The reasons for adding taurine to candies are primarily based on taurine's various functional properties and its ability to enhance the quality of candies.

Taurine can enhance the umami and salty flavors in foods, making candies with added taurine taste more delicious and appealing. As an important nutrient, taurine is beneficial to human health, so adding it to candies can provide nutritional value while enjoying the treat. Taurine also has pH-regulating properties, which help maintain the stability and taste of candies. Additionally, its antioxidant properties can extend the shelf life of foods, which is significant for the preservation and quality assurance of candies.

In candies, taurine can act as a taste modifier, improving the texture and mouthfeel of candies, making them finer and softer, thereby enhancing the consumer's eating experience. Due to its moisture-retaining properties, taurine helps keep candies moist and soft, preventing them from becoming dry and hard during storage and transportation. In some functional candies, taurine is used as an energy supplement. As an important amino acid, it plays a crucial role in replenishing energy. Therefore, adding it to candies can provide consumers with additional energy support.

With the increasing consumer demand for health and quality, the market demand for functional candies is also growing. Taurine, as a food additive with various functional properties, meets consumers' needs for health, taste, and energy supplementation, leading to its widespread application in candies.

The reasons for adding taurine to candies include its unique functional properties, its enhancement of candy quality, and the driving force of market demand and consumer preferences. These factors collectively make the application of taurine in candies a trend and a choice.
