Abstract

Gadung tubers or Dioscorea hispida are tubers that originally grew in the forest and are used as alternative food ingredients to replace rice and corn. One of the preparations from gadung tubers that is popular with the community is gadung tuber crackers. Before being processed into food, gadung tubers must be processed properly so that the cyanide content is reduced. Cyanide is a goitrogenic substance that is naturally found in foodstuffs. The purpose of this study was to determine the cyanide content in gadung root crackers. In this study, 3 samples were sold in Pelem Village, Tulungagung Regency. Cyanide analysis was carried out by qualitative test using picrate paper and quantitative test using complex formation titration. The cyanide content in the sample was 2.124 mg/kg; 0.9 mg/kg; 1,386 mg/kg.

Abstract

Formaldehyde, better known as formalin, is a prohibited food additive. The use of formalin in food can cause poisoning in the human body, namely acute abdominal pain accompanied by vomiting, the emergence of nervous system depression or circulatory failure. The purpose of this study was to identify the formalin content in shrimp tested at the KIPM Surabaya I Center. This study was conducted using a test kit method, namely formalin main reagent. The principle is to add liquid (reagent) to food suspected of containing formalin. The reaction between chromatophore acid and formalin produces a purple complex compound of 3,4,5,6-dibenzoxanthylium . The results of this study showed that negative shrimp samples contained formalin, indicated by the absence of color changes in the samples analyzed and compared with the positive controls that had been made.
