Optimization of extraction of stinging nettle leaf phenolic compounds using response surface methodology
(Elsevier, Amsterdam, 2015)
A full three level factorial design was implemented for optimization of extraction parameters in order to maximize total phenolic (TP) yield from stinging nettle leaf. Factors considered were percentage of methanol in ...
Influence of common juniper berries pretreatment on the essential oil yield, chemical composition and extraction kinetics of classical and microwave assisted hydrodistillation
(Elsevier Science Bv, Amsterdam, 2018)
The present paper dealt with the influence of the common juniper berries pretreatment on the yield, chemical composition and extraction kinetics of juniper essential oil (JEO) obtained by classical (HD) and microwave ...
Controlled enzymatic hydrolysis for improved exploitation of the antioxidant potential of wheat gluten
(Elsevier Science Bv, Amsterdam, 2017)
The aim of the study was to find the optimal operational and process parameters for the enzymatic hydrolysis of wheat gluten in a batch stirred bioreactor regarding both degree of hydrolysis and antioxidant capacity of the ...
Lactic acid production on molasses enriched potato stillage by Lactobacillus paracasei immobilized onto agro-industrial waste supports
(Elsevier Science Bv, Amsterdam, 2018)
In this study, the production of lactic acid (LA) on sugar beet molasses enriched potato stillage by immobilized Lactobacillus paracasei NRRL B-4564 was examined. Three agro-industrial materials, such as sunflower seed ...
Optimisation of microwave-assisted extraction parameters for antioxidants from waste Achillea millefolium dust
(Elsevier Science Bv, Amsterdam, 2015)
Microwave-assisted extraction of polyphenols and flavonoids from waste Achillea millefolium (yarrow) dust was optimised using the response surface methodology. The influence of the extraction time (13-47 s), ethanol ...
The impact of high-power ultrasound and microwave on the phenolic acid profile and antioxidant activity of the extract from yellow soybean seeds
(Elsevier Science Bv, Amsterdam, 2018)
The aim of the study was to investigate and compare several extraction protocols like 1) high-power ultrasound probe assisted solvent extraction; 2) microwave assisted solvent extraction; 3) direct acid hydrolysis; 4) ...
Improvement of supercritical CO2 and n-hexane extraction of wild growing pomegranate seed oil by microwave pretreatment
(Elsevier, Amsterdam, 2017)
Microwave radiation was suggested as a pretreatment technique to increase the yield of pomegranate seed oil. Seeds were pretreated at 100, 250 and 600 W during 2 and 6 min and then extracted by supercritical carbon dioxide ...
Sorption and dielectric properties of jute woven fabrics: Effect of chemical composition
(Elsevier B.V., 2019)
The jute woven fabric was treated with sodium hydroxide and sodium chlorite under different conditions in order to study the influence of the chemical composition on their sorption and dielectric properties. After the ...
Effect of hemicelluloses and lignin on the sorption and electric properties of hemp fibers
(Elsevier Science Bv, Amsterdam, 2010)
This study investigated the influence of hemicelluloses and lignin removal on the sorption and electric properties, as well as fineness of hemp fibers. Hemp fibers with different content of either hemicelluloses or lignin ...
