摘要： The interaction between high-density lipoprotein hydrolysate hydrolyzed by trypsin (EHT) and carboxymethyl dextrin (CMD) at pH 7.0, and in vitro digestibility of high internal phase emulsions (HIPEs) were studied. The particle size of EHT/CMD mixtures increased from 207.2 nm to 1229.6 nm with increase of the ratio of EHT to CMD from 8:1 to 1:2. The proportion of EHT adsorbed on the surface increased from 60.83 % to 80.81 %, forming thicker interfacial layer, exhibiting higher resistance to centrifugation and ionic strength. And more uniform proton density distribution and shorter relaxation time (T-2) were charactered in HIPEs formed by mixtures. Rheological analysis further proved that CMD could lead to high viscosity, high elasticity, excellent oscillation performance of HIPEs. The spatial and electrostatic repulsion forces reduced the aggregation of oil droplets and promoted the formation of more mixed micelles, improving the bioaccessibility of curcumin. These findings provided theoretical strategies for lipid-soluble nutrients delivery systems.
