Althaea officinalis L. root mucilage holds promise for food industries due to its functional properties. Despite various extraction techniques, ohmic systems remain underexplored for mucilage extraction. This study aimed to compare the efficacy of mucilage extraction using ohmic systems with maceration and investigate their physicochemical properties. The mucilage extraction was carried out utilizing maceration (M), ohmic-assisted extraction (OAE), and ohmic-assisted vacuum extraction (OAVE). Various parameters were evaluated, such as densities and specific energy consumption. The mucilage obtained by OAE had the highest yield (8.9 %). The highest solubility corresponded to the mucilage obtained by the OAE system (85.18 % at 65 °C). OAVE mucilage had 76.16 % swelling and 82.5 g water/g dry sample binding capacity, while OAE mucilage had 19.6 g water/g dry sample binding capacity. The OAVE mucilage oil absorption (12.3 g oil/g dry sample) was almost twice that of the OAE system. Rheological analysis characterized them as a pseudoplastic behavior. DSC thermogram of mucilage samples exhibited a singular endothermic peak (92.05 to 108.3 °C). FTIR analysis highlighted that the primary constituents of mucilage samples predominantly consisted of polysaccharides. This study concluded that ohmic-assisted extraction was the most efficient method for obtaining mucilage. Further research could explore the potential applications of this mucilage.

Several plant seeds release a mucilaginous envelope through hydration, rich in pectins and stabilized by cellulose fibers. This mucilage aids in seed protection, development, and adhesion for dispersal. This study aimed to separate the effects of pectins and cellulose fibers by using pectinase to remove mucilage pectins, leaving cellulose arrays, and performing wet and dry pull-off force measurements on seeds of three plant species: Salvia hispanica (Chia), Collomia grandiflora (Collomia) and Linum usitatissimum (Flax).

The effect of a mucilage extracted from Opuntia ficus-indica (L.) Mill (OFI) cladodes was tested in lipopolysaccharide (LPS)-challenged HepG2 hepatocarcinoma cells, through a combined in vitro-in silico approach. The OFI mucilage was characterized by gas chromatography-mass spectrometry and liquid chromatography-high resolution mass spectrometry.

Microwave-assisted extraction conditions were optimized using response surface methodology to evaluate the effects of extraction parameters on the yield and carbohydrate content of Luffa aegyptiaca mucilage. Extraction at 540 W for 2 min with a 1:20 (g/mL) was determined as the optimal parameter, resulting in a maximum yield of 5.90 % (w/w) with 63 % carbohydrate content consisting of glucose, galactose, maltose, mannose, and galacturonic acid, with structural linkages of β (1 → 4) and β (1 → 6) glycosidic bonds.

Aims: The sand-fixing desert shrub Artemisia sphaerocephala produces a large amount of seed mucilage, which plays crucial roles in the adaptation of this species to desert environments. Seed mucilage has been shown to be degraded by Phanerochaete chrysosporium from habitat soils, but the process and products of this degradation remain unclear. To fill this gap, we explored the factors and processes involved in mucilage degradation.
