    In Vitro Assessment of Food-Derived Bioaccessibility and Bioavailability in Bicameral Cell Culture System
    (Türk Biyokimya Derneği, 2020) Özel Taşcı, Cansu; Pilatin, Gözde; Edeer, Özgür; Güleç, Şükrü
    Background: Functional foods can help prevent metabolic diseases, and it is essential to evaluate functional characteristics of foods through in vitro and in vivo experimental approaches. Objective: We aimed to use the bicameral cell culture system combined with the in vitro digestion to evaluate glucose bioavailability. Materials and methods: Cake, almond paste, and pudding were modified by adding fiber and replacing sugar with sweeteners and polyols. Digestion process was modeled in test tubes. Rat enterocyte cells (IEC-6) were grown in a bicameral cell culture system to mimic the physiological characteristics of the human intestine. The glucose bioaccessibility and cellular glucose efflux were measured by glucose oxidase assay. Results and discussion: The glucose bioaccessibilities of modified foods were significantly lower (cake: 2.6 fold, almond paste: 9.2 fold, pudding 2.8 fold) than the controls. Cellular glucose effluxes also decreased in the modified cake, almond paste, and pudding by 2.2, 4, and 2 fold respectively compared to their controls. Conclusion: Our results suggest that combining in vitro enzymatic digestion with cell culture studies can be a practical way to test in vitro glucose bioaccessibility and bioavailability in functional food development.

    Usage of Rice Milk in Probiotic Yoghurt Production
    (North University of Baia Mare, 2016) Uzuner, Aydın Erdem; Kınık, Özer; Korel, Figen; Yıldız, Gamze; Yerlikaya, Oktay
    There are previous studies focusing on the production of probiotic and fermented dairy products made using vegetable based raw materials like oats and soy, however there is a limited number of studies on the usage of rice milk in fermented dairy products. Four different types of yoghurt samples were produced and stored for 21 days at 4°C. Physical, chemical, microbiological and sensory characteristics of the samples were performed at the 1st, 7th, 14th and 21st days of the storage. It was determined that rice milk increased the viscosity values but decreased the values of the texture, whey separation and the chemical and microbiological properties of yoghurts. Acetaldehyde, acetoin, acetone and diacetyl of carbonyl compounds were detected as main flavor components of yoghurt samples. In the sensory analysis, scores decreased as the rice milk proportions in yoghurt was increased and the panelists reported that P1 sample (25% rice milk + 75% cow's milk) was the closest sample to the control sample (100% cow's milk). Generally speaking, samples containing rice milk did not give good results. However, P1 samples were the most favored products among the samples containing rice milk as they were the closest product to the control group. The consumption of such products is continuously increasing as the customers' tendency to consider them as functional products rather than traditional food products increase.
