The study the quality of not preserved meads and the impact of storage on physicochemical and sensory parameters were evaluated. Triple meads were prepared in 3 variants: kowienski (no additives), hopped (with Saaz hops) and with addition of cranberry juice (Vaccinium oxycoccus). For comparison triple mead available on Polish market was tested. In analyzed samples a positive effect of maturation on physicochemical parameters (content of: ethanol, glycerol, 5-hydroxymethylofurfural and sugars) was found. The highest concentrations of ethanol and glycerol were obtained in samples subjected to maturation. Maturation resulted in a significant improvement in the organoleptic characteristics, evaluated in accordance with the Polish standard PN-A-79120-02:1190.

Sugar beet vinasse, a by-product of ethanol production from sugar beet molasses. Due to its characteristics it is difficult for utilization and it requires treatment, mainly decolorization, before any application. The aim of this study was to separate vinasse colorants using Sephadex G-25 and G-50 column. The effect of vinasse pH on separation was also studied. It was not possible to determine which peak on chromatograms A475 corresponds to the maximum content of melanoidins, caramels or products of alkaline degradation of invert sugar. The number of peaks on each chromatogram was related to the pH value of vinasse. The best conditions for colorants separation was Sephadex G-50 and vinasse pH of 7,0. The gel separation of colorants will enable the identification of intermediates, especially those toxic, so it will enable new possibilities for vinasse utilization.

Nowadays cancer is the leading cause of death in more economically developed countries. Cancer chemoprevention is a term used to describe application of substances to stop or impede the development of cancer. As is well known, the diet rich in fruit, vegetables and spices exhibits these properties. Numerous phytochemicals derived from edible plants have been reported to interfere with a specific stage of the carcinogenic process. Recent studies show that β-ionone found in many plants may be a potential anticancer agent. Until now it has been mainly used the in perfumery-cosmetic industry This review describes the anticancer activity of β-ionone demonstrated against a wide variety of tumors and is based on numerous in vitro and in vivo experiments. High efficiency of β-ionone gives hope for its broader application in prevention and treatment of cancer.
