ABSTRACT

The development of biodegradable packaging, based on agro-industrial plant products and by-products, can transform waste into products with high added value and reduce the use of conventional nonrenewable packaging. Green-based active packaging has a variety of compounds such as antimicrobials, antioxidants, aromatics, among others. These compounds interact with packaged products to improve food quality and safety and favor the migration of bioactive compounds from the polymeric matrix to food. The interest in the potential hygienic-sanitary benefit of these packages has been intensified during the COVID-19 pandemic, which made the population more aware of the relevant role of packaging for protection and conservation of food. It is estimated that the pandemic scenario expanded food packaging market due to shift in eating habits and an increase in online purchases. The triad health, sustainability, and circular economy is a trend in the development of packaging. It is necessary to minimize the consumption of natural resources, reduce the use of energy, avoid the generation of waste, and emphasize the creation of social and environmental values. These ideas underpin the transition from the emphasis on the more subjective discourse to the emphasis on the more practical method of thinking about the logic of production and use of sustainable packaging. Presently, we briefly review some trends and economic issues related to biodegradable materials for food packaging; the development and application of bio-based active films; some opportunities beyond COVID-19 for food packaging segment; and perspectives in circular economy.

ABSTRACT

The availability of different food products containing bioactive compounds promotes their inclusion in the daily diet of consumers. However, the effective and safe delivery of such products requires certain precautions to ensure their preservation, stability, and bioavailability when consumed. Microencapsulation is a great alternative, which is a method capable of protecting different bioactive compounds, including probiotic cells, prebiotic compounds, and some antioxidant substances such as phenolic compounds, anthocyanins, flavonoids, and vitamins. Therefore, this study aimed to perform a literature review and present different alternatives to make bioactive compounds viable through microencapsulation, increase their stability and viability when applied in different food matrices, and address the existing challenges regarding their effectiveness.(AU)


A oferta de diferentes produtos alimentícios que contenham compostos bioativos facilita a sua inserção na dieta como parte do dia a dia do consumidor. No entanto, para que estes compostos sejam entregues de forma segura e eficaz, o uso de certos meios se torna necessário para garantir sua preservação, estabilidade e biodisponibilidade quando consumidos. Com esta finalidade, apresenta-se como uma grande alterativa a microencapsulação, que é um método capaz de fornecer proteção a diferentes compostos bioativos, que incluem células probióticas, compostos prebióticos, e algumas substâncias antioxidantes como compostos fenólicos, antocianinas, flavonoides, vitaminas, dentre outros e garantir uma melhor efetividade na sua entrega. O objetivo deste trabalho foi realizar uma revisão apresentando formas de viabilizar os compostos bioativos através da microencapsulação, para aumentar sua estabilidade e viabilidade diante da aplicação em diferentes matrizes alimentícias, além de abordar os desafios existentes para a sua efetividade.(AU)
