摘要： 测定了我国17个不同来源DDGS(A～Q)的色泽(L^*、a^*和b^*值)、容重、水溶物含量和常规营养成分及10个DDGS(A、C、D、E、F、G、H、L、O和Q)的AFB1和三聚氰胺含量。结果表明:A～Q的L^*、a^*和b^*值范围分别为33.32～44.34、6.08～10.43和7.45～15.42,容重范围为345～545 g/L,水溶物平均含量为26.17%,总能、粗蛋白、粗脂肪、NDF、ADF、钙、总磷和非植酸磷平均含量分别为19.07 MJ/kg,27.85%,9.06%,42.20%,12.81%,0.07%,0.64%和0.56%。同一厂家不同批次的DDGS(A和B,C和D,H和I)的L*值、b*值、容重、水溶物含量、总能、干物质、粗蛋白、粗脂肪、NDF、ADF、钙、总磷、非植酸磷含量的变异系数都低于17个不同来源的DDGS(A～Q)。湿法生产DDGS(A、B、C、D和F)和非玉米DDGS(P和Q)的粗脂肪含量低于6%。DDGS的水溶物含量与总磷和非植酸磷含量呈中等程度相关。DDGS的AFB₁含量范围为2.33～22.45μg/kg,三聚氰胺未检出。本研究表明,不同原料和加工工艺的DDGS物理性状和营养成分变异性大,本试验检测的10个DDGS应用于动物生产中是安全的。

Abstract: We anlysed the color(L^*,a^* and b^*),bulk density,water solubles matter and conventional nutritive components of 17 DDGS(A-Q) from different sources in China,and determined the AFB1 and melamine in 10 DDGS(A,B,C,E,F,G,H,L,O and Q) among them.Results:About the color of these DDGS,L^* rang from 33.32 to 44.34,a^* rang from 6.08 to 10.43,b^* rang from 7.45 to 15.42,respecctively.The bulk density rang from 345 to 545 g/L.The average water solubles matter is 26.17%.The average content of GE,CP,EE,NDF,ADF,Ca,total phophorus(TP) and non-phytate(NPP) are 19.07 MJ/kg,27.85%,9.06%,42.20%,12.81%,0.07%,0.64% and 0.56% respectively.The variation in color(L^*,b^*),bulk density,water solubles matter,GE,DM,CP,EE,NDF,Ca,TP,NPP within plants(A and B,C and D,H and I) lower than between different plants(A-Q).The EE content of A,B,C,D,F,P and Q is less than 6%.The DDGS water solubles matter positive correlated with TP and NPP.The DDGS AFB1 is 2.33~22.45 μg/kg and the melamine was not detected by High Performance Liquid Chromatography in the DDGS.There is higher variability in physical properties and nutrient level of DDGS from different raw material and different raw material The 10 DDGS in this experiment are safety for feedstuffs.
