ABSTRACT
Cultured fat is inducing adipose progenitor cells (APCs) to differentiate into mature adipocytes for consumption. The traditional adipogenic differentiation cocktail, including insulin, dexamethasone, indomethacin, isobutylmethylxanthine and rosiglitazone, has potential food safety problems in cultured fat. Therefore, the detection of these residues is necessary to ensure food safety. In this research, a method of high performance liquid chromatography (HPLC) was established to quantitatively analyze the potential residual content of dexamethasone, indomethacin, isobutylmethylxanthine and rosiglitazone in cultured fat and medium. Quantitative analysis showed that the content of four residues in cultured fat decreased to zero on Day 10. Subsequently, enzyme-linked immunosorbent assay (ELISA) was performed to detect the insulin content in the cultured fat and found that the insulin content in the cultured fat on Day 10 was 2.78 ± 0.21 µg/kg. After soaking with phosphate buffered saline (PBS), the insulin content decreased to 1.88 ± 0.54 µg/kg. In conclusion, this research provided an effective approach to clarify the content of potential residual components in cultured fat and it will provide reference for the safety of cultured fat in the future.
