摘要： Methods of making and resultant acidulent/carbohydrate agglomerates. The acidulent may be citric acid having particle sizes ranging from about 1 micron to 20 microns agglomerated with a soluble carbohydrate co-agglomerate to formulate the various acidulent/carbohydrate agglomerates. In certain embodiments, the carbohydrate co-agglomerate may be maltodextrin to formulate citric acid/maltodextrin agglomerates. These citric acid/maltodextrin agglomerates are shelf stable when dry, have improved flowability, compressibility, mixability; dissolve easily and quickly in water; and provide an easy ready-to-use formulation that is suitable for use in compounding various food and pharmaceutical products.
