D. Bicanic et al., PHOTOACOUSTIC AND PHOTOTHERMAL METHODS AS A TOOL TO AID AUTHENTICITY TESTS AND QUALITY ASSESSMENT OF FOODS, Progress in Natural Science, 6, 1996, pp. 573-576
Results of several experiments aimed at testing authenticity and at in
specting quality of foodstuffs are presented. Adulteration of red papr
ika spice by red lead, the effect of thermal treatment on stability of
