Astronautit ovat kaukana kaupoista, joten heid\u00e4n on turvauduttava s\u00e4\u00e4nn\u00f6llisiin elintarviketoimituksiin. Muutaman kuukauden v\u00e4lein saapuu automaattinen avaruusalus, kuten ESA:n Automated Transfer Vehicle tai ven\u00e4l\u00e4inen Progress, lastattuna tuoreilla hedelmill\u00e4, vedell\u00e4 ja valmiiksi pakatuilla aterioilla.<\/p>\n<\/div>\n

Ruokailu avaruudessa on parantunut huomattavasti siit\u00e4 ajasta, jolloin tarjolla oli vain kylm\u00e4\u00e4 tahnaa alumiiniputkissa ja kuutionmuotoisia suupaloja. Nyky\u00e4\u00e4n avaruusruoka muistuttaa hyvin paljon sit\u00e4, mit\u00e4 sy\u00f6d\u00e4\u00e4n p\u00e4ivitt\u00e4in Maassa. Siihen kuuluu pakastettuja vihanneksia ja j\u00e4lkiruokia, kylm\u00e4varastoituja elintarvikkeita, hedelmi\u00e4 ja maitotuotteita. Nyky\u00e4\u00e4n Kansainv\u00e4lisen avaruusaseman ruokalistalla on yli 100 ruokalajia. Astronautit valitsevat p\u00e4ivitt\u00e4iset ruokalistansa jo kauan ennen avaruuteen l\u00e4ht\u00f6\u00e4. P\u00e4iv\u00e4ss\u00e4 on kolme ateriaa sek\u00e4 v\u00e4lipaloja, joita voi sy\u00f6d\u00e4 milloin tahansa. Tarjolla on my\u00f6s mausteita, kuten ketsuppia, sinappia ja majoneesia. Suolaa ja pippuria on saatavilla, mutta vain nestem\u00e4isess\u00e4 muodossa.<\/p>\n

Avaruusruoka voi olla purkissa tai k\u00e4\u00e4ritty alumiinifolioon. Se voi olla kylm\u00e4kuivattua, v\u00e4h\u00e4kosteista, esikypsennetty\u00e4 tai kuivattua (josta vesi on poistettu). Jos ruoka on kuivattua, sit\u00e4 ei voi sy\u00f6d\u00e4 ennen kuin astronautit lis\u00e4\u00e4v\u00e4t siihen kuumaa vett\u00e4. Ruokien l\u00e4mmitt\u00e4miseen sopivaan l\u00e4mp\u00f6tilaan on k\u00e4ytett\u00e4viss\u00e4 uuneja. Monet juomat ovat my\u00f6s kuivattuja. Asemalla tuotetaan jonkin verran kierr\u00e4tetty\u00e4 vett\u00e4, mutta lis\u00e4varastoja on l\u00e4hetett\u00e4v\u00e4 yl\u00f6s huoltolentojen yhteydess\u00e4. Juomavalikoima ulottuu kahvista, teest\u00e4 ja appelsiinimehusta hedelm\u00e4punchiin ja limonadiin.<\/p>\n

Riitt\u00e4v\u00e4n kalori-, vitamiini- ja kivenn\u00e4isaineiden saanti on yht\u00e4 t\u00e4rke\u00e4\u00e4 astronautille kuin maapallolla asuville ihmisillekin. Heid\u00e4n on sy\u00f6t\u00e4v\u00e4 v\u00e4hint\u00e4\u00e4n 2000 kaloria p\u00e4iv\u00e4ss\u00e4. Lennon aikana miehist\u00f6n j\u00e4senet t\u00e4ytt\u00e4v\u00e4t tietokoneella kyselylomakkeen, jossa he ilmoittavat, mit\u00e4 ruokia ovat sy\u00f6neet. Maassa olevat asiantuntijat antavat heille neuvoja, jos heid\u00e4n ruokavaliotaan on syyt\u00e4 parantaa.<\/p>","protected":false},"excerpt":{"rendered":"
