Particle size distribution of barley Talgan, prepared according to traditional and innovative technologies

Abstract

The purpose of the research was to analyze the fractional composition of the national Khakass product Talgan, prepared by traditional and innovative methods from barley grain of different varieties (Biom, Krasnoyarsk 91, Omsk Golozerny 1). The distribution of grain particles in Talgan by fractions was studied by the standard method of determination using grain sieves. It was found that in the product manufactured by innovative technology compared to traditional, the relative proportion of particles having a maximum size was lower, and the proportion of particles with smaller sizes was higher. On average, barley Talgan is respectively manufactured using innovative and traditional technology, the fraction of particles with sizes greater than 1 mm was 51.0 and 73.9%, the fraction smaller than 0.25 mm - 21.6 and 11.3%. It was found that for each barley variety the value of the grain grinding module for the innovative technology for Talgan production was lower compared to those for the traditional technology. It has been suggested that the previously recorded result of a higher total antioxidant content in barley Talgan, produced using innovative technology, was due, among other things, to more efficient extraction of antioxidants from smaller grain particles. Using two-factor analysis, it was found that the distribution of particles in Talgan at 80.9% depends on the technology of its preparation.
