Abstract

Inulin is one of many functional food components that becomes a trend nowadays. Inulin can be found in the stems and roots/tubers of plants. Yellow sweet potato (Ipomea batatas L.) is a widespread species of sweet potato with abundant availabilty in Indonesia, where it is exploited only as a source of carbohydrate. From the previous study, it was stated that sweet potato can be used as an alternative resource of inulin besides dahlia and Dioscorea spp. tubers. This study aimed at extracting and isolating inulin from aqueous extract of yellow sweet potato with 3 different ratio (1:1, 1:2, 1:3) and 3 different time (6, 12, 18 hours) to determine its effect on the yield of inulin. After preparation of extracts, crude inulin was precipitated in 96% ethanol. The free reducing sugar from sweet potato flour was tested using Dinitrosalisylic Acid Method (DNS). After precipitation, inulin powder was obtained by an overnight drying process using oven at 60ºC and characterized by color, solubility, water absorption, moisture content and ash content. Its inulin structure was analyzed and confirmed by Fourier Transformed Infrared (FT-IR) spectroscopy. The results showed that different ethanol ratio and precipitating time has effect on the yield of inulin. The highest yield of inulin were 8.80% obtained from solvent ratio 1:3 with 18 hours of precipitating time. It can be concluded that yield of inulin were affected by solvent ratio, precipitating time and degree of polymerization (DP). Higher solvent ratio and precipitating time could obtain higher yield of inulin.

Abstract

Tanaman cincau hijau rambat (Cyclea barbata L. Miers) sudah banyak dikenal masyarakat sebagai bahan pembentuk gel dalam pembuatan minuman segar.  Salah satu kelemahan cincau hijau rambat adalah mudah mengalami sineresis.  Penambahan hidrokoloid diharapkan mampu menurunkan nilai sineresis sehingga gel cincau hijau rambat lebih tahan lama. Kappa karagenan merupakan jenis hidrokoloid yang diekstrak dari jenis rumput laut Kappaphycus alverizii yang mampu memberikan peningkatan viskositas dan pembentukan gel.  Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penambahan kappa karagenan terhadap karakteristik fisik dan kimia gel cincau hijau rambat. Pembuatan gel cincau hijau rambat dilakukan dengan menambahkan berbagai konsentrasi kappa karagenan (0,0%; 0,3%; 0,4%; 0,5%; dan 0,6%). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan satu faktor perlakuan. Data yang diperoleh dianalisis dengan One Way ANOVA, dan jika berbeda nyata maka dilanjutkan dengan uji Duncan Multiple Range Test (DMRT) pada taraf signifikansi α = 5%. Hasil penelitian ini menunjukkan bahwa semakin tinggi konsentrasi kappa karagenan yang ditambahkan maka nilai tekstur, kadar air, kadar abu, pH, serat kasar, dan aktivitas antioksidan meningkat. Sedangkan pada parameter sineresis dan rendemen mengalami penurunan.
