Thyme Essential oils (EO) with antimicrobial and antioxidant properties are widely used in pharmaceutical, cosmetic, and perfume industry. It is also used for flavoring and preservation of several foods. Nowadays, packaging research is receiving a considerable attention due to the development of eco-friendly materials made from natural polymers such as starch and chitosan. In this study Thymus ...

The physical and chemical properties of composite starch-based films containing cellulosic fiber, chitosan, and gelatin were investigated. Films containing both cellulosic fibers and chitosan demonstrated tremendous enhancements in film strength and gas permeation. The water absorbency of composite films could be greatly reduced in film composites containing cellulosic fibers and gelatin, but t...

in this study, antimicrobial effects of zataria multiflora boiss added to sodium caseinate film on four bacterial species: staphylococcus aurous, escherichia coli, bacillus subtilis and salmonella intertidis was investigated. disk diffusion method was used to study the antimicrobial activity of zataria multiflora boiss in sodium caseinate film. 9 mm disks were prepared from produced films with ...

pollution arising from plastic waste materials caused a great worry for researchers who are interested in protection of environment. this problem shifts their subject to bio-polymers for applications in packaging industries. however, their low water barrier properties are a critical problem. the effects of citric acid and methyl cellulose on water vapor and oxygen permeabilities and mechanical ...

Background and Objectives: Studies on packaged food by activated biopolymer starch films containing antimicrobial material is interesting field of food. Science This study investigates the effect of chitosan and rosemary essential oil on properties of starch films and peanut were packaged in them. Materials and Methods: In this study, composite films based on starch containing 0, 2, 4, 6 and...

Objective(s): Application of eco-friendly materials like poly lactic acid (PLA) is increasing, to reduce environmental pollutions. In this research, the effect of silicon dioxide 1%, 3% and 5% nanoparticles on morphological, mechanical and chemicals interaction (FTIR) of PLA film was studied. Materials and Methods: Scanning electron microscope (SEM) was used, ...

Today, the economic consumption of biodegradable polymers is of capital importance in many applications. One of the most commonly used biopolymers is polylactic acid (PLA). The printability of the biodegradable film has not been fully investigated. This work tested the printability of polylactic acid (PLA) films and compared the print qualities to common packaging films like low density pol...

Objective(s): Biodegradable film is widely used because it is free from synthetic substances and does not lead to environment pollution. This study aimed to prepare and characterize biodegradable sago starch films loaded with Carboxymethyl Cellulose nanoparticles. Methods: Sago starch films were prepared and plasticized with sorbitol/ glycerol by t...

In recent years, application of nanotechnology in the food packaging industry has become more widespread and is progressively being commercialized. Adding nano-materials improves polymers` barrier properties for gases such as O2 and Co2, and increases UV rays barrier, mechanical strength, stiffness, stability, and heat resistance of the base polymer. In this study, low density polyethylene film...

Background: Edible film is a food packaging that can be eaten directly and have protection function of outside contamination. The purpose of this research is to know how about the effect of using a glycerol plasticizer to film whey-konjac edible films that enriched with clove essential oil. Methods: A completely randomized design was used by different clove essential oil including P10, 0% clov...
