Characterization, Antioxidant Activities, and Functional Properties of Mucilage Extracted from Corchorus olitorius L.

Abstract

This study extracted the mucilage from Corchorus olitorius L. to observe its chemical and functional properties and suggest its possible applications in various fields. Corchorus olitorius L. mucilage was isolated by hot water extraction. FT-IR and HPAEC-PAD were used to describe the chemical composition, and the functional properties and antioxidant activities of the mucilage were also examined. The mucilage was mainly composed of uronic acid (34.24%, w/w). The solubility was 79.48 ± 1.08% at 65 °C, the swelling index was 29.01 ± 2.54% at 25 °C, and the water-holding capacity and oil-binding capacity were 28.66 ± 1.48 and 8.423 ± 0.23 g/g, respectively. The mucilage viscosity increased from 4.38 to 154.97 cP in a concentration-dependent manner. Increasing the concentration decreased the emulsion activity and increased the emulsion stability, most likely because of the corresponding increase in surface tension and viscosity. Results from antioxidant assays confirmed that the in-vitro radical scavenging activity of the mucilage increased with concentration. This study shows that C. olitorius L. can be utilized as a new hydrocolloid source, with potential applications in fields ranging from foods to cosmetics and pharmaceuticals.

Antimicrobial Bioactivity and GC-MS Analysis of Different Extracts of Corchorus olitorius L Leaves

“…The traditional medicinal uses of C. olitorius amongst various communities comprise the treatment of heart failure, gastric ulcers, typhoid fever, malaria, gonorrhea, common colds, tumors, and measles [ 10 , 14 ]. The vegetable also has antiviral [ 15 ], antioxidant [ 16 ], gastroprotective, and antidiabetic properties [ 14 , 17 ].…”

Effect of Mucilage Extracted from Corchorus olitorius Leaves on Bovine Serum Albumin (BSA)-Stabilized Oil-in-Water Emulsions

“…Several studies have reported that the leaves have diverse biological activities such as antitumor [ 13 ], antimicrobial [ 14 , 15 ], and antioxidant activity [ 16 ] due to the presence of high amounts of β-carotene, ascorbic acid, lutein, and phenolic compounds such as quercetin [ 17 ]. In addition, C. olitorius leaves contain a large amount of mucilage, which has unique functional properties and bioactive roles [ 18 , 19 ].…”

“…Mucilage is a water-soluble biopolymer that consists of various neutral sugars and uronic. Quantitatively, the predominant component in the C. olitorius L. mucilage was uronic acids, followed by rhamnose, galactose, arabinose, glucose, xylose, and fucose [ 18 ]. However, various factors can influence the monosaccharide composition of mucilage, such as the part of the plant (seed or leaf), cultivation environment conditions, extraction conditions, etc.…”

“…In our previous study, emulsions prepared with mucilage extracted from C. olitorius leaves exhibited a higher emulsion stability index at higher concentrations, although lower than that of xanthan gum. However, there is a limitation in using mucilage alone as an emulsifying agent for long-term emulsion stabilization because mucilage is a hydrophilic polymer with a high molecular weight and low surface activity [ 18 ]. Therefore, in this study, BSA is used as an emulsifying agent in the preparation of emulsion.…”
