Development of ω-5 and antioxidant enriched bar with pomegranate seed powder

摘要

Pomegranate seed oil (PSO) is a rich source of punicic acid (PA). The seeds were fractionated and 0.15mm fraction of pomegranate seed powder (PSP) was incorporated in bar type product (pomegrain bar). The present study was aimed to see the effects of critical variables, such as %PSP (4.5–75) and temperature (101–158℃) on response variables (PA recovery, total poly phenols, radical-scavenging activity, hardness, color, and overall quality) of pomegrain bar. The experimental design was engendered for optimization of critical variables in response surface methodology. Results predicted that the optimum levels for critical variables are: PSP 55% and temperature 118℃ which resulted in formulation of pomegrain bar having 84% of PA recovery and overall quality comparable with control.
