This study aimed to determine the impact of incorporating ginger powder into chocolate on its sensory quality, including taste, aroma, texture, and overall acceptability. Ginger powder was selected as an additive due to its potential health benefits and unique flavor profile, which could offer an exciting twist to traditional chocolate.

In this experiment, different concentrations of ginger powder were added to a standard chocolate recipe. Consumer testing was done evaluating the sensory attributes of the ginger-infused chocolates. The panelists rated the chocolates on various sensory characteristics using a structured scoring system.

The results indicated that the addition of ginger powder significantly influenced the sensory attributes of the chocolate. The taste profile of the ginger-infused chocolates exhibited distinct spicy, warm, and earthy notes attributed to the ginger. The aroma of the chocolates also exhibited a pleasant fusion of chocolate and ginger scents. Moreover, the texture of the ginger chocolates showed slight variations compared to the standard chocolate, with a subtle graininess due to the presence of ginger particles.

Further analysis showed that the sensory acceptability of the ginger-infused chocolates varied among the consumers. Some individuals enjoyed the unique flavor experience, describing it as a harmonious combination of chocolate and ginger, while others found the ginger flavor overpowering or incompatible with chocolate.
