Total Bakteri Asam Laktat, Nilai Ph Dan Sifat Organoleptik Drink Yoghurt Dari Susu Sapi Yang Diperkaya Dengan Ekstrak Buah Mangga

Mango extract contains sugars that are supposed to stimulate growth and increase the activity of lactic acid bacteria (LAB). This research was carried out to investigate the effect of the addition of mango extract on total LAB, pH value and organoleptic properties (sour taste and creamy texture) of drink yoghurt. Total LAB and pH value was arranged in completely randomized design (CRD) with 4 treatments and 5 replications, if there is a treatment effect followed by Duncan Multiple Test Area. Test the organoleptic properties using organoleptic test by 25 panelists. The treatments given is the addition of mango extract as much as 0% (T0), 1% (T1), 3% (T2) and 5% (T3). The results showed that the addition of mango extract (0, 1, 3 and 5%) gave a significant influence (P<0,05) the pH value and creamy texture, while the total LAB and sour taste gave a not significant influence (P>0,05). Total LAB generate a number 7,57462 to 7,97472 log (CFU/ml); pH value of 4,548 to 4,798; sour taste from 3,24 to 3,36 and creamy texture from 2,2 to 2,96. Conclusions of this research were drink yoghurt containing 1% mango extract has the best quality as the diversification product
