Italian Bioengineer Develops 3D-Printed Vegan Steak From Plant-Based Proteins (dezeen.com) 297

Italian bioengineer Giuseppe Scionti from Spanish startup Novameat has invented the "world's first" 3D-printed meat-free steak made from vegetable proteins, which mimics the texture of beef. From a report: Vegan ingredients such as rice, peas and seaweed, which provide the amino acids needed for a healthy diet, are turned into a food paste that is 3D-printed to form a raw, steak-like substance. Despite an abundance of meat-free products already on the market that taste similar to animal meats, Scionti found that these are limited to imitation burgers, chicken nuggets or meatballs. None of the offerings reproduce a piece of "fibrous flesh" such as steak or chicken breast. In an effort to reduce the impact of animal agriculture and to improve people's nutrition, the Milanese researcher set out to create a plant-based alternative to "fleshy" meat products.

      Why are vegans obsessed with making stuff that isn't meat into something they can call "meat". Surely a vegan is not interested in the appeal of something that sounds like meat, and a non vegan surely is not fooled into thinking that mushy brownish bean curd is a substitute for a nice, rare and bloody steak.

        Nope, we are not obsessed. Many vegans/vegetarians like me would not eat anything that looks like meat.

        It is the carnivores who think it is an advantage to make vegetables look and taste lime meat.

        • You spelled "omnivore" wrong.

          To the average human palate, meat tastes good. Our entire physiology is adapted to accept meat as nutrition. The ethical arguments against cruelty are the strongest vegans have, and I generally agree with them. However, a lot of animals are killed to allow our crops to grow, so that argument is not absolute. However, matching a lot of the nutritional profile to meats is useful. If you can make a vegetable based thing that actually tastes like meat, has the texture, etc., I'll ha

        While I love meat I'd be perfectly happy to eat my proteins in other ways as long as it satisfies above - whether it mimics meat or is its own thing, I'm happy either way.

        Mostly, they aren't. Many vegans aren't interested in fake meat. It is more for non-vegans that crave meat but want a healthier, greener, more humane, or whatever, option.

          And I really wonder what's the objective of vegan with that sort of research. I mean, let's say they succeed to make a lab steak that's cheap and taste the real the thing. What's gonna happen?

Environmental concerns aside, if I can eat something as delicious as that but more nutritious, lower calorie, doesn't require so much infrastructure to enforce animal welfare...

            Well they ain't cheap, I'll tell you that much.

            In the longer term it should be possible to make them very good. Plant food is much cheaper than meat to start with, so there is plenty of margin to work with. There is a market for good food too, and of course we can regulate it to ensure that manufacturers don't get silly.

            Put it this way, it can't be any worse than Turkey Twizzlers.

          • Yes, but are they nutritious and healthy ? It's a highly processed food

            Meaning what? Define processing. There are plenty of healthy processed foods. There are plenty of processed foods loaded with everything bad for you.
            What is processing? Do I need to reconstitute something? Do I need to grind down offal and sell it as meat? Do canned fruits count? They are processed. What about wine, most of that contains additive 220 so you can consider that "processed" too for a certain definition.

            I hate hearing the term "processed food".

          Can you name some brands to consider trying? And maybe what you're comparing them to? I have some vegan friends and every attempt at a dinner party has often resulted in something that compares favourably only to a Mcdonalds meat patty and to be honest I'm not sure there's any meat in that either.

      No, it's but everything being made in it's entirety from a robot controlled extruded is pretty much going to be labeled "3d printed". The correct term is additive manufacturing. Feel free to flip a table or two because it's not going away.

      I know this is slashdot, but that's an absurd rant. The machine in the article looks very similar to the 3d printer on my desk. It just extrudes a different material to the plastic mine extrudes. Why the problem with the term 3d printed ? It's a perfectly useful term with a clear meaning, which in my view is used quite suitably in this context. Some here say the "correct" term is additive manufacturing - well I'd say that's just an alternative term. There's nothing incorrect about calling something 3d printing if it's coming from a machine that extrudes a material to create three dimensional objects layer by layer. And it's not a hype. It's an extremely useful technology that is now becoming cheap enough to be available domestically. It's like calling smartphones a hype ten years ago. Or the internet. Is that a hype ? I genuinely believe that all of these new and innovative applications of 3d printing, particularly with new kinds of materials, like in this article, are examples of they way manufacturing is being turned on its head. Extraordinary things are happening, and I for one am really interested in reading about them.

      The problem with faux meat is replicating the structure and the fat distribution. Textured protein does an okay job at the filamentous part, but can't distribute fat through the produced chunks. Also the chunks are limited in size.

      With fused deposition modeling (ie. 3d printing) you can replicate that structure to some extent and distribute fat throughout, in far larger chunks than can be produced by textured protein extrusion.

    • by AmiMoJo ( 196126 )

      The "printed" part refers to arranging the extruded material in a specific pattern under computer numerical control (CNC). As opposed you the uncontrolled shape of toothpaste that you extrude by hand.

      This has in fact been around for a while in the food industry, e.g. confections with CNC printed decorations.

    2) No information on it's taste or consistency. Being translucent is not a good sign.
