Prevalence and mitigation of aflatoxins in Kenya (1960-to date) [PDF]

, 2018
Aflatoxins are highly toxic metabolites of several Aspergillus species widely distributed throughout the environment. These toxins have adverse effects on humans and livestock at a few micrograms per kilogram (μg/kg) concentrations. Strict regulations on

Metal nanostructure‐coupled label‐free localized surface plasmon resonance biosensors for rapid and sensitive disease diagnosis

BMEMat, EarlyView.
LSPR biosensing enables rapid, sensitive, and low‐sample‐volume detection of biomarkers, with broad applications in diagnosing cancer, infectious, and chronic diseases. Advances in nanostructure design, micro/nanofabrication, and microfluidic integration have expanded the potential of LSPR sensors in biomedical diagnostics.

STUDY ON THE IMPORTANCE OF AFLATOXINS; DEGRADATION METHODS; MYCOTOXINS PREVALENT IN CORN

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2021
Aflatoxins are mycotoxins produced by fungi of the genus Aspergillus. The species Aspergillus flavus and Aspergillus parasiticus are the main responsible for the appearance of the main types of aflatoxins: aflatoxin B1, aflatoxin B2, aflatoxin G1 ...

Pulsed Light Technology in Food Safety and Preservation: Principles, Applications, and Future Directions

Food Chemistry International, EarlyView.
Pulsed light technology uses short high‐intensity broad‐spectrum flashes (200–1100 nm) to inactivate microbes via DNA damage. It preserves food quality, extends shelf life, and works on liquids, meats, and produce, often combined with other hurdles for enhanced efficacy.

Determination of Aflatoxins and Selected Heavy Metals in Rice Varieties Cultivated in Fogera, Amhara Region, Ethiopia

Food Chemistry International, EarlyView.
ABSTRACT Rice (Oryza sativa L.) is a vital staple crop for nearly half the world's population. This study investigates the levels of aflatoxins (AFB1, AFB2, AFG1, and AFG2) and selected heavy metals (Cd, Pb, and Cr) and essential elements (Mn, Fe, Mg, Cu, and Zn) in rice varieties cultivated in Fogera, Amhara Region, Ethiopia.

Extraction aflatoxins from cereals using agerogel @ COF composite and evaluating ultraviolet and microwave irradiation and sonication effect on their decontamination

Food Chemistry: X
A dispersive solid-phase extraction method was proposed for the extraction of aflatoxins (B1, B2, G1, and G2) from cereal samples. A covalent-organic framework and graphene aerogel composite were evaluated for their capacity to extract and preconcentrate

Aflatoxins: characteristics and impact on human health

, 2017
Some molds commonly occurring in the natural environment produce mycotoxins in the process of secondary metabolism. Aspergillus flavus and A. parasiticus are species of molds, which are responsible for the production of aflatoxins and are crucial in the ...
