Special Issue Information

Dear Colleagues,

Dietary fibre is a heterogeneous group that encompasses carbohydrates of diverse chemical (e.g., lignin, inulin, chitosan, β-glucan, etc.) and structural characteristics (from small carbohydrates of 3–9 monomers to large polysaccharides). These carbohydrates have attracted the attention of the scientific community due to their multiple health benefits that could potentially be used to develop healthy functional foods and nutraceuticals. The food industry is aiming to develop novel products “rich in fibre”, as the new definition of dietary fibre includes the demonstration of the health benefits of carbohydrates in order to be considered fibre. Novel carbohydrates can be extracted from vegetal biomass (i.e., terrestrial and aquatic plants), animal sources (e.g., crustaceans) and other under-exploited (for example, algae and fungi) and waste streams from multiple food industries. This proposed Special Issue of Molecules will aim to target recent research papers, reviews, short communications, as well as perspectives in the field of the novel and biologically active carbohydrates. This Special Issue will include research on the use of innovative and emerging technologies, particularly focused on the optimization and implementation of green extraction procedures from multiple natural resources, industrial effluents and waste streams. Among others, manuscripts dealing with purification, characterisation and biological activities “in-vitro” and “ex-vivo” of these carbohydrates, along with their recent applications in emerging fields such as functional foods, animal feed, food supplements, and nutraceuticals based on structural and chemical characteristics, will also be welcomed.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs).

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

(1) Background: In this work, we investigated the application of a natural superdisintegrant, psyllium (Plantago ovata Forsk) husk powder, for the manufacture of orodispersible meloxicam tablets. Meloxicam was chosen as a model compound for the study. (2) Methods: The tablets were prepared using different concentrations of psyllium husk by direct compression. Bulk density, tapped density, hardness, friability, in vitro disintegration, and dissolution time tests were used to assess the quality of the formulations. (3) Results: Psyllium husk powder significantly increased the dissolution rate of meloxicam. The formulation containing 16 mg of psyllium husk powder showed the lowest wetting time, the highest water absorption ratio, and the lowest disintegration time compared to the control and to the other formulations. These effects may be attributed to the rapid uptake of water due to the vigorous swelling ability of psyllium husk powder. (4) Conclusions: The powder could be recommended as an effective natural superdisintegrant for orodispersible formulations. Full article

In order to explore Cassia seed polysaccharides (CSPs) as natural antioxidants for application in the functional-food industry, microwave-assisted extraction (MAE) was optimized for the extraction of CSPs by using a response surface methodology. Furthermore, the chemical structures and antioxidant activities of CSPs extracted by MAE and hot water extraction were investigated and compared. The maximum extraction yield of CSPs extracted by MAE (8.02 ± 0.19%) was obtained at the optimized extraction parameters as follows: microwave power (415 W), extraction time (7.0 min), and ratio of water to raw material (51 mL/g). Additionally, the contents of the uronic acids, molecular weight, ratio of constituent monosaccharides, intrinsic viscosities, and degrees of esterification of CSPs were significantly affected by the MAE method. Moreover, CSPs exhibited remarkable 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) ABTS, 2,2-diphenyl-1-(2,4,6-trinitrophenyl) hydrazyl DPPH, nitric oxide, and hydroxyl radical scavenging activities as well as reducing power. The high antioxidant activities observed in CSPs extracted by MAE could be partially attributed to its low molecular weights and high content of unmethylated galacturonic acid. Results indicate that the MAE method could be an efficient technique for the extraction of CSPs with high antioxidant activity, and CSPs could be further explored as functional food ingredients.

Camellia oleifera is an important Chinese commercial crop. Camellia oleifera can display abnormal leaves due to infection by the parasitic fungus Exobasidium gracile. Exobasidium gracile was isolated from infected leaves and used in fermentation, and exopolysaccharides EP0-1 and EP0.5-1 were purified from the fermentation broth. EP0-1 was an alkaline polysaccharide consisting mainly of the linkages α-d-Manp(1→, →2)-α-d-Manp(1→ and →6)-α-d-Manp(1→, →3)-α-d-Glcp(1→ and→4)-α-d-Glcp(1→, terminal β-d-Galf, (1→5)-β-d-Galf, and terminal β-D-GlcN(1→. EP0.5-1 was an acidic galactofuranose-containing polysaccharide. It contained the linkages of α-d-Manp(1→, →2)-α-d-Manp(1→, →6)-α-d-Manp(1→,→2, 6)-α-d-Manp(1→, →4)-α-d-Glcp(1→, and →4)-α-d-GlcUA(1→. Galactofuranose linkages were composed of terminal β-d-Galf, (1→6)-β-d-Galf and (1→2)-β-d-Galf. Exobasidium gracile exopolysaccharides displayed significant immunoregulatory activity by activating macrophages. This research indicates that infected leaves from Camellia oleifera including the exopolysaccharides produced by the parasitic fungus Exobasidium gracile by are worth further investigation as a functional product.
