The release of aldehydes from aqueous model systems containing starch or maltodextrins with different dextrose‐equivalent (DE) values was evaluated using static headspace analysis. The patterns of aldehydes released differed significantly between starch and maltodextrin solutions with DE values of 4.0–7.0, 13.0–17.0, and 16.5–19.5. The release of most of aldehydes showed an increasing tendency according to DE values of maltodextrins. The release of most aldehydes decreased up to around 24 h, but then increased slightly at 48 h. In addition, the absorbance values of iodine‐polysaccharide complexes and the particle sizes of the polysaccharides were measured to investigate the effects of hydrophobic regions and the intermolecular aggregation of polysaccharides on the releases of aldehydes. The absorbance values of iodine‐polysaccharide complexes, which could be related to the internal hydrophobic regions, decreased in the maltodextrin and starch solutions as the equilibrium time increased up to 24 h, but then increased at 48 h. Also, the particle size increased gradually to 48 h, suggesting that the intermolecular aggregation of polysaccharides affects the release of aldehydes.

不同葡萄糖当量值的麦芽糊精的影响

使用静态顶空分析评估了含有淀粉或麦芽糖糊精的水性模型系统中醛的释放量，这些淀粉或麦芽糊精的葡萄糖当量（DE）值不同。淀粉和麦芽糊精溶液之间释放的醛的模式差异很大，DE值分别为4.0-7.0、13.0-17.0和16.5-19.5。根据麦芽糖糊精的DE值，大多数醛的释放显示出增加的趋势。大部分醛的释放减少至约24小时，但随后在48小时略有增加。此外，还测量了碘-多糖复合物的吸光度值和多糖的粒径，以研究疏水区和多糖的分子间聚集对醛释放的影响。碘多糖复合物的吸光度值 这可能与内部疏水区域有关，麦芽糖糊精和淀粉溶液中的平衡时间随着平衡时间的增加而增加，直到24小时，然后在48小时时增加。同样，粒径逐渐增加至48小时，表明多糖的分子间聚集会影响醛的释放。
