The alcoholic beverage parakari is a product of cassava (Manihot esculenta Crantz) fermentation by Amerindians of Guyana. While fermented beverage production is nearly universal among indigenous Amazonians, parakari is unique among New World beverages because it involves the use of an amylolytic mold (Rhizopus sp., Mucoraceae, Zygomycota) followed by a solid substratum ethanol fermentation. The...

Spontaneous fermentations are still conducted by several wineries in different regions of Argentina as a common practice. Native Saccharomyces strains associated with winery equipment, grape and spontaneous fermentations of Malbec musts from "Zona Alta del Río Mendoza" region (Argentina) were investigated during 2001 and 2002 in the same cellar. Low occurrence of Saccharomyces on grapes and the...

Makgeolli is a traditional Korean alcoholic beverage. The flavor of makgeolli is primarily determined by metabolic products such as free sugars, amino acids, organic acids, and aromatic compounds, which are produced during the fermentation of raw materials by molds and yeasts present in nuruk, a Korean fermentation starter. In this study, makgeolli was brewed using the wild yeast strain Sacchar...

Yeast immobilization is defined as the physical confinement of intact cells to a region of space with conservation of biological activity. The use of these methodologies for alcoholic fermentation (AF) offers many advantages over the use of the conventional free yeast cell method and different immobilization systems have been proposed so far for different applications, like winemaking. The most...

Free-run juice (“saignée”) from Pinot Noir must was filtered by nanofiltration (NF) and then, with the aim of promoting diffusion anthocyanins, retentate fraction returned to tank immediately permeate at different densities during alcoholic fermentation. This extraction strategy compared thermovinification (TV). The results obtained demonstrate that NF shows promise as an alternative non-therma...

Fermentation characteristics of four strains of brewer's yeast (Saccharomyces cerevisiae strain 70424, S.rouxii strain 2535, S. rouxii strain 2531 and Saccharomyces ludwigii strain 3447) in Yeast Moldbrothcontaining four different fermentable sugars (glucose, fructose, maltose, or sucrose) were studied. Theaim was to consider the suitability of different strain/sugar treatment...
