The publication describes the preparation and compilation of Slovenian food composition database. Food composition databases provide comprehensive information on energy values, nutrients content, and other nutritionally important components in food. National food composition databases provide data on domestic foods that are most commonly eaten in the country. Food composition data are essential for research into the relationships between diet and disease, for nutritional labelling, and monitoring of the quality, safety and authenticity of foods on the market, and thus for consumer protection.

This study provides a comprehensive and systematic evaluation of phenolics in strawberry spreads processed according to different industrial procedures and stored under several storage conditions for up to 19 weeks. Total phenolics were determined spectrophotometrically, and individual phenolics were determined by combined liquid chromatography and mass spectrometry: six anthocyanins, four phenolic acids, two flavonols, one flavanol, and one flavone. During storage, the phenolics were modified. The total anthocyanins, vanillic acid, kaempferol, and luteolin decreased, while salicylic and gallic acids increased. Total phenolics, cyanidin 3-(6″-succinyl-glucoside) (here observed for the first time), protocatechuic acid, quercetin, and catechin remained stable. The best phenolic retention was observed in spreads stored at 4 °C. Therefore, the proposed storage process (use of a cold chain) indicates good retention of phenolics in strawberry spreads, which maintain high nutritional and sensorial quality

The effects of a fractionated 70% ethanolic extract of propolis were analyzed at the subproteome level by two-dimensional electrophoresis. Differential detergent fractionation was used to fractionate proteins from the yeast Saccharomyces cerevisiae according to their subcellular localization. Thus, four subcellular proteomes were obtained: cytosolic, membrane/organelle, nuclear, and cytoskeletal. Yeast treatment resulted in changes in the levels of proteins involved in carbohydrate and energy metabolism, antioxidant defense, actin filament dynamics, folding of proteins, and others. On the basis of this information, we can obtain better insights into the processes that are carried out in cells exposed to propolis extract.
