“…2c). Extraction and determination of the constituents in a fatty matrix are complex, and the extraction protocol must be appropriate for isolating the compounds of interest to avoid interference by other compounds, besides lipids, present in the matrix (Yu et al 2017(Yu et al , 2019. When SPME/GC-MS is utilized for the determination of volatile compounds, the interferences can be minimized using an appropriate GC-MS program.…”

This study compared the antioxidant properties of oregano essential oil (OEO) and butylated hydroxytoluene (BHT) alone and when combined. The principal components in OEO were gamma terpinene (25.1 g/100 g), terpinen-4-ol (16.7 g/100 g), and carvacrol (16.2 g/100 g). OEO showed 60% DPPH inhibition and 10 mg/g total phenolic compounds. The antioxidant capacity of OEO (0.02, 0.10, and 0.20 g/100 g) and BHT (0.01 and 0.02 g/ 100 g) and their combinations were tested in sunflower oil oven-heated at 60°C, by measuring the chemical (peroxide value, p-anisidine value, and conjugated dienes) and volatile (hexanal, 2-heptanal, and 2,4-decadienal) indicators over 14 days. The combined samples (oregano essential oil and BHT) showed the greatest protection against lipid oxidation. On day 14, the peroxide value of the control (without added antioxidants), OEO (0.02 g/100 g), BHT (0.01 g/100 g), and OEO ? BHT (0.02 ? 0.01 g/ 100 g) treatments decreased in the order of 136.36, 102.68, 83.24, and 41.37 meqO2/kg, respectively, for example. In the consumer sensory test, samples containing OEO at 0.02 and 0.10 g/100 g attained greater acceptance scores (7.3 and 6.7, respectively, on a 9-point hedonic scale) as compared with the control (6.1). Discriminative duo-trio testing presented significant differences between all OEOcontaining samples relative to the control. The synergistic antioxidant activity between OEO (termination-enhancing antioxidant) and BHT (chain-breaking antioxidant) demonstrates an alternative approach to impede lipid oxidation in foods, by decreasing the use of synthetic compounds in the food industry.

“…The purification is the key step in the detection of the level of AFB 1 ; traditional methods of AFB 1 mainly include liquid-liquid extraction (LEE), dispersive liquid-liquid microextraction, solid-phase extraction (SPE), molecularly imprinted polymer, immunoaffinity column, etc. ; most of these are time-consuming and expensive [14]. Encouragingly, Xie J et al [6] provide the first report of a broadspectrum specific mAb-modified reduced graphene nanosheets (rGO) film that can be designed to extract and purify AFB 1 , AFB 2 , AFG 1 , AFG 2 , AFM 1 , and AFM 2 in rabbit serum.…”

“…However, in the process of extracting AFB 1 , the complexity of food components, especially fat, causes some interference to AFB 1 . In addition, AFB 1 is lipophilic; it is difficult to extract AFB 1 from soybean and vegetable oil [14,15]. The purification is not strong enough, the AFB 1 in vegetable oil cannot be completely removed, and lower lever of AFB 1 will also lead to human liver damage [1,16].…”

Aflatoxin B1 Occurrence, Detection and Toxicological Effects

View full text Add to dashboard Cite

Aflatoxin B 1 (AFB 1 ) is harmful to human health, mainly resulting from its toxic effects on the liver. AFB 1 can lead to liver cell necrosis, hemorrhage, fibrosis, cirrhosis, etc. Acute AFB 1 exposure at high levels can lead to hepatitis, whereas chronic exposure can result in liver cancer. In the past decades, a series of methods and techniques for detecting AFB 1 , including enzyme-linked immunosorbent assay (ELISA), high-performance liquid chromatography (HPLC), and thin-layer chromatography (TLC), have been developed. This study reviewed the detection methods of AFB 1 and the corresponding utilization and summarizes all methods for evaluating the toxification of AFB 1 .

“…Conversely, the AFT-albumin adduct with a longer half-life of www.bosaljournals/chemint/ editorci@bosaljournals.com 30-60 days, relative stability and minimum variability can be estimated in peripheral blood to measure the long-term AFT exposure (Williams et al, 2004). Results revealed that various factors are responsible for AFTs production and all living organisms are vulnerable for its toxic effects (Asare Bediako et al, 2019;Blankson et al, 2019;Cheng et al, 2019;Dí az Nieto et al, 2019;Frisvad et al, 2019;Gummadidala et al, 2019;Hamza et al, 2019;Magzoub et al, 2019;Mwakinyali et al, 2019;Shahbazi and Shavisi, 2019;Singh and Cotty, 2019;Tsounidi et al, 2019;Wang et al, 2019a;Wang et al, 2019b;Wu et al, 2019;Xie et al, 2019a;Xie et al, 2019b;Yu et al, 2019;Zeng et al, 2019;Zhao et al, 2019;Zhou et al, 2019). So far, there is need to develop the detoxification methods to save food and feed items without harming the nutritional and sensory characteristics.…”

Aflatoxins (AFTs) are toxic products of fungal metabolism, associated with serious health consequences and substantial economic losses to agriculture, livestock and poultry sectors, particularly in the developing countries. This review outlines the current information on AFTs in terms of historical background, classification, relative occurrence and co-existence with other mycotoxins in various food commodities. The phenomenon of aflatoxin (AFT) biosynthesis has been elucidated with reference to molecular basis, genetic regulation and factors affecting the AFT production. Moreover, the in vivo disposition kinetics, toxicological action and toxico-pathological consequences of AFTs have also been highlighted. Currently employed strategies for the detection and detoxification of AFTs, biomarkers of exposure assessment, potential economic impact and regulatory considerations regarding the AFTs have been emphasized.
