Sekundarni naslov: | Experimental determination of the influence of process parameters in kefir grain production with a statistical method |
Sekundarni povzetek: | In this diploma work the experimental determination of the optimum process parameters for kefir grain production, as well as the determination of the contribution of the process parameters at the optimal conditions for kefir grains is described. All experiments have bean carried out in a laboratory batch reactor (reaction calorimeter RC1e). According to scientific, data we have chosen for the optimization parameters the temperature of the growth medium, the mass concentration of glucose and yeasts as well as the degree of agitation. According to Taguchi’s principles we have planed a partial factorial experiment with the above mentioned optimization criteria. Every trail took 24 hours. The experimental results have been processed with the analysis of variance which has, at optimal conditions for kefir grain growth, given the contribution of the separate optimization criteria. In the second part of the experimental work we have evaluated the influence of different cow milk types on kefir grain growth at the above determined conditions. Scientific data indicated a correlation between kefir grain growth and the milk fat content. But we have been unable to confirm such a correlation. |
