Health and environmental concerns due to usage of synthetic active materials in foods and packaging technologies have increased the demands of using natural additives and the researchers conducted in this area. The purpose of this study is to obtain stable nanoemulsions (NEs)/micro emulsions (MEs) which are formed by using cinnamon oil that has high antimicrobial activity for enhancing the quality, safety and shelf life of foods. In the literature, it was found that cinnamon oil had high antimicrobial effect against some pathogenic microorganisms such as Campylobacter jejuni, Salmonella enteritidis, Escherichia coli, Staphylococcus aureus and Listeria monocytogenes. In this study, cinnamon oil NEs/MEs (10 wt% total oil phase) was designed with a low energy approach by the spontaneous emulsification method. Oil phase with different concentrations and combinations including emulsifier (Tween 80), cinnamon oil and carrier oil (coconut oil) was titrated into water phase (distillate water or phosphate buffer (pH: 7.0)) which was mixed continuously and NEs/MEs formation occurred via internal chemical energy of the system. For the physical characterization of the NEs/MEs, Dynamic Light Scattering (DLS) and Transmission Electron Microscopy (TEM) techniques were used. Both DLS and TEM methods gave parallel results and particle size of the NEs/MEs and found in the range of 5-100 nm. In order to determine the antimicrobial activity, agar disc diffusion method was applied and E.coli was used as the model microorganism. It was seen that NEs/MEs which were prepared by using cinnamon oil had high antimicrobial effect against E.coli. Moreover, when NEs/MEs activity compared with solutions’ at same concentrations, it was observed that NEs/MEs had 30%-60% higher antimicrobial activity. Results showed that oil phase composition had a major effect on initial droplet diameter and stable NEs/MEs with higher antimicrobial activity could be designed by using active compounds at lower concentrations that could have potential to be used in foods.

Plant protein-based food packaging films; recent advances in fabrication, characterization, and applications Hadidi, Milad; Jafarzadeh, Shima; FOROUGH, MEHRDAD; Garavand, Farhad; Alizadeh, Saeid; Salehabadi, Ali; Khaneghah, Amin Mousavi; Jafari, Seid Mahdi (2022-02-01) Background: Plant-based proteins as an alternative to synthetic polymers have attracted the interest of the global packaging industry in the last decade due to their biodegradability, sustainability, environmental, and beneficial health claims. Scope and approach: This review covers the recent developments in biodegradable packaging such as edible films/coatings and innovative packaging materials based on plant protein sources. The importance, sources, and techno-functional properties of plant-derived prote...
Spatial distribution of organic pollutants in Bursa atmosphere : seasonality and health effects Yılmaz Civan, Mihriban; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2010) The assessment of volatile organic compounds (VOCs) has become an area of particular interest in the field of atmospheric pollution due to their adverse health and environmental effects. This study is aimed to identify, quantify and characterize VOC in different urban areas and industrial areas in Bursa. The spatial distribution, seasonal variation as well as health risks assessment of VOC were discussed. Air samples were collected by means of sorbent passive sampling at over 50 sampling points in Bursa and...
Pollution characteristics and human health risks of potentially (eco) toxic elements (PTEs) in road dust from metropolitan area of Hefei, China Ali, Muhammad Ubaid; Liu, Guijian; Yousaf, Balal; Abbas, Qumber; Ullah, Habib; Munir, Mehr Ahmed Mujtaba; Fu, Biao (2017-08-01) This study aims to investigate the pollution characteristics of road dust and their associated health risks of potentially toxic elements (PTEs) to humans using array-based risk assessment models described by United States Environmental Protection Agency (USEPA) in a metropolitan area of Hefei, China. Geoaccumulation index (I-geo) was used to describe pollution characteristics of roadside dust in urban, periurban and industrial areas. Results indicate that industrial roadside dust was contaminated with Fe, ...
PREPARATION OF POLYMER MULTILAYER FILMS FOR FOOD TECHNOLOGY APPLICATIONS Tidim, Gökçe; Erel Göktepe, İrem; Soyer, Yeşim; Department of Chemistry (2023-1-20) In recent years, there has been intense research going on to develop new packaging technologies to improve the safety and quality of the food. Natural polymers not only reduce the consumer health risks but also provide less processed and more environment friendly food packages. Alginate and chitosan are suitable polymers for food technology due to their biocompatibility, biodegradability, and non-toxicity. In addition to the antibacterial properties of chitosan, pH responsive behaviour of alginate and chit...
Ambient VOC concentrations in the city of Balikesir and its environment Yalçın, Giyasettin Efdal; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2013) The assessment of volatile organic compounds (VOCs) has become an important field of interest in atmospheric pollution. This study quantifies and characterizes the ambient levels and spatial distribution of VOCs in urban and rural areas of Balıkesir. In addition, for the city drinking water dam excess flux from the traffic estimation was done. For these assessments passive sampling of VOCs performed at approximately 50 locations in and around the city of Balıkesir and analyzed with GC-FID system. Tenax TA w...
