A study was conducted to determine the chemical composition of banana meal and rice bran from Australia or South-East Asia and test the hypothesis that there are no differences in rice bran produced in different countries, but there are differences between full-fat and defatted rice bran.
Two sources of banana meal and 22 sources of rice bran (full-fat or defatted) from Australia or South-East Asia were used. All samples were analyzed for dry matter, gross energy, nitrogen, amino acids (AA), acid hydrolyzed ether extract (AEE), ash, minerals, total starch, insoluble dietary fiber, and soluble dietary fiber. Banana meal was also analyzed for sugars including glucose, fructose, maltose, sucrose, stachyose, and raffinose.
Chemical analysis demonstrated that banana meal from the Philippines is primarily composed of starch. Full-fat rice bran from Australia had greater (p<0.05) concentrations of AEE, lysine, and glycine than samples from the Philippines and Vietnam. Full-fat rice bran from Australia and Thailand had greater (p<0.05) concentrations of gross energy and most AA than rice bran from Vietnam. Full-fat rice bran from Australia had greater (p<0.05) concentrations of tryptophan and manganese than all other sources, but full-fat rice bran from the Philippines contained less (p<0.05) zinc than all other sources of rice bran. Gross energy, AEE, and copper were greater (p<0.05) in full-fat rice bran compared with defatted rice bran, but defatted rice bran contained more (p<0.05) crude protein, ash, insoluble dietary fiber, total dietary fiber, AA, and some minerals than full-fat rice bran.
Banana meal is a high-energy source that can be used as an alternative ingredient in livestock diets. Full-fat rice bran from Australia and Thailand contained more concentrations of AEE and AA than samples from the Philippines or Vietnam. Full-fat rice bran had more gross energy and AEE than defatted rice bran, whereas defatted rice bran contained more crude protein, ash, and total dietary fiber.
开展一项研究以确定来自澳大利亚或东南亚的香蕉粉和米糠的化学成分，并检验以下假设：不同国家生产的米糠没有差异，但全脂米糠和脱脂米糠之间存在差异。
使用了两种来源的香蕉粉以及来自澳大利亚或东南亚的22种米糠（全脂或脱脂）。对所有样品分析了干物质、总能、氮、氨基酸（AA）、酸水解乙醚提取物（AEE）、灰分、矿物质、总淀粉、不溶性膳食纤维和可溶性膳食纤维。还对香蕉粉分析了包括葡萄糖、果糖、麦芽糖、蔗糖、水苏糖和棉子糖在内的糖类。
化学分析表明，来自菲律宾的香蕉粉主要由淀粉组成。来自澳大利亚的全脂米糠的AEE、赖氨酸和甘氨酸浓度高于来自菲律宾和越南的样品（p<0.05）。来自澳大利亚和泰国的全脂米糠的总能和大多数氨基酸浓度高于来自越南的米糠（p<0.05）。来自澳大利亚的全脂米糠的色氨酸和锰浓度高于所有其他来源，但来自菲律宾的全脂米糠的锌含量低于所有其他米糠来源（p<0.05）。与脱脂米糠相比，全脂米糠的总能、AEE和铜含量更高（p<0.05），但脱脂米糠的粗蛋白、灰分、不溶性膳食纤维、总膳食纤维、氨基酸和一些矿物质含量比全脂米糠更多（p<0.05）。
香蕉粉是一种高能量来源，可作为家畜日粮中的替代成分。来自澳大利亚和泰国的全脂米糠的AEE和氨基酸浓度高于来自菲律宾或越南的样品。全脂米糠的总能和AEE比脱脂米糠更多，而脱脂米糠含有更多的粗蛋白、灰分和总膳食纤维。
