2 Fuctioal Acids Fuctioal modificatio advaced tools Jugbuzlauer s experiece has led to a outstadig rage of products to satisfy customer eeds for sophisticated fuctioal igrediets ad additives. Citric acid is a aturally occurig fruit acid ad the most importat orgaic acid for pharmaceutical, food ad techical applicatios. It provides excellet properties as a acidulat, ph cotrol aget ad supports crystallizatio processes. But for some usages it eeds more tha these fuctioalities. Uique surface modificatio techiques ad addig high-quality materials to the core product lead to a exceptioal rage of modified citrics ad a fie-tuig of the desired fuctioality for customer applicatios. Why do we modify the properties? I certai applicatios some of the stadard product properties of citric acid are ot adequate. A modificatio of the surface provides outstadig techological beefits durig maufacturig, storage, use ad cosumptio of the products. Coatig the core material with suitable trasparet shell materials chages the physical properties of the ecapsulated product. This prevets udesired reactios with other igrediets as well as protectio agaist moisture without losig its origial fuctio. Besides surface treatmet, bledig with efficiet additives helps to keep powdered citric acid free flowig. Both modificatios have a importat ifluece o the fuctioality of the fial product. However, with a additive cotet that rages from approx. 1.5% to 4% the desired mai properties of the acid like taste, chelatig of metals or set retardig are still fully preset.

3 Fuctioal Acids Citro DC Citro DC is a direct compressible type of citric acid coated with a thi layer of maltodextri. This fuctioality avoids time ad eergy cosumig pre-processig steps before compactio. Furthermore a lower pressig force allows achievig the same hardess ad therefore eables icreasig processig speed while deficiet products are miimized. Citro DC combies high tablet stability with fast solubility i water ad is therefore maily used i effervescet tablets. Breakig stregth of effervescet tablets Citro DC Stadard citric acid 600 breakig stregth [N] pressig force [kn] Citro DC shows superiour tablet hardess ad icreased pressig force leads to harder tablets CITROCOAT N CITROCOAT N is comprised of citric acid as the core material, with a layer of a citrate as shell material. I crystallie form, it is less hygroscopic ad less reactive with other igrediets compared to regular citric acid. This provides a exceptioal stability durig storage, however solubility behavior i uchaged. CITROCOAT N is a stable, homogeeous material, which icreases the shelf life of the ed product. It is used i all applicatios, where stickiess durig processig or premature reactios with other igrediets i the dry bled (e.g. sodium bicarboate) should be preveted.

The mai advatage of citric acid S40 is its free flowig ability over a log period combied with easier hadlig compared to regular citric acid powders. Eve low amouts of 0.05 to 0.2% citric acid S40 (calculated o dry substace) improve the rheological properties of cocrete. Due to optimum dispersio ad wettig of the compoets the freshly made cocrete ad/or gypsum is easily workable, free of cracks, resistat to water ad frost with icreased mechaical stregth. It advaces the wettig of the iro reiforcemet ad reduces bleedig up substatially. Commercial available citric acid powder is usually twice as coarse compared to citric acid S40.
