Pengaruh Penambahan Dekstrin dan Kulit Buah Naga Merah terhadap Karakteristik Fisiko Kimia dan Organoleptik Serbuk Mangga Gadung Klonal 21

Abstract

Mango Gadung Clonal 21 (Mangifera indica L.) is the result of crossbreeding between Gadung Mango and Arumanis, acknowledged as a native fruit of Pasuruan Regency. However, the sales of this fruit decline during the peak harvest season, causing difficulties for farmers in processing ripe fruit. Therefore, technology is needed to enhance shelf life and create innovative products using Mango Gadung Clonal 21 (Mangifera indica L.) as the base ingredient, with the addition of antioxidants from red dragon fruit peel. The aim of this research is to assess the physicochemical and organoleptic characteristics and identify the best combination of adding dextrin and red dragon fruit peel to Mango Gadung Clonal 21 (Mangifera indica L.) powder. This study employed a randomized block design with two main factors: the addition of red dragon fruit peel extract (M) with 2 levels (15 grams and 20 grams) and the addition of dextrin (D) with 3 levels (15 grams, 20 grams, and 25 grams). The study was repeated three times, resulting in a total of 18 treatments. Analysis encompassed antioxidant activity, water content, solubility, as well as organoleptic evaluations of color, aroma, taste, and texture. The best results were observed in the M1D3 treatment (15 grams of red dragon fruit peel and 25 grams of dextrin), with an antioxidant activity of 58.96 mg/ml, water content of 9.15%, solubility of 79.31%, color rating of 3.56 (liked), taste rating of 3.8 (liked), aroma rating of 3.04 (somewhat liked), and texture rating of 3.76 (liked).   Keywords: Antioxidant, Clonal 21 gadung mango, Dextrin, Red dragon fruit skin
