Abstract:
In the production of reduced fat coconut milk ice cream, ingredients were devided into 2 parts that were liquid (coconut milk, water) and dry (stabilizer and emulsifier, sugar, skim milk powder, salt, fat replacer). Liquid ingredients were combined and heated to 60 deg C, dry ingredients were added, mixed and pasteurized at 80 deg C for 2 minutes, then cooled and kept at 4 deg C for 24 hours. After ice cream mix was frozen, it was kept at -30 deg C for 24 hours. Results revealed that 0.45 percent Palsgaard 5944 gave highest percent verrun, 52.52 percent, than 0.45 percent Palsgaard 5924 and 0.40 percent Meyprogen 3325 and tended to have higher preferences in colour, coconut milk flavour, creaminess, gumminess, melting in mouth and overall acceptance. The formula with 8 percent coconut milk fat, 11 percent sugar, 20 percent skim milk powder and 0.45 percent Palsgaard 5944 was used as the control and found that the used of Simplesse - D 100 with 2 percent fat gave the physical properties of ice cream closed to the control and did not show any significant difference (p > 0.05) in coconut milk flavour, creaminess, gumminess and melting in mouth. Sample with 1.5 percent fat and Prolo - 11 as fat replacer gave significant (p < 0.05) lower melting rate than those with 1.0 percent, 0.5 percent and 0.0 percent fat. It gave maximum overrun with preference score closed to the control. When carbohydrate based fat replacers were used, results revealed that combination of Simplesse - D 100 and N - Lite D (1 : 2) did not show any significant difference in overrun was high at 61.02 percent. Whereas combination of Prolo - 11 with Mt - 01 (1:1) had higher preference score than Prolo - 11 alone (p < 0.05). After storage at - 30 deg C for 8 weeks, it was found that the formulas with good flavour and smoothness were those with Simplesse - D 100 combined with - starch (1 : 2) and Prolo - 11 combined with MT - 01 (1:4). Furthermore, Simplesse - D 100 with - Starch (1 : 2) gave more similar properties to the control than Prolo = 11 with MT - 01 (1 : 4), except viscosity and percent overrun, whereas melting rate, texture, smoothness and flavour were not significant difference (p > 0.05) from the control.
