Sažetak
About 70 million people around the world obtain more than 500 calories per day from cassava and its flour. It has a great ability of productivity on marginal soils ; ability to resist drought, disease, and pests, and its harvest dates are highly flexible making cassava a remarkably adaptable and resistant crop. One of the main goals for this type of research should be development of quick, low cost analysis methods for cassava and cassava flour composition. The goal of this paper is to measure and analyze the photoacoustic spectrum of cassava flour and its constituting particle fractions. Photoacoustic spectrum measuring methods have a great potential for quick “ in the field” approach to cassava flour analysis and quality control. Photoacoustic spectrum of individual cassava flour fractions does show a remarkable and noticeable differentiation between the fractions. This is a result of two sets of influence, first set is the notable difference in fractional composition of cassava flour, and the second is rooted in the basic physical properties of the samples such as geometrical and spatial positioning and its influence on Photoacoustic signal strength. Results will show the possibility of quick quality control of cassava flour.
