Abstract

Lorjuk (solen sp.) represents one type of capable shellfish of adsorbing lead (Pb). Some research results show that processed foods from shellfish still contain heavy metals. On the other hand, the analysis of Pb content in processed food lorjuk has never been reported. The purpose of this study is to analyze the lead (Pb) in a variety of processed foods lorjuk, Such as lorjuk beans, rengginang lorjuk, and also lorjuk crispy on various brands. This research was conducted in four stages, namely (1) Preparation (2) Destruction (3) Testing (4) Calculation of Pb content (mg / Kg). Initially, the sample is mashed and then dried in an oven at 70oC until the weight is constant. The result is wet destruction with the oxidizing agent nitric acid (HNO3 p.a). Destruction samples were further diluted with 0.5 M HNO3 and lead content (Pb) measured by atomic absorption spectroscopy. The results showed that all samples, both lorjuk beans, rengginang lorjuk, and lorjuk crispy contained heavy lead metals (Pb). Lorjuk beans with the brand c have the highest heavy metal content of 1.733 mg / Kg, while the sample with the lowest Pb content is the lorjuk crispy sample which is 0.058 mg/Kg (brands g and i). The average Pb metal content in lorjuk rengginang and lorjuk crispy is still below the threshold following SNI 7387: 2009, while the Pb metal content in lorjuk nuts has exceeded the permitted threshold.
