| 摘 要： | 采用GC-FIR法对苹果籽加工过程中的植物甾醇进行了成分分析。结果表明,苹果籽油中植物甾醇主要成分为菜油甾醇、豆甾醇和β-谷甾醇,其中以β-谷甾醇含量最高;压榨法制备的苹果籽油植物甾醇的含量(385mg/100g)高于索氏提取(288mg/100g)和超声提取法(318mg/100g);且随着苹果籽油精炼程度提高,油脂中的有益微量成分植物甾醇损失增大。 |

| Abstract: | Apple seed oil was extracted in different extraction methods from apple seed,and its phytosterols compositions were analyzed by GC-FIR.Results showed that campesterol,stigmasterol and β-sitosterol were main phytosterols components,and β-sitosterol was the major fraction in apple seed oil.Content of phystosterols reached(385mg/100g) by cold pressing extraction method,which was much higher than that of Soxhlet extraction(288mg/100g) and ultrasonic extraction(318mg/100g).With the degree of refining improving,content loss of phytosterols,the beneficial trace elements,became higher. |
| Keywords: | apple seed oil flow direction and distribution pattern phytosterols |
