THE EFFECT OF ADDITIONAL ARABICA GROUND COFFEE ON THE FERMENTATION PROCESS ON ORGANOLEPTIC QUALITY OF COW’S MILK KEFIR

Abstract

This study aims to determine the effect of adding arabica ground coffee to the fermentation process on the orga- noleptic quality of cow’s milk kefir. The experimental design used was a completely randomized design (CRD) with five treatments and three replications, namely kefir with the addition of 0% arabica ground coffee (P0), kefir with the addition of 1% arabica ground coffee (P1), kefir with the addition of 2% arabica ground coffee. (P2), kefir with the addition of 3% arabica ground coffee (P3) and kefir with the addition of 4% arabica ground coffee (P4). The va- riables observed include color, aroma, taste, texture and overall acceptance. Analysis on color, aroma and taste sho- wed significantly different results (P <0.05) with a numerical scale of 3-4.72 respectively from white to light brown, 2.76-4.88 from sour to coffee flavored and 2.76-4.68 from very sour to bitter acid. Analysis on texture showed that P0 and P1 were not significantly different (P> 0.05) but P2, P3 and P4 were significantly different (P <0.05) from P0 with a numerical scale of 3-3.52 from ordinary to slightly soft. The analysis of the level of liking on the overall acceptance shows that P0, P1 and P2 are not significantly different (P>0,05), but P3 and P4 are significantly diffe- rent (P<0,05) with a numerical scale of 3.08-4.36 from ordinary to like. Based on the results of this study, it can be concluded that the addition of 4% Arabica ground coffee is the most preferred by the panelists.
