Abstract

Objective: To make quantitative analysis of lard using UV Spectrophotometry. Method: UV Spectrophotometry techniques were carried out in order to determine the level of lard in pork nuggets. The extraction process was observed using n-hexane solvent and at temperature 55°C. Findings: The optimum wavelength was found to be at 270 nm. The lard concentration of five samples of pork nuggets was 24.9123%, 26.2719%, 26.8421%, 24.9123 and 24.5614% respectively. Novelty/Improvement: This work provides a simple method of investigating lard in pork nuggets.
