Formulated media for enhanced shelf stability in cultivated meat

Overview

Defined Bioscience introduces a pioneering approach to enhance the shelf stability of cultivated meat through innovative cell culture media formulations. By modifying the composition of the cell culture medium, this solution aims to increase antioxidant content, alter lipid composition, and boost the expression of natural antimicrobial peptides. This approach seeks to achieve room-temperature shelf stability for cultivated meat without the need for thermal sterilization or extensive post-processing, offering significant advantages in terms of storage and distribution.

Technical specifications

The core technology involves modifying cell culture media used during the production of cultivated meat. Key components of the media, such as amino acids, micronutrients, and lipid precursors, are precisely adjusted to direct bovine muscle and fat cells to produce higher levels of natural antioxidants like glutathione and carnosine, as well as antimicrobial peptides. These components are crucial in reducing oxidative rancidity and microbial susceptibility, which are primary factors affecting shelf stability. The media is defined and serum-free, allowing for precise control over cellular outputs, leading to enhanced shelf-stable traits.

Technology readiness level

The current technology readiness level is 5, indicating that the concept has been validated in a laboratory setting. The next steps involve testing media formulations in small-scale cultures to evaluate their impact on cellular metabolite output, microbial resistance, and oxidative stability. Subsequent trials will be conducted in multi-liter bioreactor runs, with the aim to test prototype meat products in various packaging formats. This progression will require collaboration and funding support to enable further development and validation.
