aflatoxins are toxins which are usually produced by a kind of aspergillus fungus named flavus, parasiticus, and numius. there are 18 kinds of aflatoxins have been discovered by scientists and aflatoxin b1 is the most toxic and carcinogenic. taking aflatoxins present in food causes lots of diseases like liver diseases, alcoholic liver, mutagenesis, and malformation in animals. it also has some o...

BACKGROUND Nuclear magnetic resonance (NMR) technique is a powerful analytical tool in determining the presence of bacterial contaminants in complex biological samples. In this paper, a portable NMR-based (pNMR) biosensor and assay to detect the foodborne bacteria Escherichia coli O157:H7 is reported. It uses antibody-functionalized polymer-coated magnetic nanoparticles as proximity biomarker o...

The objective of this study was to determine the effects of whole linseed supplementation on performances and milk fatty acid composition of dairy cows. Thirty six Holstein Friesian crossbred lactating dairy cows were blocked by milking days first and then stratified random balanced for milk yields and body weight into three groups of 12 cows each. The control group received 300 g of palm oil. ...

A collaborative study was conducted to evaluate the effectiveness of an immunoaffinity column cleanup liquid chromatographic method for determination of aflatoxin M1 in milk at proposed European regulatory limits. The test portion of liquid milk was centrifuged, filtered, and applied to an immunoaffinity column. The column was washed with water, and aflatoxin was eluted with pure acetonitrile. ...

with aim for identification of contaminative and critical points of raw milk during production in 9 selected industrial dairy farms, 408 raw milk samples were collected from udders, milking machine, cooling tank and milk transport vehicle at receiving platform in dairy plant. samples were examined for total microbial, coliform ande. coli count and also acidity and ph. total microbial count of s...

in this study, modified starch was used as a fat replacer in the milk. the fat replacer was manufactured from modified starch such as pre-gelatinized and cross–linked starches. modified starches were manufactured by hydrochloric acid and citric acid treatments from potato and wheat and were added to skim milk at concentrations of 0.15%, 0.30% and 0.45%. viscosity, total solid, fat content, titr...

Milk would be contaminated with Aflatoxin M1 (AFM1) if it was obtained from lactating animal which fed with feedstuffs containing Aflatoxin B1 (AFB1). AFM1 is classified as group 2B, possibly carcinogenic to humans and exposure to AFM1 through milk consumption is a public concern. The purpose of this study was to determine the AFM1 exposure through liquid milk consumption for adult consumers in...

Coxiella burnetii is the causative agent of the zoonotic disease Q fever, and ruminants being considered as the main source for human infection. Although the main route of infection in human is inhalation of contaminated aerosols, oral transmission by contaminated raw milk or unpasteurized dairy products is also a possible route of infection. Raw milk or dairy products produced from unpasteuriz...
