Antibacterial activity of polyvinyl alcohol (PVA)/ε-polylysine packaging films and the effect on longan fruit Ciênc. Tecnol. Aliment.
LI,Yana; WANG,Yuwen; LI,Juying.
Abstract Biodegradable and antimicrobial films via combing ε-polylysine (ε-PL) and polyvinyl alcohol (PVA) is a promising material for food packaging. We prepared the ε-PL/ PVA films with the ε-PL content of 0%, 1%, 3%, 5% and 7% (wt., relative to PVA) by casting method and their physical and chemical properties were characterized. SEM indicated the surface of ε-PL/PVA films was smooth with well compatibility between ε-PL and PVA at the ε-PL addition content of 1%. The tensile strength and barrier properties for water vapor and oxygen of the ε-PL/PVA films initially elevated and then decreased when ε-PL content exceeded 1%. The ε-PL doped endows antibacterial activity of PVA and the antibacterial property of ε-PL/PVA films was increasing with increase of...

Application of silver nanoparticles in food packages: a review Ciênc. Tecnol. Aliment.
SIMBINE,Emelda Orlando; RODRIGUES,Larissa da Cunha; LAPA-GUIMARÃES,Judite; KAMIMURA,Eliana Setsuko; CORASSIN,Carlos Humberto; OLIVEIRA,Carlos Augusto Fernandes de.
Abstract Silver nanoparticles (AgNPs) are antimicrobial agents that have a wide spectrum of action, including against pathogenic bacteria and spoilage fungi. However, their mechanism of action is not completely clarified. Nowadays, scientific interest on biological synthesis of AgNPs is growing, with emphasis in their extracellular biosynthesis by microbial cells, as it is the most reliable and ecologically correct method for production, yielding no toxic residues. AgNPs may be incorporated to biodegradable and non-biodegradable polymers for the production of food packages with antimicrobial properties, leading to greater safety and longer shelf life. However, it is important to carry out migration tests for new food packages incorporated with AgNPs, based...

OTHMAN,Siti Hajar; MAJID,Noorasyikin Abd; TAWAKKAL,Intan Syafinaz Mohammed Amin; BASHA,Roseliza Kadir; NORDIN,Norhazirah; SHAPI’I,Ruzanna Ahmad.
Abstract This work is directed towards developing biodegradable films from biopolymer that is sustainable and environmentally friendly particularly tapioca starch (TPS) films. However, the usage of TPS films for food packaging application has been limited due to the poor mechanical, barrier and thermal properties. Microcrystalline cellulose (MCC) at different concentrations (0 to 10 wt.%) was incorporated as the filler into the films to form TPS/MCC composite films via solvent casting method in order to improve the limited properties of the films. The TPS/MCC films were characterized in terms of physical, mechanical, barrier, and thermal properties. It was found that 3 wt.% MCC was the ideal concentration of filler that resulted to the highest performance...

Water sorption and water permeability properties of edible film made from potato peel waste Ciênc. Tecnol. Aliment.
OTHMAN,Siti Hajar; EDWAL,Siti Amirah Mohammad; RISYON,Nazratul Putri; BASHA,Roseliza Kadir; A. TALIB,Rosnita.
Abstract The water sorption and permeability properties of edible film produced from potato peel waste was investigated under different levels of relative humidity (23, 33, 43, 57, 75% RH) and temperatures (5, 30, 50 °C). The water sorption behaviour and isotherms of the film were investigated by fitting water sorption data to the Peleg model and the Guggenheim, Anderson de Boer model (GAB model). The amount of moisture content, time required for the moisture content of the film to reach equilibrium, water sorption rate, and water sorption capacity increased when the relative humidity increased. The effect of temperature on moisture content, water sorption rate, water sorption capacity, and monolayer moisture content is complex and related to the water...
