Parameters analized were vitamin C content, total acid, total soluble solid, fiber content, melting speed, organoleptic of color, flavor, taste and texture. The results shows that the the effect of ratio of soursop juice with passion fruit juice had highly significant effect on vitamin C content, total acid, total soluble solid, fiber content, melting speed, organoleptic of color, flavor, taste and texture.
