การใช้สารฟีนอลิกจากดอกชมจันทร์ในการผลิตนมพาสเจอไรซ์

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.

Effect of extraction methods on mao berry marc properties
Effect of extraction methods on mao berry marc properties

In this study the mao berry marc which was divided into 5 varieties including Fapratan Phusung Phupanthong Yaykhamta and mixed variety were dried in tray dryer at low temperature (50?C) and high temperature (60?C) for 72 hr. All samples were investigated their properties including yield color water activity pH tannin total phenolic total anthocyanin antioxidant activity in term of %DPPH activity total microorganism and yeast & mold content. It was found that the yield color in term of ?h aw tannin and anthocyanin content of low temperature drying sample showed the highest value. However the total microorganism and yeast & mold content of high temperature drying samples were not present in all samples which less than those recommended in the Thai Community Product Standard (dried fruits: 136/2003). Eight trained-panelists were used for Hedonic scale (1-9 point) sensory evaluation including clarity color odor taste and overall linking of high temperature drying samples were similar in five varieties (P>0.05).
