Development of pasteurized milk by added phenolic which extract from the moonflower (Ipomoea alba Linn.)

Abstract

The fresh moonflower (FM) was dried in hot air oven at 50 C 48 hours as the dried moonflower (DM) 7.37 %. Then, DM was extracted by ethanol concentration 95% and using the evaporator to evaporate ethanol solution. This study aimed to study the process which extract phenolic compounds (PC) from FM and formulate PC in pasteurized milk. From the results, PC was 68.11±1.44 μg/ml. The final formula of pasteurized milk was added PC 1g /200 ml and was pasteurized at 72 °C 15 s. The (L*) 85.91±0.07, (b *) -1.92±0.06, (a *) 17.13±0.24, pH 6.58±0.00, total soluble solid 12 ˚Brix. It could be stored at 4 C for 7 days.
