Test Results and Levels Determination of Vitamin C With Titrimetric Method

Determine the content of vitamin C levels or at a natural food source is carried out in a laboratory test. Where people who do it usually because it has entered the realm of higher education. So that the test results are not uncommon levels of vitamin C may differ between laboratories with each other. Fruits and vegetables that contain vitamin C are green peppers, red peppers, guava, kiwi, broccoli, lychee, papaya, strawberries, oranges, cabbage, lemon, cantaloupe, cauliflower, garlic, grapefruit, tangerines, mandarin oranges , passion fruit, spinach, mango, potato, tomato, pineapple, grapes, watermelon, banana, avocado.

A total of 15 milliliters of solution was taken and placed in 100 ml Erlenmeyer flask and add 25 milliliters of I (0.1 N); 5 milliliters of H2SO4 (2 N) after it was titrated with 0.1 Nagsgog. Up to young yellowish color. This process is called the process of determining the levels of vitamin C by titrimetry. That is not a direct titration.

Added 2 drops of starch by 5% and then continued until a deep blue color disappeared. Literacy is done in the triple. This procedure is done also for the blank, ie without guava juice. The amount of vitamin C is determined through calculations that every mole of moles of I2 would be oxidize ascorbic acid in a reaction redoks.Banyaknya I (z) which can react with ascorbic acid, calculated from the difference between the blank titration used to test samples of guava juice. So in get the vitamin C content in guava fruit is 228.3 milligrams per 100 grams of guava.

According to the results of research on the determination of vitamin C for a variety of natural food sources for each dose of 100 grams as follows. Levels of vitamin C in tomatoes 34 milligrams.
