“…Recently, the biodegradable film generated from hydrocolloid compounds has received the most attention due to its biodegradability and edible properties. However, the biodegradable films' use is limited by their brittleness and weak resistance to gas exchange [2]. This factor, along with environmental concerns and consumer demands for high quality eco-friendly products related to those found in nature (natural products), has driven the development of new technologies, such as the production of biocomposite films.…”

Food packaging is often made from plastic, which is usually obtained from non-renewable resources. The development of new technologies, like biocomposite films, has been driven in response to environmental concerns as well as consumer demands for eco-friendly, high-quality products derived from nature. Biocomposite films were prepared by incorporating taro mucilage, carboxymethyl cellulose (CMC), ZnO, glycerol, and black cumin seed (BCS) oil. The SEM results showed that the biocomposite films containing taro mucilage (TM), ZnO, and BCS oil had noticeably smoother surfaces. The FTIR analysis indicated the existence of a -OH group, N-H bond, alkaline group, C-C, C=N, C-H, C-O-H, and C-O-C bond formation, confirming the interaction of CMC, glycerol, BCS oil, ZnO nanoparticles, and TM. The results of TGA and DSC analysis suggest that incorporating ZnO nanoparticles, BCS oil, and TM into the CMC polymer matrix increased thermal stability. The addition of TM significantly increased water uptake capacity, antioxidative property, tensile strength, and elongation at break, with significantly decreased whiteness index and water solubility. The film inhibited the growth of Staphylococcus aureus and Escherichia coli as foodborne pathogens. The results suggest that the films can be potentially used as environment-friendly antioxidative and antimicrobial packaging films with additional research.

“…One of the functions of packaging is to provide protection to food, being commonly developed by synthetic polymers, which have good barrier and mechanical properties that promote protection and conservation for food (Santos et al ., 2021). However, synthetic packaging is a material derived from non‐renewable sources, presenting a long deterioration time and, due to incorrect disposal, can increase the effects of several environmental impacts (Martins et al ., 2022).…”

“…Starch is an edible biopolymer obtained from several plant species ( e.g . corn, potato, wheat and cassava), being a low‐cost and renewable source for films development (Martins et al ., 2022). Starch‐based films offer good barrier performances (Roy et al ., 2020); however, the incorporation of composites and essential oils is a strategies used to improve the mechanical properties of starch‐based films (Borges et al ., 2015; Roy et al ., 2020).…”

The incorporation of essential oil and nanocomposites can develop bioplastics with antioxidant and antimicrobial effects that extend the shelf life of food. In this study, active cassava starch films were incorporated with clove essential oil (CEO) and montmorillonite (MMT) for application on fresh strawberries. Central composite design was used in the development of cassava starch active films and the mechanical, barrier, antioxidant and antimicrobial properties were evaluated. The effects of active films on the quality of fresh strawberries were investigated. The incorporation of MMT and CEO promoted better mechanical performance (elongation greater than 180%), greater light barrier properties (opacity greater than 17%) and high antioxidant action due to the content of polyphenols present (32 mg GAE/g). Strawberries packed with the active films showed less changes in the parameters of colour, acidity and microbial contamination during the storage period evaluated.

This study aimed to produce and characterize biodegradable films of sodium alginate incorporated with macaúba pulp extract (MPE‐0, 10%, 20%, and 30%) and evaluate their effects as active sachets containing olive oil. The films were produced by casting technique and mechanical, barrier, and antioxidant properties were evaluated. The incorporation of MPE modified the mechanical, solubility, color, and barrier properties of alginate films. The polyphenol content of the films increased with the addition of MPE, showing antioxidant activity of 4.2 and 4 mg GAE g−1 for ABTS•+ and DPPH, respectively. The film incorporated with 10% of extract (MP10) presented a decrease of 82% in water vapor permeability and an increase in the tensile strength of 2.3 times compared to the control film (without extract). MP10 was used to store olive oil as this formulation showed superior packaging properties compared to the others tested. At the end of the 16 days of olive oil storage, MP10 was able to maintain the quality parameters of peroxide and acidity within the limits established by current legislation. Therefore, these results indicate the great potential of the incorporation of MPE in the elaboration of sustainable and active materials for packaging olive oil and other fatty foods.
