Photochromic biodegradable film based on polyvinyl alcohol modified with silver chloride nanoparticles and spirulina; investigation of physicochemical, antimicrobial and optical properties.

In this study, biodegradable film was prepared from polyvinyl alcohol (PVA), Silver chloride (AgCl) and spirulina (Sp). Surface morphology, mechanical properties, antioxidant, antimicrobial, optical properties, etc. were investigated.

Application of cellulose plate modified with encapsulated Cinnamomum zelanicum essential oil in active packaging of walnut kernel.

In this study, Cinnamomum zelanicum essential oil was encapsulated with β-cyclodextrin and sodium caseinate (EO/BCD/Ca) and nanoemulsion was optained. In order to encapsulation of essential oil, different formulations of nanoemulsions containing essential oil were produced by ultrasound method and the effect of different polymers on the particle size and turbidity of the nanoemulsion was investigated. Scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR) techniques were used to study the structure and morphology of the produced nanoemulsions.

Smart film based on chitosan/Melissa officinalis essences/ pomegranate peel extract to detect cream cheeses spoilage.

Antibacterial/biodegradable film based on Chitosan (CS)/pomegranate peel extract (PPE) and Essences (MOE) was prepared. To study the effects of PPE and MOE on the film characteristics, a central composite design (CCD) was used. The physicochemical characteristics of the film, including moisture, water vapour permeability (WVP), antioxidant activity, microbial properties, FT-IR/SEM/XRED spectrum, etc.
