Analysis The Production Technology, Research Progress and Future Direction of Cell Culture Meat

As one of the "Top Ten Emerging Technologies" released by the World Economic Forum in 2018 and one of the "Ten Breakthrough Technologies" selected by the MIT Technology Review in 2019, cell-cultured meat is considered to be the most likely solution to the future of human meat. One of the scenarios of the production and consumption dilemma. Cell culture meat is a new type of meat food produced by large-scale in vitro culture of animal cells and tissues in sterile laboratories or factories by using advanced technologies in the fields of cell biology, tissue engineering and food engineering.

The production process of cell-cultured meat is as follows: first, stem cells with self-renewal and multi-directional differentiation potential are isolated from animal biopsy tissues, and then they are massively expanded and induced to differentiate to generate muscle fibers, fat or other cell types, and then assembled, food-based processes such as shaping, coloring and seasoning produce nutritious and delicious meat products. However, the cell-cultured meat industry is currently in its infancy. Researchers are conducting research on optimizing the cell culture system, exploring the best scale-up process, and reducing production costs, in order to speed up the industrialization and commercialization of cell-cultured meat.

The so-called artificial meat can be divided into plant protein meat and cell culture meat. Among them, vegetable protein meat has gradually begun to be commercialized, and cell culture meat is cultivated with animal cells, which is closer to real meat products. From the perspective of bioethics, the research and development and production of cell culture meat can help ensure the sustainable development of human society, improve animal welfare, reduce resource demand, improve the nutritional function of meat products, and provide new growth points for the development of other industries. In addition, in-depth consideration was given to the ethical risks involved in the production of cell-cultured meat in terms of food safety, technology abuse, and technical regulation, hoping to provide a reference for the sustainable development of the artificial meat industry from the perspective of bioethics.

Food is essential to human survival, and a balanced diet is critical to people's health and well-being. With the development of society and technology, people's food consumption concept has undergone tremendous changes, and the demand for food has shifted from basic "guaranteed supply" to "nutrition and health". In addition, with the aggravation of environmental pollution and the increase of world population, there is an urgent need to adopt new technology to meet people's higher demand for food, while also ensuring food safety, nutritional value and sustainability.

With the development of synthetic biology, the food industry is undergoing tremendous changes. The effective combination of food science and synthetic biology is not only an important technology to solve the problems of food safety and nutrition, but also an important means to overcome the unsustainable problems brought about by traditional food technology. Synthetic biology allows for improved food production through the use of programmed monoclonal cell factories, engineered microbial consortia, or cell-free biosynthesis platforms.

The manufacture of cell-cultured meat, while promoting the sustainable development of human society, will also have a huge impact on the traditional animal farming industry. With the development of synthetic biology, more and more animal products can be synthesized and replaced by other methods. For example, polymer materials produced by chemical methods can replace animal leather, and pharmaceutical proteins and steroids produced by fermentation methods can replace traditional Relying on the extraction of animals will drive the rapid development of new technology industries and greatly reduce the employment problems caused by the replacement of traditional animal breeding and animal products.

Faced with the ever-changing technological innovations, people will inevitably be dazzled and at a loss, but human beings need not be overly sensitive to any progress in technology. Facing the continuous growth of the world's population base and deep environmental pollution, under the multi-dimensional analysis framework of bioethics, cell culture meat reflects the active exploration of human beings on how to adapt and integrate with the natural environment under the artificial environment and brave attempts, its proper use will definitely add an important touch to the progress and development of the entire human society, and will be extremely beneficial to the survival and development of the community of shared future for mankind.
