INTRODUCTION Les fruits jouent un rôle essentiel dans l'alimentation humaine, étant une riche source de vitamines et de minéraux. Cependant, leur nature périssable a conduit à leur transformation en produits conservés comme la confiture, afin d'allonger leur durée de conservation et de minimiser les altérations oxydatives, enzymatiques et microbiennes. Depuis l'Antiquité, l'homme cherche à conserver les aliments pour les protéger des conditions climatiques difficiles, et diverses méthodes de conservation ont vu le jour, notamment la cuisson, le séchage et l'ajout de sucre. La confiture est l'une des plus importantes de ces méthodes : préparée à partir de fruits et de sucre, elle permet de conserver les fruits tout en préservant et en rehaussant leur saveur, et en réduisant le gaspillage des fruits mûrs ou excédentaires. Ce mémoire est structuré en quatre parties : généralités sur la confiture, matériels et méthodes, résultats et discussion, puis conclusion générale..
