Abstract

Tubers included in the family Araceae contain a lot of calcium oxalate. High calcium oxalate consumption in the body can cause health problems. One of these examples is in the kidneys. Tubers with high levels of calcium oxalate, if immersed in acidic solutions, calcium oxalate levels can be reduced. In this research, immersion of porang flour in starfruit juice, lime juice and vinegar with the aim that the calcium oxalate content contained in it can be reduced. Calcium oxalate levels were analyzed by permanganometric titration method. The results of this study indicate that acidic solutions can reduce calcium oxalate levels in porang flour. Calcium oxalate levels were analyzed by permanganometric titration method. The results of this study indicate that acid solution can reduce calcium oxalate levels in porang flour. The 7% Averrhoa bilimbi juice solution was able to reduce calcium oxalate levels by 62.68%. The 5% lime juice solution gives better results than the Averrhoa bilimbi juice solution. The 5% lime juice solution can reduce calcium oxalate levels by 65.94%. The biggest decrease in calcium oxalate levels was shown in porang flour after soaking it with 20% vinegar acid solution, which amounted to 90.27%.

Abstract

Degenerative disease is a disease caused by a decrease in the condition of the human body. Degenerative diseases can be prevented with a healthy lifestyle, one of them is consuming foods with high fiber. One of the high-fiber foods that are being developed at this time is the porang tuber. Glucomannan, which is mostly contained in porang tubers, is a polysaccharide that is easily soluble in water and high in fiber. Besides containing glucomannan, porang tubers also contain lots of calcium oxalate which can cause irritation to the tongue and mouth when consuming it. Calcium oxalate levels can be lowered through immersion in acidic solution. Solution that can be used to reduce calcium oxalate levels in porang tubers is lime. Soaking time is one of the factors that affect the reduction of calcium oxalate levels. Porang tubers that have been immersed in 5% lime solution for 60 minutes showed the highest decrease, namely 31.79%. In addition, soaking at high temperatures can decrease calcium oxalate levels in porang tubers also. Porang tubers that have been immersed in a 5% lime solution at 60 ° C, the calcium oxalate level has decreased to 49.58%.
