Apples are one of the most widely consumed fruits, however they often times do not meet our expectations of being a crisp and juicy apple after we bite into them, thus leaving us disappointed with our purchase. This project aimed to help consumers purchase apples at peak freshness through numerous simple and cost-effective methods. We investigated significant physical changes of Royal Gala apples over the course of a month to observe a correlation between the numerous changes of the apples' components and time. We determined the aspects that make up a fresh apple and how they change as the apple ages through seven tests: the frequency made by the apple when coming into contact with an object, its conductivity, its crispness, its weight, its volume, its density, and its moisture content; we repeated these experiments until fairly consistent results were observed. Some of our graphs showed fluctuations in the data as the apples continued to age because we cannot be certain of the age of the apples, as we do not know the exact date of which they were taken out of storage and brought to the supermarket, but overall we did see a constant pattern in our results. These findings can then be employed by customers to better select fresh apples through physical observations and for supermarkets or agricultural enterprises to use our methods on sample sizes of an apple to determine its level of freshness, and better decide when to lower apple prices in order to prevent food waste.
