“…HHP assisted by Celluclast ® treatment was performed in order to maximize soluble polysaccharides and oligosaccharides due to the prebiotic effect associated to these components [ 6 , 7 , 11 , 32 , 33 ]. Results showed an increase in both, HMWC and LMWC, commensurate to previous analysis performed individually with high pressure or cellulase enzyme.…”

“…Hawken and collaborators in 2018 reported that the third most effective solution for climate change mitigation is reducing food waste [ 5 ]. Accordingly, by-product valorisation might produce economic and health benefits for the society, while using the existing natural resources to develop new value-added products [ 6 ]. In this regard, apple by-product has been determined as an interesting source of bioactive compounds due to its nutritional composition including dietary fibre [ 4 , 6 ].…”

Oppositely, apple pomace, presents a higher water-insoluble carbohydrates amount, namely, hemicellulose and cellulose, than soluble-water carbohydrates quantity [ 6 , 8 ]. However, preclinical studies have demonstrated a positive effect on lipid metabolism and gastrointestinal function of apple by-product, suggesting its potential use as a functional food and/or food additive [ 6 , 9 , 10 , 11 ].…”

Therefore, it would be of industrial interest to develop a resource-efficient process to reintroduce this derived product into the human food chain since, currently, scientists are attempting to synthesize prebiotics on an industrial scale [ 12 ].…”

A novel and green procedure consisting of high hydrostatic pressure (HHP) aided by a commercial cellulase (Celluclast®) has been applied to valorise the apple by-product, a valuable source of dietary fibre but mainly composed by insoluble fibre. Optimal conditions for solubilisation of dietary fibre were first determined at atmospheric pressure as 2% (w/v) of substrate concentration and 20 Endo-Glucanase Units of cellulase. Monitoring of polysaccharides and oligosaccharides released from apple by-product was carried out by means of a newly validated HPLC method with refractive index detector. A synergistic effect was observed when the combined HHP plus cellulase treatment was used. Thus, the application of 200 MPa at 50 °C for 15 min enabled a significant increase in the release of water-soluble polysaccharides (1.8-fold) and oligosaccharides (3.8-fold), as well as a considerable decrease in the time required (up to 120-fold), compared to control at 0.1 MPa. Therefore, this technology could be a promising alternative approach to transform an industrial by-product into a novel rich-in-oligosaccharide food ingredient and a step forward into shaping the world of prebiotics.

BackgroundsIn this research, the effects caused by ultrafine grinding (U), high‐temperature cooking (HTC), microwave (M) and combined treatment (U‐HTC, U‐M) were evaluated on the functional properties and structural characteristics of soluble dietary fiber (SDF) obtained from soybean dregs.ResultsPhysical treatments could increase the extraction yield of SDF and improve the functional properties of SDF. The highest extraction yield (277.15±5.87 g kg ‐1 based on the weight of soybean dregs) and purity (863.37±5.15 g kg ‐1 based on the extract weight) of SDF was found in the sample by U‐M treatment. U‐HTC and U‐M combined treatments significantly improved the water solubility and oil holding capacity of SDF. U‐M treatment significantly increased the ability of SDF to adsorb cholesterol and perform cationic exchange; compared to the control, these abilities were increased by 138.46% and 10.38%, respectively. At pH 2.0, the nitrite ion adsorption capacity (NIAC) of SDF obtained by U‐M combined treatment was 184.55 μg/g, which significantly increased by 32.10% compared with that of the control. The results obtained by X‐ray diffraction and scanning electron microscopy showed that the structure of SDF generated from soybean dregs became coarser and more porous, and the crystallinity decreased after physical treatments.ConclusionCombined physical treatment is an effective way to improve the extracted yield and functional properties of SDF from soybean dregs.This article is protected by copyright.
