Publication Open Access Plant-based and hybrid patties with healthy fats and broccoli extract fortification: more balanced, environmentally friendly alternative to meat prototypes?(MDPI, 2025-02-01) González Peñalver, José Miguel; Martínez Aldaya, Maite; Villaño Valencia, Débora; Virseda Chamorro, Paloma; Beriain Apesteguía, María José; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura; Ciencias; Zientziak; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Gobierno de Navarra / Nafarroako GobernuaHybrid and plant-based products are an emerging trend in food science. This study aimed to develop three patty prototypes (meat, hybrid, and plant-based) enhanced with vegetable fat replacement and broccoli extract using a soy allergen-free protein matrix treated with high hydrostatic pressure (HHP) and sous vide cooking to create sustainable and nutritious burger alternatives. The samples were evaluated for microbiological safety, proximal composition, physicochemical properties, sensory characteristics, and carbon footprint. The key findings revealed that the plant-based patties had the smallest carbon footprint (0.12 kg CO2e), followed by the hybrid patties (0.87 kg CO2e) and the meat patties (1.62 kg CO2e). The hybrid patties showed increased hardness, cohesiveness, gumminess, and chewiness compared to the meat patties after sous vide treatment. This improvement likely results from synergies between the meat and plant proteins. Regarding the treatments, in all the samples, the highest hardness was observed after the combined HHP and sous vide treatment, an interesting consideration for future prototypes. Sensory analysis indicated that the plant-based and hybrid samples maintained appealing visual and odour characteristics through the treatments, while the meat patties lost the evaluator¿s acceptance. Although further improvements in sensory attributes are needed, hybrid patties offer a promising balance of improved texture and intermediate carbon footprint, making them a viable alternative as sustainable, nutritious patties.Publication Open Access Revalorisation of broccoli crop surpluses and field residues: novel ingredients for food industry uses(Springer, 2023) Villaño Valencia, Débora; Fernández Pan, Idoya; Arozarena Martinicorena, Íñigo; Ibáñez Moya, Francisco C.; Virseda Chamorro, Paloma; Beriain Apesteguía, María José; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Universidad Pública de Navarra / Nafarroako Unibertsitate PublikoaResearch on the management of broccoli crop residues and surpluses is critical for improving agricultural practices, optimizing food industrial manufacture, and contributing to better human nutrition. The objective of this study was to obtain novel ingredients based on these residues and surpluses for a wide range of applications in the food industry. The efect of air-drying (60 °C or 80 °C) applied to feld residues (broccoli stalks), mimicking industrial conditions, was compared with dehydration by freeze-drying applied to these same feld residues and to crop surpluses (broccoli whole plant). Thus, diferent broccoli fours were obtained and characterised for technological and biological properties including colour, antioxidant activity, nutrients, total polyphenol content, and content of glucosinolates. Flours from feld residues showed high levels of dietary fbre (≈22% dry weight). Broccoli crop surpluses fours had relevant contents of glucosinolates (≈13 mg/g dry weight). Therefore, within the framework of the circular economy, these fours are proposed to revalorise the two main broccoli crop discarded fractions. Such fours could be used in a realistic and simple way by the agri-food industries interested in the development of healthy and conscience foodstufs, in a cost-efcient manner.
