Abstract:
The objectives of this research was to study the optimization of durian paste by vacuum paste machine. The process of this research consisted of test durian stirred by vacuum paste machine under vacuum (600 mm.Hg) at various frying temperature at 40, 45 and 50 C, various frying time at 120, 135 and 150 minutes. To determine optimum frying condition was stirred by
computer program and the samples were subjected to physical, chemical and sensory evaluation. The data analysis were mean and standard deviation. The results showed that the optimization condition of durian paste was stirred at
temperature 45C and length of time 135 minutes. The highest of properties of durian paste were 76 Brix at temperature 50C and length of time 150 minutes, 0.75 Aw at temperature 40C and length of time 120 minutes, 38.59 colour(L) at temperature 40C and length of time 150 minutes, 10.66 colour(a) at temperature 50C and length of time 150 minutes and 24.15 colour(b) at temperature 50C and length of time 120 minutes. The sensory evaluation of durian paste colour,
odor, taste, texture and overall sensory, found it was significant different at 0.05 level. The highest acceptability was at the condition of temperature 45C and length of time 135 minutes.
