Development of Screen-Printed Electrode Biosensor for Rapid Determination of Triglyceride Content in Coconut Milk

الملخص EN

The screen-printed electrode biosensor was developed for triglyceride determination in coconut milk.

The biosensor was developed by adding lipase, glycerol-3-phosphate (GPO), and glycerol kinase (GK), which is immobilized to a gelatin solution.

The concentration of triglyceride is found to be linear to the current produced.

The developed screen-printed electrode biosensor showed the optimum response for pH 7.0, 45 mg amount of gelatin, 2.5% glutaraldehyde concentration solution.

The developed biosensor was able to find triolein concentrations 0.1 to 1.5 mM.

The correlation obtained between these two methods was 93% which was found to be good.
