“…The solubility values for all samples of the produced films are lower than those reported in literature to similar matrix. For example, Medina‐Jaramillo et al found water solubility for cassava starch–glycerol films incorporated with extracts of green tea ranged from 28 to 30% . The incorporation of 6% of TTO in a cassava starch‐gelatin‐furcellaran‐based films results in a 42% of solubility, a value 2.5 times higher than the solubilities of the present work …”

In the present study, a cassava starch‐glycerol film with reinforcement of Pinus sp. nanofibers (NFC) incorporated with tea tree (Melaleuca alternifolia) essential oil (TTO) were prepared by casting technique. The physical (barrier, mechanical, and optical), structural, and antimicrobial properties of the films were evaluated and compared with the control films. Films with 0.08% TTO exhibited a significant increase in the tensile strength (TS) while films with 1.5% TTO showed a decrease in TS, suggesting a crosslinking effect. The addition of 1.5% TTO reduced the water vapor permeability values in 43% comparing to the control films. Analysis obtained by Fourier transform infrared spectroscopy showed bands related to the interaction between TTO and matrix for films with 1.5% TTO and 0.3% NFC. This film was effective against Staphylococcus aureus and Candida albicans which could be applied for several packaging purposes. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

“…In the presence of TTO there is a repulsion of the water droplets due to the lipid character of the oil. The results in this work were, in general, higher than studies with cassava‐starch‐based films with green tea (63°–68°) and rosemary extract (49°–53°) …”

“…Specifically, natural extracts as well as plasticizers have low molecular weight and can occupy intermolecular spaces among the starch chains, changing molecular organization, and reducing the energy required for molecular chain movement. In this way, films with better flexibility and processability can be obtained …”

Natural extracts are investigated as plasticizers of starch–glycerol biobased films for food coating applications. For this purpose, films with cassava starch, glycerol, and distilled water with and without green tea or basil extracts are obtained by solvent casting. The plasticizing effect of the extracts is confirmed from the films crystalline structure, thermal degradation behavior, glass transition temperature, and tensile properties. Increased mobility of starch chains is the result of a strong interaction between extract components and starch molecules. The Kohlrausch–Williams–Watts (KWW) theoretical modeling, used for the first time to determine the effect of antioxidant components in starch films, also confirms the plasticizing effect of either green tea or basil extracts. In addition, the original luminosity of the starch film is not compromised by the incorporation of the extracts. Moreover, a delay in the starch retrogradation is achieved, making the film more durable and hence, very promising to be used as food coating.

“…The environmental impact of packaging from non‐renewable raw material and the growing concern with the preservation of the environment have generated great interest in replacing synthetic polymers with biodegradable materials. Thus, alternative polymer sources, such as starches, chitosan, proteins, fats, can be used to produce environmentally friendly packaging (Medina‐Jaramillo, Ochoa‐Yepes, Bernal, & Famá, ). Starch has great potential for the production of biodegradable films due to its characteristics, such as low cost, high availability, renewability, completely biodegradable nature, and edible characteristics (Versino, Lopez, Garcia, & Zaritzky, ).…”

The growing concern on environment preservation and the impact of the packaging from the non‐renewable materials improve the interest at biodegradable and active packages development for food applications. The aim was to develop starch films with yerba mate extract (YME) made with water: ethanol (50:50% vol/vol) at 50°C followed by characterization. The YME was applied to the cassava starch films (control, 5, 10, 15, and 20%). The thickness, water vapor permeability (WVP), tensile strength, elongation as well as the Young’s Modulus, water solubility, phenolic compounds, antioxidant activity (DPPH•), color and opacity and sorption isotherms of the films were characterized. The starch films decrease tensile strength, Young’s module and elongation increased as the YME concentration increased. In addition, the sorption isotherms were adjusted to the GAB model (R2 > 0.96). The moisture absorption by the samples of starch films with 5, 10, and 15%, had similar moisture absorption, higher than the control samples. Practical applications In this research, we developed a biodegradable active film with Yerba mate extract (YME), which is in good agreement with the growing concern in the preservation of the environment through minimization of the environmental impact of packaging from the non‐renewable raw material. YME increased the phenolic compounds and antioxidant activity of the starch films. This behavior is good for fatty food applications, since fat acids may undergo oxidative processes and change sensorial and nutritional characteristics; and antioxidants will slow down these reactions. The YME also promoted a plasticizing effect in the cassava starch films, decreasing tensile strength and increasing the elongation. This behavior allows the application of systems that do not need high mechanical efforts.
