For evaluating the changes in date fruit as a result of infestation with date palm dust mite. infested date fruits Barakawi cultivar in "Tamr" stage (dried fruit) were collected from infested bunches of 4 date palm trees selected randomly from an orchard in Dongola area. Sound fruits (not infested trees) were also randomly collected, and were sent to the Food Research Centre at Shambat to determine the changes in physical properties, chemical composition and nutritional value. The results indicated that sound Barakawi date fruit were of a significant higher value as physical characteristics, fruit length, width, weight, pulp weight, seed weight, flesh thickness, pit percentage and surface area. Insignificant difference among tested fruits in fruit length/width ratio and pulp/seed ratio. Also, the results indicated differences between the infested fruits and sound ones in moisture content, total sugar, reducing sugar, sucrose, carbohydrates where the sound fruits recorded higher contents than infested one. Protein and fibre contents were recorded significantly different values and were found higher in infested fruits.
