Novel rich-in-soluble dietary fiber apple ingredient obtained from the synergistic effect of high hydrostatic pressure aided by Celluclast®

The apple by-product is the remaining solid obtained after fruit processing, mainly constituted by insoluble dietary fiber. However, soluble fiber would be more desirable due to its positive health effects. simultaneous application of high hydrostatic pressure (HHP), namely at 200, 400, and 600 MPa, for 15 30 min holding time, commercial enzyme Celluclast® (92 EGU) allowed a molecular weight carbohydrates solubilisation achieving therefore, safe fiber-rich product. HHP facilitated cell wall accessibility, as it was observed scanning electron microscopy which revealed considerable disruption; whereas, food-grade activity led decrease polysaccharides (MW), in major MW polysaccharide, i.e. HHP-sample: 6.13*104 kDa; + enzyme-sample: 4.26*104 kDa. cost augmentation (p < 0.05) mainly, glucose, uronic acids arabinose. product present greater water retention capacity, oil emulsion activity, increased than eight times compared control. These results support an enhancement technological nutritional qualities, hence could utilised effective functional ingredient.
