本文旨在研究饲粮添加桉叶多酚粗提物对于胡须鸡生长性能、抗氧化、肉质的影响,并测定肌肉各项指标,探讨桉叶多酚对于鸡肉肉品质的影响.试验选用90日龄胡须鸡324只,分为A(空白组)、B (0.6g/kg桉叶多酚组)、C (0.9g/kg桉叶多酚组)、D(1.2g/kg桉叶多酚组)、E(普通饲料)、F(0.9g/kg桉叶多酚组+普通饲料)六个实验组,每组六个重复,每个重复九只鸡,采用自由采食方式,人工喂养40d后进行采样并测定相关指标.结果表明：在130日龄时,相对于对照组,0.9g/kg桉叶多酚组对胡须鸡胸肌、腿肌GSH-PX有显著提高(p＜0.05),对胡须鸡胸肌、腿肌MDA有显著降低作用(p＜0.05),1.2g/kg桉叶多酚组对胡须鸡腿肌GSH-PX有显著提高(p＜0.05)；0.6g/kg桉叶多酚组对胡须鸡胸肌a*(红度)有显著影响(p＜0.05),0.6g/kg、0.9g/kg、 1.2g/kg桉叶多酚组对于腿肌a*(红度)均有显著影响(p ＜0.05)；0.9g/kg桉叶多酚组对胡须鸡胸肌、腿肌肌内脂肪均有显著提高(p ＜0.05)；1.2g/kg桉叶多酚组对胡须鸡胸肌氧合肌红蛋白、肌红蛋白有显著提高作用(p＜0.05),高铁肌红蛋白显著下降(p ＜0.05)；0.6g/kg桉叶多酚组对胡须鸡腿肌中氧合肌红蛋白有显著影响(p＜0.05),0.9g/kg桉叶多酚组对肌红蛋白含量也有显著影响(p＜0.05).综上所述,桉叶多酚粗提物对胡须鸡肉质改良和抗氧化有显著效果,这为桉叶多酚的进一步研究提供了科学依据.

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
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
