Resumo
This study was carried out to evaluate the effects of different mixtures of carrier agents (CA) (modified starch-MS plus whey protein concentrate-WPC or soy protein isolate-SPI) on the characteristics of microcapsules containing spray-dried jussara pulp powder. Four treatments, 30%CAC+17.5%MS:WPC, 17.5%CAC+30%MS:WPC, 30%CAC+17.5%MS:SPI and 17.5%CAC+30%MS:SPI, were evaluated, where CAC=carrier agent concentration (g carrier/g jussara pulp solids) and the proportions MS:WPC and MS:SPI indicate the grams of protein (WPC or SPI) per 100g of carrier. The solubility of the particles was not affected by the wall material, attaining average values of 78%. The concentration of 30%CAC+17.5%MS:WPC improved the bulk density and moisture content. WPC and SPI were shown to be good alternative secondary wall materials for jussara pulp, together with MS.
