The by-product of curd, usually is discarded, can be fermented using either Neurospora (Neurospora sitophila) or Rhizopus (Rhizopus oligosporus) yeast to make oncom Genistein is a phytoestrogen, an estrogen-like chemical compound present in plants, that has anti-inflammatory property. Genistein can be determined by UV spectrophotometric method based on the UV absorbance of its complex with aluminum chloride. Addition of acid is a critical point in the procedure. The aim of this research was to know whether genistein is still contained in oncom This research also studied about oncom's activity on carrageenan-induced mice. Acetosal was used as drug control. Result showed that genistein was detected contained in oncom extract. The in vivo assay indicated that oncom extract (dose 1,000 mg/kg of body weight) reduced oedema in carragenan-induced paw of mice, which potencies were 066 times lower than that of acetosal's. Oncom might be useful as food and as a weak inflammation reducer as well.展开更多

Quality of the measurement for appropriate parameter in wine sample is given by uncertainty. Therefore, protocol of analysis has to have an uncertainty of measurement and should be made in accredited laboratory. In Slovakia, there are six wine growing regions (Tokaj, east Slovakia region, south Slovakia region, middle Slovakia region, Nitriansky region and Little-Carpathian region) where the quality wines with protected designation of origin are produced. Central Controlling and Testing Institute in Agriculture in Bratislava is a state organization, which has an accredited laboratory for testing wine products before introduction into the market. This article presents the results of the authors' measurements in proficiency testing FAPAS (food analysis performance assessment scheme) which were organized by Central Science Laboratory in York (England) in 2011. The authors add also interlaboratory comparison in 2012 between Slovak accredited laboratories. The results show very good agreement. Quality control in the wine sector presents very important feature in the market, therefore, using certified reference materials and checking the accredited laboratories with interlaboratory comparisons is very helpful. Testing of wine in the authors' laboratory is performed by EN ISO/IEC: 17025. The results show that z-score lies not outside the range ±2 and this is a chance that the authors' results are actually acceptable.展开更多
