The purpose of this study was to evaluate Pb, Cr, and Cd levels inside the Anadara granosa and to investigate the effect of submersion using Citrus aurantifolia (lime) and Orthosiphon aristatus (kidney tea leaves) solution on Pb, Cr, and Cd levels contained in the blood cockles taken from 10 markets in the city of Semarang, Central Java, Indonesia (Johar, Genuk, Gayamsari, Jati, Peterongan, Karangayu, Mangkang, Pedurungan, Boom Lama, and Ngaliyan). The concentration of heavy metals of Anadara granosa was analyzed using Atomic Absorption Spectrometer (AAS). Analysis of variance (ANOVA) showed that heavy metals (Pb, Cd, and Cr) of blood cockle taken from 10 markets provided no significant difference (P < 0.05) on the content of Pb, Cd and Cr. Purification was carried out using Citrus aurantifolia (lime) and Orthosiphon aristatus (kidney tea leaves) solution. The lowest Pb (0.00 mg kg–1) was obtained from Boom Lama and Peterongan market with purification using kidney tea leaves solution, while the lowest Cr [(0.30 ± 0.00) mg kg–1]) was obtained from Genuk market with lime solution. In addition, the lowest Cd (0.00 mg kg–1) was obtained from Boom Lama market with purification using kidney tea leaves solution. Accumulation of heavy metal contamination in blood cockle could affect the micronutrient status and consumer health.

Nusantara Bioscience 9: 385-391. Blood cockle (Anadara granosa) is a potential nutritious food with high economic value. This study aims at evaluating the level of zinc, calcium, protein, mercury, lead, and the sensorics quality of cireng (traditional Indonesian snack made from fried-tapioca flour dipped into sauces) supplemented with blood cockle. This study used complete randomised design, where the treatment factors consisted of flour made from blood cockles to supplement the flour used in making the cireng snacks. The concentration of the treatment factors were 0%, 5%, 10%, 15%, and 20%. The data were analyzed using the One Way ANOVA test and LSD test. This study shows that blood cockles’ supplementation significantly increases the level of protein (p=0.05), zinc (p=0.031), calcium (p= 0.016), lead (0.000), mercury (p= 0.022) of the cireng snacks. Supplementation of blood cockles has increased the preference toward cireng’s flavor, aroma, and color by 10%, whereas the level of preference toward the texture of cireng which used the blood cockle has increased by 20% compared to cireng product with non-supplemented flour. The level of lead (Pb), and Mercury (Hg) are below the Indonesian National Standard (SNI). Supplementation of blood cockles from Gorontalo in the flour used in making the cireng snacks produced snacks with a better nutrition value and safe to consume. Also, the flavor, color, texture, and aroma are acceptable.
