“…In compliance with the antimicrobial properties of anthocyanins and other phytochemicals, with the release of DIE from the film matrix, the film demonstrated a clear inhibitory action on S. aureus, up to 4.9 logs CFU/mL. Such films can be used as a coating material in fresh fruits and vegetables to extend their microbial safety [170]. Additionally, because anthocyanins can change their chemical structures and exhibit different colors depending on pH, anthocyanin-rich films can be used to evaluate the quality of packaged foods [171].…”

Anthocyanins, the colored water-soluble pigments, have increasingly drawn the attention of researchers for their novel applications. The sources of anthocyanin are highly diverse, and it can be easily extracted. The unique biodiversity of the Himalayan Mountain range is an excellent source of anthocyanin, but it is not completely explored. Numerous attempts have been made to study the phytochemical aspects of different Himalayan plants. The distinct flora of the Himalayas can serve as a potential source of anthocyanins for the food industry. In this context, this review is an overview of the phytochemical studies conducted on Himalayan plants for the estimation of anthocyanins. For that, many articles have been studied to conclude that plants (such as Berberis asiatica, Morus alba, Ficus palmata, Begonia xanthina, Begonia palmata, Fragaria nubicola, etc.) contain significant amounts of anthocyanin. The application of Himalayan anthocyanin in nutraceuticals, food colorants, and intelligent packaging films have also been briefly debated. This review creates a path for further research on Himalayan plants as a potential source of anthocyanins and their sustainable utilization in the food systems.

“…The peak at 1629 cm −1 could be regarded as an asymmetric stretching vibration of COO − [20]. This peak exhibited a blue shift, suggesting that AFE was effectively bound to the film matrix as its addition increased [24]. The peak at 1024 cm −1 could be attributed to the stretching vibration of C-O.…”

To meet the demand for biobased packaging and minimize the oxidation of dried aquatic goods during storage, we created a triple-layer film (TF) with antioxidant capacity. The film was produced using polyvinyl alcohol (PVA) as the protective layer, gellan gum (GG)/PVA composite incorporating Alhagi sparsifolia flower extract (AFE) as the anti-oxidative capability layer, and GG as the anti-oxidative capacity slow-release control layer. The TFs with different AFE additions were characterized and compared to a single-layer film (SF) made of the same material. The results demonstrate that adding AFE to films degraded their water vapour and oxygen barrier properties as well as their tensile strength, but increased their light barrier properties, elongation at break, and anti-oxidative capability. The three-layer structure increased the light, water vapour, and oxygen barrier qualities of films, as well as their slow-release anti-oxidative capability. The application experiment revealed that the inclusion of AFE might aid in the preservation of dried prawn quality. Using TF supplemented with 5 (w/v) AFE to package the dried shrimps reduced the TBARS value by 47.5%. Our research indicated that TFs containing AFE have a wide range of possible applications in dried shrimp preservation.

“…In addition, the incorporation of natural extracts and nanomaterials has been investigated in chitosan-based films. The resulting films had improved antimicrobial activity [83], however, the shelf-life results are not conclusive, and it is unclear if the addition of natural extracts or nanoparticles can extend the strawberries' shelf life when compared with chitosan-based films (Table 2) [83,[85][86][87]96].…”

Strawberry (Fragaria × ananassa) is a valuable crop cultivated worldwide. This fruit is mainly consumed fresh and is an important source of vitamin C, fat‐soluble vitamins and carotenoids. However, fresh strawberries (FS) have a limited shelf life. Conventionally, the shelf life of FS has been extended using refrigeration coupled with modified atmosphere packaging (MAP) technology in traditional petroleum‐based polymeric films. Nonetheless, other packaging technologies such as biopolymeric packaging films and edible coatings can also be used to preserve FS with the advantage of presenting similar shelf‐life extension with lower environmental impact. This review article focused on the analysis of the main factors limiting FS' shelf life, as well as a critical discussion about the use of different packaging technologies as alternatives to increasing FS' shelf life. The revised literature revealed that FS are susceptible to microbial deterioration, weight loss and sensory quality decay. Traditional MAP technology can extend the shelf life of FS to 15 days, depending on the gas composition and storage temperature. Meanwhile, active biopolymeric films and edible coatings can be used as emerging alternatives to extend the shelf life of FS. In general, most studies have produced active films and coatings with the objective of reducing microbial growth, weight loss and sensory quality decay of strawberries during storage. Biopolymeric films and edible coatings applied in strawberries can increase the shelf life of these fruits to a similar extent as traditional MAP. The combination of MAP with biopolymeric films and edible coatings could be explored as an alternative to increase the shelf life of FS.
