Kırklareli Bölgesinden Toplanan Peteklerde Pestisit Ve Antibiyotik Kalıntısı Aranması
Kurultay, Şefik; Velioğlu, Hasan Murat; Sağlam, Özgür (Namık Kemal Üniversitesi, 2016)2012 FAO verilerine göre yıllık 88162 tonluk bal üretimi ile Türkiye Çin’den sonra dünyanın en büyük ikinci bal üreticisi konumundadır. Ancak ülkemizde arıcılık halen atadan kalma yöntemlerle yapıldığından kovan başına bal ... -
Low-fat beef patties with cold-pressed oils optimized by mixture design
Velioğlu, Hasan Murat (Vup Food Research Inst, Bratislava, 2016)Partial animal fat replacement by cold-pressed grape seed oil (GSO) and pomegranate seed oil (PSO) on low-fat beef patties was studied using simplex-centroid mixture design. Linear and quadratic model equations were developed ... -
A novel method for discrimination of beef and horsemeat using Raman spectroscopy
Boyacı, İsmail Hakkı; Temiz, Havva Tumay; Uysal, Reyhan Selin; Velioğlu, Hasan Murat; Yadegari, Reza Jafarzadeh; Rishkan, Mojtaba Mahmoudi (Elsevier Sci Ltd, 2014)A new approach, based on the usage of Raman spectroscopy in combination with chemometrics, was developed for the rapid determination of beef adulteration with horsemeat. The data mining process of collected Raman spectra ... -
Protein based evaluation of meat species by using laser induced breakdown spectroscopy
Sezer, Banu; Bjelak, Armin; Velioğlu, Hasan Murat; Boyacı, İsmail Hakkı (Elsevier Sci Ltd, 2021)Meat adulteration through partial substitution with cheaper species or mislabeling causes significant problems in terms of health, religious beliefs, economy, and product quality. Therefore, identification of meat species ... -
Raman Spectroscopic Barcode Use for Differentiation of Vegetable Oils and Determination of Their Major Fatty Acid Composition
Duraklı Velioğlu, Serap; Ercioğlu, Elif; Tümay Temiz, Havva; Velioğlu, Hasan Murat; Topçu, Ali; Boyacı, İsmail Hakkı (Wiley, 2016)In this study, differentiation of vegetable oils and determination of their major fatty acid (FA) composition were performed using Raman spectral barcoding approach. Samples from seven different sources (sunflower, corn, ... -
A rapid method for determination of the origin of meat and meat products based on the extracted fat spectra by using of Raman spectroscopy and chemometric method

A total of 132 ... -
Saccharomyces cerevisiae kaynaklı invertaz enzimi üretimine ultrasonikasyon parametrelerinin etkisinin araştırılması
Oral, Sabriye Bükre (Tekirdağ Namık Kemal Üniversitesi, 2021)İnvertaz enzimi bilimsel dilde ß-fruktofuranozidaz ya da sükraz olarak bilinmektedir. Hidrolaz sınıfına ait olan bu enzim kaynak olarak hayvan, bitki ya da mikroorganizmalardan yararlanılarak elde edilebilmektedir. İnvertaz ... -
The use of Raman spectroscopy and chemometrics for the discrimination of lab-produced, commercial, and adulterated cold-pressed oils
Tümay Temiz, Havva; Duraklı Velioğlu, Serap; Gürbüz Güner, Kadir; Velioğlu, Hasan Murat (Elsevier, 2021)In this study, lab-produced cold-pressed oil samples of black cumin (CPBCO), almond (CPAO), and walnut (CPWO) were compared with their commercial substitutes. Additionally, adulteration of cold-pressed oils with corn and ... -
