BACKGROUND Food fraud/adulteration has ever increasingly become a dominant food issue of the modern world in both developed and developing countries. It is presumed that globalisation is mainly one of the underlying reasons. OBJECTIVES To assess and analyse the occurrence of food fraud on the Polish market during 2005-2012. MATERIAL AND METHODS Adulteration of foodstuffs was determined from...

Goats’ milk adulteration with cows’ milk is becoming a big problem. In the past, the urea-polyacrylamide gel electrophoresis assay with different motility of αS1-casein has been applied for the identification of cows’ milk adulteration. The detection sensitivity is 1.0%. The aim of this study was to develop a faster and more sensitive method to detect cows’ milk which may be present in adultera...

This paper proposes the use of the least-squares support vector machine (LS-SVM) as an alternative multivariate calibration method for the simultaneous quantification of some common adulterants (starch, whey or sucrose) found in powdered milk samples, using NIR spectroscopy with direct measurements by diffuse reflectance. Due to the spectral differences of the three adulterants a nonlinear beha...

Biodiesel has emerged as an alternative to non-renewable diesel fuel. Growing demand for biodiesel has given birth to mal practices such as adulteration which degrade its quality. The present study has dealt with the optimization of biodiesel production from Jatropha curcas oil using a five-level-four-factorial central composite design based on response surface methodology in 54 experimental ru...
