Abstract

Pengaruh suhu pengeringan porang terhadap kadar glukomanan dan oksalat telah diteliti. Variasi pengeringan yang digunakan adalah oven dengan suhu 45, 50, 55, dan 60℃, serta pengeringan dengan matahari. Kadar glukomanan dianalisa dengan metode gravimetri, sedangkan kadar oksalat dianalisa dengan titrasi permanganometri. Analisa glukomanan menghasilkan kadar tertinggi pada suhu 55℃ sebesar 51,62%. Uji ANOVA menunjukkan bahwa suhu pengeringan yang optimum yaitu 55℃ berpengaruh terhadap tingginya kadar glukomanan. Nilai kadar oksalat pada porang menurun seiring menurunnya suhu pengeringan, dengan kadar oksalat terendah diperoleh pada suhu 45℃ sebesar 5,37%. Uji ANOVA menunjukkan adanya pengaruh suhu pengeringan terhadap menurunnya kadar oksalat. ==================================================================================================== The effect of drying of porang tuber toward glucomannan and oxalate content has been studied. Variation of drying used are oven drying with temperature of 45, 50, 55, and 60℃, and sun drying. Glucomannan content analyzed by gravimetric method, while oxalate content analyzed by permanganometric titration. The results showed that the highest glucomannan content was 51,62% in 55℃. ANOVA analysis shows optimum drying temperature, 55℃, affected the high glucomannan content. The results showed that oxalate content decreased with temperature, which lowest content is 5,37% in 45℃. ANOVA analysis shows drying temperature affected the decrease of oxalate content.
