Pengaruh Perbandingan Jumlah Starter dan Konsentrasi Agar pada Pembuatan Yogurt dari Sari Biji Nangka

The aim of this study to determine the effect of adding the amount of Starter and Agar concentration to yogurt of jackfruit seed juice. Total of Starters (S) consisting of 4 levels, namely: S 1 = 2%, S 2 = 4%, S 3 = 6% and S 4 = 8%. The second factor is Concentration of Agar (A) which consists of 4 levels, namely: A 0 = 0%, A 1 = 0.3%, A 2 = 0.6% and A 3 = 0.9%. Parameters observed included: yield, TSS, pH, organoleptics (color, taste, and texture). The results of statistical analysis showed that the number of static concentrations had a very significant effect (P <0.01) on yield, TSS, pH and taste, but did not differ significantly (P <0.05) on color and texture. The amount of agar concentration had a very significant effect (P <0.01) on yield, TSS and texture, but it was not significantly different (P <0.05) on pH, color and taste.
