Partículas de alginato e pectina produzidas por gelificação iônica e recobertas com proteínas

Abstract

xii used, alginate particles coated with protein maintained physical integrity after intestinal assay, while pectin particles coated with gelatin were destroyed after intestinal assay and damaged when the whey protein or and gelatin: whey protein mixture were used. When protein solubility was used as a parameter in the gastrointestinal in vitro assay, pectin particles coated with gelatin, whey protein and gelatin: whey proteins mixture showed solubility in the gastric environment of 56, 38 and 37% while the coated alginate particle released 32, 12 and 11%, respectively. After passage through the intestinal tract, coated pectin particles released substantially all adsorbed protein content (> 96%). Coated alginate particles released quantities above 82%.
