Abstract

This study utilized citrus peel residue as the raw material and combined the clean label concept to directly prepare citrus peel residue-based nanoparticles (CPN) through mechanical ball milling.CPN was investigated as a Pickering stabilizer for the preparation of sunflower oil/cinnamon essential oil mixed oil phase (50% based on volume) emulsions.The study focused on the effects of different volume ratios of sunflower oil to cinnamon essential oil (S∶C=5∶0-1∶4) in the mixed oil phase on the structure, stability, and antioxidant activity of the emulsions.CPN presented a fibrillar structure of nanocellulose with attached nanocolloidal particles and exhibited good performance as a Pickering stabilizer.As the proportion of cinnamon essential oil in the emulsion increased, the D(4,3) of the emulsion decreased from 113 μm to 50 μm, while the viscosity of the emulsion system increased and its antioxidant activity improved.Additionally, an increase in the proportion of cinnamon essential oil in the oil phase enhanced the pH, temperature, and centrifugal stability of the emulsion, thereby improving the environmental stability of the emulsion.This current research provides a method for preparing natural Pickering stabilizers based on fruit and vegetable peel residues and their application in emulsions.It demonstrates that the structure and stability of emulsions can be regulated by adjusting the composition of the oil phase and the functional emulsions can be effectively prepared by loading cinnamon essential oil.This offers a reference for promoting the high-value utilization of fruit and vegetable peel residues and their application in food emulsions.
