    Influence of Tapioca, Corn, and Potato Starches on Physical and Textural Characteristics of Puffed Starch Crackers
    (Sidas Medya A.S., 2025) Cankal, Y.S.; Berk, B.; Koroglu, E.; Yorulmaz, H.; Çavdaroglu, E.; Unluturk, S.
    Puffed products have become increasingly popular, prompting this study to determine how various types of starches such as tapioca, potato, and corn influence the physical, textural, and microstructural properties of starch-based puffed crackers. The physicochemical properties of the starches, including amylose content, water holding capacity (WHC), and oil holding capacity (OHC), as well as the physical properties, texture, and microstructure of the resulting crackers were evaluated. Results indicated that all starches had similar WHC and OHC values. Crackers made with corn starch (FCS) had the lowest oil content (8.65%) and the highest rehydration ratio (1.12). After frying, tapioca and potato starches produced significantly crispier crackers compared to corn starch, with a strong positive correlation (r=0.986) between crispiness and volume expansion. Potato starch-based crackers (FPS) exhibited longer cooling periods due to lower specific heat capacity. Scanning electron microscopy (SEM) images revealed that tapioca starch caused more pronounced changes in microstructure due to its porosity, which explained differences in volume expansion and texture. The study highlighted how different starch sources impacted the texture and microstructure of puffed crackers, providing insights for producing crackers with desired properties. © 2025 Sidas Medya A.S..

    Use of Magic Sandwich Echo and Fast Field Cycling Nmr Relaxometry on Honey Adulteration With Corn Syrup
    (John Wiley and Sons Ltd, 2022) Berk, B.; Cavdaroglu, C.; Grunin, L.; Ardelean, I.; Kruk, D.; Mazi, B.G.; Oztop, M.H.
    BACKGROUND: Adulteration is defined as the intentional addition of a material that is not a part of the nature. In this study, a non-conventional time domain nuclear magnetic resonance (TD-NMR) pulse sequence: magic sandwich echo (MSE) was used to detect the adulteration of honey by glucose syrup (GS) and high fructose corn syrup (HFCS) accompanied with T1 and T2 relaxation times. Also, fast field cycling NMR (FFC-NMR) relaxometry and multivariate analysis were performed to investigate the adulteration. RESULTS: Higher maltose in GS and changing glucose to water ratio of HFCS gave high correlation with the crystal content values. In HFCS adulteration, two separate populations of protons having different T2 values were detected and T1 times were also used to determine GS adulteration. Addition of GS increased T1 while addition of HFCS increased T2, significantly. CONCLUSION: The results showed that it is possible to differentiate the unadulterated and adulterated honey samples by using TD-NMR relaxation times and crystal content values obtained by the MSE sequence. By FFC-NMR relaxometry, not only GS addition but also the amount of GS was examined. The multivariate analysis technique of principal component analysis was able to distinguish the types of adulterants. © 2021 Society of Chemical Industry. © 2021 Society of Chemical Industry.
