IDENTIFICATION OF CHLORINE CONTENT (Cl2) IN BULK RICE SOLD IN NORTH SURABAYA AREA

Rice (Oryza sativa) has remained one of the most important food sources, dating back to a
time before the recording of history began. Food is a critical substance necessary for the human body
and an essential element for human life. The primary functions of food are as an energy source and
for building new body tissues. However, in this regard, many traders add hazardous chemical
additives, such as bleach, as food additives, which is a cause for concern among consumers due to
their potentially harmful effects. Therefore, the use of these chemicals is a significant concern for
consumers because of their highly dangerous effects. The aim of this research is to determine the
presence of chlorine (Cl2) content in bulk rice. This study is descriptive in nature and involves
calculating positive (+) and negative (-) percentages. The research method employed for this study is
the Iodometric test. The research findings indicate that there are 3 samples containing the chemical
chlorine, but the chlorine levels in these samples do not exceed the Food and Drug Administration
(FDA) standards, or they are considered positive (+). Additionally, 16 samples do not contain chlorine
or are negative (-), accounting for 84.21% of the total samples. Therefore, it can be concluded that the
chlorine content in the 3 bulk rice samples is 15.79%, which does not exceed the FDA standards.
