Pear cubes were dehydrated by convective drying (CD) and by combined method consisting of convective pre-drying (CPD) and vacuum-microwave finish-drying (VMFD). During combined method the time of CPD lasted for 15, 30 and 120 min. The VMFD of pear cubes was performed at magnetrons power of 240, 480 and 720 W. The drying kinetics of pear cubes was described using a modified Page model. The entire drying...
Śliwki należą w Polsce do bardzo popularnych owoców. Są bogatym źródłem związków polifenolowych oraz wyróżniają się wysoką pojemnością przeciwutleniającą. Sezonowa podaż śliwek determinuje ich przetwarzanie. To z kolei wpływa na zmiany jakościowe i ilościowe występujących w nich składników. Suszenie śliwek powoduje zmniejszenie zawartości związków polifenolowych przy jednoczesnym wzroście ich pojemności...
The genetic variability of sessile oak (Quercus petraea L.) mature stand and its natural progeny was investigated. Comparison between genetic structure of parental and progeny trees was based on frequencies of nuclear microsatellite (SSR) alleles occurring in three DNA loci. A slight (4%) increase of gene pool between oak mature and progeny trees was revealed by heterozygosity level estimation, maintaining...
The aim of the study was to assess the impact of modulating factors on vascular smooth muscle cells reactivity. Vascular resistance was induced by the administration of increasing concentrations of imidazole. The experiments were performed on isolated and perfused tail artery of Wistar rats (weight 250 g – 350 g). Rats were been narcotized by urethane (intraperitoneal injection) at a dose of 120 mg/kg,...
