E162: Beetroot Red (Betanin) vs. E338: Phosphoric Acid (Cola Acidulant)
Comparing 2 standards across 9 specifications. 9 key differences identified.
E162 (Beetroot Red / Betanin) is a water-soluble red-purple betacyanin pigment pressed or extracted from red beets (Beta vulgaris). INS 162, ADI is Not Limited (Quantum Satis), used in dairy, ice creams, and sausages.
E338 (Phosphoric Acid / H3PO4) is a mineral inorganic acid providing a uniquely dry, tangy, astringent sourness. INS 338, group ADI is 40 mg/kg bw/day (as phosphorus), the quintessential acidulant in cola beverages and processed cheeses.
