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."

      After the function ends, the astronaunts die. I think I've read that astronauts "consume" 10kg of materials (air,water,food) per day so that it would cost 300kg to support somebody for a month if nothing ever got recycled. What space colonists need is a simple food-chain like this:

      ----> while (1) { plants(Sun, Fertiziler); silkworm(Plants); humans(Silkworm); }

      In this way, you can recycle the processed waste from the silkworm and the humans (i.e. the "Fertilizer") and combine that with available Sunlight to generate a continuous cycle of food. And when "not dying" is the goal, it really won't matter how it tastes.

      Citation: In space, there is a bit less biodiversity than on Earth. It wouldn't be a stretch to assume that it might be a bit difficult for astronauts to maintain a balanced diet if vegans here on Earth are having trouble doing so.

      Actually, insect protein is about as close to eating vegetarian, environmentally, as you can get without being a vegetarian.

      Of course, you can survive on a vegetarian diet, but it's not always the easiest or lowest impact way of eating. For example, you can buy a goat for a third world family from a non-profit development agency. They graze on things humans (and indeed most animals) can't eat, but they produce milk, wool and eventually meat at very little cost. I've bought some of these. For $175, you can change a family's life.

      Pigs used to graze this way too, before the advent of factory farming. Here in New England, we have a kind geological feature called a drumlin; it's basically a low, rounded hill of glacial debris. Where a chain of drumlins reaches into the ocean, you get modest sized islands of a few acres, sometimes separated from the mainland by a narrow strip of water and connected at high tide. A number of these islands used to bear the name "Hog Island" (until the developers get their hands on them, after which they get names like "Spinnaker Island"). The reason is that in colonial times people drove their pigs on the island and let them run free until it was time to slaughter.

      But insects are by far the most efficient animal when it comes to food conversion, and the quality of that food is, from a nutritional standpoint, outstanding. Unfortunately, insect consumption is fading away in many cultures, as they turn to a more western diet.

  26. Potato Chips on a Sub by kenp2002 · · Score: 2, Interesting

    A Navy friend of mine worked on a Sub for many years. He always thought it was ironic that for a mission that required stealth they always seemed to have some of the loudest food you could find. Even MREs are edible, normal food.

    Nothing in the exploration of space requires such nonsense self-depravation and oddities that keep getting leaked. I swear this is just a poly for more money.

    Flour Torillas and refried beans is a remarkable compact food with spreadable cheese (think like butter) is easy to make. Even in zero G. Microwave it and you are good to go. The ideal of using silk worms is laughable when canned pastes and flat breads store very densely.

    Here is a great "at home" experiment. Make a PBJ upside down. Doable with jelly in a squeeze bottle.

    I mean seriously this is the most idiotic thing I have heard.

    Can of refried beans is a more dense food source.

    Suppliments can handle any short comings in the food supply.

    How about:
    Peanutbutter
    Refried Beans
    Tuna
    beef jerky
    whole grain frozen bagels
    squeezy cheese
    triscuits
    Pringles
    etc...

    All of those can be packed\frozen\thawed with little trouble in dense formats.

    Hell I know body builders that live on nothing but hard boiled eggs, whole grain bagels with peanut butter, diced chicken, milk, and tuna fish. 7 days a week. Years on end (excluding unusual meals on dates, holidays, etc.)

    Chicken meat can be processed much like Spam and con be stored in a very compact space. Taking a cue from Tuna packaging you can use lightweight, vaccum sealed mylar bags to store the food. I have not tried freezing a hard boiled egg and thawing one to eat but bagels and even peanut butter seem to survive the freezer ok.

    The key is density and as usual all things can be measured against SPAM for food density... :)

    1. Re:Potato Chips on a Sub by rudeboy1 · · Score: 3, Insightful

      What you're not getting, is that they're concerned with finding a food source that can be replicated while en route to Mars. Say the Mars crew was 5 people strong. 3 years is 1095 days. For 5 people to eat 3 square meals a day, that's 5475 servings of food. Scratch that, not servings, but complete meals, which generally represent at least a couple servings of various food groups. The concern is that A.)You're packing a ton of extra weight that has to break Earth's gravity, and then adding in additional fuel to compensate, which then makes the craft even heavier. B.) That much food, even in compact forms like tuna cans and beef jerky, is still going to take a massive area just for storage. Again, extra weight added to craft for additional spacecraft real estate. C.)Survivability. Most of the foods you listed will not keep at room temperature for 3 years. Tuna, perhaps, but jerky, bagels, etc. Won't make it even close to that. You can freeze it, but this will also require extra gear, energy and materials to accomplish.

      Now, if you were to introduce a renewable food source like the silk worm, most of those problems are reduced considerably. You leave orbit with only a seed population, and since their bodies, much like ours, are comprised mostly of water, it is not a straight equation of 1LB of worm food begets 1LB of worms. They eat leaves, which could theoretically also be grown using a minimum of resources, which only require light (free), water (recyclable) and soil (recyclable). Therefore you are netting a gain in food that is more than what you leave with from Earth.

      I'm sure they will probably pack some regular food too, but likely more as an appeasement to keep the astronauts sane. It will be spaced out sparingly over a long ride, and is essentially a luxury. I view it a lot like the food situation in Firefly, where most of their diet is comprised from nondescript protein bars. If you didn't see the behind the scenes of them making those protein bars, I think you'd be looking at a very similar set of circumstances. Once the worms have been harvested, they can be processed any number of ways, including being refined and compacted into their most efficient form (bars). Then you add in a box of strawberries every now and then just to keep from going all bibbledy.
