The delectable and advanced fruits and vegetables that are found at the grocery have most in all likelihood been address to amend ledge lifetime using atomic number 6 dioxide as a refrigerant or as gasoline to control insects and pathogens . Carbon dioxide is used to execute the storage length and flavor of fruits and vegetable by 50 per centum to 100 percentage , reports Adel Kader for the University of California . The addition of CO2 during the refrigeration process reduce the level of damage from chill . package of certain vegetables are fill with CO2 to reduce spoilage .

Transportation

Fruits and vegetables are shipped all over the country in refrigerated trucks and shipping container that apply atomic number 6 dioxide gas to foreshorten decline , chill damage and time required for ripening . Carbon dioxide level of 60 percent with 1 pct atomic number 8 are effectual in kill insects that may be hiding in leave of absence and stem of tropic fruit and vegetables , as stated in a composition by Adel Kader . The gas fills the compartment during transport and prevents fruits and vegetables from ripening too quickly .

Packaging

The bagged scratch industriousness uses CO2 extensively to prolong the glow of lettuce . Lettuce is ill-famed for indulge , and many leaf type are now packaged in bags that are filled with CO2 and O levels of only 1 percentage to 3 percent . This combining kill microorganisms that have decay , as well as insects . The appearance of the lettuce may be beautiful and frosty right on out of the bag , but there is vexation that CO2 does not preserve the vitamins .

Frozen Foods

fruit and vegetables are frozen and box for the grocery store using a method that employs the use of C dioxide in nimble - frozen applications . Pipelines from CO2 storage tank figure into the Deepfreeze , which birth a mist of hunky-dory snow onto fruits or vegetables that are being frozen at temperature of minus 60 Fahrenheit , according to Jim Lane for BioFuels Digest . This method of cryogenic freezing freeze food in a matter of minutes as opposed to hours using mechanically skillful method . frigid foods using this method retain colour and insolence much longer than food freeze by mechanical methods .

Insect Eradication Without Pesticide

Traditional method acting of killing insects on fruits and vegetables employed the role of methyl bromide fumigation , used by exporters . Insects must be bolt down on all imported fruits and vegetables , because their introduction into the ecosystems of the United States could wipe out total solid food crops . The employment of low - level oxygen unite with gamey CO2 storey pour down all insects , including microscopic pathogens . It is a food - conservation engineering that is much safer for humans and the planet .

Economics

Using carbon copy dioxide for preserve fruit and veggie deliver money and time and prevents wastage of fruit and veggie . Farmers , packagers and consumers all benefit from this . No consumer will buy a fruit or a vegetable if its appearance is decayed or if bugs have destroy it . Fruits and vegetable naturally mature by time of year ; and with the use of CO2 , crops can endure farseeing storage periods , make for a longer window of saving of fresh fruit and vegetables to the consumer .
