Abstract | A study was conducted to identify the characteristics of three diff ere ntmaturities of man goes and precooling tr eatments subjected to controlled compressi on and impactloads . In significant damage onimma tureand mature mangoes subjected to compression in the r ange of 5 - 30 k g were noticed. Bruise was observed on the surface of th eripe mangoes but no s u c h tr acescould be observed in imma tu re and ma tur e man goes. Im pact d a mage in i mmature and ma tu re ma n goes b y d ropp in g a l ong its w idth r es ult e d in a fl es h which was w hit e (p a le ) in color , t ear in g and vo i ds orig in ate d from the see d. Bru i ses o f ripe mangoes caused b y compression formed a c u rve d bound ary or ig in ati ng from th e area und e r th e s kin . The hi g h e r forc e app li ed res ult ed in increase d brui se vo lum e. Im pact bruising of ripe m angoes were only observed wh e n th e e n ergy app li ed was hi g h er than 0.013 J. Energy absor b ed i nd i cated a lin ear corre lation to bruis e vol ume either for compressi on testin g or for drop testi ng. The exper iment showed that e n ergy a b so rb e d durin g compress i on an d imp act is a good meas u re to predict bruis in g and therefore could be a u sefu l parameter to evaluate handlin g and packag in g sys t e m s. Peak force an d e n ergy a t imp ac t was a l so o b served to be an im porta nt f actor caus in g br ui se in mangoes. Damage in mangoes was found to be highl y dependent on th e st or age condit i ons of the fruits. |
