Book Part Applications of Light-Emitting Diodes in Liquid Foods(Apple Academic Press, 2025) Cankal, Y.S.; Ünlütürk, S.Recently, there has been increased interest in investigating alternative nonthermal processes to maintain the quality of liquid food products while preserving their nutritional value. Ultraviolet (UV) irradiation technology is one such method and has been widely explored for liquid food products. Low or medium-pressure mercury vapor lamps are used in this technology. Since these lamps contain mercury known to have toxic effects on the human body and the environment [18], the use of light-emitting diodes (LEDs) has become prominent as an ultraviolet light source. LEDs are created using non-toxic semiconductor material, which allows emitting in different wavelengths. Recently, Light Emitting Diode (LED) technology has been emerging as a non-thermal and non-chemical treatment for surface disinfection and preservation of solid and liquid food materials. This chapter emphasizes the application and effectiveness of LEDs of different wavelengths in liquid food processing and storage. © 2025 by Apple Academic Press, Inc.Book Part Citation - Scopus: 3Tomato: Genetics, Genomics, and Breeding of Health-Related Traits(Springer Nature, 2023) Çelik,I.; Gürbüz Çolak,N.; Doğanlar,S.; Frary,A.Tomato (Solanum lycopersicum) is a popular crop due to its versatility and nutritional quality. In addition to its nutritional content, tomato is rich in various phytochemicals that are known to have beneficial effects on human health. These bioactive components include pigments like lycopene and Β-carotene, ascorbic acid (vitamin C), phenolic compounds, polyamines, and glycoalkaloids. Tomato metabolites have various bioactivities such as antihypertensive, antioxidant, anticancer, anti-inflammatory, antidiabetic, antiallergenic, antiatherogenic, antithrombotic, and antimicrobial effects. Research aimed at improving tomato for many of these specific activities is still in its infancy; however, a foundation of knowledge has been established for health-related (HR) traits in the crop. In this chapter, previous works surveying tomato germplasm for HR traits, conventional breeding, and genetic investigation of these characteristics are described. We also discuss research aimed at HR gene mapping and isolation as well as efforts to improve these traits via genetic engineering and genome editing. © Springer Nature Singapore Pte Ltd. 2023.Article Citation - WoS: 2Citation - Scopus: 6Immobilization of Olive Leaf Extract With Chitosan Nanoparticles as an Adjunct To Enhance Cytotoxicity(American Chemical Society, 2023) Özdamar, Burcu; Sürmeli, Yusuf; Şanlı Mohamed, GülşahWe immobilized the olive leaf extract (OLE) with chitosannanoparticles(CNPs) by optimizing the effect of various immobilization conditions,and OLE-loaded CNPs (OLE-CNPs) were then elaborately characterizedphysicochemically by scanning electron microscopy (SEM), Fourier transforminfrared (FT-IR) spectroscopy, dynamic light scattering (DLS), andatomic force microscopy (AFM). Under optimal conditions, CNPs wereable to accommodate the OLE with a loading capacity of 97.5%. Theresulting OLE-CNPs had a spherical morphology, and their average diameterwas approximately 100 nm. The cytotoxic influence, cell cycle distribution,and apoptosis stage of OLE and OLE-CNPs were analyzed on lung carcinoma(A549) and breast adenocarcinoma (MCF-7) cell lines. In an in vitrocytotoxic assay, IC50 values of OLE-CNPs were determinedto be 540 & mu;g/mL for A549 and 810 & mu;g/mL for MCF-7. Thetreatment of both A549 and MCF-7 with OLE-CNPs caused the highestcell arrest in G0/G1 in a dose-independent manner. OLE-CNPs affectedcell cycle distribution in a manner different from free OLE treatmentin both cancer cells. A549 and MCF-7 cells were predominantly foundin the late apoptosis and necrosis phases, respectively, upon treatmentof 1000 & mu;M OLE-CNPs. Our results suggest that CNPs enhance theutility of OLEs as nutraceuticals in cancer and that OLE-CNPs canbe utilized as an adjunct to cancer therapy.Conference Object Citation - WoS: 14Citation - Scopus: 16Drying of Olive Leaves in a Geothermal Dryer and Determination of Quality Parameters of Dried Product(Elsevier, 2019) Helvacı, Hüseyin Utku; Menon, Abhay; Aydemir, Levent Yurdaer; Korel, Figen; Gökçen Akkurt, GüldenIn this study, a cabinet type geothermal dryer was designed, operated and tested for drying olive leaves with minimum losses of phenolic content and antioxidant capacity by optimization of drying conditions. Two factors; face centered central composite design was applied and response surface methodology was used to optimize the drying conditions of olive leaves. The results indicate that phenolic content stability were mainly affected by air temperature, whereas antioxidant capacity is affected by both air temperature and velocity (p<0.05). The optimal drying conditions were found to be at 50°C of air temperature and 1 m/s of air velocity for the minimum losses of determined quality parameters, where 88.8% of phenolic content and 95.3% of antioxidant capacity were recovered.
