“…(2019) reported negative zeta potential values in the range −20.4 to −14.8 mV for Khorfeh seed gum (Salarbashi et al., 2019). According to the matter that nanoparticles with zeta potential in the range −30 and +30 mV are unstable particles (Razavi et al., 2021; Salarbashi et al., 2019), the higher stability of nanoparticles is related to the particles with Khorfeh wall material. At a higher absolute value of zeta potential, the repulsion between gum macromolecules will be stronger and cause more stability of the nanoemulsion.…”

This study aimed to evaluate the antioxidant activity of free and bound flavonoid or phenolic compounds extracted from the sesame seed (Oltan and Yekta varieties) as natural antioxidants and to demonstrate the properties of nanoparticles. The total phenolic content (TPC) of Oltan was higher (864.70 mg GAE/100 g seed) than that of Yekta (629.23 mg GAE/100 g seed). Oltan took up higher amounts of free (516.86 mg GAE/100 g seed) and bound (347.83 mg GAE/100 g seed) phenolics than Yekta. Also, the Yekta variety exhibited lower amounts of free (45.89 mg CE/100 g seed) and bound flavonoids (21.51 mg CE/100 g seed) and the total flavonoid content (TFC) (67.40 mg CE/100 g seed). Chlorogenic acid was the major phenolic compound present in the sesame seed. In both the DPPH and ferric reducing antioxidant power (FRAP) assays, the highest antioxidant activity was observed in the Oltan variety. Free phenolics showed the highest antioxidant activity, followed by bound phenolics, free and bound flavonoids. Therefore, free phenolics of the Oltan variety were encapsulated in Portulaca oleracea and Trigonella foenum‐graecum seed gums. All nanoparticles showed nanometric size from 236.1 to 680.7 nm, negative zeta potential from −35.4 to −18.3 mV, high encapsulation efficiency from 61.35% to 74.49%, and desirable polydispersity index (PDI) between 0.315 and 0.332. Higher release of phenolics and sedimentation rate were observed in phenolic compounds encapsulated in Khorfeh and Shanbalileh, respectively. The gradual release of phenolic compounds, as well as sedimentation rate of composite coating during 40 days of storage, demonstrated that nanoencapsulated phenolics of sesame within the composite gum coating could be used as natural antioxidants in food systems.

“…Many studies have been carried out on the potential applications of fenugreek mucilage in food, cosmetics and pharmaceuticals, etc. Studies have shown the mucilage to have high viscosity and very good emulsifying properties, probably due to the presence of low concentrations of proteins, making the mucilage suitable for use as a thickener and stabilizer [155,156]. In a study by Memiş et al, biodegradable films were made from fenugreek seed mucilage and nanoclay.…”

The Renaissance of Plant Mucilage in Health Promotion and Industrial Applications: A Review

et al. 2021

View full text Add to dashboard Cite

Plant mucilage is a renewable and cost-effective source of plant-based compounds that are biologically active, biodegradable, biocompatible, nontoxic, and environmentally friendly. Until recently, plant mucilage has been of interest mostly for technological purposes. This review examined both its traditional uses and potential modern applications in a new generation of health-promoting foods, as well as in cosmetics and biomaterials. We explored the nutritional, phytochemical, and pharmacological richness of plant mucilage, with a particular focus on its biological activity. We also highlighted areas where more research is needed in order to understand the full commercial potential of plant mucilage.

“…Mannans, glucomannans, and galactomannans have been previously described as CW storage polysaccharides in several species from diverse families, such as Poaceae, Leguminosae, and Solanaceae (Meier and Reid, 1982;Buckeridge, 2010;Guillon et al, 2012). In fenugreek seeds, galactomannans present at the endosperm CWs play a role as storage components, with a yield of~30% of the seed dry weight (Salarbashi et al, 2019). LeMAN1 has been involved in the mobilization of mannans localized to the lateral endosperm of Solanum lycopersicum seeds, being the hydrolytic product used to nourish the growing embryo (Nonogaki et al, 2000;Lee et al, 2012).…”

A Possible Role of the Aleurone Expressed Gene HvMAN1 in the Hydrolysis of the Cell Wall Mannans of the Starchy Endosperm in Germinating Hordeum vulgare L. Seeds

et al. 2020

The barley endo-b-mannanase (MAN) gene family (HvMAN1-6) has been identified and the expression of its members analyzed throughout different plant organs, and upon grain development and germination. The HvMAN1 gene has been found to be highly expressed in developing and germinating grains. The MAN (EC 3.2.1.78) enzymatic activity gets a maximum in grains at 48 h of germination (post-germination event). Immunolocalization of mannan polymers in grains has revealed the presence of these polysaccharides in the endosperm cell walls (CWs). By mRNA in situ hybridization assays, the HvMAN1 transcripts have been localized to the aleurone layer, but not to the dead starchy endosperm cells. These data suggest that MAN1 is synthesized in the aleurone layer during early grain imbibition and moves potentially through the apoplast to the endosperm where the hydrolysis of the mannan polymers takes place after germination sensu stricto. Hence, mannans in the starchy endosperm CWs, besides their structural function, could be used as reserve compounds upon barley post-germination.
