Effect of hydroxypropyl methylcellulose, whey protein concentrate and soy protein isolate enrichment on characteristics of gluten‐free rice dough and bread

Research was conducted to investigate the effects of egg white protein and soy protein powder addition on physicochemical properties of banana pasta. The levels of protein fortification were 5, 10, and 15% of banana flour (w/w) for each type of protein. Pasta made from 100% of durum wheat semolina and 100% of banana were used as controls. The addition of soy or egg white protein showed significant differences on physicochemical properties compared with semolina pasta and pure banana pasta. Type of protein, level of protein, and the interaction between type of protein and the level of protein altered protein content. Soy protein gave higher protein content than egg white protein, whereas higher level of protein addition gave higher protein content of pasta. The fortified banana pasta had higher protein content than semolina pasta. There were no significant effects of soy or egg white protein addition to either insoluble or soluble dietary fiber content. It was also observed that the cooking properties of pasta (optimum cooking time, swelling index, water absorption index, and cooking loss) were affected by the level of protein addition and the type of protein. Textural analysis for tension and firmness of the pasta illustrated that protein fortification improved the textural characteristic of banana flour pasta. The addition of soy or egg white protein also improved the protein content of banana pasta making it equal to or even better than semolina pasta. Practical applicationsResearch has been carried out to improve gluten-free products, not only for people with celiac diseases, but also for those who choose a healthy lifestyle. Gluten-free ingredients are challenging to work with as they cannot create a sufficiently strong binding network between their proteins and starch in the dough, especially in some products such as pasta products. The use of an additional protein source has the ability to improve the product quality and contribute to the nutritional values which can give added value to the final gluten-free pasta product. This study reports the effects of the level of egg and soy protein fortification on the physicochemical properties of banana pasta. To the best our knowledge, there is no study which tried to develop banana pasta with protein addition alone such as soy protein isolate or egg protein powder.

Effect of egg white protein and soy protein fortification on physicochemical characteristics of banana pasta

“…Unfortunately, the gluten‐free flours (maize, rice, millet, and sorghum) cannot create a sufficiently strong binding network to produce the required quality of dough (Gao et al, ; Morreale et al, ; Wang et al, ). Hence, it is necessary to improve the pasta making process, or develop new formulation with additional ingredients, in order to make adequate sensory and cooking quality of pasta products (Djordjević et al, ; Han, Ma, Li, Zheng, & Wang, ; Padalino, Conte, & Del Nobile, ; Srikanlaya, Therdthai, Ritthiruangdej, & Zhou, ; Tan, Tan, & Easa, ).…”

Effect of cassava and banana flours blend on physico‐chemical and glycemic characteristics of gluten‐free pasta

et al. 2019

Cassava and banana flours were used in a variety of ratios (0:100, 25:75, 50:50) to produce gluten‐free (GF) pasta, the physico‐chemical and glycemic properties were investigated and compared to a control pasta made from durum wheat semolina. All GF pasta had a higher dietary fiber content, lower protein content, and a darker color compared to the control. The optimum cooking time (2.8–4.2 min) and water absorption index (23.28%–86.81%) of the GF pastas were lower than the control, while cooking loss was higher (15.18%–28.75%). The most acceptable formulation of GF Pasta among the blend ratios was achieved from 100% banana flour. GF pasta containing predominantly banana flour (75:25 banana: cassava flour and 100% banana flour) had a reduced predictive glycemic loading. The results illustrate that cassava and banana flours can be considered as suitable materials to develop gluten‐free pasta. Practical applications Research has been carried out to improve gluten‐free products in terms of physicochemical characteristics. Gluten‐free ingredients are challenging to work with as they cannot create a sufficiently strong binding network between their proteins and starch in the dough, especially in some products such as pasta products. The use of an additional banana and cassava ingredients was evaluated and the results provide valuable contribution in terms of practical uses of such ingredients in gluten‐free pasta production.

“…Currently, the production of edible SPI is mainly made of low-temperature defatted soybean meal by alkali-soluble acid precipitation (Bi, Li, Wang, & Adhikari, 2013;Xu et al, 2018). According to the remarkable physical functional properties of SPI, such as emulsifying, gelling, and hydrating (Brito-Oliveira, Bispo, Moraes, Campanella, & Pinho, 2018;Yang et al, 2018), the application of SPI is relatively mature in meat products; however, the application in cereals has great potential for improvement and research (Lee et al, 2017;Srikanlaya, Therdthai, Ritthiruangdej, & Zhou, 2018).…”

“…The purpose is to enhance the nutritional value and texture properties, furthermore ameliorating the overall quality of cereal-based products. Also, SPI has a certain effect on the rheological properties of cereal products (Srikanlaya et al, 2018;Villanueva, Perez-Quirce, Collar, & Ronda, 2018). It has been used to mimic the viscoelastic properties of gluten in gluten-free (GF) products for improving sensory properties through induction of Maillard reaction (Taghdir et al, 2017;Yang, Li, Wu, Pan, & Xia, 2017;Zhao et al, 2016).…”

2019

The viscoelastic properties of soy protein isolate (SPI) were investigated by creep–recovery under creep time (75 s, 150 s, 300 s, and 600 s), shear stress (1 Pa, 6 Pa, 10 Pa, and 20 Pa), and creep temperature (25°C, 50°C, and 80°C). Creep compliance (JC) increased proportionally with creep time from 75 to 600 s and with stress from 1 to 20 Pa, it decreased proportionally with temperature from 25 to 80°C. Results showed that the flow behavior of SPI varied along with creep time, stress, and temperature. Creep compliance data were best‐fitted to 4‐element Burgers model (R2 > .94), the instantaneous compliance (J0), retardation compliance (J1), retardation time (r1), steady‐state viscosity (η0), and recovery (%) have significant changes with creep time, stress, and temperature (p < .05). Adding maltodextrin (MD) accelerated the deformation of SPI. The flexibility and rigidity of SPI molecular chains was dependent on creep time, stress, and temperature. Practical applications In this research paper, we studied the viscoelasticity of SPI using the creep–recovery analysis. The chain flexibility, rigidity, and viscidity of SPI molecules were discussed at creep time, shear stress, and creep temperature. At the same time, the viscoelasticity of SPI adding of MD is also discussed. According to the experiment, this study provides new insights into the viscoelastic properties of SPI and builds a fundamental foundation for the comprehensive utilization of SPI in the food industry.
