Physicochemical And Functional Properties

<p>This study sought to determine the physicochemical and functional properties of yam bean (<em>Pachyrhizus erosus</em>) seed proteins. <em>Pachyrhizus erosus</em> seeds from two accessions (UYB 06 and UYB 07) were milled into flours and then defatted. A portion of the defatted flour was used for production of protein isolates and protein fractions. The physicochemical and functional properties, <em>in vitro</em> digestibility and electrophoretic pattern of the flour and protein isolate were determined. The results showed that albumins (53.3%) were the dominant protein fraction followed by globulins (18.7%), glutelins (8.8%) and prolamins (2.7%). Regarding functional properties, the <em>Pachyrhizus erosus</em> seed protein isolates exhibited 8% of least gelation concentration, water absorption capacity of 3.0 g g<sup>-1</sup>, oil absorption capacity of 0.8 g g<sup>-1</sup>, protein solubility of 81.0%, foaming capacity of 37.1%, foam stability of 73.8%, emulsion activity of 13.8% and emulsion stability of 9.2%. <em>In vitro</em> protein digestibility of the raw and cooked beans was 87.6% and 84.3%, respectively. The electrophoretic pattern of<em> Pachyrhizus erosus</em> protein showed major bands corresponding to molecular weight 13.3, 15, 29.8, 54.4 and above 84.7 kDa. The results, suggest that <em>Pachyrhizus erosus </em>seed protein has potential for use in both food and non-food applications such as films and coating.</p>

This study aimed to determine the proximate compositions and functional properties of sweet potato flour from different varieties cultivated in Sabah, Malaysia, namely Jepun, Kairot and Kaladi. The results showed that the moisture content of all flour samples was below 14%. The fat and protein content of Jepun sweet potato variety were significantly different (p<0.05) as compared with Kairot and Kaladi sweet potato varieties. The ash and dietary fibre content of Kairot sweet potato flour were higher (p<0.05) compared to Jepun and Kaladi flours. In addition, Kaladi sweet potato had the highest carbohydrate content (82%). There were significant differences (p<0.05) in the values of L*, a* and b* for all sweet potato flours. The Jepun sweet potato flour had the highest foaming capacity, water absorption capacity, oil absorption capacity, swelling power and viscosity. Rapid Visco analyser revealed that significant differences were observed for pasting parameters such as peak viscosity, trough viscosity, breakdown viscosity, final viscosity and setback viscosity. The gelatinisation properties showed that Kairot sweet potato flour had the highest onset temperature, conclusion temperature and enthalpy while Kaladi sweet potato flour had the highest peak temperature.

AbstractCamelina and flixweed (sophia) seed protein isolates were prepared using both the conventional extraction and ultrasonic-assisted extraction methods at 40 kHz for 20 min, and their functional properties investigated. SDS-PAGE showed that both ultrasound-assisted and conventional extractions resulted in a similar protein profile of the extract. The application of ultrasound significantly improved protein extraction/content and functional properties (water holding capacity, oil absorption capacity, emulsifying foaming properties, and protein solubility) of camelina protein isolate and sophia protein isolate. The water-holding and oil absorption capacities of sophia protein isolate were markedly higher than those of camelina protein isolate. These results suggest that camelina protein isolate and sophia protein isolate may serve as natural functional ingredients in the food industry. Graphical Abstract

Physicochemical And Functional Properties

Considering the nutritional and functional characteristics of chickpea, flours of two varieties of chickpea (“Blanco Noroeste” and “Costa 2004”) were prepared to know the effect of cooking. Thus the objective of this study was to compare their physicochemical and functional properties in both, raw and cooked flours. Physical properties of the grain, for the two varieties were similar, whereas the physicochemical and functional properties of the flours exhibited differences as a function of the variety and the processing. The chickpea cooked flours showed lower lightness and higher redness and yellowness with respect to raw flours. The proximal composition of cooked flours presented significant differences in fat (5.98% - 6.09%) and moisture contents (0.48% - 0.54%) with respect to raw flours. The particle size distribution determined for the raw and cooked flours samples, indicated a unimodal behavior with a wide distribution. The water absorption capacity and oil capacity showed significant difference among flour varieties. For pasting properties, a higher viscosity was measured for Costa 2004 (380 cP) and Blanco Noroeste (272 cP) raw flours, raw flour exhibited better pasting properties than cooked flours.
