“…Our results showed that ginseng‐SDF exhibited α‐amylase and α‐glucosidase inhibitory activities in a concentration‐dependent manner (Figure 3). Ginseng‐SDF inhibited α‐amylase activity with an IC 50 of 6.70 mg/ml and a maximum inhibition rate of 91.21% (>20 mg/ml, Table 4), which was higher than those of potato SDF and wheat bran SDF (Cheng et al., 2017; Yan et al., 2019). Ginseng‐SDF inhibited α‐glucosidase activity with an IC 50 of 4.89 mg/ml and a maximum inhibition rate of 99.14% (>10 mg/ml, Table 4), which was slightly higher than that of coffee grounds DF (Vázquez‐Sánchez et al., 2018).…”

“…α‐Amylase is responsible for the breakdown of long‐chain carbohydrates, and α‐glucosidase is a necessary enzyme responsible for the digestion from oligosaccharides to monosaccharides in the intestine. Therefore, the α‐amylase and α‐glucosidase inhibitory activities of soluble dietary fiber can significantly inhibit the conversion of blood glucose in animals, inhibit the increase in postprandial blood glucose, and thus, become an effective way to control the blood glucose level of T2DM patients (Yan et al., 2019). Our results showed that ginseng‐SDF exhibited α‐amylase and α‐glucosidase inhibitory activities in a concentration‐dependent manner (Figure 3).…”

“…Ginseng‐SDF inhibited α‐glucosidase activity with an IC 50 of 4.89 mg/ml and a maximum inhibition rate of 99.14% (>10 mg/ml, Table 4), which was slightly higher than that of coffee grounds DF (Vázquez‐Sánchez et al., 2018). A large number of functional groups (e.g., hydroxyl groups), a high‐glucose content (which may form the framework structure of glucan) and a moderate molecular weight (which maintains the active polysaccharide structure) can positively influence the enzymatic inhibitor activity of ginseng‐SDF (Cheng et al., 2017; Yan et al., 2019). The α‐glucosidase inhibitory activity of ginseng‐SDF was higher than its α‐amylase inhibitory activity, which supported the conclusion that plant compounds are moderate α‐amylase inhibitors and strong α‐glucosidase inhibitors (Oboh et al., 2012).…”

Ginseng (Panax ginseng C.A. Meyer) is the most famous edible Chinese herbal medicine. In the present study, soluble dietary fiber of ginseng (ginseng-SDF, 8.98% content) was extracted from ginseng residue, and its physicochemical characterization, structure, and biological activities were studied. Ginseng-SDF was an acidic heteropolysaccharide (uronic acid, 4.42% content) rich in protein, amino acids, and mineral elements. Glucose was its main monosaccharide composition (58.03%). Ginseng-SDF had a porous microstructure, a typical cellulose I structure and a large number of hydroxyl functional groups. These chemical composition and structural characteristics gave ginseng-SDF a good water solubility (98.56%), oil-holding capacity (OHC) (3.01 g/g), and biological activities, as the antioxidant activity (13.35 μM TE/g, 105.17 μM TE/g, 54.20 μM TE/g for DPPH, ABTs, and FRAP assays, respectively), glucose diffusion retardation index (GDRI, 33.33%-7.43%), and α-amylase/αglucosidase inhibitory activities (IC 50 , 6.70 mg/ml, and 4.89 mg/ml, respectively). The results suggested that ginseng residue is a valuable source of functional dietary fiber, and the ginseng-SDF has a potential use in antioxidant and hypoglycemic foods. Practical applications Ginseng has long been popular as a health food in Asia, North America, and Europe. Ginseng residue is rich in polysaccharides, dietary fiber, proteins, and other components, which is also of great research value. However, there are few studies focus on the soluble dietary fiber of ginseng at present. The research shows that ginseng residue is a valuable source of functional dietary fiber. The chemical components and structural characteristics give ginseng-SDF a noteworthy antioxidant activity and enzyme inhibitory activity in vitro. These properties and biological activities indicate that ginseng-SDF has application value in antioxidant and hypoglycemic foods.

Coffee silverskin (CSS), a potential source of soluble dietary fibre (8%-11%), is a major coffee by-product obtained during the coffee roasting process. Ultrasound-assisted extraction (UAE) and microwave-assisted extraction (MAE) have been considered as efficient and economic novel extraction techniques. In this study, UAE, MAE and simultaneous ultrasound-microwave-assisted extraction (UMAE) techniques were investigated for soluble dietary fibre (SDF) extraction from CSS and compared with conventional solvent extraction (CSE). The highest recovery rate of SDF was accomplished by UMAE (42.7 AE 0.4%), which was 1.5-fold, 1.9-fold and 1.2-fold of the recovery rates achieved by CSE, UAE and MAE, respectively. The extraction time of UMAE was 20 min, which was the same as UAE and MAE, and 4.5-fold less than CSE. It implied that the combination of UAE and MAE could enhance the extraction process by increasing the recovery rate as well as by reducing extraction time as compared with CSE or other individual novel extraction methods applied. Nutritional composition and physicochemical characteristics of the SDF extracts from CSS were also investigated in the study.Green extraction of soluble dietary fibre L. Wen et al.

BACKGROUNDWaste cotton flowers, as a by‐product of cotton cultivation, are enriched with bioactive substances that render them a promising natural source of health‐promoting benefits. In this study, ultrasound‐assisted extraction (UAE), subcritical water extraction (SWE), and conventional extraction (CE) approaches were applied to extract bioactive compounds from waste cotton flowers, and the metabolic profiles, bioactive components, antioxidants, and α‐amylase inhibition of different extractions were systematically analyzed and compared.RESULTSIt was observed that UAE and CE extracts had similar metabolic profiles compared with SWE. The flavonoids and amino acids and derivatives were more prone to be extracted by UAE and CE, whereas phenolic acids tended to accumulate in SWE extract. The UAE extract had the highest amounts of total polyphenols (214.07 mg gallic acid equivalents per gram dry weight) and flavonoids (33.23 mg rutin equivalents per gram dry weight) as well as the strongest inhibition on oxidation (IC50 = 10.80 μg mL−1) and α‐amylase activity (IC50 = 0.62 mg mL−1), indicating that chemical composition was closely related to biological activity. Additionally, microstructures and thermal behaviors of the extracts were investigated and highlighted the ability of UAE.CONCLUSIONOverall, it can be concluded that UAE is an efficient, green, and economical extraction method to produce bioactive compounds from cotton flowers, and the UAE extracts could be used in food and medicine industries because of their high antioxidant and α‐amylase inhibitory activity. This study provides a scientific basis for the development and comprehensive utilization of cotton by‐products. © 2023 Society of Chemical Industry.
