Abstract
Many foods from Indonesia are cooked through the frying process using cooking oil. Good cooking oil is oil that has a low amount of peroxide and acid. The purpose of this study was to find the effect of adding dragon fruit juice (Hylocereus undatus)to peroxide numbers and acid numbers in used cooking oil. Peroxide numbers were measured using the iodometry method, whereas acidic numbers were carried out by the acid-base method. The results of this study indicated that after the addition of dragon fruit juice the peroxide number was dropped to 2.4 meg / kg, whereas in acid numbers an acid number was increased to 6.08 percent.
印度尼西亚的许多食物都是用食用油油炸的。好的食用油是含有少量过氧化氢和酸的油。本研究的目的是研究龙果汁(Hylocereus undatus)对废油中过氧化值和酸值的影响。过氧化氢数用碘量法测定，酸性数用酸碱法测定。研究结果表明，加入火龙果汁后，过氧化氢含量降至2.4 meg / kg，而酸含量则增加到6.08%。
