Salak Pondoh Sleman, a local name for snake fruit in Sleman, is one of the Indonesian Geographical Indication (GI) commodities, which has unique quality characteristics that strongly related to its geographical origin. Besides Sleman, especially in Java Island, snake fruit are also cultivated widely in Magelang and Banjarnegara, in which the fruit have been grown, may have their own unique characteristics and potentially promoted also as GI products. Therefore, quality evaluation on the snake fruits obtained from these three producing regions had been conducted to reveal their characteristic differences. This study aimed to characterize quality parameters of snake fruits from these three producing regions, to find out distinguishing quality parameters, and to visualize the studied characteristics. Samples of snake fruits were taken directly from orchards in Sleman (Tempel, Turi, Pakem), Magelang (Salam and Srumbung), and Banjarnegara (Madukara and Banjarmangu) regions. The regions were selected based on their fruit production levels and their altitudes. Selected chemical (total sugar; tannin; titratable acid; crude fiber; and vitamin C) and physical properties (fruit size; texture; peel and pulp colors) were then analyzed. The obtained data were tested with ANOVA and Principal Component Analysis (PCA). While ANOVA was used to determine whether the significant difference of the quality parameters between one geographical origin to the others existed, PCA was used to visualize the sample’s characteristics based on their geographical origin. We observed that snake fruit from Sleman tends to have a lower tannin content, bigger fruit’s size, and yellowish pulp color, whereas the fruit from Magelang tends to have higher tannin content and brighter peel color. Meanwhile, the fruit from Banjarnegara tends to have the highest total sugar and tannin contents, as well as darker yellow pulp color. We also found a significant difference in each chemical and physical properties, implying that quality characteristic differences of the fruit from the three studied regions existed. Three principal components with overall variety value of 63.91% were produced and showed the characteristics similarity of most region’s snake fruits except those from Tempel and Banjarmangu. © 2016 The Authors.
