Abstract

The study of local hawthorn fruits is of particular interest as they often contain high amounts of bioactive compounds. The objective of this research was to determine the physico-chemical characteristics of hawthorn ripened fruits, their color using CIELab system and their antioxidant capacity by DPPH method, based on scavenging 2,2-Di (4-tert-octylphenil)-1-picrylhydrazyl (DPPH) radicals. In addition, the content in mineral elements of hawthorn fruits was determined by Inductively Coupled Plasma Mass Spectrometer (ICP-MS). The result showed that hawthorn fruits have a pulp / kernel ratio of 1.44. The moisture, acidity, total soluble solids content, pH, pectic substances, protein, fat, ash, carbohydrates and energy values of hawthorn fruits were found as 69.14%, 0.47%, 22.20%, 5.96, 1.01%, 3.5%, 0.80%, 1.75%, 24.81% and 123.48 kcal/100g, respectively. Hawthorn fruits ripened (maturated) have a bright red color, an IC50 value of 53.47 mg/mL and contain high amounts of Ca (580.43 ppm), Mg (278.31 ppm) and Na (264.04 ppm). It is very important to evaluate the physico-chemical characteristics for the storage and processing of fresh fruits. This study revealed that hawthorn fruits from the local area should be considered a healthy product due to their bioactive compounds and are more suitable products than marmalade, jams, jelly, beverages and other food products.
