“…During the experimentation process, it was found in the intial process of starting it was getting softer as they were in contact with water and gradually its reduced as the films were absorbing more moisture. The significant influence of combiantion ratios was observed for swelling index of the films [28].…”

In this research communication, taro starch and fenugreek mucilage were used, in four combination ratios, 1:1 (T1),1:2 (T2),1:3 (T3),2:1 (T4), one pure taro starch (To) and one pure fenugreek mucilage (Fo) to develop total six edible films. Films were evaluated on the basis of optical,textural, morphological, microbiological, color and thermal properties. The optical properties such as transparency and opacity found better results in higher taro concentration films i.e. T1 and T4. In color analysis, the chroma values were found in the range of 66.17-78.80 and hue angle values were found in the range of 22.67-33.85, for all the films. Films of pure fenugreek (Fo) and higher concentration ratio of fenugreek (T2 and T3) found highest rupture strength when compared with another film. Thermal conductivity of the films was founded in the range of 0.049-0.099 W/m°K. A least microbial growth of 1.0 × 10 2 ± 0.03 cfu/ml was found in Fo film and maximum microbial growth of 1.5 × 10 2 ± 0.03 cfu/ml was found pure taro starch film (To). SEM (Scanning Electron Microscopy) analysis of films found smooth surface for (To) and (Fo) films when compared to other films. Higher values of water vapour permeability indicated the porous structure,which allowed the water to penetrate inside the films, it was in the range of 1.53-2.79 mg/Pa.s.m 2 × 10-11. The film (To and Fo) found better results for most of the properties. This edible films can be used as a primary packaging material for food products.

“…A full factorial experimental design was performed according to previous studies (Dias et al, 2014; Dias et al, 2019), considering the MMT15A (0; and 1 g·100 g −1 ) and tocopherol (0; 5; 10; and 20 g·100 g −1 ) concentrations as factors (Table 1). The experiment was performed using a completely randomized design with three replications.…”

The development of natural biodegradable polymers to partially or totally replace synthetic polymers may be advantageous in food packaging, mainly when are associated with additional features such as active packaging. This article aimed to evaluate the effect of tocopherol concentration (0, 5, 10, and 20%) and modified montmorillonite clay (MMT15A) nanoparticles (0 and 1%) on the properties of chitosan (CS) films. The addition of tocopherol provided antioxidant activity and improved the thermal stability of the films, and acted as a plasticizer, decreasing the tensile strength, elastic modulus, and glass transition temperature of the films. Although MMT15A and tocopherol did not change the water vapor permeability, an improvement of the mechanical strength and lower equilibrium moisture content was observed when compared to the treatment made with CS alone. Both MMT15A and tocopherol allowed the production of bio‐nanocomposites with thermal, morphological, mechanical, and water‐resistant properties to be used as an antioxidant in packaging materials. Practical Applications The films containing both montmorillonite (MMT15A) and tocopherol presented an improved mechanical strength, thermal stability, and antioxidant activity when compared to the films containing the only tocopherol. Therefore, it was possible to develop antioxidant chitosan films with improved properties using up to 20% tocopherol and MMT15A. At this tocopherol and MMT 15A concentrations, the films may also be used to nutritionally enrich food, adding value to the package and the conditioned product. Furthermore, the films can also be considered edible films with combined properties.

“…Nano-or microencapsulation can be carried out using different carriers to incorporate the active additives. Dias et al [12] demonstrated the antioxidant capacity and the controlled release of α-tocopherol incorporated to montmorillonite by using PCL as the polymer matrix. Sogut et al [8] used chitosan and PCL-based films containing nanocellulose (2% w/w) and grape seed extract to obtain bilayer films for transferring functional polyphenolic compounds in food packaging applications.…”

“…Among various natural active additives, α-tocopherol (TOC) is known to be a potent antioxidant agent and films loaded with this antioxidant have been proved to be effective in retarding lipid oxidation [19][20][21]. This natural additive is authorized as food contact material by EFSA and FDA authorities [22], and it can provide antioxidant/antimicrobial properties to the food product while also stabilizing the polymer matrix during processing [12]. The incorporation of α-tocopherol into different biopolymers, in particular poly(lactic acid) (PLA) [23][24][25][26] and edible polymers such as methylcellulose [27] or chitosan [19], has been reported.…”

Biodegradable Poly(ε-Caprolactone) Active Films Loaded with MSU-X Mesoporous Silica for the Release of α-Tocopherol

In this study, new active PCL (poly(ε-caprolactone)) films containing α-tocopherol (TOC) and MSU-X mesoporous silica were prepared by melt blending. The studied additives were directly incorporated into the polymer matrix or by impregnating TOC into MSU-X silica (PCL-IMP). Thermal, optical, oxygen and water barrier properties as well as oxidation onset parameters, were studied. Films containing MSU-X and/or TOC showed a significant increase in oxidative onset temperature (OOT) and oxidative induction time (OIT), improving thermal stability against materials oxidation by the addition of mesoporous silica and TOC into the polymer matrix. In addition, the effect of MSU-X addition on the migration behaviour of α-tocopherol from active films was investigated at 40 °C using 50% (v/v) ethanol as fatty food simulant, showing PCL-IMP films the lower release content and diffusion coefficient (3.5 × 10−15 cm2 s−1). Moreover, radical scavenging (DPPH and ABTS) and antibacterial activity against E. coli and S. aureus were favoured by the release of α-tocopherol in the developed films. The obtained results have demonstrated the potential of the new PCL-based active formulations for TOC controlled release in antioxidant and antibacterial food packaging applications.
