Abstract

High-pressure homogenization (HPH) is a physical modification method that can rapidly reduce the particle size of bamboo shoot dietary fiber (BSDF), but it can lead to agglomeration. Therefore, the effects of the addition of sucrose ester (SE) to alleviate the agglomeration of BSDF during HPH were investigated. Compared with BSDF without added SE, BSDF obtained the smallest particle size (276.5 nm) and highest ζ-Potential (53.6 mV) when SE was 5 g/L. Water-holding capacity, oil-holding capacity, swelling capacity, and b* increased, whereas L* and a* decreased significantly with the addition of SE. The shear stress and viscoelasticity of BSDF solution were minimized when 5 g/L SE was added. SE reduced relative crystallinity and thermal stability of BSDF. SE could effectively alleviate the aggregation of BSDF through the mechanism of electrostatic repulsion. This study highlights an innovative and promising strategy for alleviating the agglomeration behavior of BSDF during HPH treatment.
