This study optimized the rheological parameters of doughs with partial substitution of wheat flour for blends of whole grain flours from germinated Andean pseudocereals such as quinoa (GQF), kiwicha (GKF), and cañihua (GCF) for bread production. The optimization was conducted through a Simplex-Centroid Mixture Design (SCMD) and Desirability Function (DF). Experiments were formulated using 80 to 90% wheat flour and 5 to 15% germinated pseudocereal blends. The rheological evaluation included farinograph, extensograph, and amylography analyses. Results showed that whole flour from germinated pseudocereals increases the water absorption, consistency, and extensibility of the doughs; and decreases its development time, stability, resistance to extensibility, temperature, and peak viscosity. The GQF-GKF blend developed more extensible and stable doughs, while GCF increased its consistency and was recommended for bread production. The data allowed us to obtain response surface models and the optimal substitution percentages to produce bread using GQF-GKF, GQF-GCF, and GKF-GCF blends. [ABSTRACT FROM AUTHOR]

Currently, the food industry prioritizes the safety and quality of products, facing the challenge of maintaining sensory and nutritional integrity. To address this challenge, emerging non-thermal technologies are being explored that offer significant advantages in improving food quality over conventional technologies. This review aims to provide a comprehensive understanding of how these innovative technologies can transform the traditional food processing landscape as we know it. Non-thermal technologies have the potential to reduce energy consumption for food production, processing and packaging, compared to conventional thermal treatments. Furthermore, these technologies are particularly suitable for efficiently preserving bioactive compounds present in foods. This review describes the fundamental principles, applications, advantages and limitations of emerging technologies in food processing. These technologies include pulsed electric field, ultrasound, cold plasma, high pressure, irradiation, light-emitting diodes, pulsed light and oscillating magnetic fields. Despite the large number of studies on the subject, more research is required to optimize and improve the efficiency of the application of these technologies, alone or in combination, in food processing. The bioaccessibility and bioactivity of the compounds, nutritional value, shelf life and sensory aspects may be variables of interest. [ABSTRACT FROM AUTHOR]
