The limited degradation of synthetic polymers used in food packaging when discarded in the environment is a major concern for society. Therefore, industry and academia have sought to develop biodegradable and eco-friendly materials for single-use in packaging. An interesting alternative for the food industry is biodegradable polymeric films, which is why different biopolymers have been used in the production of sustainable packaging. It is worth mentioning that the use of biodegradable polymers is one of the most successful innovations in the industry to address issues related to the environment. Among the available raw materials, starch extracted from different renewable sources is very promising for this purpose, due to its abundance, low-cost compared to other polymers and ability to produce non-toxic films. However, when used alone, pure starch has many limitations, which can be overcome by developing a mixture with other polymers (polymer blends), preferably from renewable and biodegradable sources, such as poly(lactic acid) (PLA). In this context, the absence of literature reviews evidencing the results of the application of films in foods led us to write this article, given the importance of polymer blends produced with different types of starch (cassava, corn, pea, potato, rice and wheat) and the PLA matrix. According to the results, it is clear that polymer blends based on PLA/Starch for food packaging are very promising, already being part of the industries solutions, aiming to minimize the large volume of plastic waste of petrochemical origin discarded in nature. Obviously, as with any technology, more research is needed to further improve the performance of the films, and while much research has made great strides, there are still limitations that prevent the commercialization of these materials.

Allophylus edulis (A. St.‐Hil., A. Juss. & Cambess.) Radlk. (Sapindaceae) is an edible plant from the South American biodiversity that is a potential source of bioactive compounds. The mineral content and antioxidant activity of Allophylus edulis leaves were investigated, as well as the composition and the antioxidant activity of the essential oil. The mineral content was determined by ICP – OES and the antioxidant assays were assessed by ABTS, DPPH and FRAP. The essential oil was obtained by hydrodistillation and analyzed by GC/MS. Calcium, potassium, phosphorus, sulfur, and magnesium were the main minerals found in A. edulis leaves. Of the toxic metals that were present, a low level of aluminum was detected. The essential oil of A. edulis has (E)‐nerolidol as major compound and both, the leaves, and the essential oil isolated from the leaves have antioxidant potential. These findings could provide a framework for developing new food and non‐food products with A. edulis leaves.

The overconsumption of nonbiodegradable materials, particularly plastics, has had a significant and detrimental impact on the environment. Advancements in research sector have led to the development of biodegradable materials, namely starch‐based biodegradable films, which have the potential to reduce this environmental impact. Starch is a unique biopolymer with distinctive chemical, physical, mechanical, thermal, and optical properties that make it an attractive alternative to nonbiodegradable and harmful materials. This review paper comprehensively discusses the properties of starch and the techniques involved in transforming native starch into starch‐based films. Further a broad overview of recent research on combining starch with several composites to enhance the physicochemical properties has been discussed herein. In addition, this paper also discusses recent insights into the development of starch‐based composite films and their potential applications in food packaging systems. Future studies must focus on the development of starch composites that strike a balance between different versatile properties of the biopolymer. Additionally, a critical examination of the interactions at the molecular level will help to expand our understanding of this sustainable biopolymer. Ultimately, the findings of this review paper will provide valuable insights for researchers and industry professionals interested in the development and utilization of starch‐based biodegradable films.
