Exploring the relationship between blueberry size and antioxidant content

Abstract Blueberries are a widely consumed superfood, known for their potent phytochemical content and health benefits. Given their importance to the global food market and the current health culture, blueberries are the focal point of much inquiry into their composition, physiological benefits, and the effect of growing conditions on the quality of the final berry. Given their complex nature and the numerous factors involved in the growing and production of blueberries, there are many variables to consider when determining the chemical characteristics of blueberry samples. One important factor to control is the berry size, which, if left uncontrolled, may confound the objective information sought within the study. This communication, which utilizes HPLC and in-column derivatization for the analysis of antioxidants, shows the impact of berry size (mass/volume) on the antioxidant content and that once the size of a blueberry is controlled, sample-to-sample variations become minimized.
