Product Development #2: Why yogurt gelatin? A refreshing gelatin dessert with sweetened yogurt gelatin and a decorative layer of orange juice gelatin that adds color and a hint of fruity taste
Development of yogurt gelatin TrialResultsSolution 1Both yogurt and juice gelatin were too grainy Did not gel completely Heat liquid to fully dissolve gelatin 2Gelatin was not sweet enough Gelatin too firm and tough Appearance: not a desirable bright color Increase sugar Decrease gelatin Use Pass-O-Guava nectar rather than Mango-Orange nectar 3Fermented smell and taste Yogurt still too tangy Fermentation may be due to guava juice, which ferments quickly – use orange juice for gelatin next time. Also: check pull date Increase sugar in yogurt gelatin.
