La presente tesi inizia con un’analisi dell’aspetto nutrizionale degli alimenti. In particolare, è stato discusso il concetto di dieta equilibrata, con riferimento ai principi della “dieta mediterranea”. Proprio da questo modello alimentare trae ispirazione la “ottimazione”, una tecnica sviluppata e utilizzata per programmare pasti conformi a specifici standard nutrizionali (15/30/55 tra proteine, lipidi e carboidrati sull’apporto energetico totale, proporzioni tipicamente mediterranee). Tali preparazioni alimentari sono state testate anche attraverso metodi di analisi sensoriale. Il passaggio successivo è stato l’estensione del concetto di “ottimizzazione nutrizionale” a quello di “ottimizzazione ambientale”, dovuto all’ipotizzato minor impatto ambientale della dieta mediterranea. Il LCA (Life Cycle Assessment) è la tecnica che è stata utilizzata per valutare l’impatto ambientale di alcuni prodotti alimentari, quali verdure surgelate, un salume e un formaggio. Un ulteriore passaggio è stata la creazione di uno strumento di comunicazione, una nuova etichetta ambientale, realizzata per essere utilizzata dalle aziende per comunicare le loro performance ambientali e quindi il loro impegno al miglioramento continuo, e dai consumatori per ottenere maggiori informazioni sull’impatto ambientale dei prodotti acquistati quotidianamente, al fine di accrescere il proprio senso critico ed effettuare acquisti consapevoli.

Abstract
The thesis begins with an analysis of the nutritional aspects of foods. In particular, the concept of balanced diet has been discussed, by referring to the principles of "mediterranean diet". Just from this food model, the “optimation” draws inspiration, a technique developed and used to plan meals consistent with specific nutritional standards (15/30/55 between protein, fat and carbohydrate on the total energy intake, typically Mediterranean). These food preparations have been tested through sensory analysis methods. The next step is the extension of "nutritional optimization" concept to the "environmental optimization” one, owing to the presumed lower environmental impact of the Mediterranean diet. LCA (Life Cycle Assessment) is the technique used to assess the environmental impact of various food products, such as frozen vegetables, cured meats, dairy products. A further step is the creation of a communication tool, a new environmental label, designed to be used by companies to communicate their environmental performance and therefore their commitment to continuous improvement, and by consumers to obtain more information on the environmental impact of the foods daily consumed, in order to increase their critical sense and make purchases in a conscious way.File | Dimensione | Formato | |
