This eliminates the ethical concerns, environmental impacts, and resource consumption associated with traditional meat production. Cell-cultured meat is a relatively new technology, but its potential is immense. It has already garnered significant interest and investment from investors and researchers alike.
The production of meat, particularly beef, is a significant contributor to environmental degradation. The environmental impact of meat production is multifaceted, encompassing issues like greenhouse gas emissions, deforestation, water pollution, and biodiversity loss. However, cell-based meat production offers a promising alternative to traditional meat production.
Pre-culture: This stage involves the isolation and expansion of animal stem cells. Culture: This stage involves the growth of the cells in a bioreactor, where they are provided with nutrients and oxygen. Differentiation: This stage involves the formation of muscle tissue from the cultured cells. Harvesting: This stage involves the extraction of the meat from the bioreactor.
Cultivate and proliferate the isolated cells in bioreactors filled with a nutrient-rich culture medium, rapidly increasing the cell count Phase 3: Tissue Maturation Guide the cells to differentiate into muscle, fat, and connective tissue, structuring them into three-dimensional forms that resemble natural meat Guide the cells to differentiate into muscle, fat, and connective tissue, structuring them into three-dimensional forms that resemble natural meat Phase 4: Processing into a Food Product Harvest the matured tissue, refine its texture and flavour, and prepare it for use as a meat product in food However, despite the advantages to cell-cultured meat, there are certain difficulties around its production. The major drawback is currently the cost of the manufacturing process, which has a minimum open cost far higher than farmed meat. Of this higher expense, the culture medium is the driver for this additional outlay, which makes the search for a way to lower this crucial for the long-term future of cultured meat.
* **Serum-free media:** A growing trend in cell culture, aiming to reduce reliance on animal-derived serum. * **Fetal bovine serum (FBS):** A common, but expensive, component of cell culture media. * **Cost reduction:** A key goal in cell culture, particularly for research and development. * **Alternative media:** Researchers are exploring various alternatives to FBS, including chemically defined media and serum-free media.
The use of serum-free media in cell culture presents both advantages and disadvantages. Serum-free media are becoming increasingly popular due to their potential to reduce animal-derived products and promote sustainability. However, they also pose challenges in terms of nutrient availability, cell growth and viability, and reproducibility and scalability.
With plant-based protein hydrolysate, the product can provide varying amino acid profiles depending on the plant source, allowing for a supply of essential amino acids to be delivered for protein synthesis and cell growth. This form of protein hydrolysate can also provide bioactive peptides and certain vitamins and minerals. An important factor for producers looking to manufacture cell-cultured meat at scale is the quality requirements, and the use of protein hydrolysate is suitable in this regard. The product features high solubility, low endotoxin levels, high filtration performance and high stability. These elements combine to make protein hydrolysates effective for use alongside fetal bovine serum in the cell culture medium, allowing for the partial replacement of the serum and cell growth factors. This provides an important advantage, which is the ability to reduce the overall cost of culture media, making the process more economically viable on a larger scale.
Selecting a partner to work with on the supply of protein hydrolysates is crucial because of its importance in the process for cultured meat. Angel Yeast has been working on the development of yeast biotechnology since its establishment nearly 40 years ago. Through this experience, Angel Yeast has independently developed various production processes to create a range of yeast- and plant-based protein hydrolysates with diverse nutritional characteristics. Importantly, the protein hydrolysates have been developed based on customer feedback and their specific requirements. Behind this work are numerous experiments that support Angel Yeast’s ability to provide products that are able to provide the necessary nutrients for cell growth and proliferation.
