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.

Overview

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.

nn

Calcium 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.

nn

Potassium 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.

Where it's used
  • Anti-caking and free-flow in salt, seasonings and powdered blends (calcium silicate)
  • Clarification of beverages, oils and syrups with diatomaceous-earth filter aid
  • Alkalization and clean-in-place caustic cleaning with potassium hydroxide
  • pH buffering and flow with magnesium oxide; calcium mineral input with coral calcium
  • Standardized yellow-orange coloring with beta-carotene
Frequently asked questions
What mineral processing aids does RawSource supply for food and beverage?
RawSource sources calcium silicate (anti-caking), flux-calcined diatomaceous earth (filter aid), magnesium oxide and potassium hydroxide (inorganic bases for pH control and alkalization), coral calcium (a calcium mineral and flow additive), and beta-carotene (a carotenoid colorant).
Is diatomaceous earth used as a filter aid or as a filler in food?
In food and beverage it is used as a filter aid. Flux-calcined diatomaceous earth forms a porous filter cake that clarifies beverages, oils and syrups by trapping haze and fine solids. It is a processing aid, not a nutritional filler.
Does RawSource supply food-grade potassium hydroxide and calcium silicate in bulk?
Yes. These minerals and bases are available in drums, totes and bulk with full SDS, TDS and COA documentation. Confirm the required food-grade or FCC specification and the regulatory status for your application and jurisdiction.
What is the difference between potassium hydroxide and magnesium oxide for pH control?
Potassium hydroxide is a strong caustic that neutralizes quickly and completely but is corrosive and needs controlled dosing. Magnesium oxide is a milder, slower alkaline buffer that also acts as a flow aid and supplies magnesium. Choose by the pH target and the handling controls available.
