“…These findings align with those of Mendes et al (2022) where an increase in the concentration of rosella flower extract increased the redness of the resulting edible film. Dehankar et al (2023) stated that a positive a* value means a reddish color, whereas a negative a* value means a greenish color. The control sample (without rosella extract) showed a negative a* value.…”

| Valorisation of whey as an edible film has been extensively studied. This study aimed to evaluate the moisture content, physical properties of color, antioxidant activity, and sensory properties of edible films made from whey with the addition of antioxidants from Rosella calyx extract (Hibiscus sabdariffa L). The edible film was prepared with the addition of four different levels of rosella extracts (0, 0.2, 0.4, and 0.6%). The addition of rosella calyx extract led to a significant difference (P<0.05) in color (redness), antioxidant activity, and color sensory attributes, but did not affect the moisture content, aroma, and flavor (P>0.05). The greater the amount of rosella extract added, the higher the a* value of the color attribute (redness), which gives a deeper red color to the whey edible film. Increasing the concentration of rosella added to the whey edible film also increased antioxidant activity. The use of rosella extract can increase the antioxidant properties (79.60%) of edible films whey and consumer acceptance of color attributes (3.84-like) with the best treatment at an additional concentration of 0.6%.

“…Roselle calyx extract was revealed to have strong antioxidant components such as flavonols, anthocyanins and polyphenolic compounds [9]. The incorporation of RE could be used as an antioxidant and antimicrobial agents for foods packaging to prevent the food spoilage and increase the shelf-life of foods [10].…”

The biodegradable and multifunctional nanocomposite films incorporated with TiO2 nanoparticles (T) and roselle extract (RE) in corn starch (CS) matrix were successfully developed by the solution casting method. The physical and functional properties of bionanocomposite films were comparatively evaluated as well as an analysis of the microstructure of films. The properties of CS film could be significantly altered by incorporating TiO2 and/or RE, and the CSRE, CST and CSTRE films all exhibited improved mechanical properties, higher barrier properties against water vapor and UV light. The composite films containing RE also obtained pH sensitive ability, showing color visibly variations to different pH values. The CSTRE film performance 1.52 times higher tensile strength and 27.1% lower water vapor permeability than CS film accompanying enhanced UV light blocking capacity. Scanning electron microscopy (SEM) appeared more compact and homogeneous microstructure in CSRE and CSTRE films compared to CS film and the Fourier transform infrared (FTIR) spectroscopy and X ray diffraction (XRD) results indicated that there were good interactions between TiO2 nanoparticles, RE and starch molecules. Antioxidant and antimicrobial assays revealed that the antioxidant activity of bionanocomposite films were mainly affected by RE and the antimicrobial impression related to both RE and TiO2. The CSTRE film possessed strong antioxidant activity and exhibited obvious antimicrobial activity against S. aureus and E. coli. It suggested that the multifunctional bionanocomposite films incorporated TiO2 nanoparticles and RE with corn starch could be a potential approach for developing sustainable active food packaging.
