摘　　要：狗咬胶是一种具有口腔清洁作用的宠物护理零食,通过体外模拟与动物试验考察茶叶与茶多酚狗咬胶对犬口腔除臭与牙齿护理方面的功效。通过体外模拟清除异味试验测定乌龙茶、红茶、普洱茶对硫化氢气体的清除效果,结果显示乌龙茶的除臭效果较佳。采用乌龙茶质量分数为0.5%~2.0%、茶多酚质量分数为0.25%~0.75%的狗咬胶产品进行为期3周的动物试验,结果表明,随着有效物质质量分数的增加,犬口腔内的硫化氢气体清除率不断上升,当乌龙茶质量分数为2.0%或茶多酚质量分数为0.75%时,犬口腔内硫化氢气体清除率接近100%,且牙垢清除率显著提高,达到60%以上。总酚质量分数与口腔改善效果的拟合分析表明,随着总酚质量分数的增加,犬口腔内的硫化氢气体清除率、牙垢清除率均得到提高,且总酚质量分数与硫化氢气体清除率和牙垢清除率具备较强的正相关性,从而证明了茶叶与茶多酚狗咬胶在犬口腔护理方面的积极作用。Dog chews is a kind of snack for pet with oral cleaning effects.This research studied the effect of adding tea or tea polyphenols in dog chews on oral deodorization and dental care using in vitro simulation and animal experiments.The effect of Oolong tea,black tea and Pu'er tea on removing hydrogen sulfide was determined in vitro,which showed that Oolong tea had the best deodorization efficiency.The dog chews with the Oolong tea mass fraction of 0.5%~2.0%and tea polyphenols of 0.25%~0.75%were tested on dogs for 3 weeks.The results showed that the elimination rate of hydrogen sulfide in the oral of experimental dogs increased with the increase of the added effective substances.As the amount of Oolong tea was 2.0%or the mass fraction of tea polyphenols was 0.75%,the elimination rate of hydrogen sulfide in the oral cavity was close to 100%,and the tartar reduction rate was significantly increased to more than 60%.Fits of the total phenolics mass fraction and the effects showed that the elimination rate of hydrogen sulfide and the reduction rate of tartar both increased with the increasing of total phenolics mass fraction.Notably,there was a strong correlation between the total phenolics mass fraction and the elimination rate of hydrogen sulfide and the reduction rate of tartar.This study demonstrated the positive effect of polyphenols dog chews on dog oral health.
