Decentralized food safety and authentication on cellulose paper‐based analytical platform: A review

Comprehensive Reviews in Food Science and Food Safety, Год журнала: 2024, Номер 23(5)

Опубликована: Авг. 13, 2024

Abstract Food safety and authenticity analysis play a pivotal role in guaranteeing food quality, safeguarding public health, upholding consumer trust. In recent years, significant social progress has presented fresh challenges the realm of analysis, underscoring imperative requirement to devise innovative expedient approaches for conducting on‐site assessments. Consequently, cellulose paper‐based devices (PADs) have come into spotlight due their characteristics microchannels inherent capillary action. This review summarizes advances PADs various products, comprising fabrication strategies, detection methods such as mass spectrometry multi‐mode detection, sampling processing considerations, well applications screening factors assessing developed past 3 years. According above studies, face limited sample processing, inadequate multiplexing capabilities, workflow integration, while emerging innovations, use simplified pretreatment techniques, integration advanced nanomaterials, instruments portable spectrometer innovation multimodal methods, offer potential solutions are highlighted promising directions. underscores facilitating decentralized, cost‐effective, testing methodologies maintain standards. With progression interdisciplinary research, expected become essential platforms authentication thereby significantly enhancing global consumers.

Journal of The Electrochemical Society, Год журнала: 2024, Номер 171(9), С. 097505 - 097505

Опубликована: Сен. 2, 2024

Ochratoxine A is a very stable mycotoxin which cannot be destroyed below 250°C. Found in grains, coffee, grapes, wine, milk, and meat, it can produce kidney damage cancer. Therefore, smartphone operated intellingent stochastic miniplatform was designed, characterised, validated for the on-site screening of milk fast determination ochratoxine A. (Z)-N-[2-(4-hydroxyphenyl) ethyl]octadec-9-enamide used as modifier gold matrix screen printed sensor sensing tool design miniplatform. wide linear concentration range (1.0 × 10 −15 − 1.0 −7 mol l ‒1 ) low limit quantification 1 fmol were achieved assay ochratoxin Recovery values higher than 99.00% obtained A, when cow’s vegetarian milk.
