Food contact materials (FCM) made from PVC, such as e.g. gaskets of metal lids or cling films, may release plasticizers into the packed food. Such migration repeatedly exceeded legal limits or non-authorized plasticizers have been used. In a European enforcement campaign on migration from gaskets into oily foods in 2011, for example legal limits were exceeded in 24% of the 308 samples analyzed . The EU also banned the use of certain phthalates as plasticizers for toys and childcare products, whereas its content is limited to below 0.1 % . Furthermore the directive 2011/65/EU will restrict “certain hazardous substances in electrical and electronic equipment”, including the same group of phthalates . Plasticizers are analyzed and quantified by GC-FID or MS if detection limits lower than 0.1 % are required. So far up to 40 different plasticizers were found and quantified in FCM and toys.
The poster outlines a comprehensive, fully automated analysis of plasticizers in toys and food stuff.
From Farm to Landfill: Results of a Campus-Community Awareness Event to Promote Sustainable Food SystemsPoster
In April 2017, a campus-community event (N=42 participants) was held to promote sustainable food systems by educating participants about concepts ranging from food production to nutrition and food waste management. This poster discusses the resulting increased awareness and knowledge of a our local food system among participants, which can be fostered through educational events that combine opportunities for research, teaching, and practice.READ MORE
Comparing The Anti-Alzheimer's Activity of Different Types of CoffeePoster
This study found that coffee solutions treated at 5% are toxic to neurons. However, the toxicity reduced significantly at 2.5%. While the toxicity was significantly less allowing for more cells to survive at 2.5%, the levels of toxic amyloid beta 1-42 significantly reduced. This reduction in amyloid beta is associated with improvement in cognitive performance, as the presence of these toxic peptides is one of the characteristics of AD pathophysiology.READ MORE
C1 Complement mediates human cord blood serum derived APP α-secretase cleavage activity in vitroPoster
Our results indicate that CBS contains proteins that promote α-secretase like enzymatic activity. LC-MS/MS analysis in CBSF and AgBSF revealed the presence of 142 proteins of which C1 subunits and alpha-2-macroglobulin showed significantly greater levels in αCBSF compared with αAgBSF. further study showed,C1 subunits can enhance sAPPα production and Aβ reduction in cell culture conditionREAD MORE
