Through the last years consumers have shown a growing interest in minimally processed foods with clean labels that not only satisfy basic nutrition but also provides health-benefits. This has motivated scientists and technologists to find optimal combination of ingredients and novel technologies to produce functional products with attractive sensory properties. Red prickly pears (RPP) and soymilk (SM) have been recognized as rich sources of antioxidant compounds with health properties. Moderate intensity pulsed electric fields (MIPEF) application in plant-based foods increases phytochemicals content through stress induction or improved extraction yields. Hence, the aim of this work was to enhance the bioactive compounds content of RPP and SM by MIPEF and use them for the development of a plant-based beverage with potential health-benefits. Results indicated that MIPEF-processing increased the bioactive compounds content of RPP and SM, resulting in a plant-based beverage with higher concentration of total phenolic compounds (16%), betalains (7.2%) and isoflavones (7.4%) than the control-beverage. Furthermore, MIPEF application to the ingredients did not affect physicochemical attributes of the beverage, obtaining an appealing product with potential health-attributes. Pulsed electric fields processing at moderate intensities (<5 kV/cm) might be a potential way to enhance the phytochemicals concentration of plant-based ingredients used for the development of beverages with clean-labels, minimally processed and potential health benefits. This kind of products could satisfy current consumers' demand in special situations of health. However, further research must continue to better understand the mechanisms occurred during processing and to find the best processing parameters for different raw materials. • MIPEF process of red prickly pears or soymilk enhance bioactive compounds content. • MIPEF-ingredients can be used in plant-based beverages formulation with clean labels. • Plant-based bevearges represent a potential way to include health compounds in diets.
