Article Synopsis
- Food contact paperboard, especially recycled ones, might contaminate food with chemicals, both added and unintentional.
- A study analyzed paperboard samples at different stages of recycling, finding that most harmful chemicals were reduced post-recycling, though some trace elements like chlorine remained.
- The study also noted that while the original paperboard had chemicals causing potential hormonal disruptions, these effects were significantly diminished in the recycled paperboard.
The endocrine activity and endocrine disruptor (ED) chemical profiles of eleven plastic packaging materials covering five major polymer types (3PET, 1HDPE, 4LDPE, 2 PP, and 1SAN) were investigated using in vitro cell-based reporter-gene assays and a non-targeted chemical analysis using gas chromatography coupled to mass spectrometry (GC-MS). To mimic cosmetic contact, six simulants (acidic, alkaline, neutral water, ethanol 30%, glycerin, and paraffin) were used in migration assays performed by filling the packaging with simulant. After 1 month at 50 °C, simulants were concentrated by Solid Phase Extraction (SPE) or Liquid-Liquid Extraction (LLE).

- TEHTM is a type of plasticizer used in medical devices instead of a harmful chemical called DEHP.
- Scientists studied how TEHTM breaks down in the body and how these breakdown products affect hormones like estrogen and testosterone.
- They found that only some of the breakdown products have effects on hormones, but the levels in human urine suggest these won't cause problems in real life.
Plasticizers added to polyvinylchloride (PVC) used in medical devices can be released into patients' biological fluids. Di-(2-ethylhexyl)phthalate (DEHP), a well-known reprotoxic and endocrine disruptor, must be replaced by alternative compounds. Di-(2-ethylhexyl) terephthalate (DEHT) is an interesting candidate due to its lower migration from PVC and its lack of reprotoxicity.

Since the processing and formulation of food influence iron bioavailability, the present study investigated for the first time, their effects on hummus. Firstly, iron bioaccessibility was assessed on eight samples (prepared according to the screening Hadamard matrix) by in vitro digestion preceding iron dialysis.
