Turk­ish univer­sity de­vel­ops new shelf-life ex­tend­ing pack­ag­ing

Daily Sabah (Turkey) - - Lifestyle -

SABANCI Univer­sity de­vel­oped Nano clay-re­in­forced shelf life-ex­ten­der pack­ag­ing.

De­vel­oped by Sa­bancı Univer­sity, Nano clay-re­in­forced pack­ag­ing tech­nol­ogy, which ex­tends the shelf life of prod­ucts, was pro­moted at the “Amer­i­can Chem­i­cal So­ci­ety Na­tional Meet­ing” held in Wash­ing­ton, D.C.

The project was led by Hayriye Ünal, a re­searcher at Sa­bancı Univer­sity Nan­otech­nol­ogy Re­search and Ap­pli­ca­tion Cen­ter. De­vel­oped un­der the ti­tle of TÜBİTAK ARDEB 1003, the project con­sul­tants are Yusuf Menceoğlu, Dean of Sa­bancı Univer­sity Fac­ulty of En­gi­neer­ing and Nat­u­ral Sciences; Fevzi Çak­mak Ce­beci, aca­demic mem­ber of Sa­bancı Univer­sity Fac­ulty of En­gi­neer­ing and Nat­u­ral Sciences and Serkan Ünal, a re­searcher of In­te­grated Manufacturing Tech­nolo­gies Re­search and Ap­pli­ca­tion Cen­ter.

Re­searcher of Sa­bancı Univer­sity Nan­otech­nol­ogy Re­search and Ap­pli­ca­tion Cen­ter (SUNUM), Ünal and her team de­vel­oped a pack­ag­ing film con­tain­ing clay nan­otubes that were equipped with var­i­ous func­tions to meet the needs of mul­ti­di­men­sional pack­ag­ing. The film has a shelf life ex­tend­ing qual­ity for per­ish­ables by pre­vent­ing the over-ripen­ing of fruits and veg­eta­bles and pre­vent­ing mi­cro­bial growth on meat.

Giv­ing in­for­ma­tion on the stud­ies, Ünal said, “Thanks to such ac­tive pack­ag­ing [items], we can im­prove food se­cu­rity con­di­tions and re­duce the eco­nomic loss faced due to spoiled food.” Ünal also stated that it is pos­si­ble with this tech­nol­ogy to de­sign cost-ef­fi­cient pack­ag­ing suit­able for var­i­ous food cat­e­gories.

Re­searchers of Sa­bancı Univer­sity Nan­otech­nol­ogy Re­search and Ap­pli­ca­tion Cen­ter eval­u­ated the pro­duc­tiv­ity of the new pack­ag­ing by com­par­ing it with or­di­nary poly­eth­yl­ene film. They pack­aged foods like toma­toes, ba­nanas and chicken in the newly-de­vel­oped Nano clay-en­forced film. At the end of day 10, the food pack­aged in the new Nano clay tech­nol­ogy were ob­served to be in bet­ter con­di­tion than the foods pack­aged in the other ma­te­rial. Also, at the end of day six, the ba­nanas pack­aged in the new tech­nol­ogy were fresher and their color were more vivid. The chicken wrapped in Nano clay film was ob­served to pro­duce less bac­te­ria than the chicken wrapped in an or­di­nary film.

Ünal stated that they con­tinue con­duct­ing stud­ies on pre­sent­ing the new Nano clay-en­forced pack­ag­ing sys­tem to the mar­ket as well as the tests on the safety of the newly de­vel­oped films on con­tact with food­stuff.
