Quality evaluation of cultured meat with plant protein scaffold

Cultured meat technology is a promising new technology to solve the negative problems brought by traditional animal husbandry. Cultured meat should be further developed to appear on consumers' tables as alternative protein product. Therefore, this study used food grade peanut wire-drawing protein as scaffold to culture smooth muscle cells (SMCs) in vitro to obtain cultured meat productions containing both animal protein and plant protein. Multiple passages lead to the decline of the proliferation rate of SMCs in the proliferation stage and the differentiation ability in the differentiation stage, which means that the plasticity of cells decreased in the later stage of passage. SMCs can well adhere to the peanut wire-drawing protein scaffold and produce extracellular matrix protein and muscle protein, so as to form a cultured meat product with rich protein composition. This study provides a theoretical basis for the production of nutrient-rich cultured meat products.
