Chocolate is a pleasurable product, which is largely consumed over the world and has been studied for many years. We know that ingredients, process, and particle size distribution largely impact the chocolate sensory properties.Some studies also looked at the influence of the manufacturing process on dark chocolate sensory properties.The unique chocolate matrix is a mixture of sugar and cocoa particles dispersed in a cocoa butter phase, yet its specific packing structure and particle interactions make chocolate an even more intriguing and complex substance. Chocolate texture is a combination of triglyceride packing structures (polymorphs), microstructural properties, dispersed particulates, particle size distribution,
and solid fat content (SFC), the ratio of solid to liquid fat in a product.Chocolate has a shelf life of approximately 12 to 24 month.With improper storage, these changes can be magnified, causing an increase in particle size, which is extremely
important to mouthfeel. Effect of storage conditions leading to bloom formation in dark chocolate was evaluated by sensory evaluation.
