Publication Open Access Antibrowning compounds for minimally processed potatoes: a review(Taylor & Francis, 2020) Bobo García, Gloria; Arroqui Vidaurreta, Cristina; Merino Antón, Gorka; Virseda Chamorro, Paloma; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura; Institute on Innovation and Sustainable Development in Food Chain - ISFOODThis review covers some recent advances in browning prevention in minimally processed potatoes (MPP). Polyphenol oxidase (EC 1.10.3.1, PPO) is one of the main enzymes involved in browning of potatoes. Antibrowning agents are used in combination with other compounds and techniques to reduce browning such as physical treatments with modified atmospheres and cold temperatures in processing and storage. Due to increasing concerns involving toxicity from various traditional food preservatives, this review focuses on studies involving substances that have different mechanisms to control browning. These substances include reducing agents, acidulants, chelating agents, enzyme inhibitors, complexing agents or others, such as Maillard reaction products and natural extracts.Publication Open Access High hydrostatic pressure processing to replace texturizing agents on a plant product intended for altered deglutition: a concept proof(Elsevier, 2023) Fernández Pan, Idoya; Merino Antón, Gorka; Virseda Chamorro, Paloma; Beriain Apesteguía, María José; Ibáñez Moya, Francisco C.; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Universidad Pública de Navarra / Nafarroako Unibertsitate PublikoaHigh 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.
