AI Article Synopsis
- Patulin is a toxic compound mainly found in moldy apples, making its monitoring essential for food safety, especially for vulnerable groups like the elderly and children.
- A new polymeric adsorbent has been developed for efficiently extracting patulin from apple juice, enabling accurate detection through chromatography.
- This cost-effective polymer, which binds strongly to patulin due to its unique design, can be mass-produced and serves as a model for creating adsorbents for other toxins in various food products.
Article Abstract
Patulin is a toxic compound which is found predominantly in apples affected by mould rot. Since apples and apple-containing products are a popular food for the elderly, children and babies, the monitoring of the toxin is crucial. This paper describes a development of a computationally-designed polymeric adsorbent for the solid-phase extraction of patulin, which provides an effective clean-up of the food samples and allows the detection and accurate quantification of patulin levels present in apple juice using conventional chromatography methods. The developed bespoke polymer demonstrates a quantitative binding towards the patulin present in undiluted apple juice. The polymer is inexpensive and easy to mass-produce. The contributing factors to the function of the adsorbent is a combination of acidic and basic functional monomers producing a zwitterionic complex in the solution that formed stronger binding complexes with the patulin molecule. The protocols described in this paper provide a blueprint for the development of polymeric adsorbents for other toxins or different food matrices.
