犬牙齿保健日粮配方及加工工艺的优化研究

本试验为了优化牙齿保健处方犬日粮配方和加工工艺，采用三因素(小麦面筋、明胶、甘油)正交试验设计，筛选出小麦面筋、明胶、甘油最佳添加比例。研究结果表明,小麦面筋添加比例越低，硬度相对较高；甘油比例提高，硬度和表观状态也相应地提高；明胶比例越高，硬度越大，韧性越好。筛选出牙齿保健处方犬日粮的最佳配方为小麦面筋35％、明胶6％、甘油15％、去离子水15％、膨化玉米粉27％、乳化剂0.5％、其它微量成分1.5％。根据饲料原料的性质探索出处方犬日粮的适合加工工艺为将小麦面筋、玉米粉、乳化剂、淀粉在干物质状态下混合均匀，将明胶与甘油混合均匀，然后将两者混在一起搅匀，加入适量水后揉成面饼，放在恒温箱中于72 ℃烘烤6 h。

Research on Optimization of the Formula and Processing of Dog Dietary for Teeth Care

The experiment was conducted to optimize the formula and processing of dog dietary for teeth care.The experiment was adopted orthogonal experimental design with three factors(wheat gluten,gel,glycerol).It could be concluded that hardness of dietary varied with the proportions of wheat gluten;the supplement of glycerol could influence hardness and the appearance of dietary;supplements of gel could influence hardness and toughness of dietary.The formula of dogs dietary was made up of 35% wheat gluten,6%gelati...
