Arsenic (As) compounds can be classified as organic or inorganic, with inorganic arsenic (iAs) having significantly higher toxicity than organic As. As may accumulate in food materials that have been exposed to As-contaminated environments. Thus, the “Sanitation Standard for Contaminants and Toxins in Foods” published by the Ministry of Health and Welfare set the standard limits for iAs content in rice, seaweed, seafood, and marine oils to safeguard public health. Therefore, a robust analytical method must be developed to selectively and quantitatively determine iAs content in rice, seaweed, seafood, and marine oils. Herein, we reported and verified the method of …

Effect Of Sterilization Conditions On The Formation Of Furan And Its Derivatives In Canned Foods With Different Substrates, Wen-Xuan Tsao, Bing-Huei Chen, Tsai-Hua Kao
Journal of Food and Drug Analysis
This study explored the effects of sterilization conditions on the formation of furan and its 10 derivatives in canned foods with a sterilizing value (F0) at 4. The contents of furans were determined by SPME arrow-GC-MS/MS, along with the furan precursors analyzed for elucidating the possible mechanism of furan formation. Results revealed that the total furan contents rose substantially in canned meat paste, tomato mackerel, chicken puree, tomato paste, pineapple slice, pineapple juice and carrot juice following sterilization. However, the total furan content did not change significantly ( p > 0.05) in canned oily mackerel, but decreased significantly ( p < 0.05) in canned apple puree after sterilization. With the exception of apple puree and pineapple slice, all the other canned foods showed a higher total furan content under low-temperature-long-time condition than that under high-temperature-short-time condition. Following heating, only the furan level showed a large increase in chicken puree, meat paste and tomato mackerel, whereas in canned fruit- and vegetable-based foods, the contents of furan and furfural showed a pronounced increase. The levels of alkylated furans were higher in sterilized samples containing high level of amino acid, while that of oxygenated furans were higher in sterilized samples containing high level of reducing sugar.

Journal of Food and Drug Analysis
Mycotoxins (MYTs), a class of low molecular weight secondary metabolites produced by filamentous fungi in food and feed, pose serious global threat to both human health and world economy. Due to their mutagenic, teratogenic, carcinogenic and immunosuppressive effects, the International Agency for Research on Cancer has classified various MYTs under Group 1 to 3 category with aflatoxins being designated under Group 1 category (carcinogenic to humans). Also, the presence of MYTs in trace amounts in diverse food matrices necessitates exploration of highly sensitive methods for onsite analysis. Although conventional chromatographic methods are highly sensitive, they are expensive, tedious and cannot …

Recently, demand for fermented foods has increased due to their improved nutritional value, taste, and health-promoting properties. Worldwide consumption of these products is increasing. Fermented foods are generally safe for human consumption. However, some toxins, primarily biogenic amines (putrescine, phenylethylamine, histamine, tyramine, and cadaverine), mycotoxins (fumonisins, aflatoxins, ochratoxin A, zearalenone, and trichothecenes), and bacterial toxins (endotoxins, enterotoxins, and emetic toxins) can be produced as a result of using an inappropriate starter culture, processing conditions, and improper storage. These toxins can cause a multitude of foodborne illnesses and can lead to cardiovascular aberration and adverse gastrointestinal symptoms. Analytical techniques are in …

Journal of Food and Drug Analysis
Polycyclic aromatic hydrocarbons (PAHs), a class of harmful and persistent organic contaminant, are widely distributed in the environment and eventually accumulated in water and food. Also, they are formed in different varieties and varying amounts during processing of food depending on the food composition, cooking method and processing condition. According to the International Agency for Research on Cancer (IARC), various PAHs are classified under Group 1 to 3 category, with Group 1 designated as carcinogenic to humans, Group 2A as probable carcinogen, Group 2B as possible carcinogen and Group 3 as noncarcinogenic.
