In this study, flaxseed oil nanoemulsions were prepared using flaxseed oil as the embedding material and flaxseed gum as the sole emulsifier. The effects of storage temperature, pH, and NaCl concentration on the stability of the nanoemulsions were investigated. The results showed that temperature significantly influenced the stability, and higher temperatures resulted in decreased stability. The nanoemulsions were relatively stable at pH 5 and 7, but showed poor stability at pH 3 and alkaline conditions. Increasing ionic strength led to unstable aggregation. Overall, the stability of the flaxseed oil nanoemulsion was better at 4 degrees C, pH 5-7, and NaCl <200 mmol/L. These findings provide valuable information for the design and preparation of stable delivery systems for flaxseed oil in various industries.
In this study, flaxseed oil was used as embedding material and flaxseed gum as sole emulsifler to prepare flaxseed oil nanoemulsions. The storage temperature (4-37 degrees C, pH 5.8, 0 mmol/L), pH (3-11, 4 degrees C, 0 mmol/L), NaCl (100-500 mmol/L, pH 5.8, 4 degrees C) on the stability of flaxseed oil nanoemulsions were investigated in terms of particle size, zeta-potential, creaming index, microscopy, rheological characteristics, surface tension, and nano-emulsion color as characterization. The results showed that temperature signiflcantly affected the stability of flaxseed oil nanoemulsions, and the stability decreased with increasing temperature. The characteristics of flaxseed oil nanoemulsion were relatively stable at pH 5 and pH 7, while the stability was poor under pH 3 and alkaline conditions. As the strength of the ionic increased, unstable aggregation occurred (NaCl >200 mmol/L). In conclusion, the stability of flaxseed oil nanoemulsion was better at 4 degrees C, pH 5-7, and NaCl <200 mmol/L. These results provide useful information to facilitate the design and preparation of stable package delivery systems for flaxseed oil in food and other industries.
