Mucilage from Plantago ovata Forsk seed: Optimization of extraction process conditions and investigation of some functional properties
Abstract Psyllium mucilage was extracted from Plantago ovata Forsk and functional properties were investigated. Concerning this objective, Response Surface Methodology based on a 4-factor 3-level Box-Behnken design was used. The independent variables were as follows: extraction temperature (50-80 °C...

| Summary: | Abstract Psyllium mucilage was extracted from Plantago ovata Forsk and functional properties were investigated. Concerning this objective, Response Surface Methodology based on a 4-factor 3-level Box-Behnken design was used. The independent variables were as follows: extraction temperature (50-80 °C), extraction time (60-120 min), water-to- Psyllium seed ratio (50/1-100/1), and water pH (4-10). On the other hand, the dependent variables were decided as EY (extraction yield), SC (swelling capacity), EC (emulsion capacity), and ES (emulsion stability). Optimum extraction conditions based on numerical optimization were 79.99 °C extraction temperature, 60.02 min extraction time, 99.99:1 water-to-seed ratio, and 7.38 water pH. Within these optimum conditions, 29.54% EY, 25.47 mL g-1 SC, 68.39% EC, and 76.61% ES were predicted. The results indicated that Psyllium mucilage can be used as a promising additive as a stabilizing agent in food formulations. |
