Special Issue Information

Dear Colleagues,

In recent years, the growing consumer awareness toward environmental concerns and legal requirements has driven the quest for more sustainable packaging materials. In this context, the development of polymers that, in addition to their basic function, may have additional properties has become a very appealing study topic for both academia and industry.

Multifunctional polymers are often designed and tuned regarding their composition and structure to reach two or more complementary properties (e.g., antioxidant, antimicrobial, shape memory, and stimuli-responsive). From an industrial viewpoint, these polymers are advantageous because they allow reducing raw material requirements and the volume of waste generated.

On the other hand, food packaging has a crucial function in preserving the quality and safety of foods and extending their shelf life throughout the supply chain. Thus, the demand for active and intelligent food packaging with multifunctional properties (e.g., specific gas barrier, gas or moisture absorbents, UV protection, antioxidant activity, antimicrobial properties, or the ability to monitor and report product quality) has received growing attention in recent years.

In this Special Issue, we encourage the submission of original research manuscripts, short communications, or review articles within this scope. The topics include but are not limited to the following list:

  • Synthesis and characterization of multifunctional polymers for food packaging;
  • Strategies to the design of multifunctional food packaging;
  • Active and intelligent packaging for food applications;
  • Food coatings with multifunctional properties;
  • Bio-inspired multifunctional packaging material.

Edible films based on fruit and vegetable purees combined with different food-grade biopolymeric binding agents (e.g., pectin, gelatin, starch, sodium alginate) are recognized as interesting packaging materials that benefit from the physical, mechanical, and barrier properties of biopolymers as well as the sensory and nutritional properties of purees. In the current contribution, edible antioxidant films based on pear juice and pregelatinized cassava starch were developed. In particular, the suitability of using pregelatinized cassava starch for the non-thermal production of these novel edible films was evaluated. In addition, the effects on the films’ properties derived from the use of pear juice instead of the complete puree, from the content of juice used, and from the carbohydrate composition associated with the ripening of pears were all studied. The produced films were characterized in terms of their total polyphenol content, water sensitivity, and water barrier, optical, mechanical and antioxidant properties. Results showed that the use of pear juice leads to films with enhanced transparency compared with puree-based films, and that juice concentration and carbohydrate composition associated with the degree of fruit ripeness strongly govern the films’ properties. Furthermore, the addition of pregelatinized cassava starch at room temperature discloses a significant and favorable impact on the cohesiveness, lightness, water resistance, and adhesiveness of the pear-juice-based films, which is mainly attributed to the effective interactions established between the starch macromolecules and the juice components.
