Pemanfaatan Ubi Jalar (Ipomoea Babatas, L.) Menjadi Sirup Glukosa Dengan Hidrolisis Asam

Abstract

Sweet potato (Ipomea babatas, L.) is a tuber plant that contains carbohydrates, calcium, and starch. Besides being consumed as food, sweet potato can be used as a raw material for making glucose syrup. The study aimed to investigate the effect of hydrolysis time and HCl volume on glucose production. The starch was extracted from sweet potatoes then deposited for an hour. The glucose syrup production was carried out by acid hydrolysis method at 100°C. The results showed that the highest glucose content of 62.76% was obtained at 30 minutes hydrolysis time and 15 ml HCl volume. The smallest glucose content is obtained at the longest hydrolysis time. The greater the volume of HCl, the smaller the glucose content. @2020 Published by UP2M, Faculty of Mathematics and Natural Sciences, Sriwijaya University Kata Kunci: Ubi jalar; Glukosa; Hidrolisis asam; Pati ABSTRAK: Ubi jalar (Ipomea babatas, L.) merupakan tanaman umbi yang mengandung karbohidrat, kalsium dan pati. Selain dikonsumsi sebagai bahan pangan, ubi jalar jug bisa digunakan sebagai bahan baku pembuatan sirup glukosa. Penelitian ini bertujuan untuk mengkaji pengaruh waktu hidrolisis dan volume HCl terhadap produksi glukosa. Pati diekstrak dari ubi jalar kemudian diendapkan selama 1 jam. Produksi sirup glukosa dilakukan dengan metode hidrolisis asam pada suhu 100°C. Hasil penelitian menunjukkan kadar glukosa tertinggi sebesar 62,75% diperoleh pada waktu hidrolisis 30 menit dan volume 15 ml HCl. Kadar glukosa terendah dihasilkan pada waktu hidrolisis terlama. Semakin besar volume HCl, semakin kecil kadar glukosa yang diperoleh. @2020

Development of Processed Products Made from Sweet Potatoes into Sweet Potato Milk (Violatte) to Improve the Economy of the Community in Dopang Village, West Lombok Regency

“…Sweet potatoes contain vitamins, minerals, dietary fiber, and bioactive compounds and have a low glycemic index. Sweet potatoes contain around 16-24% starch and have been widely used for the production of glucose and highfructose syrup (Shitophyta, 2020).…”
