A review of hazards in meat products: Multiple pathways, hazards and mitigation of polycyclic aromatic hydrocarbons

Polycyclic aromatic hydrocarbons (PAHs) are stable carcinogens that are widely distributed in the environment and food, and humans are exposed to PAHs primarily through the respiratory tracts, dermal contact, and dietary intake. Meat products are an essential part of the human diet, and the formation of PAHs during meat processing is unavoidable. Therefore, a comprehensive understanding of PAHs in meat products can be a contribution to the minimization of human exposure dose. The aim of this review is to provide a comprehensive description of the toxicological analysis of PAHs intake and the various production pathways. The distribution of different PAHs in various meat products, including poultry and aquatic products, is analyzed. The discussion focuses on controlling PAHs through the use of endogenous marinades and antioxidants as well as reducing exogenous particulate matter-PAHs attachment. In addition, potential strategies for PAHs reduction and possible directions for future research are proposed.

Effect of air-frying on formation and correlations of polycyclic aromatic hydrocarbons, acrylamide, and heterocyclic aromatic amines in foods and risk assessment

The levels of acrylamide (AA), four polycyclic aromatic hydrocarbons (PAH4), and heterocyclic aromatic amines (HAAs) in 184 air-fried agricultural, fishery, and animal products were measured using GC-MS and UPLC-MS/MS. Among the tested samples, sea algae exhibited the highest levels of PAH4 and eight specific HAAs (HAA8), while root and tuber crops had the greatest amount of AA. Agricultural and fisheries products had higher levels of all three contaminants, while livestock products had an inverse correlation between PAH4 and HAA8. The margin of exposure in the Korean population is considered "unlikely a concern" for all samples for PAH4 and HAA8, however, that for AA in cereal, vegetable, and root and tuber crops is deemed "may be a concern", with a value < 10,000 in all age groups. These findings suggest a need to evaluate dietary AA exposure in certain food categories and further research to minimize AA formation during air frying.

Optimization of cold plasma combined treatment process and its effect on the quality of Asian sea bass (Lates calcarifer) during refrigerated storage

BACKGROUND

Cold plasma exhibits broad applicability in the realm of fish sterilization and preservation. The combination process of plasma-activated water and dielectric barrier discharge (PAW-DBD) was optimized, and its disinfection effects on bass fillets were studied.

RESULTS

The best conditions for disinfection of PAW-DBD were as follows. Bass fillets were soaked in PAW for 150 s, and then treated by DBD system at 160 kV for 180 s. The total viable count (TVC) reduced by 1.68 log CFU g-1 . On the 15th day of refrigerated storage, TVC of PAW-DBD group was 7.01 log CFU g-1 , while the PAW and DBD group exhibited a TVC of 7.02 and 7.01 log CFU g-1 on day 12; the TVC of the control group was 7.13 log CFU g-1 on day 6. The sensory score, water-holding capacity, and 2-thiobarbituric acid reactive substance values of the PAW-DBD group were significantly higher than those of PAW and DBD group (P < 0.05), whereas the TVC, Pseudomonas spp. count, and pH of the group were significantly lower (P < 0.05) during refrigerated storage.

CONCLUSION

PAW-DBD treatment can enhance the disinfection effect, maintain good quality, and extend the storage period of bass fillets. © 2023 Society of Chemical Industry.

Understanding the heterocyclic aromatic amines: An overview and recent findings

Heterocyclic aromatic amines (HAAs) constitute a group of highly toxic organic compounds strongly associated with the onset of various types of cancer. This paper aims to serve as a valuable resource for food scientists working towards a better understanding of these compounds including formation, minimizing strategies, analysis, and toxicity as well as addressing existing gaps in the literature. Despite extensive research conducted on these compounds since their discovery, several aspects remain inadequately understood, necessitating further investigation. These include their formation pathways, toxic mechanisms, effective mitigation strategies, and specific health effects on humans. Nonetheless, recent research has yielded promising results, contributing significantly to our understanding of HAAs by proposing new potential formation pathways and innovative strategies for their reduction.

Assessing the Formation of Polycyclic Aromatic Hydrocarbons in Grilled Beef Steak and Beef Patty with Different Charcoals by the Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) Method with Gas Chromatography-Mass Spectrometry

This study investigated the effects of different charcoals on the occurrence of 16 polycyclic aromatic hydrocarbons (PAHs) in grilled beef steaks and beef patties. Seven different charcoals were used as follows: from oak wood (C1), from orange wood (C2), from Valonia oak wood (C3), from Marabu wood (C4), extruded charcoal from beech wood (C5), from coconut shells (C6), and from hazelnut shells (C7). The grilling times for each charcoal type were 6 min for the beef patties and 7 min for the beef steaks, until the internal temperature reached at least 74°C. The total concentration of 16 PAHs (PAH16) in beef steaks grilled with C1 (35.75 μg/kg) and C7 (36.39 μg/kg) was higher than that of C3 (23.80 μg/kg) and C6 (24.48 μg/kg; p<0.05). The highest amounts of PAH16 (216.40 μg/kg) were determined in the beef patty samples grilled using C5 (p<0.05). The summation of benzo[a]anthracene, chrysene, benzo[b]fluoranthene and benzo[a]pyrene, referred to as PAH4, was not detected in any of the beef steaks, whereas it was determined in the beef patties grilled with C2 (7.72 μg/kg) and C5 (22.95 μg/kg; p<0.05). The PAH16 concentrations of the beef patty samples in each charcoal group were significantly higher compared to the beef steaks (p<0.05). To avoid the formation of high PAH levels, the use of extruded charcoal and hazelnut shell charcoal should therefore be avoided when charcoal grilling beef steaks and beef patties, and low-fat meat products should be preferred.

Effect of curcumin on the formation of polycyclic aromatic hydrocarbons in grilled chicken wings

Organic macromolecules form carcinogenic and toxic substances such as polycyclic aromatic hydrocarbons (PAHs) under high temperature baking. Thus, this study investigated the effects and inhibition pathways of different curcumin concentrations (0.01, 0.05, 0.25, 0.3 mg/g) on seven PAHs in grilled chicken wings. The results demonstrated that curcumin concentrations displayed positive effects in inhibiting the formation of PAHs (16%-72%), increasing the total phenolic content (397.5-1934.4 mg/g) and free radical scavenging activity, and reducing TBARS values (31.15%-47.76%) and fatty acid content. Additionally, PCA and Pearson correlation analyses indicated that lipid oxidation (r = 0.42) and unsaturated fatty acids (r = 0.55) could promote the production of PAHs, while DPPH, ABTS and TPC could counteract their facilitation of PAHs. In conclusion, the addition of appropriate amounts of curcumin before grilling is a feasible strategy to reduce fat oxidation levels and the number of free radicals for the purpose of limiting PAHs content.

Effect of beef patties fortification with black garlic on the polycyclic aromatic hydrocarbons (PAHs) content and toxic potency

Nine different black garlic samples aged at varying temperatures and durations were added to the patties at 0.5% and 1% ratios and compared with raw garlic in terms of polycyclic aromatic hydrocarbons (PAHs) formation. The results showed that black garlic caused a reduction in the patties' content of ∑PAH8 by 38.17% to 94.12% compared to raw garlic, with the highest reduction percent in the patties fortified with 1% black garlic aged at 70 °C for 45 days. Beef patties fortified with black garlic reduced human exposure to PAHs from beef patties (from 1.66E to 01 to 6.04E-02 ng-TEQ_BaP kg^-1 bw per day). The negligible cancer risk associated with exposure to PAHs through the consumption of beef patties was confirmed by very low ILCR (incremental lifetime cancer risk) values of 5.44E-14 and 4.75E-12. Finally, patty fortification with black garlic could be suggested as an effective way to reduce PAHs formation and exposure from patties.

From Industrial Food Waste to Bioactive Ingredients: A Review on the Sustainable Management and Transformation of Plant-Derived Food Waste

According to the United Nations, approximately one-third of the food produced for human consumption is wasted. The actual linear "Take-Make-Dispose" model is nowadays obsolete and uneconomical for societies and the environment, while circular thinking in production systems and its effective adoption offers new opportunities and benefits. Following the "Waste Framework Directive" (2008/98/CE), the European Green Deal, and the actual Circular Economy Action Plan, when prevention is not possible, recovering an unavoidable food waste as a by-product represents a most promising pathway. Using last year's by-products, which are rich in nutrients and bioactive compounds, such as dietary fiber, polyphenols, and peptides, offer a wake-up call to the nutraceutical and cosmetic industry to invest and develop value-added products generated from food waste ingredients.

Mutagens in commercial food processing and its microbial transformation

Mutagens are chemical molecules that have the ability to damage DNA. Mutagens can enter into our body upon consumption of improperly cooked or processed food products such as high temperature or prolonged cooking duration. Mutagens are found in the food products can be classified into N-nitroso derivatives, polycyclic aromatic hydrocarbons, and heterocyclic aromatic amines. Food products with high fat and protein content are more prone to mutagenic formation. Microorganisms were found to be a potent weapon in the fight against various mutagens through biotransformation. Therefore, searching for the microorganisms which have the ability to transform mutagens and the development of techniques for the identification as well as detection of mutagens in food products is much needed. In the future, methods for the identification and detection of these mutagens as well as the identification of new and more potent microorganisms which can transform mutagens into non-mutagens are much needed.

The Effects of Volatile Organic Compounds (VOCs) on the Formation of Heterocyclic Amines (HAs) in Meat Patties, under Different Smoking Temperatures and Durations

In this study, UPLC-MS/MS was used to study the effects of smoking duration and temperature on the formation of heterocyclic amines (HAs) in smoke-processed meat patties. Four kinds of free HAs—including F-7,8-DiMeIQx; F-MeAαC; F-Harman and F-Norharman—and six kinds of protein-bound HAs—including B-AαC; B-7,8-DiMeIQx; B-Glu-p-1; B-MeAαC; B-Harman and B-Norharman—were detected and quantified. Among the free HAs, we observed a 23-fold content increase (p < 0.05), from 0−4 h (at 0 h and 4 h they were 4.24 ng·g−1 and 98.33 ng·g−1, respectively), and the content of the free HAs decreased to 78.80 ng·g−1, at 5 h. At the same time, the free HAs content increased from 53.52 ng·g−1, at 50 °C, to 127.16 ng·g−1, at 60 °C, and then decreased continuously. The content of the free HAs was the highest at 60 °C. For the protein-bound HAs, their content was found to generally decrease with the increase in smoking duration and temperature. However, at 5 h, the content of protein-bound HAs slightly increased to 984.2 ng·g−1. Meanwhile, at 90 °C, it increased to 1643.53 ng·g−1. Additionally, a total of 16 volatile organic compounds (VOCs) were found in all of the meat samples, of which 10 VOCs (one acid, three aldehydes and seven phenols) were significantly related to the formation of free HAs. These findings showed that all the different types of HAs were produced under low-temperature processing, which provided scientific insights into the potential generation of HAs during meat smoking processes and could be used as a reference to minimize the risks of cancer related to the consumption of smoked meat products.

Effect of olive leaf extract marination on heterocyclic aromatic amine formation in pan-fried salmon

BACKGROUND

In this study, the reducing effects of varying levels of olive leaf extract (0%, 0.25%, 0.5%, 1% and 2%) on the formation of heterocyclic aromatic amines (HAAs) in pan-cooked salmon at 180 and 220 °C were examined.

RESULTS

All salmon samples were analyzed for ten HAAs: IQx, IQ, MeIQx, MeIQ, 4,8-DiMeIQx, 7,8-DiMeIQx, PhIP, AαC, MeAαC and Trp-P-2. The most abundant HAA was MeIQ (≤2.98 ng g^-1 ) followed by Trp-P-2 (≤2.40 ng g^-1 ), MeIQx (≤0.83 ng g^-1 ), IQ (≤0.41 ng g^-1 ), 7,8-DiMeIQx (≤0.29 ng g^-1 ), 4,8-DiMeIQx (≤0.16 ng g^-1 ) and IQx (≤0.06 ng g^-1 ). However, PhIP, AαC and MeAαC were undetectable in all samples. In the control samples, HAAs were found at levels ranging from not detected to 2.40 ng g^-1 . Total HAA content was between 0.81 and 4.03 ng g^-1 . The olive leaf extracts reduced the total HAA levels at all certain concentration levels at 180 °C and the reducing effects were found to be 32.78-77.69%.

CONCLUSION

The current study displayed that olive leaf extracts could be efficient when added in up to 1% concentration prior to cooking for reducing HAA formation without changing organoleptic characteristics of salmon. © 2021 Society of Chemical Industry.

Non-thermal Technologies for Food Processing

Food is subjected to various thermal treatments during processes to enhance its shelf-life. But these thermal treatments may result in deterioration of the nutritional and sensory qualities of food. With the change in the lifestyle of people around the globe, their food needs have changed as well. Today's consumer demand is for clean and safe food without compromising the nutritional and sensory qualities of food. This directed the attention of food professionals toward the development of non-thermal technologies that are green, safe, and environment-friendly. In non-thermal processing, food is processed at near room temperature, so there is no damage to food because heat-sensitive nutritious materials are intact in the food, contrary to thermal processing of food. These non-thermal technologies can be utilized for treating all kinds of food like fruits, vegetables, pulses, spices, meat, fish, etc. Non-thermal technologies have emerged largely in the last few decades in food sector.

Is Ultra-High Temperature Processed Milk Safe in Terms of Heterocyclic Aromatic Amines?

Herein, the presence of heterocyclic aromatic amines (HAAs) in 24 different commercial ultra-high temperature processed (UHT) milk types was investigated. The dry matter and pH values of the samples were also determined. The milk types showed significant differences (p < 0.01) regarding the dry matter, pH values, and individual HAAs and total HAAs. The milk sample dry matter and pH values were in the range of 8.56-13.92% and 6.66-6.91, respectively. The growing up milk samples had the highest dry matter and pH values. While no significant correlation between the total HAAs and dry matter was found, a negative correlation (p < 0.01) between the total HAAs and pH value was determined. Among the tested HAAs, five compounds, (IQx (up to 0.06 ng), IQ (up to 0.10 ng), MeIQx (up to 0.55 ng), MeIQ (up to 1.97 ng), and PhIP (up to 0.39 ng)) were quantified in the samples. The average total HAAs of the samples ranged from 0.13 to 0.67 ng; however, one milk sample (200 mL) contained between 10.10 and 53.35 ng total HAAs. Therefore, it was shown that protein fortification and lactose hydrolysis substantially increased the formation of HAAs in UHT milk.

Is oven bag really advantageous in terms of heterocyclic aromatic amines and bisphenol-A? Chicken meat perspective

Herein, the effects of oven bag use belong to different brands on heterocyclic aromatic amine (HAA) formation and bisphenol-A (BPA) migration in cooked chicken meats (breast and leg) were investigated. Samples were also analyzed in terms of some qualitative properties (fatty acid profile, water, fat, pH, TBARS, cooking loss). Both oven bag use and meat type had an effect on qualitative properties of the samples. Total HAA amount changed between 6.53 and 42.32 ng/g, and HAA content was higher in breast meat. Total BPA content in samples cooked with oven bag ranged between non-quantified to 63.78 ng/g. Oven bag use reduced the total HAA amount at the rate of 12 - 68.82%, while it caused the BPA migration depends on the brand. However, it can be noted that the HAA and BPA levels were not at a level to pose a risk to human health in any of the samples.

Simultaneous Determination of Acrylamide, 5-Hydroxymethylfurfural, and Heterocyclic Aromatic Amines in Thermally Processed Foods by Ultrahigh-Performance Liquid Chromatography Coupled with a Q Exactive HF-X Mass Spectrometer

In this study, a rapid and reliable method based on ultrahigh-performance liquid chromatography coupled with Q Exactive HF-X mass spectrometry (UHPLC-QE/MS) was established for the simultaneous quantification and validation of acrylamide, 5-hydroxymethylfurfural, and 14 heterocyclic aromatic amines in thermally processed foods. With the optimization of the pretreatment method, all 16 hazardous compounds with different polarities were simultaneously extracted and purified by one-step purification. By studying various acquisition modes in detail, full MS + PRM detection using an electrospray ionization source in the positive mode gives an excellent-shaped chromatographic peak and thereby achieves a better quantitative ability for analytes in the matrix. This method demonstrated good quantification recovery in the range of 68.85-146.42%. The limits of quantification were within the range from 0.1 to 50 ng/mL. With the method proposed, the simultaneous determination of 16 hazardous compounds in different thermally processed foods was successfully applied. The all-fragment-ion approaches at high resolution have the ability to reduce false-positive peak detections arising from peak alignment software in the detection of samples significantly. The proposed isotope dilution UHPLC-QE/MS method was validated and demonstrated to be sensitive, accurate, and precise for the simultaneous quantification of multiple contaminants in one injection.
