“…(2016) with hydrocolloid films. The increased moisture content of these films was maybe because of glycerol's hydrophilic and hygroscopic nature, mainly by free hydroxyl and carboxyl groups leading to higher water‐binding affinity (Sartori et al, 2018).…”

The present study aimed at developing composite edible film from a blend of Ipomoea batatas, κ‐carrageenan, and glycerol. Three different treatments by varying glycerol concentrations (5%‐TS1, 10%‐TS2 & 15%‐TS3) in film‐forming solution were prepared and resultant films were evaluated for rheological, physicomechanical, barrier, and optical properties. All the treatments showed film‐forming ability with varying degrees of distinction. The steady rheology of film‐forming solution containing 10 and 15% glycerol in gel state showed non‐Newtonian fluid behavior. Film solubility improved significantly (p < .01) with glycerol; however water vapor permeability of films had an intermediate value, comparable to other films reported in literature. Mechanical properties of films were excellent in terms of tensile strength, which reached 15 N/mm2. The films presented good optical properties relating to hunter colorimeter. Therefore, the composite blend of I. batatas and κ‐carrageenan can be tailored with glycerol concentration to apply as edible film over different foods. Practical applications The demerits associated with plastics have eventually led researchers' to explore natural alternatives. Edible films are one of the prospering substitutes, but the films prepared from single polymer films are lacking mechanical strength. The composite blend of Ipomoea batatas and κ‐carrageenan is having promising competence to be mold as packaging film with enhanced physicomechanical properties. Glycerol concentration is having an undeviating impact on physicomechanical properties of the film. Therefore, film processing protocol can be stringently controlled to have product‐specific films for practical commercial applications.

“…In the CJP spectrum, the band at 3280 cm −1 corresponds to the -OH stretching vibration of pectin monomers [34], and the band at 2905 cm −1 is associated with methyl groups' stretching vibration of pectin chains [35]. The band at 1740 cm −1 and the band at 1617 cm −1 are related to C=O stretching [36] and -COOH stretching vibration in pectin [35]. The band observed at 1230 cm −1 is related to carboxylic acids' stretching [29].…”

New packaging materials using biopolymers have been studied to substitute synthetic packaging materials that lead to environmental pollution. In this study, a new biodegradable packaging material was developed using the pectin extracted from Citrus junos pomace, which is considered a food processing byproduct. Rambutan peel extract (RPE), at different concentrations (0.25%, 0.5%, and 1.0%), was added as an active material, and the functional properties of the C. junos pectin (CJP) films were evaluated. The incorporation of RPE enhanced the extensibility of the CJP films and their light-blocking ability by decreasing light transmittance. As the concentration of RPE increased, antioxidant activities of the CJP films increased, along with an increase in total phenolic content. Subsequently, the CJP prepared in this study can be used as a low-cost active biodegradable film material, and RPE can be added as a natural antioxidant for the CJP films to confer antioxidant activity.

“…Also, in this case, the values obtained with SCL/zein blends were halfway between the values detected with the films prepared with SCL and zein alone. SCL and SCL/zein blend films are more resistant than those made with porcine plasma proteins (Samsalee & Sothornvit, 2019) and whey protein/pectin composites (Silva et al ., 2018), their mechanical properties being comparable to those detected with the gluten‐based (Sartori et al ., 2018), gelatin‐based and whey protein‐based films (Ghadetaj et al ., 2018).…”
