Inorganic processing minerals and bases u2014 calcium silicate anti-caking, diatomaceous-earth filter aid, magnesium oxide and potassium hydroxide u2014 plus beta-carotene color, for free-flow, clarification, alkalization and coloring.
Mineral fillers and pigments in food and beverage are inorganic processing aidsnu2014 they make a product manufacturable rather than flavor or fortify it. This familyncovers two jobs: free-flow and filtration aids (calcium silicate, diatomaceous earth) thatnkeep powders flowing and clarify liquids, and inorganic bases (potassium hydroxide,nmagnesium oxide) used for alkalization and pH control. Beta-carotene rounds out the group asna carotenoid colorant. Select by function; an anti-caking agent and a caustic base solvendifferent problems.
nnCalcium silicate adsorbs surface moisture and is dosed at a few percent to keep salt,nseasonings and powdered blends free-flowing. Flux-calcined diatomaceous earth works as anfilter aid, clarifying beverages, oils and syrups by forming a porous filter cake. Forncaking control, add calcium silicate at the blending stage; for haze removal, build andiatomaceous-earth precoat on the filter. Confirm the food-grade specification for yournjurisdiction before use.
nnPotassium hydroxide and magnesium oxide are the inorganic bases. KOH is a strong causticnfor alkalization (cocoa, olives) and clean-in-place cleaning; magnesium oxide is a mildernalkaline buffer that also aids flow. The trade-off is handling: KOH gives fast, completenneutralization but is corrosive and needs controlled dosing, while magnesium oxide isngentler and slower. Beta-carotene supplies a standardized yellow-orange shade. Match thenbase to the pH target and the safety controls available.
