将发芽的白软冬麦及红硬冬麦剥碾去除一部分富含α—淀粉酶的外部组织和胚端,然后经过特殊润麦(加水1％,保持5分钟),制成面粉。白软麦在[发芽:未发芽为20:80]剥碾除重11％时,统粉出率为66.1％。该统粉与不经剥碾而常规加工的面粉比较,α—淀粉酶活性降低约70％,蛋糕体积增加约250毫升/100克粉。发芽的红硬麦以这种工艺加工所得的面粉,α—淀粉酶活性也明显下降。面包心Amylograph粘度计峰值增高,表明减轻了α—淀粉酶活性过高所造成的而包心发粘。

小麦剖流制粉技术(splitmilling),是将小麦研磨系统各道产出的不同粉流混合组配加工成多种面粉成品的制粉技术。这种制粉技术,对于生产原料只有一种小麦,而销售市场又存在多样专用粉需求的面粉厂,尤其具有实际应用价值。在中试制粉厂,进行了硬质红皮冬小麦的制粉试验。加工制得23种粉流,分析了每种粉流的物理和化学特性,以及面团流变特性。所有的粉流,按照适用生产面包、通心面条、蛋糕和饼干等各类食品特定要求的不同基料混合粉之常用性质,分流混合,组配成4类基质混合粉。随后,依据生产面包、通心面条、蛋糕和饼干的相应特性要求,试验4类基质混合粉各自不同的配比组合。测试各项的检测结果,运用响应面法(responsesurfacemethod)分析,并确定适用同时生产每种专用粉的最佳配比组合。最终的配比组合结果是,同时生产面包、通心面条、蛋糕和饼干4类专用粉,它们各自占产出全部面粉的百分率,分别为53.98%、23.02%、8.02%和14.98%。优化组配制得的这些专用粉,对照比较相应的商品面粉,验证了本项研究结果。

For the dynamics of three-dimensional electron–positron–ion plasmas, a fluid quantum hydrodynamic model is proposed by considering Landau quantization effects in dense ***–neutral collisions in the presence of the Coriolis force are also considered. The application of the reductive perturbation technique produces a wave evolution equation represented by a damped Korteweg–de Vries equation. This equation, however, is insufficient for describing waves in our system at very low dispersion coefficients. As a result, we considered the highest-order perturbation, which resulted in the damped Kawahara equation. The effects of the magnetic field, Landau quantization, the ratio of positron density to electron density, the ratio of positron density to ion density, and the direction cosine on linear dispersion laws as well as soliton and conoidal solutions of the damped Kawahara equation are explored. The understanding from this research can contribute to the broader field of astrophysics and aid in the interpretation of observational data from white dwarfs.

early-life stress(eLs)refers to a period of environmental/social deprivation,physica l,sexual or emotional abuse,neglect,severe and/or chronic trauma in the prenatal/early postnatal stage,which is closely related to many adverse psychiatric disorders later in life,such as depressive disorder,substance abuse,dysthymia,panic,anxiety,and suicidal behavior in adulthood(Waters and Gould,2022).
