Assessment of Sugar and Mineral Components in Taif Pomegranate Granules Using Spectral and Microanalytical Analyses

Abstract

For the first time this article was focused on the use of spectral and microanalytical tests to investigate the sugar and mineral contents in Taif Pomegranate Granule Ingredients (TPGIs). Deionized water was used to extract “trace elements” and “sugars” via an ultrasonic bath as well as the chemical composition of the Taif pomegranate fruit granules was studied and discussed in terms of dry weight. The functional groups of sugars, carbohydrates and kind of mineral salts were identified using the analytical techniques such as scanning electron microscopy (SEM), infrared spectroscopy (FTIR), "High-Performance liquid chromatography" (HPLC) system equipped with a "Sugar Pak-1" column, atomic absorption equipment and flame photometry. The optimal conditions were studied for several factors (column temperature, mobile phase types, mobile phase flow rate and injection loop size). The results of the analyzes conducted demonstrated that the components of Taif pomegranate granules (TPGIs) contained sugars (such as fructose, glucose, and sucrose), some essential elements (selenium, sodium, potassium, calcium, magnesium, and iron) and chlorine ions. The components of TPGI are an important source of many nutrients that are rich in monosaccharides, antioxidants and flavonoids and can contribute to a healthy diet.
