Effect of Saccharomyces cerevisiae cells immobilisation on mead production
Pereira, A. P.; Ferreira, A. Mendes; Oliveira, J. M.; Estevinho, L .M.; Faia, A. MendesMead is a traditional alcoholic beverage obtained by the fermentation of diluted honey performed by yeasts. In this work the potential of application of immobilised yeast cells on single-layer Ca-alginate or double-layer alginateechitosan for mead production was assessed for the first time. The meads produced either with entrapped or free cells were evaluated in terms of quality and aroma profile. The immobilis...
High-cell-density fermentation of Saccharomyces cerevisiae for the optimisation...
Pereira, A. P.; Ferreira, A. Mendes; Oliveira, J. M.; Estevinho, L. M.; Faia, A. MendesMead is a traditional drink that contains 8 % and 18 % (v/v) of ethanol, resulting from the alcoholic fermentation of diluted honey by yeasts. Mead fermentation is a time-consuming process and the quality of the final product is highly variable. Therefore, the present investigation had two main objectives: first, to determine the adequate inoculum size of two commercial wine-making strains of Saccharomyces cere...

Pereira, A. P.; Ferreira, A. Mendes; Oliveira, J. M.; Estevinho, L. M.; Faia, A. MendesMead is a traditional drink, containing 8-18% (v/v) of ethanol, which results from the alcoholic fermentation of diluted honey performed by yeasts. It has been reported that mead fermentation is a time-consuming process, and an important objective of mead makers is to reduce the fermentation time without decreasing the quality of the end product. A significant time can be saved in the fermentation process by in...
Estudo e Diagnóstico de Necessidades de Formação Profissional Florestal na Regi...
Amaral, N.; Bica, A.; Ferreira, A.; Mendes, A.; Viana, H.; Pato, L.; Fachada, M.; Serra, N.Este estudo tem assim por objectivo tornar mais competitivo o sector florestal da RDL, através da melhoria da formação profissional dos seguintes intervenientes nesta área de actividade: produtores florestais, viveiristas, empreiteiros florestais, madeireiros e técnicos florestais. Simultaneamente, este trabalho poderá servir de guião a futuras acções de formação para o sector florestal, originando assim uma ...
