Four varieties of grape raisins where made in traditional way and investigated for their chemical composition, mineral elements and total antioxidanst capacity. Results reveals that there were significant differences in the average percentage of m oisture and carbohydrate between varieties, whereas the protein, fat and ashes percentages were not significant. Results of minerals analysis showed that blue raisins had the highest amount of Calcium, phosphorous and potassium with a level of 66 mg, 193 mg and 989 mg in 100 g raisins respectively. In addition, the total polyphenol contents by Folin- Ciocalteau assay were higher in blue (257 mg) and red raisins (213mg) when compared to the others varieties and vitamin C was 45mg/100g and 34 mg/100g in blue and red raisins respectively. The antioxidant activity of raisins was assessed by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay. The amount of raisins needed to scavenge 50% of DPPH radical (EC50) was similar for all varieties ranging from about 4.18 mg to 6.41 mg. Total antioxidants capacity were in descending order blue >red > white > green raisins. Therefore, the consumption of raisins is considered to contribute the intake of antioxidants and minerals in Syrian diet .
During the season of 2002, samples of olive fruit were taken (Ashrasi type) from Ninavah horticulture’s station that belongs to the ministry of agriculture in Iraq. The purpose of this research is to study some physical and chemical characteristic s during the growing period, from July until October. Those characteristics include moisture, ash, oil content, chlorophyll A & B, protein, pH and carbohydrate, In addition to fruit length, size, weight, radius, and rigidity. The results showed significant increase in moisture, oil, weight, size and length of the fruit were studied. Significant reduction was noticed in the percentages of the protein, carbohydrate, ash and the fruit rigidity. The highest values of chlorophyll were observed during The month of September. October considered as the best time to harvest olive fruits for pickle purpose.
