Density-based Food Analysis Using a Smartphone
Density-based Food Analysis Using a Smartphone
Density is a crucial factor of interest in the food industry because it can reveal valuable information aboutthe content and quality of food products. Traditionally, this physical property is quantified using ahydrometer or a pyncometer. However, the accuracy of analog instruments is limited by human error andmore modern digital adaptations of such methods come with high monetary costs. Here, we present a low-cost, portable, and user-friendly platform for density-based analysis of liquid food samples of very smallvolumes (
