Food contaminants monitoring is conducted in an intensive manner yet, there are still food safety scandals related to various chemical compounds. This fact highlights the need review requirements posed by current legal framework on analytical methods performance and evaluate its application published studies. Herein, we present inventory including more than 470 publications screening confirmatory methods, which were used control hazardous compounds such as pesticides, antibiotics,...
Microplastic research has not reached a consensus on how to analyse control data.• We tested 51 correction methods find if currently used are valid.• Only 7 of the were found suitable for analysis microplastic data.
Bacterial pathogens represent a safety concern in the food industry, and this is amplified by lack of sensing devices that can be applied on-site non-trained personnel. In study, peroxidase-mimicking activity gold nanostars was exploited to develop user-friendly colourimetric sensor. A smartphone as an image reader analyser, empowered with novel App developed in-house. The mobile evaluated compared commercial for its capability quantify generated signals. major obstacle found sensors relying...
Agricultural systems are increasingly impacted by micro- and nanoplastic (MNP) pollution raising concerns for food safety security. To understand the scale of problem develop mitigation strategies, there is a need to characterise effects impacts MNP. Here, we discuss main MNP entry pathways into human chain their effects/impact on feed sources, identifying major research gaps hindering robust risk assessments pollution. We identified emerging current analytical methods facilitate closing...
Per- and polyfluoroalkyl substances (PFAS) are environmentally persistent pervasive. Understanding the toxicity of PFAS to wildlife is difficult, both due complexity biotic abiotic perturbations in taxa under study practical ethical problems associated with studying impacts environmental pollutants on free living wildlife. One avenue inquiry into effects pollutants, such as PFAS, assessing impact host gut microbiome. Here we show microbial composition biochemical functional outputs from...
Per- and poly-fluoroalkyl substances (PFAS) pose a threat to organisms ecosystems due their persistent nature. Ecotoxicology endpoints used in regulatory guidelines may not reflect multiple, low-level but stressors. This study examines the biological effects of PFAS on Eastern short-necked turtles Queensland, Australia. In this study, blood samples were collected analysed for PFAS, hormone levels, functional omics endpoints. High levels found at impacted site, with PFOS being dominant...
Abstract Upon entering the environment, surface properties of pristine plastics are rapidly altered due to interactions with exogenous biomolecules, contaminants, and even microbiota, which ultimately alter their ecological impacts. When present in biological fluids or high protein environments, micro(nano)plastics bind proteins, form a corona around particle. Although significant body literature exists on formation nanomaterials, less is known about how physiochemical microplastics may...
Bottom-up, end-user based feed, and food analysis through smartphone quantification of lateral flow assays (LFA) has the potential to cause a paradigm shift in testing capabilities. However, most developed devices do not test presence implications inter-phone variation. Much discussion remains regarding optimum color space for colorimetric analyses and, an in-depth comparison performance is missing. Moreover, light-shielding box often used avoid variations caused by background illumination...
Quantification of colorimetric assays with smartphones is being increasingly reported. However, a complete characterization the performance existing color spaces and single-color channels for optimum color/intensity change quantification absent. Moreover, it has not been ascertained if necessary to utilize reach optimal assay quantification. In this study, randomized channel approach was adapted utilizing all single from RGB, HSV, CieLab space nonrepeating random combinations two three these...
Gold nanostars (GNST), gold nanospheres (GNP) and carbon black (CB) are chosen as alternative nanomaterials to modify screen-printed electrodes (c-SPEs). The resulting three kinds of modified c-SPEs (GNP-SPE, CB-SPE GNSP-SPE) were electrochemically microscopically characterized compared with standardized after pretreatment phosphate buffer by pre-anodization (pre-SPE). results show outstanding electrochemical performance the black-modified SPEs which low transient current, capacitance good...
Accidental milk cross-contamination is one of the most common causes for costly food recalls. Yet, quantifying trace-levels allergen time-consuming and current methods are not adapted routine analyses making quality control trace-level content impractical. This perpetuates voluntary "may-contain" statements that unhelpful people suffering from allergies. Here, we developed a rapid LC-MS method enabling quantification by comparing all tryptic-peptides major allergens. The bovine-specific αS-2...
The trend of the number publications on a research field is often used to quantify interest and effort, but this measure biased by general publication record inflation. This study introduces novel metric as an unbiased quantitative tool for analysis bibliometrics. was reanalyze reported trends perform in-depth analyses patent groups broad range in life-sciences. confirmed that inflation bias frequently results incorrect identification field-specific increased growth. It shown enables more...
The current food safety testing system, based on laboratory-based quantification, is difficult to scale up in line with the growth export market and does not enable traceability through nodes of supply system. Screening assays, for example, lateral flow assays (LFAs), can improve but often lack required reliability guarantee compliance. Here, we present an alternative pipeline secure on-site compliance testing, using allergens as a case study. features smartphone-driven LFA quantification...
The popularity of insect protein as a food and feed supplement is growing. Protein quality, end use prices vary considerably between different species, which may incentivise adulteration. Here, near-infrared (NIR) spectroscopy chemometrics were used to detect the presence cricket, black soldier fly larvae (BSFL) mealworm proteins in simulated complex mixture. Additionally, BSFL powders collected from three commercial sources investigated determine whether NIR-based technology can...
Color analysis has been essential for the interpretation of optical readouts, e.g. colorimetry, fluorescence, spectroscopy, and scanometry. However, existing colorimetric readers can hardly eliminate color interference colored solutions, e.g., interpreting pH test strips to assess value red wine. This paper introduces a smartphone modulated reader that is compatible with most models novel subtraction algorithm eliminates interferences due solutions. Experiments were conducted validate...
