Abstract
Nanoemulsions derived from unconventional polysaccharides have gained attention as efficient delivery systems for bioactive compounds, helping in their enhanced absorption. Nontraditional sources of starch have been investigated in recent years due to their potential applications. Therefore, this study investigates the potential of extracting starch from faba beans and investigating their structural properties. Furthermore, the nanoemulsion is developed from starch, flax seed oil, and tween 80 and evaluated for different processing methods (temperature, pH, and NaCl). The extracted starch yields 31.20 g/100 g and X‐ray diffraction reveals its semicrystalline structure. The optimized nanoemulsion (N3) has an average droplet size of 108.62 ± 2.78 nm and a surface charge of −27.74 ± 0.12 mV. At different pH levels (2–9), temperature (30, 50, 70, and 90 °C), and ionic strengths (0.5, 1, and 2
