Green coffee is a prime source of antioxidants to functional food and nutraceuticals. Arabica Robusta varieties were screened decaffeinated using ethyl lactate extracted with polar solvent obtain chlorogenic acid (CGA) enriched green extract (GCE). The physicochemical qualities (moisture, pH, particle size, color) bioactive compounds (total phenolics, acid, caffeine) GCE assessed. had 12.78 ± 2.1 mg GAE g−1 phenolics 10.98 (CGA). To improve the stability CGA, encapsulated by spray drying...

The implications of climate change for malaria eradication in the 21st century remain poorly resolved. Many studies have focussed on parasite and vector ecology isolation, neglecting interactions between climate, control, socioeconomic environment, including disruptive impact extreme weather. Here we integrate 25 years data burden, control interventions, factors, weather events Africa. Using a geotemporal model linked to an ensemble projections under Shared Socioeconomic Pathway 2-4.5 (SSP...

Nanoencapsulation by spray drying was performed to protect and preserve antioxidant rich dietary polyphenols from green coffee beans. Nano-encapsulation of done using maltodextrin as wall material. The nanoparticles were further characterised zetasizer, differential scanning colorimetry, X-ray diffraction, In vitro gastric intestinal studies storage stability. Optimal obtained at a temperature 125 °C 2:1 Mwall/Mcore ratio (10% w/w maltodextrin), provided better encapsulation yield (40% w/w)...
