| description | Measurement of beer and intermediate hazes is an important part of modern brewing technology automation and control including laboratory analyses, total quality control and production of the shelf life of the final products. Regardless the fact that present brewers have at the disposal throughout theoretical and practical knowledge produce beer of market demanded product shelf life and appropriate colloidal or physical stability, time to time unwonted fluctuation of the product quality and process troubles can occur due to complicated mechanism of the ageing interactions of beer and intermediate colloid leading to business loss. At least, but not last a complex analyses of the processes of beer colloidal ageing is important for the knowledge and monitoring of flavour staling since both ageing processes are influenced by temperatures and other physical-chemical factors. One of the ways which can limit causes leading to unwanted beer ageing and improve quality of the final product is the innovation of both analytical methods and techniques based on beer and intermediates haze measurements enabling more precise and effective analyses of their colloidal and possibly flavour properties as well. It is shown in the present paper that substantial improvements is analyses of beer and intermediates colloids can be approached by innovative conception of unified brewing laboratory, bottle rotating turbidimeter capable of performing beer thermal ageing tests on intact commercial bottles provided with the modules from turbidimetric titrations of small volume samples in chemical tubes or vials or even more with process flow-through haze measuring cell simultaneously and two scattering angles, thus enabling to differ changes in the size of haze particles during ageing of technological processes. By means of complementation of turbidimetric titrations with simultaneous pH and or conductometric measurements the developed technique gives than cost effective estimation of basic electrokinetic parameters of beer and intermediates colloids which play and important role in beer ageing processes.(In Czech, English summary only) |
