Comparing Ascorbic Acid Content between Organic and Non-organic Malus domestica

CSEF · 2014 Biochemistry/ Molecular Biology

Noah K. Chow, Meghan M. Lorenz · Thousand Oaks High School, Thousand Oaks, Ventura County

Overview

Objectives/Goals The objective is to determine if there is more ascorbic Acid (vitamin C) in organic or non-organic Malus Domestica (apples). Methods/Materials Five different types of apples were collected. The peel and pulp of the samples were run through a High Performance Liquid Chromatography machine (HPLC). The ascorbic acid content was determined by comparing the amounts found in the standards and samples. Results There was more vitamin C found in the organic apple peel samples than the non-organic. However in the pulp samples there was not a significant change in vitamin C content. Conclusions/Discussion The results we obtained showed that organic Malus Domestica have higher ascorbic acid levels compared to the non-organic.

Summary statement

Comparison of vitamin C content in apples.
