Studies on the Determination of Formaldehyde in Squid and Bummalo

Abstract

Abstract. The paper tends to study the determination of formaldehyde in squid and bummalo by HPLC. The calibration curve in the 0.5-50.0 µg/mL range was obtained and correlation coefficient was 0.9993. The detection limit was 5 mg/kg. Endogenous formaldehyde in bummalo and squid as well as the change rule of formaldehyde under the frozen storage condition was assessed. Results showed that the formaldehyde content in bummalo was higher than the squid. Under the same storage conditions, formaldehyde content both in bummalo and squid were significantly increased in pace with frozen storage time. Therefore, inspection agencies should indicate the sampling time and testing time, when they detect the formaldehyde content in aquatic products.

Mathematical Formulation to Differentiate between Naturally Occurred and Artificially Added Formaldehyde in the Ice Stored of Lizardfish (Saurida tumbil)

“…The concentration of natural formaldehyde in fish varies depend on the species, characteristics of the fish, and the environment (Zhang et al, 2017). Several types of fresh fish had a high natural formaldehyde content, such as opah fish/Lampris guttatus (Barokah et al, 2020), nomei (Harpodon nehereus) (Jaman et al, 2015;Shen et al, 2015), beloso (Saurida tumbil) (Anissah et al, 2019;Nurhayati et al, 2019) and squid (Loligo sp.)…”

Development of electrochemical biosensor based on CNT–Fe3O4 nanocomposite to determine formaldehyde adulteration in orange juice

“…US Food and Drug Administration (USFDA) identifies formaldehyde for use only as a component of adhesives and does not recommend its use in human food (Wahed et al 2016). For the quantitative analysis of formaldehyde in samples, various existing techniques such as HPLC (Jeong et al 2015), gas chromatography (Zhang et al 2015) and chemiluminescence (Khataee et al 2016) are used in laboratory. As established, most of these chemical methods are long, expensive, laborious and require skilled personnel to carry out the testing and run the instrumentation.…”
