Hidrolisis Limbah Kulit Nanas dengan Asam Asetat Menggunakan Metode Ultrasound-Assisted Acid Hydrolysis (UAAH) untuk Produksi Oligosakarida

Abstract

Pineapple peel waste has a lot of fiber and carbohydrate content so that it has the potential to become raw material for making oligosaccharides. Oligosaccharide production can be done through hydrolysis with acidic compounds. This research aims to determine the effect of ultrasonic waves application in acid hydrolysis to pineapple peel waste. Hydrolysis was carried out with 0.5 M acetic acid with variations in volume of 10, 15, 20, 25, and 30 mL as well as variations in the time of use of ultrasonic waves for 5, 10, 15, 20, and 25 minutes. The results of hydrolysis showed varying Rf in the analysis using thin layer chromatography (TLC).Based on Rf, oligosaccharides have been produced (Rf ≤ 0.64), including the smallest solvent volume (10 mL) and the shortest duration of ultrasonic wave application (5 minutes).
