Descripción
Partial enzymatic hydrolysis is frequently used as strategy to improve the functional and nutritional properties of vegetable proteins. The aim of this work was to evaluate the hydrolysis of quinoa proteins, as well as the functional and antioxidant properties of their acid-induced gels. In order to fulfil this purpose, quinoa protein hydrolysates were obtained using a fungal serin protease. The hydrolysis degree, surface hydrophobicity, sulphydryl group content and the electrophoretic profile of hydrolysates were assayed. Hydrolyzed quinoa protein acid-induced gels were carried out and gels obtained were tested for their textural characteristics, water holding capacity, appearance (color and microstructural properties) as well as for their in vitro antioxidant activity. The changes occurring during the enzymatic hydrolysis affected the gel-forming ability of quinoa proteins and therefore the characteristics of gels. After 3 h of proteolysis, protein hydrolysates with 17 ± 2% hydrolysis degree and low surface hydrophobicity were obtained. Gels obtained of these hydrolysates presented less interconnected protein network and thus, lower textural parameters and lower water holding capacity than control gels. In conclusion, even though the hydrolysis treatment negatively affects the gelling properties of the quinoa proteins, limited hydrolysis enables us to obtain gels with antioxidant capacities which present differential characteristics.
