“…Trichoderma viride , one of filamentous fungus with complete cellulase system, could secrete a large amount of high-activity cellulase with rapid propagation, which had remarkable effects on degrading DF. Our previous studies had demonstrated that Trichoderma viride was of great value in modifying DF by transforming IDF into soluble dietary fiber (SDF). , However, those studies only focused on improving the yield of SDF, but neglected the release of BP during modification process. Furthermore, for elucidating the possible release mechanism from DF, IDF was used as the research objective to rule out the interferences of SDF and free polyphenols …”

This study is aimed at exploring the release of bound polyphenols (BP) from insoluble dietary fiber (IDF) and its mechanism by solid-state fermentation (SSF) via Trichoderma viride. The results indicated that BP released by SSF (5.55 mg GAE/g DW) was significantly higher than by alkaline hydrolysis. In addition, 39 polyphenols and catabolites were detected, and the related biotransformation pathways were speculated. Quantitative analysis showed that SSF released more ferulic acid, p-coumaric acid, and organic acids, which led to advances in antioxidant, α-amylase, and α-glucosidase inhibitory activities. Furthermore, structural characteristics (scanning electron microscopy, X-ray diffraction, thermos gravimetric analysis, and Fourier transform infrared spectroscopy) and dynamic changes of carbohydrate-hydrolyzing enzymes indicated that the destruction of hemicellulose and the secretion of xylanase were vital for releasing BP. Overall, this study demonstrated that SSF was beneficial to release BP from IDF, which could provide insight into utilizing agricultural byproducts in a more natural and economical way.

“…The binding capacity of SDF for heavy metals ions was determined by ICP-MS (7700X, Agilent) according to the method of Avivar, Ferrer, Casas, and Cerda (2012) and Chen et al (2020) with some modifications. SDF (0.1 g) was added into 10 mL of a solution containing 500 μmol/L of the following model solutions: Pb(NO 3 ) 2 , CdSO 4 Á8/3H 2 O, and CuSO 4 .…”

“…All the SDF samples showed broad peaks at 15-28 , and there was a characteristic broad diffraction peak at around 22 (2θ) observed, indicating that SDFs were mainly substances of amorphous regions. DF was divided into relatively loose amorphous regions and crystalline regions, in which the ordered and dense network state is formed connected by intramolecular hydrogen bond(Chen et al, 2020;Sun et al, 2020). The characteristic diffraction peaks of the four SDFs were roughly the same, indicating that the pretreatment of O 3 , US, and O 3 -US did not alter the crystallization type of lemon SDF.…”

“…Hence, DF is widely used in meat, bakery, and dairy products, since it can improve the water retention and gelation ability, keep the color and texture, or improve the health care function of the products (Szafra nska & Sołowiej, 2020;Tao et al, 2014;Zinina et al, 2019). Dietary fiber can be divided into SDF and insoluble dietary fiber (IDF), compared with the IDF, SDF exists better solubility, water or oil holding capacity, binding capacity for heavy metals ions (Chen et al, 2020;Huang, He, Zou, & Liu, 2015;Zhu et al, 2021). However, in the natural plant cell walls, the proportion of SDF is not high (Gan et al, 2020).…”

In this study, the effects of ultrasonic (US), ozone (O 3 ), or ozone-ultrasonic (O 3 -US) pretreatments on the structural and functional properties of soluble dietary fibers (SDFs) obtained from lemon peel were investigated. Scanning electron microscopy observation showed that, US-SDF, O 3 -SDF, and O 3 -US-SDF showed more looser surface and porous characterization, compared to the lemon peel SDF without treatment (untreated-SDF). Pretreatment led to a significant increases of SDFs yield, which increased by 16.70%, 85.44%, and 92.36% for US-SDF, O 3 -SDF, and O 3 -US-SDF, compared to untreated group, respectively. X-ray diffraction results showed that the crystal structure of the pretreated-SDFs was disrupted and possessed lower crystallinity. TGA analysis showed that pretreated-SDFs exhibited lower thermal stability. All three pretreatments led to a redistribution of monosaccharides in SDFs. In addition, functional properties, including water swelling capacity (WSC), water-holding capacity (WHC), oil holding capacity (OHC), and binding capacity of SDF for heavy metals ions (Pb, Cd, and Cu), were enhanced by the three different pretreatment methods. Especially, O 3 -SDF showed the highest hydration ability. Principal component analysis (PCA) showed that untreated-SDF and pretreated-SDFs were effectively distinguished. In summary, our study suggested that the O 3 pretreatment could be used as the ideal pretreatment method for lemon peel SDF, and O 3 -SDF has the greatest potential to be applied as functional ingredients in food products. Practical ApplicationsUltrasonic (US) treatment is one of the green nonthermal technologies, it has been widely used to assist in the extraction of dietary fiber. Ozone (O 3 ) is commonly used in agricultural waste disposal, while O 3 treatment is still in the blank stage in the field of assisting the extraction of dietary fiber, and has great potential for development.In this experiment, the effects of US and O 3 pretreatment on the structural and functional properties of SDFs from lemon peel were studied. The results showed that pretreated-SDFs existed different structural and functional properties compare with the untreated-SDF. And O 3 pretreatment could be used as the ideal pretreatment method for lemon peel SDF.

“…Previous study showed that soluble dietary fiber could balance dietary fiber intake and replenish the essential nutrient element of the human body, which has attracted the attention of researchers ( Sang et al, 2021 ). Compared with the insoluble dietary fiber, orange soluble dietary fiber (OSDF) presented better functional properties, such as fermentability, solubility, and water/oil holding capacity ( Chen et al, 2020 ).…”
