The possibility of buckwheat application in the fermented malt technology t

Abstract

Rye is the traditional raw material for the fermented malt production. The article considers buckwheat grains application as an unconventional raw material. The research materials were rye of Vostok 2 breed and buckwheat of Dikul breed. Amylolytic capacity (AC) of malt was determined by colorimetric iodometric method, saccharification capacity (SC) - by polarimetric method, proteolytic (PC) - by refractometric method (according to Petrov); the humidity of the samples was determined on a thermographic infrared moisture meter FD 610. The extract, acidity and color of the fermented malt was determined according to GOST R 52061-2003. It was found that AC, SC and PC of buckwheat malt are 5.8% higher, 42.9% lower and 11.6% higher respectively than those of rye malt. Comparative characteristics of fermented buckwheat and rye malts showed that there is a decrease in the mass fraction of the extract and an increase in the color of buckwheat malt. This happens due to the hydrolysis of high-molecular compounds - carbohydrates, proteins to sugars and amino acids, respectively, due to the reactions of melanoid formation, which result in improved color, taste and aroma of malt. It was found that the use of buckwheat in fermented malt technology is possible, moreover, it is a gluten-free raw material due to the low content of the gluten fraction of the protein and can be applied to a wide range of consumers, including those suffering from gluten intolerance. But to increase its extractiveness, it is desirable to use enzyme preparations at the malting stage. The novelty of the proposed technical solution is confirmed by the RF patent for invention No. 2603268 "Method for the production of fermented buckwheat malt".
