Interfaces are important regarding the mechanical behavior of foods. In particle-polymer-based food systems, the rheological effect of interface characteristics between microscopic particles and viscoelastic polymers is controversial. By using a new approach of presenting defined glass beads surfaces, which imitate functional groups of starch particle surfaces, the adhesiveness and the adsorption mechanism between particle and polymeric food matrix (protein-/carbohydrate-based) can be controlled. The combination of defined particle-polymer interfaces with a comprehensive rheological analysis gives new insights into the effect of particle-polymer interfaces on the mechanical properties of food. Independent of the matrix-type, non-adhesive particles show the strongest network at low stress (protein-based: network strength A_f = 2.02 ± 0.16 ∗ 10⁴ Pas^1/z), but the fastest network breakdown under higher stress (fracture strain protein-based 4.40 ± 0.08). Adhesive particles behave inverse (A_f = 1.02 ± 0.24 *10⁴ Pas^1/z; fracture strain 5.38 ± 0.32). Consequently, particle supplemented protein-/carbohydrate-based matrices have properties similar to particle reinforced rubbers and exhibit a more or less pronounced Payne effect depending on the adhesiveness. Besides the adhesiveness, the adsorption mechanism affects the deformation behavior of particle-polymer based system. The highly adhesive but unspecific adsorption of carbohydrate-based polymers at cyano-functionalized surfaces shows a similar relaxation behavior as non-adhesive surface functionalization.

界面对于食品的机械行为很重要。在基于颗粒聚合物的食品系统中，微观颗粒和粘弹性聚合物之间界面特性的流变效应是有争议的。通过使用模拟淀粉颗粒表面官能团的定义玻璃珠表面的新方法，可以控制颗粒与聚合物食物基质（基于蛋白质/碳水化合物）之间的粘附性和吸附机制。定义的颗粒-聚合物界面与综合流变学分析相结合，为了解颗粒-聚合物界面对食品机械性能的影响提供了新的见解。独立于基质类型，非粘性颗粒在低应力下表现出最强的网络（基于蛋白质：网络强度 A _f = 2.02 ± 0.16 ∗ 10 ⁴ Pas ^1/z )，但在较高压力下最快的网络崩溃（基于断裂应变蛋白的 4.40 ± 0.08）。粘合剂颗粒的行为相反 (A _f  = 1.02 ± 0.24 *10 ⁴ Pas ^1/z; 断裂应变 5.38 ± 0.32)。因此，颗粒补充的蛋白质/碳水化合物基基质具有类似于颗粒增强橡胶的特性，并根据粘合性或多或少表现出明显的佩恩效应。除了粘附性外，吸附机制还会影响基于粒子-聚合物的系统的变形行为。基于碳水化合物的聚合物在氰基官能化表面上的高度粘性但非特异性吸附显示出与非粘性表面官能化相似的松弛行为。
