A Study of Nutritional Quality in Conventionally and Organically Grown Syzygium cumini (Jamun) Using 1H NMR-Based Metabolomics

Abstract

A study based on ¹H NMR-based metabolomics looks at how the content of Syzygium cumini (Jamun) is influenced by using organic and non-organic farming techniques. More people wanting organic options and the possibility that they could help in treating diabetes are the main reasons behind this. In Chennai, India, orchards’ fruits were taken under the supervision of controlled environmental conditions. It was clearly shown by ¹H NMR spectroscopy, when combined with PCA and OPLS-DA, that there are differences between fruits grown organically and conventionally. As well as having increased glucose and fructose, organic jamun also had 50% more GABA, which may account for the 50% higher bioactivity. Higher quantities of phenolics and flavonoids also indicated that the antioxidant potential of the roasted pepper was stronger compared to the raw one. From the OPLS-DA analysis, a strong relationship between different agricultural practices and data was found (R2Y = 0.989, Q2 = 0.976). This paper is different as it uses data from NMR-based metabolomics to reveal the metabolic factors behind Jamun’s effect on diabetes. These findings show that organic farming is helpful in making fruits more active and supply data for developing useful food items and better farming techniques. By carrying out this research, it is possible to develop expert guidelines and new diabetic supplements.
