Raisins are in fact dried grapes The grapes are called sultanas if they are dipped before drying Doing so accelerates the drying process and the grapes are then ready in days They vary in colour from light brown to dark brown In Turkey different colour numbers are assigned to raisins from number 7 dark brown to number 11 very light brown Number type 9 is the most popular colour in the
Table Grapes Postharvest Quality Maintenance Guidelines
postharvest diseases of table grapes primarily because it develops at temperatures as low as 31oF (-0 5oC) and grows from berry to berry Gray mold first turns berries brown then loosens the skin of the berry its white thread-like hyphal filaments erupt through the berry surface and finally masses of gray colored spores develop Wounds on berry surface near harvest provide opportunities

Grape withering is a process used to produce reinforced wines and raisins Dehydration is usually carried out postharvest by keeping ripe grapes in special warehouses in controlled conditions of temperature relative humidity (RH) and air flow Alternatively grape clusters can be left on the vines after the canes have been pruned In general dehydration increases stilbenes in grape but
POSTHARVEST HANDLING OF TABLE GRAPE
The main deterioration factors of table grapes during storage at low temperature are decay and water loss The non-climacteric (minimum ethylene production during ripening) response of fruit ripening and the low respiration rate determine that softening is not a relevant postharvest problem as in the majority of fruits In the case of decay gray mold is considered the universal disease and
