  以广佛手为材料,选择新鲜佛手、半腌制佛手、腌制佛手,测定其基本营养成分,包括水分、蛋白质、脂肪、总可溶性糖、淀粉、酸度、灰分、Vc含量、外观色泽,并分析基本营养成分在腌制过程中的变化。结果表明,随着腌制时间的延长,佛手果水分含量、蛋白质含量降低,脂肪有降低趋势,可溶性糖、总酸度升高,维生素C含量降低,淀粉、灰分含量没有明显变化,外观颜色逐渐加深(青绿色—暗黄色—黑褐色)。对三种佛手果材料的活性成分测定,分析在腌制过程中佛手活性成分的变化。佛手的主要活性成分有:多糖、黄酮、多酚。结果表明,无论是新鲜佛手还是腌制佛手,含量最多的活性成分都是多糖,在新鲜佛手中多酚含量高于黄酮,在腌制佛手中黄酮含量高于多酚。另外,随着腌制时间增长,佛手多糖含量没有显著变化,多酚和总黄酮含量降低。

该试验旨在研究蒸汽爆破处理对小麦麸皮的酚酸组成及抗氧化活性的影响.将麦麸在不同处理压力(0.5MPa, 1.5 MPa, 2.5 MPa)和不同处理时间(30 s, 90 s)条件下进行蒸汽爆破预处理. 结果表明,蒸汽爆破处理能够提高麦麸提取物中的酚酸含量,其中,阿魏酸在蒸汽爆破处理后其含量从57.232变为1049.444μg/g,有明显的上升.与未进行蒸汽爆破预处理的麦麸相比,实验组表现出了更
