Preparation,Characterization and Stability of Bamboo Leaf Polysaccharide Zein Composite Emulsion Gel
摘要
Abstract
Using bamboo leaf polysaccharide(BLP)and zein(Z)as raw materials,bamboo leaf polysaccharide-zein composite particles(BLP-Z)were synthesized via anti-solvent precipitation method.Subsequently,stable low-oil emulsion gels(BLP-Z/KC)were formulated by incorporating κ-carrageenan(KC).The particle size,microstructure,rheology and stability of the emulsion gel were analyzed.The results demonstrated that with the increase of BLP dosage,the viscosity of emulsion gel increased,which prevented the aggregation of oil droplets after homogenization,and the average particle size of emulsified droplets decreased from 12.67 μm(10%BLP-Z/KC)to 3.59 μm(200%BLP-Z/KC).The formation of robust intermolecular hydrogen bonds between BLP-Z and the polysaccharide chains in KC endowed the composite system with pronounced solid-like behavior and exceptional structural stability.The results showed that the dominant molecular force of BLP-Z/KC was hydrogen bond network,and the hydrogen bond strength was positively correlated with the amount of BLP.BlP-Z/KC exhibited excellent stability during heat treatment at 90℃,freeze-thaw treatment at-20℃,and two-week storage.关键词
