SPACE FOOD??
“Space foods are food products specially
created and processed for consumption of
astronauts in outer space.”

ONWARDS TO MARS
• The new goal will be to create foodstuffs that last far longer than the 2-3 yr shelf-life
• light, edible, transportable, safe and nutritious
• a)Hydroponic system b)Aeroponic system
![Page 22: space food technology](https://reader031.fdocuments.in/reader031/viewer/2022020710/554aa1fdb4c905da668b46a1/html5/thumbnails/22.jpg)

HYDROPONICS SYSTEM Subset of hydro culture and is a method
of growing plants using mineral nutrient solutions, in water, without soil.
BenefitsI. Potential for a larger variety of foodII. Regenerative life support system.
![Page 23: space food technology](https://reader031.fdocuments.in/reader031/viewer/2022020710/554aa1fdb4c905da668b46a1/html5/thumbnails/23.jpg)

HOW THE WATER GETTING??Fuel cell provide electricity
Fuel cell convert energy into electricity
by chemical reaction
By-product is water vapour
water vapour condensed into liquid
![Page 28: space food technology](https://reader031.fdocuments.in/reader031/viewer/2022020710/554aa1fdb4c905da668b46a1/html5/thumbnails/28.jpg)

NUTRITION • Amount of iron in an astronaut’s diet should be
less than10 milligrams per day• Amount of sodium in the astronaut’s diet is limited• Scientists use a formula for Basal Energy
Expenditure (BEE)• For women, BEE = 655 + (9.6 x W) + (1.7 x H) - (4.7
x A).• For men, BEE = 66 + (13.7 x W) + (5 x H) - (6.8 x A) W = weight in kilograms, H = height in centimeters
and A = age in years

previous week• Computer results are sent electronically to the
ground• Nutrition specialists analyze the data • So they can recommend ways to improve the
astronaut’s dietary intake

5.IRRADIATED FOOD• NASA first used irradiated meats in 1972 on Apollo
• Irradiated meat had higher organoleptic acceptability compared to its thermally processed counterpart
• Irradiation process involves cooking, packaging, and freezing the meat products
• The meats are irradiated at to a minimum absorbed dose of 44 kGy.
![Page 37: space food technology](https://reader031.fdocuments.in/reader031/viewer/2022020710/554aa1fdb4c905da668b46a1/html5/thumbnails/37.jpg)
04/11/2023 37
6.FROZEN FOOD

• Include quiches, casseroles, and chicken pot pie.
![Page 38: space food technology](https://reader031.fdocuments.in/reader031/viewer/2022020710/554aa1fdb4c905da668b46a1/html5/thumbnails/38.jpg)
04/11/2023 38
7.FRESH FOOD• Fresh fruits and vegetables are minimally
processed
• Sanitized with a 200 parts per million (ppm) chlorine rinse – to ensure food safety
• Air-dried and then placed on a food tray into a fresh food locker
• Vegetables like carrots and celery, are packaged in sealable bags
![Page 39: space food technology](https://reader031.fdocuments.in/reader031/viewer/2022020710/554aa1fdb4c905da668b46a1/html5/thumbnails/39.jpg)
04/11/2023 39
• Oranges, pears, grapefruit, and jalapeno peppers have also flown occasionally.
• Bananas and oranges became less popular -because they produce odor
• 2 to 3 days for most fresh fruit and vegetable • Fresh fruits metabolize and cannot be sealed
in a container
• So a controlled atmosphere package
![Page 40: space food technology](https://reader031.fdocuments.in/reader031/viewer/2022020710/554aa1fdb4c905da668b46a1/html5/thumbnails/40.jpg)

FLAVOUR
• Flavour change was accompanied by a change in colour
• Non enzymatic or Millard browning reactions
• With the implementation of non thermal technology off-flavour development in these types of meat products could be avoided

• Fruit and dessert between 1.5 and 5 y
• Vegetable side dishes 1 to 4 y
• Soups and starch side dishes1.75 to 4 y
• Dairy products & vegetarian entrees2.5 to 3.25 y
• Meat products with an expected shelf life maximum of 8 y
OBSERVATION

04/11/2023 66
RESULTS
• Shelf life endpoints were established for all of NASA’s retorted pouch products.
• At ambient storage conditions, shelf life endpoints of the products range from 0 to 96 month,depending on the product formulation.

GAMMA IRRADIATION
• Samples were irradiated in a cobalt-60 gamma irradiator
• Dose rate :- 10kGy/hr

04/11/2023 74
RESULTS
• Evaluation of total aerobic bacteria,coliform bacteria, Staphylococcus, Salmonella, E. coli, B. cereus, and fungi in miyeokguk & freeze dried miyeokguk
• Colonies were not detected within the detection limit of l.00 log CFU/g for any microbial species
![Page 75: space food technology](https://reader031.fdocuments.in/reader031/viewer/2022020710/554aa1fdb4c905da668b46a1/html5/thumbnails/75.jpg)
04/11/2023 75
• Aerobic bacteria were not detected in any sample just after gamma irradiation above 10kGy
• These results indicate that gamma irradiation of 10 kGy is enough to inactivate all microorganisms in the freeze- dried miyeokguk
![Page 76: space food technology](https://reader031.fdocuments.in/reader031/viewer/2022020710/554aa1fdb4c905da668b46a1/html5/thumbnails/76.jpg)
04/11/2023 76
CONCLUSION
The result of this study indicate that gamma irradiation at 10 kGy could sterilize freeze-dried miyeokguk without deterioration of the sensory quality of the food

CONCLUSION
– Space food technology- hope to be adapted in our daily lives on earth
– Sooner can see space foods even on the shelves of departmental stores
– The day is not so far………….
