Detection and nutritional assessment of fresh sweet corn 520

Nutrition composition of fresh sweet corn was detected and evaluated for new products.Amino acid, fatty acid, sugar compositions were analyzed by amino acid analyzer, gas chromatography and iron chromatography respectively.The results showed that fresh sweet corn contained 12.08% protein, 6.66% fatty acid, 2.41% ash.Soluble carbohydrate was 11.98% ( in wet basis) in which 86% was fructose. Comparing to infant essential amino acid model, AAS of leucine, sulphur amino acids, phenylalanine and tyrosine, valine were 1.11, 1.80, 1.09 and 1.03.Meanwhile, AAS of Histidine, isoleucine, lysine and threonine were 0.83, 0.75, 0.52 and 0.99 respectively which were insufficient for infant. In conclusion, the fresh sweet corn was sufficient in leucine, sulphur amino acids, valine, phenylalanine and tyrosine, but was short of histidine, isoleucine, lysine and threonine as infant food. Main unsaturated fatty acids were linoleic acid and linolenic acid.Main soluble sugar was fructose.
