Improving quercetin dissolution and bioaccessibility with reduced crystallite sizes through media milling technique Muwen Lu, Chi-Tang Ho, Qingrong Huang Abstract Quercetin (QC) is a common bioflavonoid with low water solubility, which limits its oral bioavailability and in vivo beneficial functions. To enhance QC bioaccessibility, QC nanoparticles were produced using the media milling technology. Hydrophobically modified… Continue reading Improving quercetin dissolution and bioaccessibility with reduced crystallite sizes through media milling technique
