Analysis of the apparent solubility of β-carotene solid dispersion prepared using the hot-melt technology. a β-Carotene solid dispersion consisting of β-carotene, PVP, and one of four emulsifiers was dissolved in phosphate buffer solution (pH 6.8). The two-component formulation of β-carotene and PVP was prepared with a weight ratio of 10%:90% β-carotene: PVP. Values are presented as mean ± SD (n = 3); **P < 0.01 versus PVP only. b β-Carotene solid dispersion consisting of β-carotene, PVP, and Suc in different weight ratios were dissolved in phosphate buffer solution (pH 6.8). The β-carotene solubility was analyzed by HPLC following centrifugation and filtration. Values are presented as mean ± SD (n = 3); **P < 0.01 versus a weight ratio of 10%:90% β-carotene: PVP
