    Antioxidant and Textural Properties and Aroma and Fatty Acid Profile of Meatless Cig Kofte, a Special Food in Turkey, Produced by Industrial Processing
    (Blackwell Publishing Ltd, 2016) Ozturk, I.; Karaman, S.; Tastemur, B.; Tornuk, F.; Sagdic, O.; Kayacıer, Ahmed
    In this study, 10 cig kofte samples collected from different producers were analyzed. Dry matter, pH and water activity values were in the range of 34.13-53.40%, 4.67-5.03 and 0.934-0.967, respectively. Major fatty acids were determined to be oleic and linoleic acid, and the samples showed similar fatty acid profiles. Linoleic acid was the most abundant fatty acid and its level was in the range of 0.94-54.13% in the samples. Textural parameter magnitudes of the samples, except for one, were determined to be close to each other. A total of 44 volatile compounds were determined in the samples and the major ones were limonene and gamma terpinene. Total phenolic contents of the samples were determined to be in the range of 56-132.1mg gallic acid equivalent/g dry extract. In conclusion, variable properties were observed in the retailed meatless cig kofte samples sold in Turkey. © 2016 Wiley Periodicals, Inc.

    INVESTIGATION ON PHYTOCHEMICAL, ANTIOXIDANT, AND ANTIMICROBIAL PROPERTIES, DRYING PROFILE AND EXTRACTION OPTIMIZATION OF DEER APPLE (MALUS TRILOBATA V ERIOLOBUS TRILOBATUS)
    (Plapiqui(Uns-Conicet), 2022) Demircan, H.; Sagdic, O.; Ozkan, K.; Kayacan, S.; Us, A. A.; Sarioglu, K.; Oral, R. A.
    In this study, drying kinetics, extraction optimization, total phenolic and flavonoid contents, antioxidant activities, and antimicrobial effects of deer apple (Malus trilobata v Eriolobus trilobatus) fruit species were determined. Representing 50% ethanol and 15.86 solvent-sample ratio; total phenolic and flavonoid content, antioxidant activity by DPPH and CUPRAC methods, and inhibition percent were found as 1000.9 mg gallic acid equivalent/kg fresh weight (FW), 469.5 mg catechin equivalent/kg FW, 967.7 mg Trolox equivalent/kg FW, 3.58 mg Trolox equivalent/g FW, 39.85%, respectively. It is shown that the deer apple fruit has antimicrobial activity against Escherichia coli O157:H7, Staphylococcus aureus, Bacillus cereus, and Aspergillus flavus that known as pathogenic or spoilage microorganisms. This study shows that deer apple fruit is a good source of phenolic and flavonoid and has antimicrobial activity. Also, it contributes information about some physicochemical and antimicrobial properties of deer apple fruit and aims to increase the awareness of this fruit species.
