PHOTOMETRIC METHOD TO DETECT DIACETYL IN BEER

摘要

FIELD: food industry.;SUBSTANCE: method includes detection of diacetyl concentration by comparison of optical densities of beer solution with addition of standardised solution of diacetyl and solution of beer, besides, concentration of diacetyl is determined by comparison of optical density growth in beer with diacetyl added to growth of beer solution optical density. Besides, growth of optical density of solutions is measured relative to arbitrary solution of comparison from the moment of reagents addition until maximum value of optical density is achieved.;EFFECT: simplified and improved accuracy of analysis.;1 dwg
