Authors identified nutritional and clinical risks and investigated their effect on population health in Slovakia within more than the last 40 years. The results were supported by nationally representative, nutrition researches conducted on more than 20 000 people. Simultaneously, the following factors were studied: average lipid blood levels; prevalence of dyslipidaemia, obesity, diabetes mellitus...
W pracy scharakteryzowano aktywność biologiczną ß-glukanów zawartych w grzybach wyższych, szczególnie w boczniaku ostrygowatym. ß-glukany są to naturalne polisacharydy stymulujące układ immunologiczny przede wszystkim poprzez aktywację makrofagów. Ponadto selektywnie obniżają poziom cholesterolu LDL we krwi. W boczniaku ostrygowatym występuje pleuran, który charakteryzuje się wysoką aktywnością biologiczną...
Praca stanowi przegląd już stosowanych oraz będących jeszcze w sferze prób technologicznych nowoczesnych metod pakowania żywności. Omówiono zasady pakowania próżniowego i pakowania z zastosowaniem atmosfery ochronnej produktów suszonych, a także o średniej i dużej wilgotności pochodzących z surowców roślinnych oraz zwierzęcych. Scharakteryzowano aktywne i inteligentne systemy pakowania. Wskazano na...
The aim of our research was to verify selected methods to determine microbial activity during extraction process in term of speed, simplicity and accurancy of the analysis. Indirect methods – enzymatic determination of L-lactic acid, isotachophoretic determination of lactic acid, pH, as well nitrite amounts determination were verified. The results of these methods were compared with those of direct...
Cereal hemicelluloses are plant cell wall polysaccharides which have a great influence on the processing and quality of starch-based food products due to the interactions between these polysaccharides. In this paper the influence of hemicelluloses isolated from non-food sources i.e. 4-O-methylglucuronoxylan from beech wood and arabinoglucuronoxylan from corn cobs on the rheological and pasting properties...
Buckwheat seeds are an important pseudocereal used as flour in baking industry. Also hulls, a waste material produced in the de-hulling process is of certain interest. Hemicelluloses were isolated from buckwheat hulls. They were characterised and shown to be of the glucuronoxylan type. Their effect upon rheological properties of gels of corn starch with varying amount of hemicelluloses (0.3%; 0.5%;...
