Description du projet
Imprimer des aliments personnalisés pour les personnes âgées
Un vieillissement en bonne santé nécessite de bonnes habitudes alimentaires, mais les adultes plus âgés sont vulnérables à la malnutrition. Ce fait s’explique essentiellement par une perte d’appétit, des problèmes dentaires, des troubles psychosociaux et des maladies chroniques. Détecter rapidement la malnutrition permet d’intervenir à temps. Le projet 3D-NANOFOOD, financé par l’UE, apportera sa contribution en fabriquant des aliments personnalisés ayant une valeur nutritive supérieure. Pour ce faire, il exploitera l’impression 3D pour la production rapide d’aliments et la flexibilité. Le projet utilisera des systèmes d’administration nanostructurés, afin de protéger et d’améliorer la performance des composés fonctionnels. Il évaluera la qualité et la fonctionnalité des nouveaux aliments, et mettra au point un protocole industriel pour la fabrication d’aliments imprimés.
Objectif
Ageing accelerates the prevalence of malnutrition due to physiological changes, such as masticatory and swallowing dysfunctions, body composition changes and special nutrition needs. In addition, degradation of sensory functions in seniors results in an appetite decrease. Therefore, personalised foods that enable optimal nutritional maintenance and food pleasantness are required, being a cornerstone for healthy ageing. The main goal of this research project is to provide innovative and feasible strategies to manufacture personalised foods for older adults with superior nutrition and sensory properties. This action proposes the combination of promising techniques including nanoencapsulation, food enrichment and 3D printing to manufacture personalised foods. 3D printing is a versatile and emerging technology that will enable fast food manufacturing and flexibility to formulate products with target texture and special nutrition needs. Food enrichment with functional compounds (e.g. flavourings and bioactive compounds) can improve the quality and functionality of printed foods. For instance, flavourings can reinforce the taste and smell of printed foods, making them more palatable; while fortification with bioactive compounds can promote health. However, the process of food fortification entails technological challenges, affecting the food attributes. This will be addressed using nanostructured delivery systems for protecting and/or enhancing the performance of functional compounds. The work plan of this project proposes: 1) the fabrication of nanoparticles and nanostructured layers using electrospraying and ultrasonic spray for delivering bioactive compounds and flavours; 2) the design of texture-modified foods using 3D printing containing nanoparticles or nanostructured layers loaded with functional compounds; 3) the evaluation of the quality and functionality of the new foods developed, and 4) the development of an industrial protocol for printed foods manufacturing.
