              <p>OPTIFEL was dedicated to the definition, elaboration and validation of attractive foods for seniors, based on fruit and vegetables. To conciliate the pleasure of eating with nutritional aims to palliate malnutrition of seniors, OPTIFEL used an integrative approach. It took into account seniors’s nutritional needs but also preferences for taste, types of fruit and vegetables or modes of preparation. Their capacities for taste discrimination, eating capability, especially as related to food texture, size of portions and ease of opening of packaging were also factored in the products. The sustainability of the modes of distribution was evaluated. Selected products concepts were elaborated using traditional and innovative food processing technologies. Savoury products were enriched in proteins (enriched soups, culinary aids and vegetable purees), while sweet products were enriched in vitamins, minerals and fibers (smoothies, apple desserts, healthy confectionary and apple wedges with watermelon texture). These products were characterized for their safety during storage and reheating as well as preservation of the nutritional value of the enrichments. Hedonic rating by autonomous seniors was used to select the best recipes and products for trials in elderly people living at home and eating in community services or at home receiving meals-on-wheels in nursing homes.</p>

              <p>Le projet OPTIFEL (projet européen FP7) avait pour ambition de concevoir des produits innovants à base de fruits et légumes pour l’alimentation des personnes âgées en perte d’autonomie. Les étapes du projet: 1) identifier les besoins et les souhaits des seniors ; ces attentes ont été résumées sous forme de lignes directrices et d’un calculateur nutritionnel ; 2) imaginer des produits répondant à ces attentes, optimisés en termes de composition nutritionnelle mais surtout de goût et de texture pour qu’ils soient consommés avec plaisir, imaginer des emballages adaptés ; 3) les élaborer en utilisant les technologies adaptées et innovantes, et vérifier qu’ils remplissent les caractéristiques hédoniques, nutritionnelles et de sécurité attendues ; 4) les faire valider par des personnes âgées autonomes, fragiles ou dépendantes, en prenant en compte satisfaction exprimée et consommation effective. Différents types de produits ont été élaborés : smoothies, compotes, bouchées (sucrées ou salées), purées, aides culinaires et soupes enrichies en protéines végétales ou vitamines et minéraux, panier personnalisé pour portage. L’incorporation de « produits OPTIFEL » dans un repas permet une augmentation significative de la consommation calorique et protéique par rapport aux produits génériques.</p>
