Abstract
This study aimed to compare the nutritional value of two local cultivars of purple sweet potatoes from West Java and Central Java Indonesia. The proximate analysis was conducted to investigating the percentage of protein, carbohydrate, ash, water, total fat, total energy and energy from fat. Amino acid analysis was conducted using Ultra Performance Liquid Chromatography except the tryptophan by High Performance Liquid Chromatography. West Java cultivar were relatively higher content of carbohydrate, ash, total fat and total energy than Central Java cultivar. Central Java cultivar relatively higher protein and amino acid content. The three highest amino acids in Central Java cultivar were aspartate 2550.2 mg/kg, glutamic acid 1711.9 mg/kg and leucine 1127.8 mg/kg. Meanwhile, the three highest from West Java cultivar were aspartate 1214.8 mg/kg, glutamic acid 1177.8 mg/kg, and phenylalanine 667.9 mg/kg. Methionine was detected as the lowest amino acid in Central Java cultivar and were not detected in West Java cultivar. We assumed that Central Java cultivar have better protein and amino acid content than West Java cultivar. Further study is required to explore the nutrition benefit of both cultivars.
