Question 1

What are the food industry applications of citric acid in Oman?

Accepted Answer

Citric acid (E330) is one of the most versatile food additives in the industry, functioning as an acidulant, preservative, flavour enhancer, and chelating agent. In Oman's food and beverage sector, it is used in soft drinks and juices (the dominant acid in cola, fruit drinks, and sports beverages, providing tartness and buffering the pH for preservative effectiveness), in confectionery (sour candy coating, gummy bears), in canned and bottled foods (pH control to support thermal processing and prevent Clostridium botulinum), in dairy products (cheese making — citric acid acidifies milk before rennet addition in mozzarella and paneer production), and in seafood processing (preventing metal-catalysed oxidation and off-flavours). It is also used in cleaning formulations for descaling food equipment. Global Chemicals LLC supplies food-grade anhydrous citric acid in 25 kg bags, pallet quantities, and bulk with certificate of analysis confirming European Pharmacopoeia and JECFA food-grade specifications.

Question 2

What is the difference between food-grade and technical-grade citric acid?

Accepted Answer

Food-grade citric acid meets the purity standards specified by JECFA (Joint FAO/WHO Expert Committee on Food Additives), the European Pharmacopoeia (BP/EP), and FCC (Food Chemicals Codex) — setting strict upper limits on heavy metals (lead <0.5 ppm, arsenic <1 ppm), sulphated ash, readily carbonisable substances, and microbial counts. Technical-grade citric acid (also called industrial-grade) is manufactured to lower purity standards at reduced cost and may contain higher levels of heavy metal impurities and microbial contamination. Technical-grade citric acid must never be used in food or pharmaceutical production as the impurity profile is not controlled to a level safe for human consumption. In Oman, both grades are available in the market, and some suppliers may mislabel technical grade. Global Chemicals LLC supplies only certified food-grade citric acid with batch-specific certificates of analysis from accredited laboratories, ensuring full traceability for Oman food safety audits and FSSC 22000 / HACCP documentation.
