Optimization of Oil Extraction Process from Jatropha curcas Seed and the Analysis of Crude Protein Content in Meal
摘要
Abstract
The test was aimed to optimize the oil extraction process from Jatropha curcas seed and analyzed the crude protein content in meal.Jatropha curcas seeds were selected as the experimental material,and the effects of solid to liquid ratio,temperature and extraction time on the oil extraction rate and crude protein content of meal were investigated and optimized.The results of single factor test showed that when the solid to liquid ratio was 1 ∶ 18,the temperature was 40 ℃ and extraction time was 30 min,the oil extraction rate was highest which was the 38.22％,32.21％ and 34.13％,respectively.The variance analysis results showed that the order of factors that affected the oil extraction rate were temperature＞solid to liquid ratio＞extraction time.The effects of temperature and solid to liquid ratio were extremely significant (P＜0.01).The extraction time did not have a significant effect on oil extraction rate (P＞0.05).The order of factors that affected the crude protein content in seed meal were temperature＞extraction time＞solid to liquid ratio.The effect of temperature was extremely significant (P＜0.01) and that of the extraction time was significant (P＜0.05).The results of orthogonal experiment showed that the optimal extraction conditions was AaB3Ca of which the solid to liquid ratio was 1 ∶ 22,temperature was 50 ℃ and extraction time was 50 min.The oil extraction rate was 39.41％,and the crude protein was 24.13％ under this condition.This study provided the theoretical basis for the development and application of Jatropha curcas seed.关键词
