摘要
食用植物油具有高营养含量和抗氧化来源,对健康有益。为此,本研究对菖蒲(Citrofortunella microcarpa)、芙蓉(Hibiscus sabdariffa)和菠萝蜜(Artocarpus heterophyllus)种子进行了一系列的实验研究和分析,以评价其油脂提取的可行性和性能。研究了提取的种子油的产率、抗氧化活性、碘值、皂化值和过氧化值。结果表明,在3种种子中,菖蒲种子的产量最高,达32.7%,其次是玫瑰茄种子,产量为11.00%,菠萝蜜种子的产量最高,仅为0.60%。抗氧化活性研究表明,与EC50为109.74 mg/mL的菖蒲相比,EC50为49.04 mg/mL的玫瑰茄具有更强的抗氧化性能。对未加热油测定的碘值为100.83 g /100g油和110.60 g /100g油,将玫瑰花籽油和菖蒲籽油归为非干性油类,加热效果显示,由于油中不饱和的损失,碘值略有下降。加热后,菖蒲籽油和玫瑰茄籽油的皂化值均无显著降低。在不加热条件下,玫瑰和菖蒲籽油的过氧化值分别为10.36 meq/kg和24.86 meq/kg。
Physical and chemical characterization of oil extracted from Citrofortunella microcarpa, Hibiscus sabdariffa and Artocarpus heterophyllus seeds
Consumable plant oils had been related with highly nutritional content and antioxidant source that provide crucial health benefits. Hence, in this study a series of experimental work and analysis were conducted to evaluate the practicability and the properties of oil extraction from seeds of calamansi (Citrofortunella microcarpa), roselle (Hibiscus sabdariffa), and jackfruit (Artocarpus heterophyllus). The yield, antioxidant activities, iodine value, saponification value, and peroxide value of extracted seed oils were studied. Results obtained shown that among the three seeds species, calamansi seeds resulted in the highest yield of 32.7%, followed by roselle seeds with a yield of 11.00% and lastly, jackfruit seeds with the highest yield obtained was only 0.60%. Antioxidant activities conducted has shown that roselle with EC50 of 49.04 mg/mL has greater antioxidant properties as compared with calamansi with EC50 of 109.74 mg/mL. Iodine value determined for unheated oil has resulted in a value of 100.83 g I2/100g oil and 110.60 g I2/100g oil that has classified roselle and calamansi seeds oil under the non-drying oil categories and heating effect shown a slight decrease in the iodine value due to loss of unsaturation within the oil. Both calamansi and roselle seed oils did not show significance reduction in saponification value upon heating. Peroxide value for roselle and calamansi seeds oil under unheated condition was determined to be 10.36 meq/kg and 24.86 meq/kg respectively.
