Two decades of research in dietary acrylamide: What do we know today

Estimation of dietary acrylamide exposure of Ethiopian population through coffee consumption

This study estimated the acrylamide exposure of the Ethiopian population through traditional brewing of Coffee arabica. Acrylamide concentrations in traditionally processed Ethiopian C. arabica varieties from Jimma, Sidama, Yirgacheffe, Nekemte, and Hararge were measured. A qualitative survey in Addis Ababa was used to develop a traditional coffee brewing flowchart, which was then applied in a laboratory setting. Acrylamide concentrations in roasted coffee powders were found to be 944.01, 861.67, 739.63, 726.35, and 326.60 μg/kg for Hararge, Nekemte, Jimma, Yirgacheffe, and Sidama, respectively. First brew concentrations were 119.97, 112.10, 108.68, 94.07, and 6.67 μg/L, and second brew concentrations were 21.41, 16.45, 16.77, 3.92, and 6.31 μg/L for the respective varieties of Nekemte, Yirgachefe, Jimma, Hararge, and Sidama. Estimated daily intakes (EDI) of acrylamide, based on coffee consumption data, were well below harmful levels (< 200 μg/kg bw/day), with Target Hazard Quotient (THQ) values indicating minimal non-carcinogenic risk (< 1). The study also found low concern for non-neoplastic effects (intake < 0.2 μg/kg bw/day) from Sidama and Nekemte coffees, although a relatively higher concern was observed for Nekemte in specific areas. The findings suggest that reducing acrylamide content in coffee through preventive actions and mitigation strategies is advisable to minimize potential health risks.

Acrylamide, hydroxymethylfurfural and furfural in ready-to-eat foods consumed by child population: Presence, risk assessment and future perspectives

Food intake contributes to adequate growth and neurodevelopment of children. Ready-to-eat foods, frequently consumed by this population, are sources of acrylamide (AA), hydroxymethylfurfural (HMF) and furfural (FF). In this sense, a review of the AA, HMF, and FF presence in ready-to-eat foods was evaluated through a systematic search to infer the risk of exposure in the child population. About 75.8%, 24.2%, and 21% of the studies found AA, HMF, and FF in ready-to-eat foods, respectively. AA is predominant in processed and ultra-processed foods, while HMF and FF are commonly found in fruit-based foods. Only 17.7% of the studies assessed the children's risk of exposure, based on the contaminant concentration in ready-to-eat food and not after gastrointestinal digestion, a more realistic measure. Therefore, with the obtained information and found gaps, it is expected that new strategies will be proposed to assess the vulnerability of the child population to these processing contaminants.

The impact of natural spices additions on hazards development and quality control in roast beef patties

The current focus in thermally processed meat production is to reduce the presence of hazardous compounds while maintaining product quality. This study utilized UPLC-MS/MS to examine the effects of rosemary, turmeric, and bay leaf on the development of hazards in roast beef patties, which demonstrated simultaneous inhibitory effects on malondialdehyde, glyoxal, methylglyoxal, 12 heterocyclic aromatic amines, acrylamide, and 5-hydroxymethylfurfural. Correlation analysis revealed that the total phenolic content and ferric-reducing antioxidant power of the spices were negatively correlated with polar hazards, non-polar heterocyclic aromatic amines, and aldehyde hazards, respectively. These findings underscore the vital role of hydroxyl groups and aromatic rings of phenols in inhibiting hazards formation. Additionally, the application of spices significantly reduced cooking loss and water loss and positively influenced textural quality and amino acid retention. These findings contribute to the understanding of the inhibitory effects of spices on multiple hazards and the quality control of heat-processed meat products.

Mechanism of action of anthocyanin on the detoxification of foodborne contaminants-A review of recent literature

Foodborne contaminants refer to substances that are present in food and threaten food safety. Due to the progress in detection technology and the rising concerns regarding public health, there has been a surge in research focusing on the dangers posed by foodborne contaminants. These studies aim to explore and implement strategies that are both safe and efficient in mitigating the associated risks. Anthocyanins, a class of flavonoids, are abundantly present in various plant species, such as blueberries, grapes, purple sweet potatoes, cherries, mulberries, and others. Numerous epidemiological and nutritional intervention studies have provided evidence indicating that the consumption of anthocyanins through dietary intake offers a range of protective effects against the detrimental impact of foodborne contaminants. The present study aims to differentiate between two distinct subclasses of foodborne contaminants: those that are generated during the processing of food and those that originate from the surrounding environment. Furthermore, the impact of anthocyanins on foodborne contaminants was also summarized based on a review of articles published within the last 10 years. However, further investigation is warranted regarding the mechanism by which anthocyanins target foodborne contaminants, as well as the potential impact of individual variations in response. Additionally, it is important to note that there is currently a dearth of clinical research examining the efficacy of anthocyanins as an intervention for mitigating the effects of foodborne pollutants. Thus, by exploring the detoxification effect and mechanism of anthocyanins on foodborne pollutants, this review thereby provides evidence, supporting the utilization of anthocyanin-rich diets as a means to mitigate the detrimental effects of foodborne contaminants.

New and Rapid Analytical Method Using HPLC-MS Detection for Acrylamide Determination in Black Ripe Olives

The presence of acrylamide, a known human carcinogen, in various heated foods raises significant concerns among consumers. Therefore, the development of a good analytical method is of paramount interest to the scientific community. Keeping this in view, a rapid, simple, reliable, and low-cost analytical method was developed and validated for acrylamide quantification in black ripe olives. The method consisted of the water extraction of the compounds from crushed olives with the addition of (13C3)acrylamide as an internal standard. The quantification was performed using high-pressure liquid chromatography and mass detection with positive electrospray ionization. The limits of detection and quantification were determined to be 4 and 11 µg/kg, respectively. The developed method exhibited excellent results in terms of accuracy (98.4-104.8%) and intra- and inter-day precision limits, both less than 20%. This new method was carried out by analyzing 15 samples of Spanish commercial black ripe olives, revealing a wide range of values, from 79 to 1068 µg/kg of fruit. The new protocol reduces the analysis time to just one hour per sample versus the minimum 24 h required by gas chromatography and mass detection, meaning that it could be a good option for the routine analysis of acrylamide in black ripe olives, and may be extendable to the analysis of this compound in other foods.

Asparaginase Treatment of Sea Buckthorn Berries as an Effective Tool for Acrylamide Reduction in Nutritionally Enriched Wholegrain Wheat, Rye and Triticale Biscuits

Sea buckthorn pomace is a by-product of juice production, which is still rich in bioactive compounds. After drying, the pomace can be effectively used as a valuable addition to bakery products supporting their nutritional value. However, due to the high content of the amino acid asparagine in sea buckthorn, this promising material contributes to the undesirable formation of acrylamide. To reduce the risk from this potentially carcinogenic compound, enzymatic treatment of sea buckthorn with asparaginase was applied, which resulted in a substantial reduction of asparagine content from 1834 mg/kg in untreated dried sea buckthorn pomace to 89 mg/kg in enzymatically treated dried sea buckthorn pomace. 10% substitution of wholegrain cereal flour with enzymatically treated sea buckthorn pomace powder in rye and triticale biscuits resulted in a 35% reduction in acrylamide content, in the case of wholegrain wheat biscuits up to a 64% reduction, compared to biscuits with untreated sea buckthorn pomace powder. This study confirmed that treating fruit with asparaginase is an effective way to reduce health risk caused by acrylamide in biscuits enriched with nutritionally valuable fruit pomace.

Occurrence and Dietary Exposure to Acrylamide from Foods Consumed within and outside Main Meals in Singapore

This study investigated the influence of 'snackification' in Singaporean diets, leading to increased dietary acrylamide exposure. Acrylamide concentrations in commonly consumed foods within and outside the main meals were measured using liquid chromatography with tandem mass spectrometry (LC-MS/MS). High acrylamide concentrations were detected in vegetables cooked at high temperatures (ranging from 0.5 to 478.4 µg/kg) and potato-based crackers and chips (ranging from 81.8 to 2095.8 µg/kg). The estimated total dietary exposure for the Singapore population was 0.165 µg/kg bw/day for general consumers and 0.392 µg/kg bw/day for high consumers (95th percentile). The acrylamide exposure from outside main meals was nearly equivalent to that from within the main meals. The calculated margins of exposure (MOE) were below 10,000, indicating potential human health concern. These findings highlight the need for industry practices and consumer advisories to reduce acrylamide exposure from foods consumed both within and outside main meals.
