Biotech Companies Are Trying To Make Milk Without Cows (technologyreview.com) 70

Posted by msmash from the next-frontier dept.
Avian influenza outbreaks on US dairy farms have raised concerns about milk safety, leading some to consider alternatives like engineered milk proteins. Startups like Remilk and Alpine Bio are using yeast and soybeans to produce key milk proteins, aiming to replace dairy cows and reduce environmental impact. However, competing with subsidized dairy industries and their efficient use of cow byproducts remains a challenge for these biotech ventures, MIT Technology Review reports. The story adds: Everyone agrees that cow's milk will be difficult to displace. It holds a special place in the human psyche, and we owe civilization itself, in part, to domesticated animals. In fact, they've left their mark in our genes, with many of us carrying DNA mutations that make cow's milk easier to digest. But that's why it might be time for the next technological step, says Alpine's CEO Magi Richani. "We raise 60 billion animals for food every year, and that is insane. We took it too far, and we need options," she says. "We need options that are better for the environment, that overcome the use of antibiotics, and that overcome the disease risk." It's not clear yet whether the bird flu outbreak on dairy farms is a big danger to humans. But making milk without cows would definitely cut the risk that an animal virus will cause a new pandemic. As Richani says: "Soybeans don't transmit diseases to humans."

        Aren't those mostly due to contamination from water that came from animal production, for example runoff? So if you took the factory farms out of the loop, the water wouldn't be contaminated and the soybeans wouldn't contain those pathogens.

        Except fungi. That's getting worse, as pathogenic fungi acclimate to higher maximum temperatures. Though the worst change isn't the byproducts they produce in grains, but their new ability to thrive at a mammal's body temperature.

          Yet hilariously you can even find yeast companies doing recall for listeria and salmonella.... don't know what happened there, FDA recalls don't say.

          What if the biotech firm making these proteins has problem has contaminated water supply... seems that could do it. maybe that happened to the yeast makers?

          I'm pretty certain that non-factory farms will even be worse. One of the reasons that milk is now pasteurized is that a fair number of people - especially children, were killed by pathogens in raw milk.

    • Even E.coli from a poorly rinsed crop could falsify this.

      Raw soybeans are toxic. They contain trypsin inhibitors [wikipedia.org] that block the digestion of protein.

      The heat required to destroy the toxins will also kill any E. coli.

      • Inhibitors are not a pathogen. You fail.

      • Besides this, E coli are a normal gut bacteria, which are in your gut right now. However, the strain of ecoli that cows like to have in their guts are different than the ecoli you like to have in your guts. If there are nasty E.coli 0157:H7 on the soybeans, it probably came from cows.

      Richani is full of the male bovine excreta. Even if not a disease as such, soybeans contain a lot of phytoestrogens, and a lot of people are getting way too much of them. And some are getting them way too young. https://www.sciencedirect.com/... [sciencedirect.com] Some general soybean effect info: https://www.ncbi.nlm.nih.gov/p... [nih.gov]

      Not to say that we should not eat soy products, but moderation is definitely indicated. And women of childbearing age who plan on getting pregnant should really be careful. https://www.sciencedire [sciencedirect.com]

      Cows will then become rare and exotic, meaning that we'll suddenly have to protect them with ham-fisted regulations.

      You're thinking of pasteurized milk. People do die from drinking unpasteurized milk. As for stubbed toes, you'd be hardpressed to find a case of someone dying from a stubbed toe. Jack Daniels did, but how long ago was that? in the 1900s, over a 25 year period, roughly 65,000 died from drinking raw milk [healthline.com]. That's 2,600 people dying each year. How many died during that same time from a stubbed toe?

      Between 1987 and 2010 [fda.gov] there were 3 deaths, 6 stillbirths, and 3 miscarriages. That we know of. Most likely there were more due to underreporting. How many died from a stubbed toe during that same time?

      As for a disease vector [sciencealert.com]:

      Out of all the food-borne illnesses linked to dairy products, raw milk and raw cheese are responsible for no less than 96 percent.

      • A lot of that has to do with how rare it is for people to get sick from dairy products, so any problems would stand out. I have never known anyone to get sick, and I was raised on a dairy farm many, many years ago. We drank raw milk all the time.

      • Yeah, raw milk deaths from before proper refrigeration is a rather irrelevant comparison.

    • People used to get sick from milk once in a while. There are even (bad) things a mother can pass to her infant with good old all-natural breastfeeding.

      The reason so few people get sick drinking milk in modern times is pasteurization. And yes, farmers sometimes drink (and promote the drinking of) raw milk, but it remains a dumb idea when pasteurization is available.

      • No, the primary reason so few people get sick from drinking milk these days is electric refrigeration and especially refrigerated trucks. Pasteurization takes that small number and further cuts it down. Without electric refrigeration, pasteurization becomes significantly more important to preventing disease.

      Part of the disease risk is raw milk, the other part is that livestock farming is a common way for novel pathogens to breed and eventually make the jump into humans.

      I also wonder if this tech could safely produce raw milk (it supposedly tastes better), but I'm guessing there would still be a non-trivial pathogen risk.

      I live in a non-white majority country but every convenience store sells milk. Every grocery stores sell milk. Some of the ethnic (non-white) store categories always carry milk. Milk is a major thing internationally, though I can't pinpoint which part of your claim leads to that mistaken conclusion.

        That is a kind of myth, that popped up a few decades ago.
        But there is a grain of truth in it. If there is no "milk drinking culture", and eating cheese does not really count, then adults indeed easy get lactose intolerant. But that happens to Europeans/Caucasian, too. But with a bit of diligence: it can be reverted. On the other hands there entire regions or Ethnics in Africa and China that get very quick lactose intolerant during chi

    Some of the bovine casein proteins mimic regions of myelin-associated glycoprotein (MAG) (AKA myelin oligodendrocyte glycoprotein (MOG)), which is expressed by oligodendrocytes. These are the cells responsible for producing myelin. An allergy to these proteins will sometimes produce antibodies that also attack the body's own MAG/MOG.
