Abstract
Pop corn forms appetizer wide use by different age groups in many occasions, especially the children of school age, so we went towards the study of its chemical composition ;determination the amount of calories processed; and its content of some essential amino acids and essential vitamins. Therefore we selected six samples of popcorn from five different areas belonging to Salah al- din province which are displayed in the local markets and prepared at the traditional way by the vendors by a preparation machines of popcorn. The results showed that the humidity content range was 12.0-13.8%, protein 7.6 - 10.1%, while each of fat and ash giving percentages ranged from 3.8 - 4.2% and 3.1 - 4.2%, respectively, carbohydrates were ranged from 69.4 -72.2%. A study of the content of some of the essential amino acids, which included methionin , cystin, lysine , arginine and tryptophan, showed that there range were 0.13-0.18 , 0.14-0.18 , 0.22 -0.26 , 0.06 -0.10 and 0.38 -0.41 g / 100 g nitrogen, respectively. The calculated amount of calories processed by eating 100 grams of popcorn ranged between 349.0 -358.2 Kcal. The determination of some essential minerals showed that there content were 25.3 – 30.6 mg of calcium, 0.56-0.76 mg of iron, 23.6 - 31.3 mg of manganese, 225.6 -248.6 gm of phosphorus , 230.3 -245.6 gm of potassium, and 0.43-0.9 mg of zinc / 100 grams of popcorn. The assessment of some of the essential vitamins, including thiamine, riboflavin, niacin, pyridoxine, and folic acid showed that the content were 0.195-0.250 mg, 0.60-0.80 mg , 0.6-1.75 mg , 0.55 -0.7 mg , 20.5- 23 mg / 100 g of popcorn respectively.
