| 摘 要： | 为了解高油分双低优质油菜冷榨菜胚油的品质特点及营养价值,并为其开发利用提供参考,采用脱皮冷榨工艺技术对高油分双低优质油菜进行加工,并对冷榨菜胚油进行检验分析。结果表明:冷榨菜胚油脂肪酸组成为12种,其中饱和脂肪酸5种,占总脂肪酸的6.7%;不饱和脂肪酸7种,占93.2%;不饱和脂肪酸油酸、亚油酸、亚麻酸分别占61.2%、16.6%和9.4%,与普通压榨菜籽油相比,油酸含量高9.6百分点、芥酸含量(2.5%)低10.2百分点,符合国标GB 1536—2004中低芥酸菜籽油的质量要求。维生素E含量为500.23mg/kg,植物甾醇含量为238.85 mg/100g;不含丁基羟基茴香醚(BHA)和二丁基羟基甲苯(BHT)食品添加剂,不产生反式脂肪酸。冷榨菜胚油色泽Y≤35、R≤4.0,具有菜籽油固有的气味和滋味、无异味,透明度为澄清透明;水分及挥发物≤0.1%,酸值≤2.1mg KOH/g,过氧化值≤1.5mmol/kg,加热时均无析出物、罗维朋比色黄色值不变、红色值未加深;溶剂残留量为0,均符合国标GB 1536—2004的质量要求。黄曲霉毒素B1≤2.50μg/kg,苯并(a)芘≤0.90μg/kg,总砷≤0.01mg/kg,铅≤0.09mg/kg,均优于国标GB 2716—2010食用植物油卫生标准限值。

| Abstract: | To explore the quality and nutrient values of cold-pressed embryo oil of high oil and doublelow rapeseed,and provide references for the exploitation and utilization,the high oil and double-low rapeseed was processed with peeled cold-pressed technology,and the embryo oil was detected and analyzed as well.Results:The cold-pressed embryo oil is consisted of 12 kinds of fatty acids,including five saturated fatty acids,accounting for 6.7％ of total fatty acids;seven unsaturated fatty acids (93.2％);oleic acid,linolic acid and linolenic acid account for 61.2％,16.6％ and 9.4％ in unsaturated fatty acids respectively.Compared with general cold-pressed rapeseed oil,the contents of oleic acid and erucic acid (2.5％) in cold-pressed embryo oil are respectively 9.6 percents higher and 10.2 percents lower,which meets the quality requirements in national standard GB 1536-2004.Contents of vitamin E and phytosterol are 500.23 mg/kg and 238.85 mg/100g respectively;BHA,BHT and trans-fatty acids cannot be detected in cold-pressed embryo oil.The cold-pressed embryo oil is of the color Y≤35 and R≤4.0,with innate smell and taste of rapeseed oil,without off-flavor,and it is clear and transparent;Moisture and volatile matter≤0.1％,acid value≤2.1 mg KOH/g,peroxide value≤1.5 mmol/kg,no educts when heated,no change of yellow value and no deepening of red value in lovibond test,the solvent residue is 0,all above meet the quality requirements of national standard GB 1536-2004.Aflatoxins B1≤2.50 μg/kg,benzo apyrene≤0.90 μg/kg,total As≤0.01 mg/kg,Pb≤0.09 mg/kg,all the indicators above are better than the sanitary standard of edible vegetable oil(GB 2716-2010). |
