“…Mannans consist of a D-mannose backbone, linked mainly by β1→4 bonds, which can be ramified with other monosaccharide, so originating glucomannan, galactomannan, and galactoglucomannan [ 57 ]. Furthermore, (β1→3)- or (α1→3)-, (β1→2)-, and (β1→6)- or (α1→6)-D-mannosidic bonds are reported [ 56 ].…”

Plant-Derived Nutraceuticals and Immune System Modulation: An Evidence-Based Overview

2020

Immunomodulators are agents able to affect the immune system, by boosting the immune defences to improve the body reaction against infectious or exogenous injuries, or suppressing the abnormal immune response occurring in immune disorders. Moreover, immunoadjuvants can support immune system acting on nonimmune targets, thus improving the immune response. The modulation of inflammatory pathways and microbiome can also contribute to control the immune function. Some plant-based nutraceuticals have been studied as possible immunomodulating agents due to their multiple and pleiotropic effects. Being usually more tolerable than pharmacological treatments, their adjuvant contribution is approached as a desirable nutraceutical strategy. In the present review, the up to date knowledge about the immunomodulating properties of polysaccharides, fatty acids and labdane diterpenes have been analyzed, in order to give scientific basic and clinical evidence to support their practical use. Since promising evidence in preclinical studies, limited and sometimes confusing results have been highlighted in clinical trials, likely due to low methodological quality and lacking standardization. More investigations of high quality and specificity are required to describe in depth the usefulness of these plant-derived nutraceuticals in the immune system modulation, for health promoting and disease preventing purposes.

“…Guar gum is obtained from the ground endosperm of the guar legume (cyamopsis tetragonolobus) 2 , and has a range of uses in the food, cosmetics and pharmaceuticals industries [2][3][4][5][6][7][8] . The galactomannan chains of guar gum are also amenable to copolymerisation, e.g.…”

Guar gum hydrogels may be dried to form polymer films which have the potential for use as biodegradable alternatives to polymers such as low-density polyethylene. In this study, the tensile strength and tensile modulus of guar gel films having moisture contents ranging between 15% and 18% (wet basis) were measured at a strain rate of 1 mm min−1. Mean tensile strengths of the films ranged between 25 MPa and 40 MPa (dependent on composition) which is of similar magnitude to the tensile strength data for polyethylene and cellophane that are reported in the literature. The mean tensile modulus of the films (1.5–2.5 GPa) was higher than the tensile modulus values reported for low-density polyethylene but comparable to those for cellophane (3 GPa).

“…Generally Recognized as Safe (GRAS) labeling or GRAS/FS (some compounds are safe for use in food industry; however, their concentrations is limited by currently used standards). In this respect, the main goal is to avoid toxic, allergic, and/or non-assimilable components [7][8][9][10][11][12][13][14][15]; • Comply with good manufacturing practices (GMP) [16,17];…”

Edible and Functionalized Films/Coatings—Performances and Perspectives

et al. 2020

View full text Add to dashboard Cite

In recent years, food packaging has evolved from an inert and polluting waste that remains after using the product toward an active item that can be consumed along with the food it contains. Edible films and coatings represent a healthy alternative to classic food packaging. Therefore, a significant number of studies have focused on the development of biodegradable enveloping materials based on biopolymers. Animal and vegetal proteins, starch, and chitosan from different sources have been used to prepare adequate packaging for perishable food. Moreover, these edible layers have the ability to carry different active substances such as essential oils—plant extracts containing polyphenols—which bring them considerable antioxidant and antimicrobial activity. This review presents the latest updates on the use of edible films/coatings with different compositions with a focus on natural compounds from plants, and it also includes an assessment of their mechanical and physicochemical features. The plant compounds are essential in many cases for considerable improvement of the organoleptic qualities of embedded food, since they protect the food from different aggressive pathogens. Moreover, some of these useful compounds can be extracted from waste such as pomace, peels etc., which contributes to the sustainable development of this industry.
