“…The reduction in particle size was also observed in sample from combination of freeze-thawing and ultrasonication (with the peak at 52 μm and 27 μm). The reduction of particle size could be attributed to the shearing forces from collapse of cavitation bubbles and high-velocity microjets during acoustic cavitation [38] . Numerous studies have also shown that ultrasound treatment led to a decrease in particle size of whey proteins [39] , soy proteins [40] and lupin proteins [41] .…”

Within a biorefinery platform several conversion steps such as pretreatment, saccharification, fermentation and downstream processing are necessary to obtain the final bio-based product(s) from lignocellulosic biomass. The structural composition of the biomass, especially the lignin content, determines the necessary pretreatment steps. To obtain sugar monomers, the hydrolysis of lignocellulosic biomass is an essential step. This work examines the impact of different pretreatments on the sugar release during biocatalysis. Even without prior pretreatment the biocatalysis of low lignin biomass achieves glucose yields of up to 93 %, while the biocatalysis of high lignin biomass requires an upstream hydrothermal procedure to achieve a glucose yield of 74 %.

“…Among these alterations, a decrease in particle size of cellulose powder always accompanied by a significant increase in WHC, OHC, cholesterol adsorption and pancreatic lipase inhibition capacities. Because the decreased particle size can lead to an increase in surface area as well as the exposure of more hydrophilic and lipophilic groups, resulting in the increased binding ability of cellulose (Chen et al, 2013; Csiszar et al, 2021; Zheng et al, 2022). Therefore, the smaller particle size of MCC‐F seems to be much related with its better WHC, OHC and adsorption capacity when compared with MCC‐H.…”

In this study, physicochemical and structural properties of microcrystaline cellulose (MCC) from pomelo fruitlets using different drying methods were analyzed and compared with commercial MCC. The results showed that oil‐holding capacity (OHC), water‐holding capacity (WHC), swelling properties, cholesterol adsorption capacity, and pancreatic lipase inhibition of MCC from pomelo fruitlets especially using freeze drying were higher than those of commercial MCC (p < .05), indicating their better application properties in food processing and functional activity in gastrointestinal health. Through freeze drying, the decreased particle size and crystallinity were much related with its better OHC, WHC, swelling properties, and cholesterol adsorption capacity when compared to that using hot‐air drying. The reduction effect of freeze‐drying on thermal stability of MCC might be caused by the decreased crystallinity. Overall, MCC from pomelo fruitlets especially with freeze‐drying had higher OHC, hydration property, and potential hypolipidemic activity, suggesting its potential applications in pharmaceuticals and food industry. Practical applications This study investigated physicochemical and structural properties of MCC from pomelo fruitlets using different drying methods and compared it with those of commercialized MCC. It was suggested that MCC from pomelo fruitlets especially with freeze‐drying had higher OHC, hydration property, and potential hypolipidemic activity than those of commercial MCC. The results can provide comprehensive evaluation on high‐value application of pomelo fruitlets to produce MCC with desirable properties.
