Abstract

For cultured meat to effectively replace traditional meat, it is essential to develop scaffolds that replicate key attributes of real meat, such as taste, nutrition, flavor, and texture. However, one of the significant challenges in replicating meat characteristics with scaffolds lies in the considerable gap between the stiffness preferred by cells and the textural properties desired by humans. To address this issue, we focused on the microscale environment conducive to cell growth and the macro-scale properties favored by humans. This led to the development of the adaptive bio-orchestrating anisotropic scaffold (ABS), which satisfies both cellular and human requirements. The ABS is produced using the anisotropic freeze-initiated ion coordination method, which sequentially aligns and enhances the fibril structure of food-derived proteins, effectively bridging the gap between cellular and culinary perspectives. Notably, the microenvironments of the ABS exhibited exceptional myoblast cell differentiation, with macro-scale 3D mechanical textures that are consistent regardless of the chewing direction, due to the aligned fibril and cell structure. The ABS containing bovine myotubes demonstrated a mechanical texture nearly identical to that of beef sirloins.

摘要

为了使培养肉有效地替代传统肉类,开发能够复制真实肉类关键特性(如味道、营养、风味和质地)的支架至关重要。然而,用支架复制肉类特性的一个重大挑战在于细胞偏好的硬度与人类期望的质地特性之间存在相当大的差距。为了解决这个问题,我们专注于有利于细胞生长的微观环境和人类青睐的宏观特性。这促使了适应性生物编排各向异性支架(ABS)的开发,它满足了细胞和人类的需求。ABS是使用各向异性冷冻引发离子配位方法生产的,该方法依次排列并增强了食物来源蛋白质的纤维结构,有效地弥合了细胞和烹饪视角之间的差距。值得注意的是,ABS的微观环境表现出卓越的成肌细胞分化,由于纤维和细胞结构排列整齐,其宏观尺度的3D机械质地无论咀嚼方向如何都保持一致。含有牛肌管的ABS表现出与牛里脊几乎相同的机械质地。
