Structural and Thermal Properties of Faba Bean Starch and Flax Seed Oil Nanoemulsion: Effect of Processing Conditions on Nanoemulsion
STARCH-STARKE(2024)
摘要
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 degrees C), and ionic strengths (0.5, 1, and 2 m), the N3 nanoemulsion demonstrates significantly greater changes in stability. All the samples show excellent structural properties and stability. Overall, the results suggest that faba bean starch-based nanoemulsion shows promise as a stable delivery system for bioactive compounds, but its stability is influenced by pH levels and ionic strengths. Faba bean starch has been isolated and analyzed to assess its suitability for formulating nanoemulsion with flax seed oil. The findings indicate that the nanoemulsion, based on faba bean starch, holds potential as a reliable delivery system for bioactive compounds. image
