In this study, the nutrients of a total of 4 species of popcorn, Oryun Popcorn, Oryun Popcorn 2, GPopcorn and Gichan Popcorn, cultivated in Gangwon-do, were analyzed and compared. The contents of these products, including their general ingredients, inorganic substances, fatty acids, reducing sugar and starch, were analyzed. The moisture, crude ash and crude fat content of the dried popcorn species were 11.54-12.54%, 0.97-1.45% and 2.48-2.62%, respectively. The crude protein content was 9.68-11.75%. As for inorganic substances, the potassium and phosphorus content were the highest. Potassium was 228.25-310.46 mg/100g and was the highest in Oryun Popcorn, and the content of phosphorus was 276.04-310.00 mg/100g. As for fatty acids, 11 types were detected. The content of linoleic acid accounted for 52.89-55.76% of the total fatty acid content showing the highest amount followed by oleic acid (24.31-26.65%) and palmitic acid (14.20-15.92%). As for amino acids, total 16 types of amino acids were detected by specie, with glutamic acid making up 17.70-18.52% of total amino acids, the highest, followed by leucine (12.30-12.54%) and proline (10.34-10.92%) in that order. The creducing sugar content by specie was 4.68-5.13% and starch content was 42.14-46.14%.
