- Abstract
As by-product of grape juice and wine production, grape seeds are a rich source of procyanidins. In this study procyanidins were extracted from the residue of grape seeds (oil was extracted by supercritical fluid extraction) with 68.3% ethanol containing 0.8% acetic acid for three times, each 60 rain. The total yield was 98.26% when grape seeds residue to solvent ratio was controlled at 1:8 (W/V). The study on procyanidins microencapsulation using arabic gum and maltodextrin as wall materials (the content of arabic gum is 40%) showed when the ratio of core substance to wall material was 30:70 (W/W) and the content of the slurry was 20% (W/V), the productivity and efficiency of spray dried procyanidins microencapsulation was up to 88.84% and 99.2%, respectively. The UV-spectra of procyanidin was not changed during the processing, indicating its stability was sharply increased.
