12 Higher alcohols and acetate esters are important flavour and aroma components in the food 13 industry. In alcoholic beverages these compounds are produced by yeast during fermentation. 14 Although S. cerevisiae is one of the most extensively used species, other species of the 15 Saccharomyces genus have become common in fermentation processes. This study analyses 16 and compares the producti...

When lepton flavour effects in thermal leptogenesis are active, they introduce important differences with respect to the case in which they are neglected, the so-called one-flavour approximation. We investigate analytically and numerically the transition from the one-flavour to the two-flavour case when the τ -lepton flavour becomes distinguishable from the other two flavours. We study the impa...

Meat and meat products, which form a major part of our diet, are very susceptible to quality changes resulting from oxidative processes. Quality of fermented food products depends on the course of various physicochemical and biochemical processes. Oxidation of meat components in raw ripening products may be the result of enzymatic changes occurring as a result of activity of enzymes originating...

Mead is a traditional drink that contains 8%-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 Sacchar...

Rocket salad (Diplotaxis tenuifolia; wild rocket) is an important component of ready to eat salads providing a distinct peppery flavour and containing nutritionally relevant compounds. Quality deteriorates during post-harvest, in relation to time and storage temperature amongst other factors. Volatile organic compounds (VOCs) are easily measurable from rocket leaves and may provide useful quali...

Wine yeasts produce ethanol and a myriad of other metabolites during fermentation that give the final wine its unique organoleptic fingerprint. The complex network metabolic pathways leading to production these flavour compounds is largely dependent on redox enzymatic reactions make use NAD(H) NADP(H) cofactors. In this work, we investigated cofactor balance management two genetically related y...
