The aim of this study was investigation of prevention of thermal degradation of the red currant juice anthocyanins by addition of different phenolic compounds (catechol, 4-methyl catechol, catechin, chlorogenic acid and gallic acid). Phenolic compounds were added in 50:1 and 100:1 copigment:pigment molar ratio. Red currant juice samples were heated at 30, 50, 70 and 90 °C for 1 hour. Thermal de...

The self-oscillating flyback converter is a popular circuit for cost-sensitive applications due to its simplicity and low component count. This paper presents self-oscillating fly-back converter for mobile batteries charging applications. The converter is designed to step-down the high voltage input to an acceptable level from 220 VAC to 7VDC. By adding indictor and capacitor the power factor a...

Black currant (Ribes nigrum) has various beneficial properties for human health. In particular, polysaccharide from black currant was found to be an immunostimulating food ingredient and was reported to have antitumor activity in a mouse model. We named it cassis polysaccharide (CAPS). In a previous study, CAPS administration caused tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) pro...

The effect of berry phenolics such as anthocyanins, ellagitannins, and proanthocyanidins from raspberry (Rubus idaeus), black currant (Ribes nigrum), and cranberry (Vaccinium oxycoccus) and byproducts of deoiling processes rich in phenolics such as rapeseed (Brassica rapa L.), camelina (Camelina sativa), and soy (Glycine max L.) as well as scots pine bark (Pinus sylvestris) was investigated in ...

The paper presents the results of use black currant (Ribes nigrum L.) variety Sofya with lignified cuttings solutions nanoparticles biogenic ferrihydrite in two modifications. Colloidal “pure” (Feh) and doped aluminum (Feh_Al) have been tested. research showed that soaking exogenous treatment these can increase rooting rate currant. maximum rhizogenic activity was noted variant - 61.9%, which s...

One of the key parameters in Fluidized Bed reactors is the control of biofilm thickness and configuration. The effect of upflow velocity on performance and biofilm characteristics of an Anaerobic Fluidized Bed Reactor was studied in treating Currant wastewater at various loading rates. The reactor used this study was made of a plexiglass column being 60 mm diameter, 140 cm height, and a volume ...

Presented in this paper is a graphical technique for freshwater and wastewater minimisation in completely batch operations. Water minimisation is achieved through the exploitation of inter- and intra-process water reuse and recycle opportunities. In the context of this paper, a completely batch operation is one in which water reuse or recycle can only be effected either at the start or the end ...
