Abstract

Cultured meat is emerging as a new type of food that can provide animal protein in a sustainable way. Many previous studies employed various types of scaffolds to develop cultured meat with similar properties to slaughtered meat. However, important properties such as flavor were not discussed, even though they determine the quality of food. Flavor characteristics vary dramatically depending on the amount and types of amino acids and sugars that produce volatile compounds through the Maillard reaction upon cooking. In this study, a flavor-switchable scaffold is developed to release meaty flavor compounds only upon cooking temperature mimicking the Maillard reaction of slaughtered meat. By introducing a switchable flavor compound (SFC) into a gelatin-based hydrogel, we fabricate a functional scaffold that can enhance the aromatic properties of cultured meat. The temperature-responsive SFC stably remains in the scaffold during the cell culture period and can be released at the cooking temperature. Surprisingly, cultured meat fabricated with this flavor-switchable scaffold exhibits a flavor pattern similar to that of beef. This research suggests a strategy to develop cultured meat with enhanced sensorial characteristics by developing a functional scaffold which can mimic the natural cooking flavors of conventional meat.

摘要

培养肉作为一种新型食物正在兴起,它可以以可持续的方式提供动物蛋白。许多之前的研究都采用了各种类型的支架来开发具有类似于屠宰肉的特性的培养肉。然而,尽管它们决定了食物的质量,但重要的特性,如味道,并没有被讨论。味道特征因烹饪时通过美拉德反应产生挥发性化合物的氨基酸和糖的数量和类型而有很大差异。在这项研究中,开发了一种可切换味道的支架,只有在模拟屠宰肉美拉德反应的烹饪温度下才会释放肉味化合物。通过将一种可切换的风味化合物(SFC)引入到基于明胶的水凝胶中,我们制造了一种功能性支架,可增强培养肉的芳香特性。温度响应性 SFC 在细胞培养期间稳定地保留在支架中,并可以在烹饪温度下释放。令人惊讶的是,用这种味道可切换支架制造的培养肉表现出类似于牛肉的味道模式。这项研究通过开发一种可以模拟传统肉类天然烹饪风味的功能性支架,提出了一种增强培养肉感官特性的策略。
