This study aimed to determine the differences in the content of vitamin C in pineapple fruit and chips. The analytical method used to determine vitamin C levels is UV-Vis Spectrophotometry because this method is quite accurate and more efficient and produces high accuracy and precision. The results of this study are the linearity test obtained a linear regression equation, namely y = 0.0363x + 0.0687 with a value of R² = 0.993. Successively obtained the average level of pineapple fruit is 0.191 %w/w, brand A pineapple chip is 0.099 %w/w, and pineapple chips brand B is 0.111 %w/w.
