PURPOSE: Powder drink which easily melts in water is provided to easily mix the powder drink with a solvent without applying external physical impact.CONSTITUTION: Powder drink is formed of a component (200) which is familiar with a solvent, another component (201) which is not familiar with the solvent, and a colloid formation prevention component (300). The component which is familiar with the solvent is mixed with solvent molecules (100) by bonding or by attraction, and the component which is not familiar with the solvent is mixed with the solvent by the attraction caused from the colloid formation prevention component and the solvent. The component which is familiar with the solvent is arranged toward the solvent molecules, and the component which is not familiar with the solvent is arranged in the opposite direction.COPYRIGHT KIPO 2013[Reference numerals] (100) Solvent molecule (200) Component which is familiar with the solvent (201) Component which is not familiar with the solvent (300) Colloid formation prevention component본 발명은 용매와 용질의 극성의 차이등의 원인으로 인해 생기는 콜로이드의 생성을 억제하는 성분을 첨가한 가루음료 로써, 용매에 덩어리 혹은 콜로이드의 형성을 방해하여, 용매에 쉽게 혼합시킬 수 있는 것을 특징으로 하는 물에 쉽게 녹는 가루음료에 관한 것이다.
