摘要:This paper presents determination of x-carrageenan in foods by sandwich enzymeimmunoassay. x-Carrageenan was determined after removal of fat and dyes from various foods with dioxane. Amount of x-carrageenan in jelly was between 0.24 and 0.76% and the recovery was between 89 and 101% when 1.0% of carrageenan was added to jelly. For pudding, ice cream, whip cream and jam, the recovery was between 89 and 99% when 0.2-1.0% was added to each food.
