    High hydrostatic pressure processing to replace texturizing agents on a plant product intended for altered deglutition: a concept proof

    High hydrostatic pressure processing (HPP) can cause changes in food texture. These changes can be beneficial when developing food with strict texture specifications as it is the case of food targeted to people with altered deglutition (AD) issues. The aim of the present research was to evaluate the HPP potential as an alternative to the use of texturizing agents currently added to AD-targeted food products. First, formulation and experimental conditions of treatments were established, and 2 types of chickpea protein pur´ees, one containing corn starch (PS) and the other chicory inulin (PI), were developed. Second, the pur´ees were, in one case HPP-treated (300–400 MPa; 3–9 min) and in the other texturized with agar-agar and xanthan gum. Overall, HPP did not significantly affect the proximate composition of the purées and improved their microbiological quality, and, most importantly, they caused beneficial texture changes on both PS and PI purées. In addition, HPP-treatments conferred similar instrumental texture values to texturized purées. These texture values come within the given specific range data supplied by the literature for AD suitability. The present study provides the basis for applying HPP in the development of texturizer-free AD-oriented purées.

    Plant-based and hybrid patties with healthy fats and broccoli extract fortification: more balanced, environmentally friendly alternative to meat prototypes?

    Hybrid 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.
