Publication Development of purple basil (Ocimum basilicum L.) sherbet fortified with propolis extract using response surface methodology(Springer, 2021-07-03) Karabacak, Azime Özkan; Özoğlu, Özüm; Durgut, Senanur; Bağatırlar, Sina Recep; Kaçar, Oya; Tamer, Canan Ece; Korukluoğlu, Mihriban; ÖZKAN KARABACAK, AZİME; ÖZOĞLU, ÖZÜM; Durgut, Senanur; Bağatırlar, Sina Recep; KAÇAR, OYA; TAMER, CANAN ECE; KORUKLUOĞLU, MİHRİBAN; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Gıda Mühendisliği Bölümü.; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Tarla Bitkileri Bölümü.; 0000-0003-4175-4477; 0000-0002-1314-4965; 0000-0003-3600-142X; AAH-2319-2019; AAG-8503-2021; IVU-8132-2023; JOF-0451-2023; CFB-4587-2022; FFT-5849-2022; J-5125-2018The aim of this study was to develop a novel purple basil sherbet fortified with propolis extract. The levels of the purple basil (Ocimum basilicum L.) aerial parts (leaves, flowers and stems) (200-300 g/L), propolis extract (48-72 mg/100 mL) and infusion time (30-40 min) on total phenolic content (TPC), antioxidant activity (FRAP, DPPH, CUPRAC methods), color parameters (L*, a*, b*, C*, h degrees) and sensory properties were investigated by using Box-Behnken design. According to the model, the optimized values for the propolis extract concentration, purple basil concentration and infusion time were 58.66 mg/100 mL, 300 g/L and 40 min, respectively. Moreover, antimicrobial activity of the beverage samples against Bacillus subtilis, Escherichia coli, Salmonella Enteritidis, Lactiplantibacillus plantarum, Saccharomyces cerevisiae, Schizosaccharomyces pombe, Aspergillus niger and Penicillium roqueforti was also determined.Publication Research of antifungal effects on some essential oils with tube dilution(Univ Estadual Londrina, 2021-01-01) Çolak Şaşmazer, Rükiye; Korukluoğlu, Mihriban; Çolak Şaşmazer, Rükiye; KORUKLUOĞLU, MİHRİBAN; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Gıda Mühendisliği Bölümü; 0000-0002-1828-1205; CKX-5200-2022; J-5125-2018The aim of study to investigate inhibition effects of cinnamic acid (volatile compound of cinnamon), limonene (essential oil of lemon) and eugenol (essential oil of clove, cinnamon) on Metschnikowia fructicola, Candida oleophila, Schisosaccharomyces pombe, Saccharomyces uvarum and Kloeckera apiculata. In this study, tube dilution method was used. Among eugenol, limonene and cinnamic acid, it was found that cinnamic acid has the most inhibition effect with low concentrations (%2.8, %3.84, %4.36, %5,4) at tube dilution methods. Also it was found that test yeast have different resistance against test materials.Publication A comparative study about antioxidant activity and phenolic composition of cumin (Cuminum cyminum L.) and coriander (Coriandrum sativum L.)(Natl Inst Science Communication-niscair, 2020-04-01) Demir, Sema; Korukluoğlu, Mihriban; Demir, Sema; KORUKLUOĞLU, MİHRİBAN; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Gıda Mühendisliği; 0000-0003-2610-7466; AAF-7912-2021; AAA-2428-2021Apiaceae (Umbelliferae) is a large family which involves approximately 455 genus and 3600 species. Coriander (C. sativum L.) and cumin (C. cyminum L.) are two members of Apiaceae family which commonly used for medicinal purpose due to their antioxidant activity. Since the antioxidants are compounds that prevent the oxidation by neutralizing free radicals, researches about their potential utilizations are of great interest for food science and technology. Due to the consumer preference and the worries about synthetic antioxidant compounds, the food industry shows tendency to use natural antioxidant compounds obtained from plant materials. FDA has recognized more than 150 plants as GRAS, without no limitations intake. Coriander, cumin, anise, fennel, thyme and oregano are some plants found in this list. The focus of this research is to contrast the composition of phenolic profile and antioxidant activity of ethanolic and methanolic extracts of these two medicinal herbs belonging to the Apiaceae family. For this purpose, coriander and cumin were analyzed for phenolic compounds and antioxidant assay. Antioxidant assay analyses were performed by applying cupric reducing antioxidant capacity (CUPRAC), 2,2'-azino-bis3-ethylbenzothiazoline-6-sulphonic acid (ABTS), ferric reducing antioxidant power (FRAP), 1,1-diphenyl-2-picrylhydrazyl methods (DPPH).Publication The impact of different commercial probiotic cultures with starters on technological, physicochemical and sensorial properties of a traditional yogurt-based appetizer "Cacik"(Croatian Dairy Union, 2019-07-01) Altuntaş, Seda; Korukluoğlu, Mihriban; KORUKLUOĞLU, MİHRİBAN; Bursa Uludağ Üniversitesi/Ziraat Fakültesi/Gıda Mühendisliği Bölümü.; J-5125-2018The selection of proper probiotic culture is essential for maintaining adequate numbers of viable cells until consumption since potential adverse interaction between selected strain and starter culture. This study examined the suitability of Cacik as a potential probiotic carrier including Lactobacillus acidophilus 74-2, Lactobacillus rhamnosus Howaru HN001 (TM) and Bifidobacterium longum BB536 in different combinations. The presence of three probiotic strains caused higher post acidification and shorter fermentation time associated to higher counts of L. bulgaricus. Except for certain combinations containing B. longum BB536, the counts of individual probiotic bacteria were higher than 6 log g(-1) for all probiotic supplemented Cacik samples. Results showed that bacterial interaction was decisive for survival over 21 days of storage. Probiotic products containing only B. longum BB536 or B. longum BB536 with L. acidophilus 74-2 did not accomplish in terms of the technological point, since the viable cell counts decerased for 2.45 log and 1.95 log per g, respecitevly, throughout the storage period. In three of totally four combinations included L. rhamnosus Howaru HN001 (TM) alone or combined with other probiotic bacteria, the viable cell counts of L. rhamnosus Howaru HN001 (TM) remained at the inoculated level, while the counts significantly increased in co-culture with L acidophilus 74-2. Considering the overall sensorial attributes and survival of probiotics, Caclk supplemented with L. rhamnosus Howaru HN001 (TM) alone, combinations of B. longum BB536 and L. rhamnosus Howaru HN001 (TM) or L. acidophilus 74-2 and L. rhamnosus Howaru HN001 (TM) or by all of the three tested probiotics, were suggested as suitable for further production.
