: cor amarela, aparência uniforme e úmida, aroma e sabor não característicos, sabor acido, residual acido e textura macia. Houve diferenças significativas em seis atributos entre as três marcas testadas. Os provadores descreveram os palmitos de pupunha como: cor amarela clara, aparência uniforme e úmida, aroma e sabor não característicos e sabor ácido com valores intermediários, residual acido e amargor final com valores de pouco e textura muito macia a uma textura intermediária.<br>This research was carried out to establish the sensory profile of pejibaye palm heart. The quantitative descriptive analysis was used to establish the sensory attributes related to appearance, flavor, taste and texture of tree commercial marks of pejibaye palm heart. These samples were evaluated by eleven trained panelists who described nine sensory attributes: yellow color, uniform and humid appearance, non-characteristic aroma and flavor, acid flavor, residual acid taste, and soft texture. There were significant differences in six attributes among the three tested marks. Panelists described the pejibaye palm heart as: light yellow color, uniform and humid appearance, non-characteristic aroma and flavor, acid flavor with medium values, acid residual taste and bitterness final taste from little values and high soft texture to an medium value texture

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
