臭氧处理对新收获小麦品质的影响

为了探讨臭氧处理应用于加速新收获小麦后熟的可行性,在室温、臭氧处理质量浓度为5mg/L、处理时间0.5~2.0h条件下分别处理新收获小麦,研究臭氧处理对新收获小麦基本成分、破损淀粉含量、湿面筋含量、面团流变学特性的影响。结果表明,与未处理组相比,臭氧处理对新收获小麦的粗蛋白含量无显著影响(P0.05),但对粗淀粉含量、破损淀粉含量、湿面筋含量、面团流变学特性有显著性影响(P0.05)。

Effects of ozone treatment on quality of newly harvested wheat

To investigate the feasibility of ozone treatment applied to accelerate post-maturation of newly harvested wheat, after treating the newly harvested wheat under the condition of room temperature, ozone concentration 5 mg/L, and ozone treatment time 0.5-2.0 h, the proximate composition, damaged starch contents, wet gluten contents, and dough rheological properties of newly harvested wheat were studied. The results showed that the group with ozone treatment had no significant effect on crude protein contents compared with the untreated wheat （P 〉0.05）, but had significant ef- fect on crude starch contents, damaged starch contents, wet gluten contents, and dough rheological properties （P〈0.05）.
