abstract- mechanical damage degrades fruit quality in the chain from production to the consumption. damage is due to static, impact and vibration loads during processes such as harvesting, transportation, sorting and bulk storage. in the present study finite element (fe) models were used to simulate the process of static bruising for apple fruits by contact of the fruit with a hard surface. thr...

ABSTRACT- For most fruit types, including apples, bruising is the most common type of postharvest mechanical injury. Bruise susceptibility was investigated in 3 commercial cultivars (‘JazzTM’, ‘Granny Smith’ and ‘Fuji’) and among a range of 4 different fruit sizes (commercial counts of 135, 120, 100, and 88) in each cultivar. Bruising was carried out by dropping a uniform round steel ball (110g...

Bruising is defined as damage of fruit tissue as a result of external forces which cause physical changes of texture or chemical changes of color, smell and taste. With the development in imaging technology, on-line detection of bruises on fruits & vegetables is feasible. Proposed system is developed for finding surface and subsurface defects along with their sizes in percentages with respect t...

One of the main factors that cause to quality loss for fresh fruit market apples is bruise damage. Amongst the factors that affect apple sensitivity to bruising, major one is drop height and area profile during the impact. In the present study, four Iranian apple varieties consisted of Atirli, Kapak, Kowse and Paiez that were selected and 100 fruits of each variety were picked up, then apples w...

abstract- the purpose of this study was to elucidate the effects of chemical thinning on seasonal variations of leaf and fruit mineral compositions of ‘soltani’ apple trees. treatments, including unthinned control, naphthalene acetic acid (naa) at 5 and 10 mg l-1, naphthaeneacetamide (nad) at 25 and 50 mg l-1, benzyladenine (ba) at 50 and 100 mg l-1 and carbaryl at 500 and 1000 mg l-1 were appl...

abstract- bruising degrades the quality of fresh apple fruits. reducing bruise damage is of utmost importance in designing and developing processing equipments. the main objective of the present study was to introduce an analytical method to predict the allowable static load applicable to apple fruits. to predict the strain energy absorbed by the fruit, a point load was applied on the solid sph...
