Abstract

This research was carried out to investigate the effect of three factors related with cold-pressing technology including pressing temperature, moisture content and shell content on the acid value, moisture and volatile matter content and yield of peanut oil with method of orthogonal experiment of 3 factors and 3 levels. The results showed that moisture content of peanut kernels had the most significant effect on yield and quality of peanut oil, followed by pressing temperature and shell content. When consider the acid value-oriented, the pressing temperature impacted mostly, followed by moisture content and shell content. The oil temperature of 65 , moisture content of 7% and shell content of 21% were proved to be the optimum technological conditions, under which the acid value of oil was 0.133, the moisture and volatile matter content of peanut oil was 0.015%, and the oil yield could reach up to 39.8%. The method of squeezing peanut oil in the low temperature is an ideal way to produce peanut oil due to the fact that the physical and chemical indicators of oil meet the national standard, and even better than the national standard.
