Research output: Contribution to journalArticlepeer-review


Four formulations of whey-protein-isolate (WPI) coatings were used to coat chocolate-covered almonds. Two formulations were without lipid and two were with lipid. The 2 WPI formulations without lipid varied in native- as compared with the heat-denatured WPI amount. The 2 WPI formulations with lipid varied in the lipid amount. The shellac formulation consisted of 30% solids, of which 90% was shellac and 10% was propylene glycol. A central location consumer test was carried out for attributes such as overall degree of liking. The results strongly indicate that water-based WPI-lipid coatings can be used as an alternative glaze, with higher consumer acceptance than alcohol-based shellac.
