Abstract

This research explores the interplay between weight loss, color transformation, and total soluble solids (TSS) in Golden Delicious apples during storage at room temperature. Across six weeks, a freshly harvested batch of Golden Delicious apples underwent scrutiny in a controlled environment, maintaining around 24⁰C and 60% humidity. The study aimed to unravel the post-harvest physiological shifts in apples, explicitly focusing on factors affecting consumer appeal and shelf life. Methodologically, weight loss was precisely tracked using a high-precision scale, while color alterations were quantified via a portable colorimeter, yielding CIELAB L*, a*, and b* values. A refractometer was used to assess TSS, which indicated sweetness and ripeness. Correlation analysis revealed a strong link between weight loss and color shift, with a less pronounced yet significant connection between TSS and the other variables. These findings enrich our comprehension of the post-harvest dynamics of Golden Delicious apples, carrying implications for adequate storage and marketing tactics. This research supports the principles of the circular economy by enhancing the efficiency of post-harvest processes and minimizing waste through better storage practices. By understanding these factors, producers can reduce spoilage and extend the shelf life of apples, contributing to more sustainable food systems.
