NEW RESEARCH ARTICLE: Microwave pretreatment to improve extraction efficiency and polyphenol extract richness. Effect on antioxidant bioactivity

Microwave assisted extraction advantages are widely recognised. However, its implementation at an industrial scale is restricted due to microwave limitations. In this work, a microwave pretreatment is proposed as an easy scale-up alternative. The double effect of this pretreatment on extraction yield and on product richness is assessed. Microwaves accelerate the extraction kinetics of most […]

[Paper]: Microwave-assisted extraction of polyphenols from Clinacanthus nutans Lindau medicinal plant: Energy perspective and kinetics modelling

Microwave-assisted extraction (MAE) of polyphenols from medicinal plant, Clinacanthus nutans (C.nutans) was developed. Affecting parameters on the extraction yield of polyphenols such as ethanol concentration, solvent-to-feed ratio (S/F) and energy absorbed were studied. The variations in the effect of ethanol concentration and S/F were also explained in view of energy absorption. Polyphenols yield was found […]

Adding Value to Wheat Bran by Ferulic Acid Extraction

Ferulic acid (FA) is the most abundant phenolic compound in wheat bran, an abundant and underused subproduct from the milling industry. FA shows potential commercial applications in the food, health and cosmetic industry, which is associated mainly to its antioxidant properties. Therefore, FA extraction from wheat bran constitutes a great alternative to add value to […]

Impregnation of herbs oil into organic and inorganic aerogels for drug delivery system

Medicinal herbs have received much attention world-wide for many years as natural drugs for therapeutic purposes. Their high content of phytochemicals such as antioxidant, anti-cancer and anti-inflammatory compounds drives their uses for disease treatment and prevention as well as in chemotherapy application. Conventionally, these plants have been boiled in water or blended with other ingredients […]
