Abstract:
In this paper, five brands of edible bird's nest were tested for their nutrients composition and hazard factors. The nutrient composition included water content, ash content, protein content, fat content, total sugar content, sialic acid content, amino acid composition and content, and conventional element composition and content. The hazard factors included the type and content of heavy metal elements and the content of nitrite. Results showed that the water content of the five brands of edible bird's nest was 14.05%~15.21%, the ash content was 3.38%~4.91%, the protein content was 66.61%~67.97%, the fat content was 0.15%~0.21%, the total sugar content was 17.12%~25.47%, the sialic acid content was 12.21%~12.82%, and the total amino acid content was 57.80%~61.40%. The major elements Na, Mg and Ca were detected in bird's nest. The results of the hazard factors determination were that the heavy metal elements Hg and As were not detected in edible bird's nest. The contents of Zn, Cr, Cd and Pb did not exceed 1.15 μg/g in the five brands of edible bird nests. The content of nitrite was 11.38 mg/kg~14.89 mg/kg. Based on the determination of basic nutrients and hazard factors in bird's nest and the relevant reference data, it could provide a scientific basis for the establishment of quality evaluation standards and supervision program for bird's nest.
