Etude des procédés de fabrication du chocolat, propriétés physicochimiques et microbiologiques, et valeur nutritionnelle

Abstract

Chocolate is one of the world's most popular foods and confectionery products. It is derived from cocoa beans, which are processed into a paste used in many culinary preparations, and offers a wide range of flavours, from sweet to bitter, depending on the cocoa content. Chocolate is a high-calorie food, rich in lipids and sugars, which is why it is advisable to consume it in moderation. However, it has been associated with health benefits. Dark chocolate, in particular, is rich in antioxidants and flavonoids, which can help protect the body against damage caused by free radicals. The aim of this work is to contribute to the study of different chocolate manufacturing processes, as well as its nutritional and hygienic quality. The various stages in the chocolate manufacturing process were described, from harvesting to the finished product. The various biochemical, microbiological and physicochemical characteristics and their interpretations were reported. This study confirms the nutritional value of chocolate consumption, highlighting the various health benefits of this product, but not forgetting its pathological impact in certain cases.
