Abstract:
... For a rapid, specific and sensitive identification of cows', ewes' and goats' milk in mono-species Sicilian dairy products, species-specific duplex-PCR protocol was applied. DNA samples from blood and experimental cheeses of Sicilian autochthonous breeds were extracted to amplify the 12S rRNA (and part of 16S rRNA in case of Ovis aries) mitochondrial species-specific gene fragment. The use of spec ...

Abstract:
... Illegal adulteration of melamine in animal feed and food has been widely studied. However, the risk of using substitute non-protein nitrogen substances still exists. In this study, we developed the ¹³C NMR method for the detection of non-protein nitrogen substance adulteration in animal feed. Three compounds, i.e., urea, melamine, and biuret, were used for method development. We found that the che ...

Abstract:
... High-field and low-field proton NMR spectroscopy were used to analyse lipophilic extracts from ground roast coffees. Using a sample preparation method that produced concentrated extracts, a small marker peak at 3.16 ppm was observed in 30 Arabica coffees of assured origin. This signal has previously been believed absent from Arabicas, and has been used as a marker for detecting adulteration with r ...

Abstract:
... Adulteration of meat in processed food is a sensitive issue since certain meat species are prohibited in some religions such as Islam and Judaism. Some meat types are also potential carrier of some deadly diseases such as severe acute respiratory syndrome, anthrax, and hepatitis. Furthermore, unconscious consumption of certain meat might lead to an allergic reaction. Feline meat is not only taboo ...

Abstract:
... Due to their high market value, meat products are often targets for species substitution and adulteration. DNA-based methods are recognized as the most appropriate means to detect such fraudulent practices, however, these have not been extensively employed for the authentication of meat products available in South Africa. The aim of this study was to utilize a variety of molecular techniques to ev ...

Abstract:
... A novel closed-tube loop-mediated isothermal amplification (LAMP) was developed to detect goat milk adulterated with cow milk. The reaction results of the LAMP assay developed, identified using both visual observation and agarose gel electrophoresis, were completely consistent, indicating that visual observation was suitable and efficient to judge the final LAMP results. The specificity of LAMP as ...

Abstract:
... Milk processing industries and distributors have problems with adulteration of liquid milk by the addition of bovine cheese whey. Recently, the detection of fraudulent manipulation of milk with whey has focused on the identification of glycomacropeptide (GMP). Current non-immunological methods to detect GMP in dairy products are expensive and time-consuming or have low sensitivity. In this study, ...

Abstract:
... A highly specific single step polymerase chain reaction (PCR) is described for the detection of goat (Capra hircus) meat. Goat-specific primers (DAF-01 and DGR-04) were designed against a conserved region of mitochondrial d-loop gene that yielded a 294bp PCR product. Specificity of the primers was confirmed by testing them with DNA from other commonly used meat animal species, i.e., cattle, buffal ...

Abstract:
... A highly species-specific polymerase chain reaction (PCR) was developed for authentic identification of raw and heat treated sheep meat (mutton). Oligonucleotide primers were designed against a unique target region of sheep mitochondrial D-loop, that yielded four PCR products upon gel electrophoresis of which two amplicons of molecular size 329 and 404bp were found highly diagnostic. Chances of cr ...

Abstract:
... Food forgery has posed considerable risk to public health, religious rituals, personal budget and wildlife. Pig, dog, cat, rat and monkey meat are restricted in most religions, but their sporadic adulteration are rampant. Market controllers need a low-cost but reliable technique to track and trace suspected species in the food chain. Considering the need, here we documented a lab-on-a-chip-based m ...

The immunosensor was constructed by first electrochemically reducing 4-carboxyphenyl diazonium salt, which had been electrochemically generated in situ, to a stable 4-carboxyphenyl layer on carbon nanofiber-modified screen printed electrode. Antibodies were covalently attached ...

Abstract:
... Food fraud or food adulteration may be of forensic interest for instance in the case of suspected deliberate mislabeling. On account of its potential health benefits and nutritional qualities, geographical origin determination of olive oil might be of special interest. The use of a likelihood ratio (LR) model has certain advantages in contrast to typical chemometric methods because the LR model ta ...
