基于GC-IMS技术分析湿提和热榨 油茶籽油风味的差异Flavor difference between wet extracted and hot-pressed oil-tea camellia seed oils based on GC-IMS

Zhongguo youzhi, 2023
为探究不同工艺对油茶籽油风味的影响，采用气相色谱-离子迁移谱（GC-IMS）技术对湿提和热榨油茶籽油风味物质进行分析。结果表明：湿提和热榨油茶籽油中均鉴定出32种风味物质；醛类是湿提和热榨油茶籽油主要的风味成分，其在湿提和热榨油茶籽油含量分别为62.62%和70.52%；湿提和热榨油茶籽油风味成分差异主要在于醛类和醇类物质含量，湿提油茶籽油的醇类和酯类物质含量高于热榨油茶籽油，糠醛含量（1.96%）远低于热榨茶籽油（11.18%）；通过主成分分析和样品间相似度分析比较，两种工艺油茶籽油整体风味差异明显 ...

基于质量标准的油茶籽油和橄榄油比较分析Comparison of oil-tea camellia seed oil and olive oil based on quality standards

Zhongguo youzhi, 2022
基于质量标准对油茶籽油和橄榄油进行比较分析。结果表明：油茶籽油与橄榄油的特征指标和质量指标相似，油茶籽油具有碘值低、抗氧化能力强、稳定性好、烟点高等特性；油茶籽油与橄榄油中不饱和脂肪酸含量均高，油酸均是最主要的脂肪酸，油茶籽油中油酸含量甚至比橄榄油的高；油茶籽油中饱和脂肪酸含量约10%，比橄榄油的低；油茶籽油中含有多酚、黄酮等活性营养成分，营养价值高。另外，指出了现行油茶质量标准体系亟待完善的问题，为油茶籽油的深度开发利用提供参考。 The oil-tea camellia seed oil and ...

基于挥发性成分定性判别风味油茶籽油掺伪浸出 油茶籽油PCA模型和逻辑回归模型的对比分析 Comparative analysis between PCA model and logistic regression model for qualitative identification of flavor oil-tea camellia seed oil adulteration with leaching oil-tea camellia seed oil based on volatile components

Zhongguo youzhi, 2023
为了解决风味（原香和烤香）油茶籽油掺伪浸出油茶籽油的定性判别问题，设计高、低两个掺伪梯度，基于挥发性成分构建并对比分析了定性判别风味油茶籽油掺伪浸出油茶籽油的主成分分析（PCA）模型和逻辑回归模型。结果表明：逻辑回归模型定性判别风味油茶籽油掺伪浸出油茶籽油的能力较强，优于PCA模型；高掺伪梯度下定性判别原香和烤香油茶籽油掺伪浸出油茶籽油，PCA模型的最低检出限分别为20%和60%，而逻辑回归模型的最低检出限均为10%；低掺伪梯度下定性判别原香和烤香油茶籽油掺伪浸出油茶籽油，PCA模型的判别不准确 ...
