Co-Inoculation with and Reduces Vasoactive Biogenic Amines in Traditional Dry-Cured Sausages.

Dry-cured sausages are traditional in Mediterranean countries, and Paio do Alentejo (PA) is one of the most popular in South Portugal. The aim of the present work was to evaluate the effect of combined starters on the safety and quality of PA preserving its sensory quality. Physicochemical parameters, namely pH and water activity (a), microbiological parameters, biogenic amines, color, texture, and sensory attributes were assessed.

Autochthonous Starter Cultures Are Able to Reduce Biogenic Amines in a Traditional Portuguese Smoked Fermented Sausage.

Traditional smoked fermented sausages are highly appreciated in Portugal and are mostly manufactured according to traditional procedures. The aim of the present work was to evaluate the effect of autochthonous starter cultures on the safety and quality of a smoked fermented sausage, (), preserving its sensory quality. Physicochemical parameters, namely pH and water activity (a), microbiological parameters, biogenic amines, colour, texture profile and sensory attributes were assessed.

Predicting calcium in grape must and base wine by FT-NIR spectroscopy.

Calcium content in sparkling wines may not exceed 80 mg/L due to the risk of aggregation with alginate capsules. The high calcium content usually found in wine and must emphasizes the need to develop alternative and appropriate techniques faster and cleaner than atomic absorption spectrometry (AAS). To obtain a robust model to predict calcium content, FT-NIR spectroscopy was used in 98 base white wine samples and 60 must samples from an Alentejo winery.
