不同脱酸工艺对红花籽油储藏品质的影响Effect of deacidification process on storage quality of safflower seed oil
Zhongguo youzhi, 2023 为了选择合适的脱酸工艺，提高红花籽油的储藏品质，以脱胶红花籽油为原料，采用碱炼脱酸和超声波辅助乙醇萃取（UAEE）脱酸工艺制备脱酸红花籽油，并采用Schaal烘箱法进行加速氧化试验，比较加速氧化期间脱酸红花籽油的理化指标（酸值、过氧化值、p-茴香胺值）、脂质伴随物（α-生育酚、总酚、总甾醇）含量，以及体外抗氧化能力（DPPH、ABTS自由基清除能力），对比分析2种脱酸工艺对红花籽油储藏品质的影响，并预测货架期的差异。结果表明：随着储藏时间的延长，2种脱酸红花籽油的理化品质、脂质伴随物含量 ...
