Polyols and chocolate technology: recent developments and advances.

This article focuses on the use of polyols as sugar replacers in chocolate production to develop low-calorie and sucrose-free chocolates that meet consumer demands and public health goals without compromising quality. Polyols, sugar alcohols derived from natural carbohydrates, offer bulking properties similar to sucrose and can be used partially or fully to reduce calorie content, with maltitol and xylitol highlighted for their favorable sweetness and functional characteristics. The study discusses the impact of polyols on chocolate's rheological properties, sensory attributes, shelf life, and fat bloom stability, emphasizing the need to optimize processing conditions such as refining, conching, and tempering to maintain product quality. It also notes the importance of investigating interactions between polyols and bioactive compounds, as well as addressing challenges like moisture absorption and cooling effects inherent to polyols. Overall, the article underscores polyols' potential to produce healthier chocolate alternatives aligned with evolving consumer preferences and regulatory environments.
