Extensions1. Have the class design their own ISS food menu for a30-day crew rotation or Space Shuttle food menu for a7-day rotation. Have them analyze how many times aparticular food or drink item was served and if someitems were served in combination with another (suchas fish always served with french fries). Avoid monotonousor repetitive selection by increasing the varietyof food choices.2. Using a computer, create a data base file. Design adata base template that includes fields such as day (1,2, 3, etc.), meal (breakfast, lunch, dinner, and apossible snack), and the six major food groups (grain,vegetable, fruit, dairy, meat, and oil). Enter the informationfrom the menus and determine which mealsare balanced ones by searching for any empty fields inthe food groups.AssessmentThe students will compare and contrast their findings.22 • Space Food and Nutrition An Educator’s Guide With Activities in Science and Mathematics, EG-1999-02-115-HQ
Activity 5:Ripening of Fruits and VegetablesObjectivesCompare and contrast the rate of ripening of fruits andvegetables when exposed to air and the effect of using achemical inhibitive on that rate of ripening.Measure the exposed surface area of ripened fruits andvegetables.Science Standard• Science as Inquiry: Abilities necessary to do scientificinquiry• Life Science: Matter, energy, and organization in livingsystems• Science in Personal and Social Perspectives:Personal healthMathematics Standard• MeasurementMaterials NeededDistilled waterFruits such as apples and bananasVegetables such as carrots and celery sticksVitamin C tabletsSmall deep plastic bowlsKnifeLarge spoonsPaper platesBACKGROUNDFood for the Space Shuttle is packaged and stowed infood lockers at Johnson Space Center in Houston,Texas, approximately a month before each launch and iskept refrigerated until shipped to the launch site. About3 weeks before launch, the food lockers are sent toKennedy Space Center in Florida. There, they arerefrigerated until they are installed in the Shuttle2 to 3 days prior to launch. Besides the meal and supplementalpantry food lockers, a fresh food locker ispacked at Kennedy and installed on the Shuttle 18 to24 hours before launch. The fresh food locker containstortillas, fresh bread, breakfast rolls, fresh fruits such asapples, bananas, and oranges, and fresh vegetables suchas carrots and celery sticks. During space flight, freshfruits and vegetables have a short shelf life because ofthe absence of a refrigerator and must be consumedwithin the first 7 days of flight. Carrots and celery sticksare the most perishable items in the fresh food lockerand must be consumed within the first2 days of flight.Onboard the ISS, refrigerators will be present, and refrigeratedfoods for the Station will include fresh and freshtreatedfruits and vegetables. Certain types of fruits andvegetables can have an extended shelf life of up to 60 days.When certain fruits or vegetables are sliced open andexposed to air, the exposed cut surface turns brown incolor. There are a number of processing techniques thatcan be employed to fresh-treat fruit and vegetables: irradiation,a wax coating, an ethylene inhibitor (ethylene isa plant hormone that causes ripening), controlled atmospherepackaging, modified atmosphere packaging, andthe use of a chemical inhibitive.This activity focuses on one of these processes the useof a chemical inhibitive as a way of packaging slicedfruits and vegetables as a single-serving, nonwaste fooditem. Slicing eliminates the weight and waste of a coreand peelings.Some foods are easily browned, such as bananas, apples,pears, and peaches. You can protect fresh fruit frombrowning by keeping it from being exposed to air.Another way is by treating the food with vitamin C.Procedure1. Pour water into two small deep bowls. Dissolve avitamin C tablet into one, and leave the second asplain water. Label the first one Vitamin C and thesecond Plain Water.2. Cut a piece of fruit into six equal wedges.3. Place two wedges into each of the prepared liquids. Becareful that each wedge is completely immersed in theliquid for about 10 minutes.4. Remove each wedge with a spoon, and place on separatelylabeled paper plates.5. Place the last two wedges on a paper plate labeledUntreated.6. Arrange the piece so that all of the cut surfaces areexposed to air.7. Repeat steps 2 through 6 with each fruit and vegetablebeing tested.Space Food and Nutrition An Educator’s Guide With Activities in Science and Mathematics, EG-1999-02-115-HQ • 23
