“…Compounds such as eugenol, carvacrol, thymol, limonene, geranial and linalool ( Figure 9 ) were used to prepare active food packaging materials based on PLA with antioxidant and antimicrobial properties to extend the shelf-life of products [ 142 , 143 , 144 , 145 , 146 , 147 , 148 , 149 , 150 ]. The versatility of SFE to obtain EOs and terpenes offered a chance to design productive processes of active PLA materials activated with individual terpenes or their mixtures that are up-scalable to obtain green and sustainable industrial processes.…”

“…These could be based on serial dilution and colony counts, like the SR ISO 16649 specific for E. coli [ 101 , 128 ]. The CLSI standard M07 [ 143 , 146 , 159 ] or NCCLS M2-A8 are based on agar disk diffusion [ 91 ]. This type of analysis, largely diffused, was developed in the 1940s to evaluate the antibiotic effect of penicillin.…”

This review describes the state of the art in the field of poly (lactic acid) (PLA)-based materials activated by natural compounds and extracts (active ingredients, AIs) from plant sources for food and biomedical applications. With a multidisciplinary approach, after a description of the synthesis and properties of PLA, special attention was paid to the chemical properties and unconventional extraction technologies of AIs used for PLA activation. Innovative techniques for the incorporation of AIs into PLA; characterization and the antioxidant and antimicrobial properties of the novel materials were discussed. In view of future perspectives, this study has evidenced that some aspects need to be further investigated from joint research between academia and industry, according to the green chemistry principles and circular economy strategy.

“…The authors indicated that a synergistic effect occurred between eugenol (the main volatile active molecules found in CEO) and ZnO, thus allowing the hydrophobic compounds from CEO and Zn cations to penetrate the bacterial cell membrane, provoking their death. Recently, Cinnamomum cassia essential oil (CCEO), eugenol (EEO), and linalool (LEO) were introduced in PLA capsules according to the emulsion solvent evaporation method 240 (Fig. 8).…”

“…Environment and health safety, degradability, encapsulation efficiency, and biocompatibility are some features that biodegradable shells offer for a wide range of products. Natural or synthetic biodegradable polymers including ethyl cellulose [ 24 , 25 ], chitosan [ 26 , 27 ], alginate [ 28 , 29 ], polyacrylamide [ 30 , 31 ], poly(lactic acid) [ 32 , 33 ], copolymers of lactic and glycolic acids [ 34 , 35 ], or polycaprolactone [ 36 , 37 ], have been investigated as MCs shell materials for agrochemicals, drugs, or fragrances. However, their use for isocyanate encapsulation has been poorly explored.…”

Biodegradable Microcapsules of Poly(Butylene Adipate-co-Terephthalate) (PBAT) as Isocyanate Carriers and the Effect of the Process Parameters

et al. 2023

View full text Add to dashboard Cite

Poly(butylene adipate-co-terephthalate) (PBAT), a biodegradable flexible, and tough polymer is herein used, for the first time, to encapsulate and protect isocyanate derivatives. Isocyanates are essential building blocks widely employed in the chemical industry for the production of high-performing materials. Microencapsulation of isocyanates eliminates the risks associated with their direct handling and protects them from moisture. In light of this, and having in mind eco-innovative products and sustainability, we present a straightforward process to encapsulate isophorone diisocyanate (IPDI) using this biodegradable polymer. Spherical and core-shell microcapsules (MCs) were produced by an emulsion system combined with the solvent evaporation method. The MCs present a regular surface, without holes or cracks, with a thin shell and high isocyanate loadings, up to 79 wt%. Additionally, the MCs showed very good isocyanate protection if not dispersed in organic or aqueous solutions. Effects of various process parameters were systematically studied, showing that a higher stirring speed (1000 rpm) and emulsifier amount (2.5 g), as well as a smaller PBAT amount (1.60 g), lead to smaller MCs and narrower size distribution.
