However, in Portugal frequency of consumption is smaller when compared to other European countries, although dark chocolate is the most preferred type of chocolate.

Consequently, this thesis reflects the development of new products as chocolate tablets and chocolate dragées, namely chocolate tablets with inclusions of lime nuggets and crunchy cereal, and milk chocolate covered cereal. Development of these projects consisted of different stages until the final prototype was achieved. Among them, there was research regarding ideal raw material to be used and the in laboratory development itself. The final prototype was validated and approved under sensory analysis and tests, and whenever necessary, industrial-scale tests were also performed. As a final step, mandatory elements relating to labeling necessary for the product's packaging were developed. In conclusion, general and specific objectives set for this work were achieved, as projects that were elicited have been successfully implemented, with respective evaluation and approval.
