Inosinic acid

Inosinic acid (CAS 131-99-7), traded as inosine monophosphate (IMP) and approved as E630, is a nucleotide used mainly as a flavor enhancer in food manufacturing.

Where is Inosinic acid used?

• Food manufacturing: umami amplification at low use levels, often with other nucleotides or glutamates
• Processed food: combined with monosodium glutamate or disodium guanylate
• Soups, seasonings, snack coatings and instant noodles: boosted umami intensity
• Meat processing and bouillon: broth-like depth in powdered stocks, sauces and ready meals
• Biotechnology: biochemical reference material and substrate
• In nucleotide metabolism research and nucleotide-based preparations it serves as a precursor or active component.

Good to know: The disodium salt form is most common for food applications.

Commercial specifications

• Food-grade material meets E630 specifications
• Bulk quantities standard for food ingredient buyers; smaller pack sizes for laboratory use
