Detection of residues of the epoxy adhesive component bisphenol A diglycidyl ether (BADGE) in microwave susceptors and its migration into food

Food Additives and Contaminants

Abstract

Susceptors are an example of one of the many new products being introduced into food packaging. They are used to achieve local areas of high temperature; this has the effect of browning the food during microwave cooking. Previous work by Begley et al. had suggested that one particular cold cure adhesive component, bisphenol A diglycidyl ether (BADGE), might be present in some susceptor products but gave little indication as to the retail use of these products. As a result an investigation of UK retail samples was carried out in January 1992. Most of the susceptors tested contained no detectable BADGE ( < 0.1 mg/kg), however, two brands of pizza were found to be packaged with susceptors containing BADGE at between 700 and 800 mg/kg (1.8-2.0 mg/dm2). Migration of BADGE into the pizzas in question was 0.1-0.7 mg/kg when they were cooked in their packaging according to on-pack instructions. Further tests undertaken in June 1992 confirmed earlier findings when from a total of 54 samples purchased covering seven manufacturers, nine samples of susceptors used in one brand contained BADGE at concentrations between 1900 and 3200 mg/kg. The manufacturer of this brand has stopped supplying further products to the retail market using this ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
