Summary: Carvacrol-loaded halloysite nanotubes (CA-HNTs) compounds were successfully fabricated by encapsulating carvacrol into halloysite nanotubes. The CA-HNTs exhibited high thermal stability and sustained release ability. The zein films containing CA-HNTs showed significant inhibition efficiency against bacteria and prolonged the shelf-life of cherry tomatoes.

Summary: We fabricated Zein/polycaprolactone (PCL) electrospun nanofiber sheets incorporated with beta-caryophyllene loaded into halloysite (HNT) nanotubes, which can serve as an eco-friendly, bioactive food packaging material. The nanofiber sheets showed improved thermal and mechanical performance, reduced water vapor permeability, and exhibited good antioxidant and antibacterial properties. They also demonstrated sustained slow release of beta-caryophyllene and biocompatibility. The fabricated nanofiber sheets showed environmental degradation and effectively preserved the quality of strawberries during storage.

Summary: Antimicrobial food packaging shows great potential in prolonging shelf-life of food and reducing the risk of foodborne diseases. Essential oils (EOs) have emerged as promising natural antimicrobials to be incorporated in polymeric materials. However, commercial use of these packaging systems still faces major barriers including safety, regulation, benefit-cost ratio, and production capabilities.

Summary: A pH-sensitive nanocomposite was synthesized by coating halloysite nanotubes (HNT) with polyacrylic acid (PAA)/carboxymethyl cellulose (CMC) hydrogel for controlled delivery of curcumin (CUR) to MCF-7 cancer cells. Hazelnut oil and Span 80 surfactant were added to minimize the nanocomposite size and increase its uniformity, and to enhance the stability and retention of CUR as an anticancer drug, respectively. The resulting drug delivery system exhibited high drug loading and encapsulation efficiency, pH-sensitivity, and sustained drug release. It also demonstrated strong toxicity against MCF-7 cancer cells and induced apoptosis. These results highlight the potential of PAA/CMC/HNT/CUR hydrogel nanocomposites as smart drug delivery vehicles for breast cancer treatment.

Summary: In this study, composite films based on banana flour were formulated by incorporating halloysite nanoparticles and essential oil carvacrol. The addition of nanoparticles improved the mechanical properties and water vapor barrier properties of the films, while carvacrol demonstrated antimicrobial activity. The incorporation of nanoparticles and carvacrol also resulted in changes in surface morphology and reduced water solubility. The films showed an increase in tensile strength and elastic modulus, and a decrease in water vapor transmission rate. Coating capsicum fruit with the films also improved weight loss and firmness during storage, indicating their potential as natural food packaging materials.

Summary: Using nanocarriers to load antimicrobial agent instead of direct incorporating into film matrix could avoid burst release. Halloysite nanotubes (HNTs) are natural clays with a unique tubular structure; therefore in many studies it served as carriers to achieve a controlled release of active agents. However, when HNTs biocomposites were loaded into packaging film, the antimicrobial activity was reduced too seriously to preserve the packaged food. This study aimed to improving preservation properties of the fabricated films from two perspectives: enlarging the loading capacity of the carrier, and increasing the concentration of HNTs biocomposites.

Summary: The present study demonstrates the incorporation of pectin-functionalised halloysite nanotubes (Pec-f-HNT) into polyvinyl alcohol (PVA) matrix, resulting in polymer nanocomposite films. The modified HNTs and nanocomposite films were characterized using various techniques. The nanocomposite films showed enhanced surface roughness and water behavior compared to plain PVA. The films also exhibited hemocompatibility and were found to promote cell adhesion and proliferation, indicating their potential use in tissue engineering applications.

Summary: Poor mechanical and water barrier properties of protein-based packaging in high-moisture food commodities are improved by incorporating a nanocomposite of tannic acid-loaded halloysite nanotubes grafted with silver nanoparticles. The nanocomposite enhances the tensile strength, thermal stability, and reduces water vapor permeability, oxygen permeability, and water solubility of soy protein isolate (SPI)-based films. Additionally, the nanocomposite exhibits antioxidant properties and reduces microbial contamination in chicken breast fillets.
