汽爆预处理对油莎豆组分、微观结构 及油脂提取率的影响Effects of steam explosion pretreatment on composition, microstructure and oil extraction rate of Cyperus esculentus

open access: yesZhongguo youzhi
旨在提高油莎豆油的提取率,对油莎豆进行不同时间的汽爆预处理,探究汽爆预处理对油莎豆的化学组分、微观结构以及油脂提取率的影响。结果显示:汽爆预处理使油莎豆的脂溶物和水溶物含量增加,纤维素、半纤维素和果胶含量减少,木质素含量增加;汽爆预处理使油莎豆细胞壁主要化学键发生断裂或修饰;汽爆(30 min)后油莎豆形状发生明显变化,细胞间裂缝变大,细胞结构破损,排列杂乱;汽爆后油莎豆的油脂提取率增至18.41%,比汽爆前(14.58%)提高26.27%。综上,汽爆破壁促进油莎豆油提取的方法是可行的。In order

精炼过程对油莎豆油品质的影响Effect of refining process on quality of Cyperus esculentus L.oil

open access: yesZhongguo youzhi
旨在为油莎豆油的精深加工提供参考,对低温压榨油莎豆原油进行精炼,分析不同精炼工序(脱胶、脱酸、脱色、脱臭)油莎豆油的理化性质、营养成分和抗氧化能力,并对各指标进行相关性分析,明确精炼过程对油莎豆油品质的影响。结果表明:与油莎豆原油相比,脱胶可显著降低油莎豆油的过氧化值,磷脂含量和(γ+β)-、δ-生育酚含量;脱酸显著降低油莎豆油的酸值、总酚含量和α-生育酚含量;脱色显著提高油莎豆油的色度值a*绝对值和L*值,改变其挥发性成分的组成,降低色度值b*值、总酚含量和抗氧化能力,同时损失大量的生育酚 ...
