| Abstract | ||
| Quinoa is a pseudocereal plant that has been cultivated in Iran recently. The purpose of this research was to evaluate its properties for use in food. Quinoa protein isolates (QPIs) were isolated from Iranian quinoa seed cultivar (QS) varieties (Black-QS, Q12-QS, and Titicaca-QS). The Black-QPI and Titicaca (T)-QPI had a higher protein content (87.30±1.96, 87.80±1.61% w/w), respectively. The results showed foaming capacity (40.54%), stability (65.26% in 60 min), and oil absorption (3.02 ml/g) were significantly (p ≤ 0.05) was higher in Black-QPI. Textural parameters revealed that viscosity and shear stress were higher in Q12-QS than others. The amino acid profile showed that T-QS had a well-balanced profile with the highest content of tryptophan (8.23 %). Consequently, the suitable nutritional and functional properties of Titicaca protein make it an appropriate candidate for use as a safe food additive. | ||
