Analysis of Regional Characteristics of Free Amino Acids in Pulp of    Nagafu 2,, Apples from Different Habitats

Abstract

Abstract: Objective: To analyze the regional characteristics of free amino acids (FAAs) in pulp of Nagafu 2,, apples from ten habitats. Methods: The contents of free amino acids were measured by automatic amino acid analyzer. Principal component analysis was conducted and eleven kinds of FAAs were classified as four principal components. Apples from different habitats were described as six categories in scatter diagrams generated by the first and the second principal component analyses combined with apple regionalization. Results: Comprehensive indices showed that different habitats could result in the difference in the contents of FAAs, which suggested that the method for measuring the contents of FAAs by automatic amino acid analyzer was feasible. Principal component analysis could be used to analyze regional characteristics of FAAs in pulp of Nagafu 2,,apples effectively.

Key words: apple, free amino acid, principal component analysis, regional characteristics
