Publication Open Access Extra-virgin olive oil enriched with lycopene: from industrial tomato by-products to consumer(Wiley, 2024) Fernández Pan, Idoya; Horvitz Szoichet, Sandra Susana; Ibáñez Moya, Francisco C.; Arroqui Vidaurreta, Cristina; Beriain Apesteguía, María José; Virseda Chamorro, Paloma; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Universidad Pública de Navarra / Nafarroako Unibertsitate PublikoaLycopene is usually extracted from the by-product of the tomato industry using organic solvents (OS) in combination with a physical technique. An emerging physical technique is high-pressure processing (HPP). This study aims to find a method by applying a green solvent (edible vegetable oils) in an HPP-assisted solid-liquid extraction. Three dosages of tomato by-product (10%, 20%, and 40%, w/v) were tested using OS, sunflower oil (RSO), and extra-virgin olive oil (EVOO). Lycopene recovery increased with the ratio of by-product to oil, particularly when using EVOO. In another stage of the study, consumers evaluated EVOO that contained two doses of tomato by-product (10% and 20%, w/v). Consumers preferred the EVOO from 10% tomato by-product ratio over that with 20%. Additionally, 83.8% of consumers stated that enriched oil could be deemed beneficial for health. The proposed method considers the fundamental principles of the circular economy and practical industrial scenario to recover lycopene from tomato by-product.Publication Open Access Impact of a dual treatment on resistant starch level and techno-functional properties of pea and faba bean flours(Wiley, 2024-10-25) Arroqui Vidaurreta, Cristina; Noriega Domínguez, María José; Ibáñez Moya, Francisco C.; Milagro, Fermín I.; Beriain Apesteguía, María José; Virseda Chamorro, Paloma; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa; Gobierno de Navarra / Nafarroako GobernuaStarch-rich pulses' flours, which are rich in fiber and resistant starch (RS), can be an interesting gluten-free ingredient for the development of novel healthy foods. The study aims to increase the RS content of protein-reduced fraction of legume flours (pea [P] and faba bean [FB]) by the application of thermal (autoclaving-cooling) and dual (thermal plus high-hydrostatic pressure) treatments. Both treatments enhance the RS contents, reaching 6.8% in P flour after dual treatment. The techno-functional properties are dependent both on the type of flour and the treatment applied. A loss of water solubility (WS) and an increase in water binding capacity are observed. The WS index and emulsion activity remained unchanged or slightly changed, but emulsion stability decreased significantly. The viscosity of the samples is modified according mainly to the flour type. P flour is more affected by the dual treatment than FB flour, which is evidenced by the greater changes shown in RS, WS, and pasting properties.
