Changes in the Volatile Profile of Wheat Sourdough Produced with the Addition of Cava Lees.

The volatile fraction is of great importance for the organoleptic quality and consumer acceptance of bread. The use of sourdough improves the sensory profile of bread, as well as the addition of new ingredients to the fermentation. Cava lees are a sparkling wine by-product formed of dead microorganisms, tartaric acid, and other inorganic compounds, rich in antioxidant compounds as well as β-glucans and mannoproteins.

Revalorization of Cava Lees to Improve the Safety of Fermented Sausages.

The revalorization of food processing by-products not only reduces the environmental impact of their disposal, but also generates added economic value. Cava lees consist of inactive cells of , and though regarded as a valueless winery by-product, they are rich in fiber and phenolic compounds. In this study, a challenge test was performed to assess the effect of cava lees and a phenolic extract (LPE) derived therefrom on the behaviour of technological microbiota (lactic acid bacteria used as a starter culture) and the foodborne pathogens spp.

Histamine Intolerance: The Current State of the Art.

Histamine intolerance, also referred to as enteral histaminosis or sensitivity to dietary histamine, is a disorder associated with an impaired ability to metabolize ingested histamine that was described at the beginning of the 21st century. Although interest in histamine intolerance has considerably grown in recent years, more scientific evidence is still required to help define, diagnose and clinically manage this condition. This article will provide an updated review on histamine intolerance, mainly focusing on its etiology and the existing diagnostic and treatment strategies.

Safety improvement and preservation of typical sensory qualities of traditional dry fermented sausages using autochthonous starter cultures.

Traditional dry fermented sausages are manufactured without addition of starter cultures in small-scale processing units, their fermentation relying on indigenous microflora. Characterisation and control of these specific bacteria are essential for the sensory quality and the safety of the sausages. The aim of this study was to develop an autochthonous starter culture that improves safety while preserving the typical sensory characteristics of traditional sausages.

Characterization of Staphylococcus xylosus and Staphylococcus carnosus isolated from Slovak meat products.

The aims of this study were to isolate, identify and characterize the population of coagulase-negative staphylococci in different types of Slovak traditional sausages and to determine the metabolic properties of selected Staphylococcus xylosus and S. carnosus strains for the selection of potential starter cultures to use in the processing of sausages. The strains were tested for lactic acid production, survival in the presence of bile and sensitivity to antibiotics.
