茶多酚在獭兔肉保鲜中抗氧化效果初步研究(7000字)
摘 要:本文主要研究了茶多酚在獭兔肉保鲜中抗氧化效果。将不同浓度的茶多酚(0.25%、0.50%、1.00%、1.5%、2.00%)应用到獭兔肉中,通过测定其理化指标,并且进行感官评定来判定茶多酚对獭兔肉的保鲜作用及抗氧化能力。结果表明,茶多酚浓度为2.00%时,对獭兔肉有较好的保鲜效果,且对獭兔肉的颜色影响不大,同时表现出较强的抗氧化能力。

Preliminary Study on the Anti-oxidation Effects of Tea Polyphenol to Fresh Rabbit Meat
Abstract: In order to determine the antioxidation effect, different concentration of tea polyphenols(0.25%、0.50%、1.00%、1.5%、2.00%)were added to fresh rabbit meat.by analyzing its physic-chemical properties changes and also organoleptic evaluation. Study showed that treatment of2.00%tea polyphenols was the most efficient in terms of fresh keeping and antioxidation capacity; and had little negative impact to the color to fresh rabbit meat.

本实验将不同浓度的茶多酚应用于獭兔肉中,通过测定其表征脂肪氧化酸败程度的硫代巴比妥酸反应物质(Thiobarbituric Acid-Reactive Substances,TBARS)、挥发性盐基氮(TVB-N值)、肉中的pH值以及VE与茶多酚抗氧化性能的比较(单因子试验和复合试验)和感官指标,从而研究茶多酚对獭兔肉保鲜及其抗氧化能力的影响。
