Abstract

The experiment to measure starch concentration is a means to introduce of the concept of the standard curve in quantitative analytical chemistry. The mass balance gives a likely upper limit for the starch content of the entire potato using certain assumptions. If a sufficiently precise and accurate means of determining the density of the potato is available, the relationship between yield and recovery could be examined further using an established correlation between potato density and starch content.
