BACKGROUND A demand on raw fermented meat products depends on their availability, price and the culture. In Poland, raw meat products have a several hundred years, although limited to the Podlasie region, tradition of manufacturing. Therefore, in spite of widening of Italian, Spanish, Portuguese, German and recently even the Czech Republic products assortment on the Polish market, the consumpti...

High throughput sequencing could become a powerful tool in food safety. This study was the first to investigate artisanal cheeses from Belgium (31 batches) using metagenetics, relation Listeria monocytogenes growth data acquired during previous project. Five cheese types were considered, namely unripened acid-curd cheeses, smear- and mold-ripened soft Gouda-type Saint-Paulin-type cheeses. Each ...

A dry fermented sausage (chorizo de Pamplona) was elaborated with the simultaneous addition of a lipase (Novozym 677BG) and a protease (Flavourzyme) and ripened during 21 days, in contrast to the control without enzymes and ripened during 35 days. Faster and more intense lipolytic and proteolytic activities were observed in the modified sausage, despite its shorter maturation time. At the end o...

Pigments are important contributors to the appearance and healthful properties of both avocado fruits and the oils extracted from these fruits. This study determined carotenoid and chlorophyll pigment concentrations in the skin and three sections of the flesh (outer dark green, middle pale green, and inner yellow flesh-nearest the seed) and anthocyanin concentrations in the skin of Hass avocado...

A study of the after-ripening of ‘egusi’ melon [Citrullus lanatus (Thunb.) Matsun and Nakai] fruits was undertaken at the Teaching and Research farm of the University of Agriculture Makurdi in the wet and dry season productions of 2005 and 2007. The aim was to monitor its effects on seed quality. Fruits were harvested at two leaf colour stages [i.e. when leaves started turning yellow (LTY), and...

We explore the roles of gibberellin (GA) signaling genes SLEEPY1 (SLY1) and RGA-LIKE2 (RGL2) in regulation of seed germination in Arabidopsis thaliana, a plant in which the hormone GA is required for seed germination. Seed germination failure in the GA biosynthesis mutant ga1-3 is rescued by GA and by mutations in the DELLA gene RGL2, suggesting that RGL2 represses seed germination. RGL2 protei...

BACKGROUND/OBJECTIVES Kimchi is a traditional Korean fermented vegetable containing several ingredients. We investigated the protective activity of methanol extract of kimchi under different fermentation stages against oxidative damage. MATERIALS/METHODS Fresh kimchi (Fresh), optimally ripened kimchi (OptR), and over ripened kimchi (OvR) were fermented until the pH reached pH 5.6, pH 4.3, and...

Freshly-harvested seeds of Avena sativa L. do not germinate when imbibed at temperatures higher than 25 degrees C. This high temperature dormancy is due to the seed coats, and to the low activities of glycolysis and the oxidative pentose phosphate pathway (OPP) in the embryo. The analysis by exclusion chromatography of soluble NADP(+) phosphatase activities of embryos revealed two isoforms: a 3...
