Legume flours are great sources of protein, dietary fiber, starch, minerals, and vitamins. In recent years, the utilization of different legume flours in food systems has gained attention due to their sustainable and functional properties. This study aimed to characterize and examine the water interactions of different legume flours: navy bean, chickpea, pea, and lentil. For this purpose, in addition to the standard techniques (proximal analysis, Fourier transform infrared, protein solubility, and water solubility/absorption index), time-domain nuclear magnetic resonance (TD-NMR) relaxometry was also performed to explain the molecular interactions in the flours. Based on the results, carbohydrate and protein content of legume flours varied from 67.44 to 72.23 (g/100 g dw) and 23.19 to 27.03 (g/100 g dw) with low fat (0.86–5.44 [g/100 g dw]) and moisture content (6.01–8.14 [g/100 g dw]). Despite the slight differences in their compositions being small, moisture, protein, and carbohydrate contents influenced flour–water interactions. Thus, flour–water mixtures were assessed, and findings showed that water solubility index (WSI) followed the order: chickpea > lentil > navy bean > pea, whereas water absorption index (WAI) followed the order: pea > navy bean > lentil > chickpea. T2 relaxation times measured by NMR and protein solubility results were also in accordance with these results. The results of this study demonstrated that legume flours that were investigated offered potential for commercial applications. Because various food applications require different flour–water interactions, a suitable flour can be selected by considering these results.

Investigation of in-vitro digestive behavior of beef and poultry which are tenderized by enzymatic and acidic marination
Baştürk, Bilge; Öztop, Halil Mecit; Özvural, Emin Burçin; Department of Food Engineering (2021-9-09)
Meat contains valuable nutrients, exceptionally high-quality proteins that include all essential amino acids and vitamins and minerals for the human diet. Meat is mostly tenderized to make it more tasteful and palatable. The effects of tenderization on the physical, chemical, and microbiological changes in meat have been investigated in many studies. In this study, acetic acid, citric acid, lactic acid solutions, and a commercial meat tenderization solution were used to tenderize the red and white meat (bee...
Formulation and characterization of chia seed oil nanoemulsions
Kaya, Eda Ceren; Alpas, Hami; Department of Food Engineering (2019)
Chia seed is a good source of not only protein, dietary fiber and antioxidants but also polyunsaturated fatty acids, which are in higher amounts compared to other seedbased food sources. Nanoemulsions are colloidal dispersions that contain small particles, typically around 20-200 nm in diameter, that may not be distinctively visible since they do not scatter light strongly. Moreover, they have strong stability and can protect the embedded oil from oxidation. Thus, utilization of nanoemulsions from chia seed...
Effects of legume flours on batter rheology and cake physical quality
Aydoğdu, Ayça; ÖZKAHRAMAN, Canan; Şümnü, Servet Gülüm; Şahin, Serpil (2016-08-25)
Legumes are good sources of proteins, carbohydrates, dietary fibers and minerals. Therefore, legume flours can be a good choice to obtain functional foods. The aim of this study is to examine the effect of legume flours (lentil, chickpea and pea) on rheological properties of cake batter and quality of legume cakes. Wheat flour was replaced partially (20 and 30%) by lentil, chickpea and pea flour to develop legume cake formulations. As quality parameters, weight loss, specific volume, hardness and color were...
EFFECTS OF HYDROCOLLOIDS AND CAROB BEAN FLOUR ON RHEOLOGICAL PROPERTIES OF BATTER AND CAKE QUALITY
BERK, EDA; Şümnü, Servet Gülüm; Şahin, Serpil (2017-01-01)
Carob bean flour which contains significant amount of dietary fiber, amino acid and minerals can be an alternative flour to enrich nutritional value of gluten free cakes. The objective of this study was to determine the effects of partial replacement of rice flour by carob bean flour at different concentrations (10%, 20%, 30%) and addition of different types of gums (xanthan gum, and guar gum), on specific gravity and rheological properties of gluten free cake batters. In addition, quality of cakes (weight ...
Utilization of lentil flour as a biopolymer source for the development of edible films

Lentils are one of the cheapest and most nutritional protein sources for vegetarians. Our objective in this study was to evaluate the feasibility of using lentil flour as a raw material for the development of edible films and to investigate the effects of the glycerol concentration (C-g=1%, 1.5%, and 2%) and process temperature (T-p; 70 and 90 degrees C) on the physical properties of these films. The films were characterized via their density; water solubility; thermal, morphological, and chemical character...
