\"2015-11-25<\/a>I heard an article on the news about grass fed artificial meat this morning.\u00a0 This was from a group from a University in the South of England trying a new approach.\u00a0 The\u00a0artificial meat cells were grass fed but in culture.\u00a0 The big problem with experiments in growing meat in culture up until now is the problem over the protein source.\u00a0 All cells need a protein source or at least a source of amino-acids.\u00a0 What normally happens is that any proteins provided are then broken down to their constituent amino-acids.\u00a0 These are then used to make new proteins by the cells.\u00a0 Having worked in animal cell lines I personally don\u2019t fancy eating cells grown on animal serum. The issue is two fold. The cells still require the use of animals to grow animal serum.\u00a0 This to me defeats the purpose.\u00a0 The second problem is the viruses that might be present in the serum. This is to be fair is a potential problem in many vaccines, where the viruses are cultured in mammalian cell lines.\u00a0 It doesn\u2019t seem to be problem with vaccines since hundreds of millions of people are vaccinated every year without a problem. However, there is a difference between the way vaccines are produced and cultured meat cell would be produced.\u00a0 Vaccines are freeze dried before use.\u00a0 That is the vaccine material is cooled under a vacuum, then the vials are sealed aseptically.\u00a0 This promotes \u201cviral kill\u201d, (although technically viruses aren\u2019t alive). The reader will be aware that every time you\u2019re vaccinated the nurse or doctor has to reconstitute the lyophilsed material with sterile water. As part of the development of the vaccine, virus models are used to determine that the virues have been removed.\u00a0 I\u2019ve been involved in some of this work in the past. The point is meat grown in culture will not be freeze dried, but merely recovered and processed in some way. The alternative is to use serum free media.\u00a0 In this amino-acids are added individually not formed as proteins.<\/p>\n

The work described on the radio was merely changing the carbon source of the cells grown as artificial meat.\u00a0 All cells require this as well as amino-acids and vitamins\/minerals.\u00a0 The researchers are not literally adding grass but breaking the grass down to glucose.\u00a0 Does this really help though?\u00a0 The grass has to come from somewhere? So do the proteins or amino-acids.\u00a0 The people concerned reckoned their\u00a0artificial meat had carbon emissions are less than a cow in a field. But really supplying all the nutrients etc. takes energy.\u00a0 Its a little bit to believe any industrial process is more efficient than an animal in a field.<\/p>\n
