麥芽糊精是一種從澱粉（多為玉米、小麥、馬鈴薯或米）水解而來的中間物，能簡單理解為：澱粉 > 麥芽糊精 > 糖，外觀通常為白色粉末，是運動飲料中的主要能量來源。

Maltodextrin is useful for endurance athletes like cyclists, as it is a fast-digesting carbohydrate with a high glycemic index, providing quick energy during prolonged exercise (like long rides) or aiding post-workout glycogen recovery.

Its neutral taste, easy solubility in water, and gentle effect on the stomach make it a common ingredient in sports drinks and energy gels.

麥芽糊精可依 DE 值（Dextrose Equivalent，葡萄糖當量） 0–100 區分。

DE 值越高：

• 越甜
• 吸收越快
• 滲透壓越高
• 越接近葡萄糖

Maltodextrin used in energy gels typically has a DE between 10 and 20.
