People who underwent surgery or suffer from dysphagia disease cannot consume solid food materials. Liquid food formulations which are called as enteral feeding formulations are prepared for these people. The main objective...
Effect of gelatinization properties of different starch types in the presence of psyllium fiber on in vitro digestion
Sevilmiş, Başak; Şensoy, İlkay; Department of Food Engineering (2021-2-12)
Starch’s digestibilityin foods strongly depends on the structure, other ingredients,and processing conditions used. It is essentialto understand the relationship between food matrix and starch digestibility. Theaim...
Changes in the structure and digestion fractions of wheat starch cooked with and without fiber
Ataç, Leyla Elif; Şensoy, İlkay; Department of Food Engineering (2021-2-10)
Starch digestibility affects blood glucose levels. Dietary fibers had been shown to slow down starch digestibility. Therefore, the objective was to understand the effect of fiber type on in vitro digestion of wheat starch....

Tonyalı Karslı, Gökcem; Öztop, Halil Mecit; Şahin, Serpil; Department of Food Engineering (2021-2-10)
Essential oils are natural aromatic compounds obtained from various parts of plants such as flowers, bark, stems, and roots. They have been used in medicine, cosmetics, and food science since ancient times due to their ant...
Investigation of surface properties of quince seed extract and assessment of its performance as a novel polymeric surfactant
Kırtıl, Emrah; Öztop, Halil Mecit; Department of Food Engineering (2020-12-30)
The use of sustainable ingredients from natural sources has shown an increase in recent years. For stabilization of dispersions, proteins and polysaccharides are increasingly being used in combination for their synergistic...
Physical and chemical characterization of sesame seed protein
Köysüren, Begüm; Öztop, Halil Mecit; Bekir Gökçen , Mazı; Department of Food Engineering (2020-9)
Plant-based food proteins have become very popular and valuable due to increase trend of following a vegan diet and preferring to consume less meat in terms of sustainability reasons. The most popular plant based protein...
Improvement of pea proteins’ properties by microwave glycation
Ertuğrul, Ülkü; Öztop, Halil Mecit; Şümnü, Servet Gülüm; Department of Food Engineering (2020-9)
The tendency to include plant proteins in the diet has increased significantly as consumers' preference for animal proteins decline. Sustainability goals, low manufacturing cost, and high nutritional value are also trigg...
