Future Astronauts May Survive On Eating Silkworms

sciencehabit writes "Science reports that silkworms may be an ideal food source for future space missions. They breed quickly, require little space and water, and generate smaller amounts of excrement than poultry or fish. They also contain twice as many essential amino acids as pork does and four times as much as eggs and milk. Even the insect's inedible silk, which makes up 50% of the weight of the dry cocoon, could provide nutrients: The material can be rendered edible through chemical processing and can be mixed with fruit juice, sugar, and food coloring to produce jam."

    Now we just have to solve this space radiation issue and how to shield astronauts from it.

      Hmmm, given the article's topic, now I wonder if they ever tested the radiation shielding properties of silk.

      Hey if that works, they've got the solution to space travel all wrapped up!

      In space, yes. Outside the earth's magnetosphere, no. Even out on the moon, the magnetosphere still protects them from much of the nastiness (solar wind, cosmic rays, etc.), but if we're gonna go to Mars or wherever, we'll need to bring our own protection.

      From what I understand, it's almost impossible for people to have sex in Zero-G. Male Astronauts have apparently tried quite a bit, even with the help of drugs, but they -can't- get an erection.

      This makes sense since most of the blood in your body flows to your head when you're in Zero-G.

      Sorry to burst all of your geeky dreams.

    With enough butter, anything can taste okay. The best part is their texture though. Nice and silky.

    They taste kind of like a very musty bean, but they have the typical cooked larva mouthfeel to them, a slightly taught exterior that 'pops' when you bite into them, and a soft creamy interior.

    I'm not just talking shit either. Silk worms are a very common street vendor food in Korea, and I tried some the last time I was there. I'd seen them for decades, but I'd chickened out when I saw them in my earlier years.

    If I was in some sort of survival environment, like the harsh vacuum of space, I wouldn't mind eating silk worms, but on a regular basis, I'm not too fond of them.

    so what do they taste like?? can we make them taste like bacon?

    Last year I was in Korea where the streets are lined with vendors frying up silkworm pupae on the street as an, *ahem*, delicacy. The smell wafting down the road can only be described as a cross between death and pus. I would eat my fellow astronauts over silkworms.

  9. The mass still has to come from somewhere by nasor · · Score: 5, Insightful

    The big issue with space missions in mass. Silk worms aren't going to magically create silk worm meat (or whatever you call it) from nothing - for ever 1 kg of silk worm that you grow to eat, you will have to bring along at least 1 kg of silkworm food. So why not just bring human-edible food instead of silk worm food?

    1. Re:The mass still has to come from somewhere by A.+B3ttik · · Score: 5, Informative

      Several points:

      1) The article states that Silkworms seem to be the most compact form of Human-edible food. 1kg of Silkworm Meat will give you far more nutrients and proteins than 1kg of Chicken meat.

      2) For a long-term space mission, (we're talking at -least- decades from now) you would need a renewable food source that ultimately converts solar energy into consumable chemical energy, since Humans can't eat sunlight. So futuristic Arcology-like spaceships might have greenhouses to harness solar energy, and astronauts could eat grown food. However, even Vegans need vitamin supplements and the article states that for protein and nutrient purposes, Silkworms make a great compact, efficient, renewable food source.

    Space travel is extreme backpacking! If you've ever backpacked, you don't think twice about eating food you wouldn't normally eat at home. There are various gateway foods you can eat, such as sushi and in particular uni (sea urchin testes...no shit...nasty), which will make the consumption of silk worms seem like dessert. Hunger is a powerful motivator.
