Researchers have been focusing increasingly on preparing innovative packaging films made from renewable and biodegradable materials in recent years. This research set out to fabricate analyze pH-sensitive edible based salep mucilage combined with anthocyanin saffron (Crocus sativus L.) (SAAs). A casting technique was developed varying concentrations of SAAs (0, 2.5, 5, 7.5, 10%v/v) films. The s...

introduction:packaging is an important factor in food industry and is dominated by petroleum-derived polymers. therefore, the amount of research involving the production and characterization of biodegradable films has increased substantially, mainly due to interest in minimizing the ecological impact caused by the use of synthetic packaging materials. several biopolymers have been exploited to ...

Grain protein-based films containing mixtures of glycerin and polyethylene glycol (PEG) as plasticizers were prepared and evaluated for water vapor permeability (WVP), tensile strength (TS), and elongation (E). Changes in mechanical properties during storage were also studied. The PEG produced opposite trends in E of wheat gluten and corn-zein films. The TS of wheat gluten films increased and E...

Cereal Chem. 72(1):1-6 Glass transition temperature (Tg) and mechanical and water vapor However, the Tg failed to change with solute composition and exhibited barrier properties of wheat gluten films containing glycerin, sucrose, low correlation with barrier and mechanical properties. Initial addition glycerin-sucrose, and glycerin-sorbitol were studied. Glycerin and sucrose of glycerin increas...

the high hydrophilic property of biopolymer based plastics is one of the most important defects of them. blending biopolymers with compatible synthetic polymers and using nano particles such as nanoclay as nanofiller are improving methods that have been extensively considered in recent years. carboxymethyl cellulose (cmc) is one of the lowest cost biopolymers that have enormous applications in ...
