1. Trace analysis of environmental endocrine disrupting contaminant bisphenol A in canned, glass and polyethylene terephthalate plastic carbonated beverages of diverse flavors and origin
Abstract Bisphenol A (BPA) is a hazardous contaminant demonstrating endocrine disrupting properties, and assumed to be involved in the pathogenesis of various cancer diseases for instance prostate, lung and breast cancer. The objective of the present study was to estimate the BPA amounts in carbonated beverages from the Saudi Arabian market for the first tim

2. Conservation of crisp lettuce in different post-harvest storage conditions
ABSTRACT The objective of this work was to evaluate the post-harvest quality and the final storage time of the hydroponic crisp lettuce ‘Brida’, conditioned in different types of plastic packaging and environments. The statistical design was a completely randomized 3x2 factorial design, with 3 types of packages (control (without plastic packaging), perf

6. Evaluation of metals in tomato sauces stored in different types of packaging
Abstract There is a growing concern about health and food safety when it comes to processed food. In the present study, it has been hypothesized that tomato sauces contain high amounts of metals possibly leached from packaging. Concentrations of As, Cd, Pb, Cr, Ni, Sn and Sb were determined by ICP-MS in tomato sauces stored in metallic, plastic, cellulosic

8. Microstructure and thermal and functional properties of biodegradable films produced using zein
Abstract Research is being conducted in an attempt to produce biodegradable packaging to replace plastic products, thereby reducing solid waste disposal. In this work, zein films were produced from vegetable oils (macadamia, olive and buriti) and from pure oleic acid. The surface of zein-based films made using oleic acid has a good lipid distribution. The h

9. Influence of temperature and packaging type on quality parameters and antimicrobial properties during Yateí honey storage
Abstract Tetragonisca fiebrigi, is a bee of the subfamily Meliponidae traditionally known as Yateí. Its honey differs from the honey produced by Apis mellifera because it is less viscous, more acidic, has sweetness and particular aromas. It is important to know the behavior of yatei honey in different storage conditions, in order to preserve the characteris

10. Effect of the Addition of Carnauba Wax on Physicochemical Properties of Chitosan Films
Films and edible coatings of natural polymers have been proposed as an attractive alternative for conventional plastic packaging because of their excellent biodegradability and biocompatibility. However, natural polymers, like chitosan, are hydrophilic and present poor water barrier properties. The addition of wax or other hydrophobic substances decreases wa

11. ICP OES Determination of Contaminant Elements Leached from Food Packaging Films
ABSTRACT Determination of potential contaminants elements in food packing films arising from contact with acidic aqueous foods was undertaken by inductively coupled plasma optical emission spectrometry (ICP OES) in accordance with DIN EN 1186-1. Test sections from plastic films were totally immersed in 3% w/v CH3COOH used as the food simulant. Testing was c
