Abstract

This research aims to determine the treatment given on the manufacture of low-fat milk cheese added with bay leaf powder with different percentages on yield, color, and total lactic acid. The materials used were 20 liters of commercial low-fat milk, 100 g of bay leaf powder, 1 g of mesophilic bacteria, 20 ml of liquid rennet, 400 g of skim milk, 4 g of CaCl2, 200 ml of distilled water, 1 liter of NaOH solution, 50 ml of phenolphthalein color indicator. The obtained research were analyzed by completely randomized design (CRD) with 5 treatments and 4 replications with an orthogonal polynomial. The treatments included P0: without the addition of bay leaf powder, P1: 0.25% of bay leaf powder, P2: 0.50% of bay leaf powder, P3: 0.75% of bay leaf powder, and P4: 1% of bay leaf powder. The results showed there was a highly significant effect (P<0.01) on the color indicator L* (+light, -dark), significant effect on a*(+red, -green), and highly significant on whiteness index which was further tested with orthogonal polynomials having a descending parabolic quadratic line while the yield, color indicator b*, and total lactic acid had no effect (P>0.05) the addition of bay leaf powder. Total value of average yield 13.57 ± 1.87; color L* 42.47 ± 8.03; a* 3.78 ± 2.09; b* 22.66 ± 1.48; whiteness index 37.91 ± 7.24; and total lactic acid 2.75 ± 0.55. The addition of bay leaf powder with different percentages can change the color of the cheese to darker and dark green.
