AWAYINTRODUCTIONFruits are important sources of vitamins and
carbohydrates like fiber and sugar. They are low in calories and
naturally sweet. Fruit and their juices are good sources of water.
Different fruits contain different vitamins, so it is important to
eat a variety of fruits.RESEARCH BACKGROUNDHealthy lifestyle among
the students affected nowadays. Students lack choice of fruits in
hostel cafeteria. The frequency of students purchasing fruits
decreases.Therefore, I came out with this idea for make sure the
students have a healthy lifestyle.PROBLEM STATEMENThostel students
can afford those fruits either from cafeteria or canteen but the
students doesnt have much choice.one of the way to make sure they
can get a healthy lifestyle is by taking variety of fruits in
addition. Hostel surrounding weather makes the fruit ripened fast.
As a s solution, I came out with a idea of Fruit SaverPURPOSEFruits
will ripened fast if not placed in right atmosphere (Kader,1992)We
have a lot of method such as vacuuming, preserving and so on.The
quality of fruits are not remain same by using those methods.
(Barry-Ryan, Martin-Diana et.all,2007)Thus, some idea sparks in my
mind which doesnt change the naturalists of fruit and slow down the
ripening of fruit.
HYPOTHESISDoes the Fruit Saver slow down the ripening process of
fruit? Does the Fruit Saver able to prolong the quality of
fruits?Does the frequency of students will increase the tendency of
purchasing fruit weekly?SCOPEThe fruits to ripen slowly by keep the
appearance of fruits remain. Hostel students can keep the fruits
for a longer period to consume and doesnt have problem of lack of
choices in cafeteria and canteens. IMPORTANCELack of facilities
among hostel students.(Refrigerator)Rules that not allowed to cook
in hostels.Lack of choices of fruits at hostel cafeteria and
canteens.This lead to decrease the tendency of students purchasing
fruits. I still want to take variety of fruitsBut, with FRUIT
SAVER[Still dont have refrigerator, but I will not to purchase at
cafeteria and canteens, I will purchase by own]Because I HAVE FRUIT
SAVER8LITERATURE REVIEWModified atmospheres are frequently used in
packaging and storage of fruits and vegetables. These conditions as
well as edible coatings can also be successfully adapted to
fresh-cut fruits and vegetables. Modified Atmosphere Packaging
Among other benefits the use of modified or controlled atmospheres
consequently extends storage life of products.
(Kader,1992)LITERATURE REVIEWThe industry takes its best apples and
essentially puts them to sleep, sometimes for up to 11 months. In a
process called controlled atmosphere storage apples are kept at
zero degrees and deprived of oxygen, which slows their metabolic
rate to prevent full ripening. This blocks the fruit's ethylene
production, switching off its ripening. (McGlasson.
Montagues)LITERATURE REVIEWFruit ripening is largely caused by a
plant hormone called ethylene, which is a gas. Most fruits give off
ethylene in ever increasing quantities as they ripen, and we can
use this to our advantage when ripening fruit.Ethylene production
increases as temperature rises, which is why you may have noticed
that your fruit ripens quicker in the summer than in the
winter.(Andrew Perlot)LITERATURE REVIEWEthylene is an invisible,
odorless, naturally occurring gas that aids in the ripening process
of fruit. As a fruit produces more ethylene, it begins to create
enzymes which help break down cell walls and starches, making the
fruit softer and sweeter over time. If it weren't for this small
hydrocarbon gas, the shelf lives of most fruits could last well
over a year.(The Kitchn)LITERATURE REVIEWCarbon Dioxide / Oxygen.
As fruit ripens, it's respiration decreases the oxygen in a
ripening room and emits carbon dioxide. Concentrations above 1%
will retard ripening, delay the effects of ethylene and cause
quality problems. Therefore regular ventilation is required to keep
carbon dioxide levels below 1%.(Dennis Kihlstadius,2014)LITERATURE
REVIEWEthylene action slows at lower temperatures.At their minimum
temperature levels, fruit is basically inactive and does not
respond well to externally supplied ethylene.
(Dennis Kihlstadius,2014)LITERATURE REVIEWThere are a few simple
steps you can take to control how quickly your fruit produces
ethylene, and by extension, manage its shelf life. With proper
storage and temperature control, Apples can stay fresh and edible
for up to ayear!
(The Kitchn)EXISTING PRODUCT
VACUUMING SYSTEM The fruits and vegetables placed in a plastic
and the air in the plastic sucked by vacuum and sealed. This was
the method used to keep fruit and vegetables for long period. The
products that produced are mainly use method of controlling the
airFRUIT SAVERADVANTAGESeco-friendlydoesnt change by the taste,
doesnt change by the smelldoesnt change by the color
FRUIT SAVERDISADVANTAGESproduct cost is literally high compare
to the product in market but AFFORDABLE
