PERBANDINGAN HASIL PENETAPAN KADAR VITAMIN C MANGGA DODOL DENGAN MENGGUNAKAN METODE SPEKTROFOTOMETRI UV-Vis DAN IODOMETRI

Abstract

ABSTRACT
Vitamin C is one of the nutrients that role as antioxidant and effectively overcome the free
radicals that can damage cells or tissue. Fruit is a good source of vitamin C, such as the
mango fruit. This study aimed to determine the levels of vitamin C in the mango fruit using
UV-Vis spectrophotometry method and Iodimetry method, and compare the results of both
methods. Samples were identified as ripe mango. In this study, the levels of vitamin C were
analyzed by using UV-Vis spectrophotometry and Iodimetry. The results of the analysis of
vitamin C in the mango dodol by using UV-Vis spectrophotometry is 15.88 g/100g, whereas
the content of vitamin C by using Iodimetry was 3.5 g/100g. From these results, showed the
levels of vitamin c by using the spektrofotometry uv-vis method is higher than the iodimetry
method.
