The application provides an application of an algal composition in
plant protein meat and belongs to the technical field of
food processing; the
carotenoid content in the
plant protein meat can be regulated, and a preparation method comprises the following steps: mixing
algal cells and a tissue
scaffold matrix to obtain a bio-ink, performing 3D printing to obtain an algal composition, cross-linking by using a cross-linking agent, and performing high-density culture and
stress induction culture after forming a hydrogel. In the application, microalgae are used as a sustainable
nutrient source and an endogenous colorant, and the application first realizes the regulation of microalgae-derived pigments in
cultured meat, establishes a low-carbon and reasonable research framework for future food
system design customization and obtaining of health-promoting
cultured meat products.
