作者鲍赛（2019）在《桑葚籽油提取技术及性质研究》一文中研究指出：目前我国食用油产量仅能满足市场需求量的1/4,国产食用油缺口较大,并且存在食品资源综合利用率偏低的现象。桑葚籽是桑葚产品加工过程中容易被人废弃和忽略的副产物,但实际上桑籽中营养丰富,尤其油脂是桑葚籽中含量最多的成分,作为油料供给对象能体现出一些常见油料中没有的特殊功效,是可以得到最广泛应用的对象。综合开发利用桑葚籽资源,对提高资源综合利用率,促进我国桑葚产业的快速发展都有着重要的现实意义和经济意义。本文以桑葚籽为研究对象,研究了桑葚籽成分组成,桑葚籽油（MSO）的有效提取及性质研究,并给出桑葚原油产品标准基本指标参考范围。主要研究结果如下:（1）通过单因素实验及正交实验确定直接溶剂浸提法提取MSO的最佳提取工艺条件:正己烷溶剂下,浸提时间8h、浸提温度70℃、料液比1:15,在此条件下进行验证实验,重复测定3次,测得葚籽油的提取率为84.22±0.586%。（2）根据单因素和正交实验,超声辅助浸出法的最佳工艺条件:料液比1:15、超声功率300W、超声时间40min、超声温度50℃,在此条件下,重复测定三次,桑葚籽油的提取率为91.25±0.734%。根据单因素实验和响应面法,MSO提取的最佳微波辅助工艺为料液比1:17、微波时间22min、微波温度75℃,微波功率400W,实际测得的MSO提取率为93.05±0.53%。（3）对机械压榨法、溶剂浸提法、超声辅助法和微波辅助法提取MSO进行性质研究,色泽:黄65.0,红4.4;黄63.9,红2.2;黄64.8,红1.8;黄65.4,红2.0。气味滋味:均具有桑葚籽油独特的香味和滋味,无异味。水分及挥发物:0.19±0.625%,0.20±0.200%,0.20±0.153%,0.20±0.436%。不溶性杂质:0.16±0.200%,0.17±0.153%,0.17±0.153%,0.16±0.265%。酸价:6.93 mg/g±1.15%,6.24 mg/g±1.00%,6.17 mg/g±0.577%,6.19 mg/g±0.577%。过氧化值:0.12g/100g±0.577%,0.068g/100g±0.0577%,0.061g/100g±0.153%,0.058g/100g±0.306%。相对密度(d2020):0.926±0.0115%,0.920±0.0153%,0.919±0.0208%,0.919±0.0115%。维生素E:321 mg/kg,650 mg/kg,673 mg/kg,734 mg/kg。黄酮:14 mg/kg,19 mg/kg,22 mg/kg,20 mg/kg。（4）桑葚原油产品标准基本指标参考:气味滋味:具有MSO独特的香味和滋味,无异味;水分及挥发物（%）:≤0.20;不溶性杂质（%）:≤0.20;酸价（KOH,mg/g）:≤10;过氧化值（g/100g）≤0.20;相对密度(d2020):0.918-0.927。（5）通过GC-MS分析表明,MSO含有的脂肪酸集中于C14～C30,不饱和脂肪酸含量占81.13%～84.57%,成分组成为亚油酸70.25%～72.23%,油酸8.8%～9.3%,棕榈酸8.21%～8.77%,硬脂酸3.95%～4.14%,角鲨烯1.84%～2.79%,棕榈油酸0.18%～0.25%,肉豆蔻酸0.06%～0.11%。与橄榄油和大豆油相比MSO的亚油酸（C18:2n6c）含量最高,分别高出61.13%～63.11%和34.87%～36.85%。MSO中测定出在其他两个油品中均未发现的特有角鲨烯和肉豆蔻酸。
