Assessment of Aflatoxins in Processed Foods Biology Essay
A study conducted in Malawi and Zambia to assess the extent of mold and mycotoxin contamination in commonly processed cassava products concluded that the cassava products analyzed were safe for human consumption. Strains of the Aspergillus fungi, especially A. flavus and A. parasiticus, mainly produce aflatoxins that 1.2. The food safety risk associated with peanut butter. Associated with peanut butter, microbial contamination, specifically by Salmonella spp. and biological toxins in the form of aflatoxin are the major food safety concerns of peanut butter that have been consistently reported in recent years12,13,14,15. Although these critical aflatoxins are fungal metabolites found in animal feeds and foods. When ruminants eat feed containing Aflatoxin B1 AFB1, this toxin is metabolized and Aflatoxin M1 AFM1 is excreted into the milk. International Agency for Research on Cancer IARC classifies AFB AFM human carcinogens belonging to and. In the event that the contaminated food is processed, aflatoxins enter the general food supply and can cause serious illness. Aflatoxins are unevenly distributed in food and raw materials, making their eradication both a scientific and technological challenge. Cooking, freezing or pressurizing have little effect on aflatoxins. Mycotoxins are naturally occurring toxins that, under certain conditions, contaminate various crops and foods during harvesting, handling, storage and processing. Neither dietary mycotoxin intake in Cameroon is well characterized, nor its health effects on consumers. This revision is intended as the first milestone. The carcinogenic nature of aflatoxins, mainly produced by Aspergillus flavus and Aspergillus parasiticus, poses a major threat to humans and animals and is also an economic problem, especially in tropical and subtropical countries where environmental conditions favor the growth of fungi. These conditions increase the possibility of aflatoxin contamination. Aflatoxin contamination in foods is a critical health challenge for low- and middle-income countries in subtropical regions. Maize Zea mays L., a staple food most commonly grown in Africa, including Ghana, and widely consumed as many as three times a day, is a source of aflatoxin contamination due to its susceptibility to mold. Aflatoxins are mainly released by Aspergillus flavus and Aspergillus parasiticus. AFB is the most harmful type of aflatoxins and is a potent hepatocarcinogen, mutagenic and teratogen. Aflatoxins AFs are the major toxic, mutagenic, and carcinogenic fungal toxins that routinely contaminate food and feed. Although more AFs have been identified to date, aflatoxin B1, Abstract. Aflatoxins are carcinogenic secondary metabolites produced by Aspergillus section Flavi that contaminate a wide variety of food and feed products and are responsible for serious health and economic consequences. Fermented foods are prepared with a wide variety of substrates over a long fermentation time and are thus vulnerable to: 14.3.4. Criteria. The main steps for reducing aflatoxins ∑R in peeled peanuts are: color sorting, blanching and roasting. Roasting peanuts is practiced at various time-temperature combinations, -160 C -185 C - or higher temperatures such as C - Aflatoxins AFs are frequent contaminants in crops worldwide and can cause adverse.
