Special Issue Information

Dear Colleagues,

Polymers are increasingly becoming essential in the food science and nutrition sectors, with significant applications ranging from food preservation and packaging to the development of functional foods and nutraceuticals. Understanding how polymers interact with biological systems, such as microorganisms, human cells, and food matrices, is key to advancing innovative solutions in these fields.

This Special Issue aims to bring together cutting-edge research that delves into the interaction of polymers—both synthetic and natural—with biotic systems, focusing on their applications in food science, nutrition, and beyond. We welcome submissions that explore these interactions in the context of food safety, quality, functionality, and health benefits.

Topics of interest include, but are not limited to:

  • Polymers in Functional Foods and Nutraceuticals:
    • Role of edible polymers in enhancing the bioavailability of bioactive compounds.
    • Polymer-based carriers for functional ingredients in food systems.
    • Encapsulation techniques using polymers for the protection and controlled release of nutraceuticals and probiotics.
  • Polymeric Encapsulation Systems:
    • Encapsulation of flavors, vitamins, and bioactive ingredients in food products.
    • Application of biopolymer-based nanocarriers for enhanced nutrient delivery.
    • Stability and release mechanisms of encapsulated compounds in the gastrointestinal tract.
  • Polymers in Food Packaging and Preservation:
    • Development of biodegradable and bio-based polymers for sustainable food packaging.
    • Antimicrobial and active packaging polymers and their impact on food safety and shelf life.
    • Barrier properties and interactions of polymeric films with food components.
  • Polymers and Food Waste Valorization:
    • Use of food and agricultural by-products for the development of biopolymers.
    • The role of polymers in food waste utilization and other sustainable applications.
  • Polymers in Nutrient Delivery and Digestion:
    • Impact of polymeric encapsulants on the digestion and absorption of nutrients.
    • Interactions of food-grade polymers with gut microbiota and their influence on human health.
  • Biocompatibility and Safety of Polymers in Food Applications:
    • Toxicity and safety assessments of polymer-based materials in food products.
    • Biocompatibility of polymeric materials in functional foods and nutraceuticals.

This Special Issue aims to provide a comprehensive overview of the latest developments in the polymer-biotic interactions in food science, nutrition, and health, encouraging interdisciplinary collaboration among food scientists, polymer researchers, nutritionists, and biotechnologists.

The need for encapsulation processes in compounds such as procyanidins (PCs) is related to their functional stability, which may limit their application in functional foods. The aim of this study was to evaluate the in vitro digestion of microencapsulated PCs from litchi peel and coffee pulp to determine concentration changes and antioxidant activity. The PCs were extracted, purified, encapsulated, and subjected to in vitro digestion and absorption. Phenolic acids, flavonoids, and PCs were characterized by UPLC-PDA-ESI-QqQ, identifying 27 compounds, including PCs with mean degrees of polymerization (mDP) of 1.2 and 1.7 for lychee and coffee. It was shown that the concentrations of encapsulated PCs were adequately retained during digestion (94.81 ± 4.83 and 90.74 ± 1.77%, lychee and coffee, respectively), with variation in their antioxidant capacity (68.33 ± 2.89 and 77.07 ± 4.59%); however, they showed better results than in their free form. Additionally, litchi PCs showed a higher absorption rate (100%) than coffee PCs (60%). These results allowed us to determine that encapsulation preserves the properties of the PCs and provides better conservation percentages than other studies, which could be a valuable addition to the functional ingredients market, offering greater value to these by-products.
