‘明胶’ (míng jiāo) is the standard Chinese term for ‘gelatin’—a translucent, colorless, flavorless food ingredient derived from collagen, typically extracted from animal skin and bones (especially cattle and pigs). The character 明 (míng) here does not mean ‘bright’ or ‘clear’ in the usual sense; rather, it’s a phonetic component borrowed for its sound, while 胶 (jiāo) means ‘glue’ or ‘gum’, reflecting gelatin’s adhesive and gelling properties. Together, the word emphasizes its function as a natural setting agent.

This substance is widely used in food production (e.g., jellies, marshmallows, yogurt stabilizers), pharmaceuticals (capsule shells), and photography (as a binder in film emulsions). Although plant-based alternatives like agar exist, ‘明胶’ specifically refers to animal-derived gelatin and is never used for vegetarian substitutes. It’s a technical yet common term in ingredient labels, cooking instructions, and food science contexts in Chinese-speaking regions.
