“…The further addition of 1% TiO2 to the AG-AN/GG film significantly improve the water barrier ability, as the WVP of AG-AN/GG-1%TiO2 film was 2.93 ± 0.22 g/mm/m 2 /kPa/h. This was probably due to the prolonged tortuous pathway of water vapor formed by the well-distributed water impermeable nanoparticles [45]. Similar results were also found in chitosan-TiO2 blend films [46] and wheat glute-nanocellulose-TiO2 blend films [47].…”

“…The thermal stability of the film and curcumin was tested using a thermogravimetric analyzer (Hi-Res TGA 2950, TA Instrument, New Castle, DE, USA) following the method of Roy et al [ 40 ]. The temperature of the maximum disintegration rate was determined from a derivative form of the TGA (DTG) curve, and the weight loss (%) was calculated from the TGA curve [ 40 ].…”

Curcumin incorporated poly(butylene adipate-co-terephthalate) (PBAT) based film was fabricated. Curcumin has uniformly distributed in the PBAT matrix to form a bright yellow PBAT/curcumin film. The PBAT/curcumin film has slightly reduced tensile strength and flexibility than the neat PBAT film, while the thermal stability of the film has not changed significantly. The blending of curcumin significantly decreased the water vapor permeability of the PBAT film. Additionally, the PBAT/curcumin film showed potent antioxidant activity with some antimicrobial activity. The PBAT/curcumin films with improved water vapor barrier and additional functions can be used for active packaging applications.

“…Escherichia coli O157: H7 ATCC 43895 and Listeria monocytogenes ATCC 15313 were procured from the Korean Collection for Type Culture (KCTC, Seoul, Korea). The copper sulfide nanoparticles (CuSNP) used in this study were prepared as previously reported [ 25 ].…”

“…[ 23 , 24 ]. Recently, some functional films reinforced with CuSNP have been reported [ 15 , 16 , 25 ], and there have been several reports of functional films with added limonene [ 22 , 26 , 27 , 28 ]. Considering the potential of CuSNP and limonene as functional materials, synergies can be expected when these materials are used together.…”

Edible biopolymer (pullulan/carrageenan) based functional composite films were fabricated by the addition of copper sulfide nanoparticles (CuSNP) and D-limonene (DL). The DL and CuSNP were compatible with the pullulan/carrageenan biopolymer matrix. The addition of CuSNP significantly increased the UV-blocking properties without substantially reducing the transparency of the film. The addition of CuSNP improved the film’s tensile strength by 10%; however, the DL addition did not significantly influence the strength, while the combined addition of CuSNP and DL increased the strength by 15%. The addition of the fillers did not significantly affect the thermal stability of the film, but the water vapor barrier property was slightly improved. There was no significant change in the moisture content and hydrophobicity of the composite film. Besides, the composite film showed some antimicrobial activity against food-borne pathogenic bacteria. The fabricated pullulan/carrageenan-based film with antimicrobial and UV-barrier properties is likely to be used in active food packaging applications.
