First Lab-Grown Eel Meat Revealed (theguardian.com) 95

An anonymous reader quotes a report from The Guardian: The first lab-grown freshwater eel meat has been produced, potentially solving a diner's dilemma. Rampant overfishing has caused eel populations to plummet and prices to soar, but the cultivated eel could provide the delicacy guilt-free. The eel meat was produced by Forsea Foods in Israel from embryonic cells of a freshwater eel. The company collaborated with a Japanese chef to create unagi kabayaki, marinated grilled eel over rice, and unagi nigiri, a type of sushi. The company aims to scale up its operation and have the cultivated eel on sale in about two years. Japan's prime minister, Fumio Kishida, last year backed the development of a cultivated meat industry. The restaurant price in Japan is about $250 a kilogram, and Forsea Foods expects the price of the cultivated eel to match that of the wild-caught eel. [...] Forsea Foods' strategy is to target species at risk of extinction in the wild that also command high prices in restaurants and shops, with eel meeting both criteria. The very complex life cycle of eels, involving long migrations from rivers to the ocean and several distinct life stages, means it is not possible to farm them like some fish. The cultivated eel was produced using organoids, tiny bundles of tissue originally developed for use in medical research. The organoids are made of embryonic stem cells taken from fertilized eel eggs. These cells can develop into any kind of tissue and, as they grow, they self-organize into the structure of real meat. The final product also contains some plant-based ingredients. Other approaches to cultivated meat require greater use of expensive growth factor chemicals and scaffolds for cells to grow on [...]. The technique is particularly suited to fish and seafood, whose meat is fairly uniform unlike, for example, marbled beef, he said. Like other cultivated meat, the product is not produced using antibiotics or hormones. Forsea Foods is the only company known to be producing cultivated meat using this technology. The company has raised $5.2 million in investment, with more expected to be announced soon.

I well never eat lab-grown meat of any kind because it will all probably taste like an eel!

Oh, wait...

Can't beat the lower environmental impact, the reduction in need to protect against contamination by disease or illness, the fact it can be done in cities instead of requiring vast tracts of land, etc. Then add in some bonus genetic modification to make it healthier for you.

Animal welfare issues are a distant concern compared to the economic ones, but those are resolved too.

Re:

It's not just the future, it's already here. They call it "hot dogs." I mean, what else could explain the taste and texture of those "tube steaks"?

Re:

You can't even buy generic cola that tastes exactly like Coke, and that's entirely man-made to begin with. While there certainly is room in the marketplace for lab grown meat, it will never taste exactly like the real thing. Besides, even among the real stuff there's significant variation in quality; I'm not even sure how this stuff [walmart.com] passes as suitable for human consumption, and that's ostensibly from the same animal as filet mignon.

    • Re:

      Trademarks only prevent you from calling your competing beverage "Coke", you're still completely free to make it taste exactly the same, if you can.

      • Re:

        You are right but coke isn't patented, if it was it would be reproducible by now. However on the point of has anybody come close to reproducing the flavor of coke you are wrong. Its close enough at least.

        From here https://daily.jstor.org/the-co... [jstor.org]

        There where 2 studies:

        The reason we think its different is marketing. It happens other places too like for water put it in a fancy bottle, and people swear it tastes better, even if its from the same hose.

        Its probably why new coke failed, not because it tastes wors

  • Re:

    I think if most people tried really good ve*an food they wouldn't miss meat at all.
      • Re:

        You mean omnivores?

        Humans have claws?

        Humans have a "hunting instinct"? Like, most humans freak out if a mouse walks past them.

        Are you sure that when you write "people" you don't actually mean "cats"?

        Hunter-gather societies around the world have widely varied ratios of animal vs plant calories, but in most, plant-based calories dominate, often dramatically. There are hunter-gatherer societies where ~90% of calories are sago (beaten palm-trunk starch) alone. And most of the "meat" is things like sago grubs.

    • If people had infinite time thatâ(TM)s be true, but as it stands people eat mediocre meat based food because it takes really good vegan food that takes much more time and effort to compare to it.

        • Re:

          This isn't criticism, just information. But in my experience, and in the experience of other vegetarians and vegans I've talked to who used to eat meat: you have a desiring for meat for like a couple weeks, but then it gets entirely replaced by desires for other foods, while the concept of eating meat steadily seems grosser and grosser. Like, if you want something that makes my mouth water thinking about it, it's not going to be a hamburger, it's going to be something like falafel. Even though I grew up ea

            The foods that replace meat in your desires are generally ones with similar nutritional properties - fatty, protein-rich, etc. The mind isn't really requesting "meat", it's requesting fat, protein, etc.

            I've always wondered though What creates the vegan need to shame, and impress others with their superiority? I have vegetarian friends and colleagues, most are not overbearing.

            In a university environment, I've been around a fair number of vegans, and the meme has some merit. Certainly not to say that all vegans are that way, but enough to make the stereotype accurate.

            Just as one example, We employed a vegan for a while in my group. To keep her from another of her lectures, we only had permissible snacks in the office. We had a weekly group lunch. After a few weeks of her interrogating the waitstaff and the managers, even at vegan eateries, taking up most of the lunch hour with her demands and inspections that nothing that ever touched meat touched her food, then us getting lectured for having cheese on pizza, sad stares and sighs. The luncheon was doomed.

            First the guys stopped going. The women didn't want to upset the vegan, so they continued for a couple weeks. Then they too stopped. It wasn't the only unpleasantness, as our office group had to comply with her edicts, lest the lectures again. We made a good faith effort, but it was walking on eggshells. Then she left.

            The most memorable part of all her time at our work was her going away party.

            It was the day after she left. My treat, Burgers and Cheese Fries for everyone. The luncheons resumed.

            But that's just one of the more story-worthy tales. The others were just basic being around vegans was an unpleasant experience.

            • What creates the vegan need to shame

              Well, there's that whole "animal has to die for you" thing. It's a little difficult to put a similar weighting on those who don't eat animals, though it's worth noting that raising and harvesting vegetables tends to be pretty hard on vegetable-consuming wildlife, barring some really careful farming.

              Personally, I think cultured meat offers an excellent path forward, presuming we can make it work. Which actually kind of looks like it is going to happen.

              • Everything dies. If anything The logical shame would be unto something to die uselessly.

                So it still is a bit of a quandary, how they generate shame and response to an environmental Norm.

              • Re:

                No its not hard to put the whole animal has to die thing on vegans either, if they are extreme. They will not some won't eat food cooked in the same kitchen as meat, with the same utensils, or have people eat meat in the same resturant. Going to these extremes causes animals to die, you have to build extra facilities, use extra farm land, while not directly killing the animal your are taking their resources so you can effectively feel good about yourself.

                Just look what the example extreme vegan did, wasted

                • Re:

                  Notice the difference here, between you and so many vegans. I don'r know any "I'm better than you" vegetarians, and I've never had issues.

                  For full disclosure, I did know one vegan - actually a fruitarian - who dod not fit the mold. She ran a vegetarian food truck, and made some kickass sandwiches. Miso pate with alfalfa spouts on whole wheat and oatmeal bread was my favorite.

                  She was the sweetest woman, kind and friendly, no lectures or attitude from her. You didn't find out she was a fruitarian until y

              • Re:

                Still, vegans are just as much killers as any human. They either kill life themselves, or pay others to kill life for them. That is an inescapable fact - unless they eat rocks. I would be happy to go to cultured meat. It is a zero cruelty zero harm to other animals solution that allows humans to get their required nutriments.

                What is more, just imagine the exotic meats that will be available, without harming any animals.

                What will be interesting is the loss of the vegan superiority narrative.

            • Re:

              While I have absolutely seen the overbearing vegetarian or vegan in my experience it's more often the overbearing meat eater giving a friend of mine shit for having the nerve to sit there quietly not eating meat. Some people just can't stand the fact that some do things differently and act like their mere presence is a challenge to how they live.

              • Re:

                There is an interesting difference. If I have vegans over to my place for an evening or a party. I will go out of my way to prepare a special meal for them that has no animal products.

                If invited to a vegan's place, not one will prepare a meal with anything other than vegan food.

                And I'm not familiar with the shit dealing meat eater you reference. If we would have dared to criticize vegans on campus, a trip to HR and sensitivity training and possibly a warning against our employment would be the order

            • Re:

              It is the person, not the Veganism. If they weren't a Vegan, they would be telling you how they don't own a TV, or how great CrossFit is, or about their religion, or... It is a psychological need to be seen as better than others. Many of these people you are referencing are Vegan BECAUSE it gives them something to be superior about.

  • Re:

    Nobody is going to be replicating the exact flavor of Coca-Cola until other companies are also permitted to import the Coca plant to flavor it. They may not get to keep the cocaine from their import (that goes to a pharmaceutical company), but it's still that exotic ingredient that's literally impossible for anyone else to obtain. It would be just as difficult to replicate the flavor of a cow's meat, if a ranch's industry secret was raising it on cocaine, even if you had the same breed and similar condition

  • Re:

    "even among the real stuff there's significant variation in quality" I see, so even the real stuff doesn't taste like the real stuff. Will the real stuff please stand up and say "here"? Maybe being the real stuff is a quantum property, it is there but only if you do not taste it.

    • Re:

      Good ol' No True Scottsman argument.
      This cultivated eel is made from stem cells taken from a fertilized eel egg. It's eel meat. This isn't some ultra processed plant based meat like the Impossible Burgers (not knocking them though... those do taste pretty great IMO). I don't see why meat eaters would get up in arms about eating meat that was grown specifically to be meat; That's the direction cows have been going for ages anyway. If they were REALLY into eating only REAL animals, then they'd stick to wild g

      • Re:

        This. A veggie burger is not some sort of sin against humanity, and it's difficult to see lab grown meat as a sin either.

        Mebbe I'm a troll, but on a social media site I posted a picture and description of a meal I like - A veggie burger topped with my home made bacon. That got a lot of reponses! Veggie burgers can be darned good, although a few varieties are way over-spiced.

          Once again, this proves that BACON is the world's most perfect food!!

          It is the only food you wrap around other food to make it taste better!!!

          • [Bacon] is the only food you wrap around other food to make it taste better!!!

            Bread would like to have a word... pita... buns... sandwiches in general... stuffed vegetables... etc.

              Nope..bread is just something to HOLD food together....NOT a flavor enhancer.

              Bread, for the most part is bland and flavorless.

              • Well bad bread is bland and tasteless. Like you there are many people who have never had good bread and so mistake the limits of their experience for the larger picture.

                  Don't get me wrong, I LOVE a good stuff poboy...but to me bread is a lot like a baked potato.

                  To me a potato is pretty much flavorless...just a 'binder' for sour cream, butter, salt, pepper and cheese. I always have mine in a bowl and by the time I'm finished with it...looks

  • Re:

    Yet, some people prefer Pepsi. So it shall be with lab meat. Not exactly the same but not entirely different.
  • Re:

    Walmart is known to add a saline solution to ground beef to preserve the color (make it look fresher longer). If an animal died to give you food, the least you could do is treat the meat with respect.
