摘　　要：为制定营养均衡的高端食用油品质策略,满足人们日益增长的油脂健康摄入需要。以茶叶籽油为基油,稻米油、葵花籽油和亚麻籽油为辅油,制备一款营养平衡且兼顾价格的茶叶籽调和油。采用气相色谱-质谱法检测各原油脂肪酸含量,利用线性规划数学模型,对调和油脂肪酸配比进行优化,得到茶叶籽调和油的最佳调配比例,并对其进行货架期的预测。结果表明,茶叶籽油、稻米油、葵花籽油、亚麻籽油过氧化值和酸价等指标都符合食用植物油国家相关标准,调配的最适比例为35%、26.4%、25.4%、13.2%,单不饱和脂肪酸(Monounsaturated fatty acid,MUFA):多不饱和脂肪酸(Polyunsaturated fatty acid,PUFA)为1.08:1,n-6 PUFA与n-3 PUFA的比值为4.58:1,在4:1至6:1之间,同时角鲨烯含量为792.3 mg/kg、谷维素含量为5500 mg/kg、维生素E含量为218 mg/kg及总甾醇含量为7077 mg/kg。茶叶籽调和油保质期不低于18个月,单价为16.8元/100 mL,较茶叶籽油下降61.5%。茶叶籽调和油满足消费者对营养及价格的需求,试验结果可为茶叶籽调和油的产业化提供技术参考。In order to develop a strategy for producing high-quality edible oil with balanced nutrition that meets the increasing demand for healthy fat intake,we aim to prepare a nutritionally balanced and costeffective Camellia seed blended oil by using tea seed oil as the base oil and incorporating rice bran oil,sunflower seed oil,and flaxssed oil as auxiliary oils.The fatty acid content of each oil was determined by gas chromatography-mass spectrometry(GC-MS).A linear programming mathematical model was employed to optimize the ratio of fatty acids in blended edible oils,resulting in the ideal blending proportion for tea seed oil.Additionally,a shelf life prediction was conducted for the blended oil.The results indicated that the indexes such as peroxide value and acid value of tea seed oil,rice bran oil,sunflower seed oil,and flaxseed oil complied with the relevant national standards for edible vegetable oils.The optimal blending ratio was 35%for tea seed oil,26.4%for rice bran oil,25.4%for sunflower oil,and 13.2%for flaxseed oil.The ratio of monounsaturated fatty acid(MUFA)to polyunsaturated fatty acid(PUFA)is 1.08:1,while the ratio of n-6 PUFA to n-3PUFA was 4.58:1,which falls within the range of 4:1–6:1.Furthermore,the content of squalene was 792.3 mg/kg,oryzanol was 5500 mg/kg,vitamin E was 218 mg/kg,and total sterol is 7077 mg/kg.The blended tea seed oil has a minimum shelf life of 18 months,with a unit price of 16.8 yuan per 100 mL,representing a significant decrease of 61.5%compared to pure tea seed oil.This blended tea seed oil satisfy consumers'demands for both nutrition and affordability,while the present study provides a reference for the industrialization of blended tea seed oil.
