The Chinese word 脱脂 (tuōzhī) is a compound formed by combining the verb 脱 (tuō), meaning "to shed," "to remove," or "to free from," with the noun 脂 (zhī), which means "fat" or "grease." Together, they create a verb-object structure that literally means "to remove the fat," describing a process where fat content is extracted or separated from a substance. This term is most commonly applied to food products (like 脱脂牛奶, skimmed milk) or cleaning agents (脱脂剂, degreaser) to indicate they are non-fat or have had their fatty components eliminated.
