    Deer apple (Malus trilobata) fruit grown in the Mediterranean region: identification of some components and pomological features
    (Soc Brasileira Ciencia Tecnologia Alimentos, 2022) Demircan, Huseyin; Sarioglu, Kemal; Sagdic, Osman; Ozkan, Kubra; Kayacan, Selma; Us, Ahmet Abdullah; Oral, Rasim Alper
    Deer apple (Malus trilobata) fruit is present naturally in the Mediterranean region and can be used for many different purposes, such as consuming as fresh and dried fruits, using as herbal tea flavorings, making vinegar, and pickle. Also, it is traditionally used against various health problems like cholesterol, shortness of breath, diabetes, and hypertension. Many researchers have studied some properties of deer apple fruit, such as the ecology of the species, fruit and seed properties, body form, and phenology. In this study, besides pomological properties, the organic acid, phenolic compound, sugar, and aroma composition of the deer apple fruit were determined for the first time. Malic acid (27.5 mg/g) is the most abundant organic acid in deer apple, while fructose (351 mg/g) is the most abundant sugar. It was determined that the deer apple contains various phenolic compounds such as protocatechuic acid, chlorogenic acid, caffeic acid, epicatechin, rutin, and quercetin. Acetic acid, nonanal, hexanal, acetoin, acetaldehyde, n-octanal, hept-2(E)-enal are the most abundant aroma compounds.

    Fabrication and Characterization of Calcium Alginate Beads with a Specially Designed Magnetic Pulse Encapsulator
    (Wiley-V C H Verlag Gmbh, 2025) Demircan, Seyda; Demircan, Huseyin; Sarioglu, Kemal; Ates, Ergun; Seyhun, Nadide; Oral, Rasim Alper
    In this study, a novel encapsulator system based on magnetic field principles was developed to produce gallic acid-loaded beads with an adjustable particle size and high production capacity. A dripping device was designed and optimized using the response surface methodology with a central composite design. Alginate concentration, nozzle diameter, frequency, distance, and flow rate were selected as independent variables. Bead properties, including encapsulation efficiency, production yield, loading capacity, particle diameter, aspect ratio, circularity, sphericity, polydispersity index, span, D10, D50, and D90, values were evaluated as response variables. In vitro release kinetics of the beads were investigated. Particle shape was mainly affected by all parameters except flow rate, while size distribution was predominantly governed by the alginate concentration, nozzle diameter, and frequency. Bead morphology strongly affected the release behavior, with smaller and more spherical beads showing faster release rates. The developed system successfully produced small-sized beads with high encapsulation efficiency (up to 60.7%). These findings demonstrate the potential of the proposed magnetic encapsulation system for the efficient encapsulation of gallic acid and other water-soluble phenolic compounds. Furthermore, its adaptability to multi- or interchangeable nozzle configurations makes it suitable for pilot- or industrial-scale production.
