Abstract
Umbi Porang (Amorphophallus Puelleri) memiliki kandungan glukomanan yang
mempunyai kemampuan untuk mengikat air dan dapat membentuk gelling agent,
sehingga mampu meningkatkan keelastisan dan kekenyalan. Hambatan yang terdapat
pada pemanfaatan umbicporangcadalahckalsium oksalat yang terkandung cukup
tinggi. Permen jelly merupakan makanan yang memiliki kalori tinggi
berbahan dasar air, gula, dan sirup fruktosa. Bahan pembentuk gel yang digunakan
dalam pembuatan permen jelly sangat berpengaruh terhadap tekstur permen karena
tekstur pada permen jelly yang dihasilkan akan memiliki teksturckenyal sesuai
dengan penambahan pembentuk gel yang digunakan. Tujuan dari penelitian adalah
untuk mengetahui efek penggunaan umbi porang dan karagenan terhadap
karakteristik fisik dan sensori permen jelly. Penelitian dilakukan menggunakan
rasio karagenancdan tepung porang. Tepung porang dibuat menggunakan umbi
porang yang terlebih dahulu direndam di dalam larutan NaCl 8% dilanjutkan
dengan perlakuan perendaman menggunakan etanol untuk menurunkan konsentrasi
kalsium oksalat. Penelitiancdilakukan dengan menggunakan rancangan acak
lengkap (RAL) 1 faktor yaitu 4 variasi rasio karagenan:tepung porang (100:0,
75:25, 50:50, 25:75).peningkatan konsentrasi tepung porang cenderung
meningkatkan hardness dari permen jelly. Konsentrasi tepung porang yang
meningkat menyebabkan warna dari permen jelly semakin coklat dan lightness
menjadi semakin rendah. Karakteristik permen jelly dari formulasi rasio
karagenan:tepung porang 75:25 dengan skoring kekenyalan sebesar 3.46 ± 1.22,
penerimaan keseluruhan 5.46 ± 0.89, dan total gula reduksi sebesar 16.5 ± 0.09. / Porang tubers (Amorphophallus �uelleri) contain glucomannan which can bind
water and can form a gelling agent, so it can increase elasticity and suppleness. The
obstacle found in the use of porang tubers is calcium oxalate which is contained
quite high. Jelly candy is a high-calorie food based on water, sugar, and fructose
syrup. The gelling ingredients used in making jelly candy greatly affect the texture
of the candy because the texture of the resulting jelly candy will have a chewy
texture according to the addition of the gelling used. The purpose of the study was
to determine the effect of using porang and carrageenan tubers on the physical and
sensory characteristics of jelly candy. The study was conducted using the ratio of
carrageenan and porang flour. Porang flour is made using porang tubers which are
first soaked in an 8% NaCl solution followed by soaking treatment using ethanol to
lower the concentration of calcium oxalate. The study was conducted using a
complete randomized design (RAL) of 1 factor, namely 4 variations in the ratio of
carrageenan: porang flour (100:0, 75:25, 50:50, 25:75). The increased concentration
of porang flour causes the color of the jelly candy to become browner and the
lightness to become lower. Jelly candy characteristics of the formulation of
carrageenan ratio:porang flour 75:25 with a chewiness score of 3.46 ± 1.22, overall
receipt of 5.46 ± 0.89, and total reduction sugar of 16.5 ± 0.09.
