Comparing E320 - Butylated hydroxyanisole (bha) vs E315 - Erythorbic acid

Overview

E320 - Butylated hydroxyanisole (bha)

Butylated hydroxyanisole (BHA), also labeled as E320, is a synthetic antioxidant used to keep fats and oils from going rancid. It helps protect flavor, color, and texture in many shelf‑stable foods. You will usually see it listed as “BHA” or “E320” on ingredient labels.

E315 - Erythorbic acid

Erythorbic acid (E315), also called isoascorbic acid, is an antioxidant used to keep foods fresh-looking and flavorful. It slows down browning and rancidity, especially in cured meats and processed foods, and helps protect color and taste during storage.

    Yes—salicylic acid is a BHA (beta hydroxy acid) used in skincare and is not the same as the food additive BHA (E320, butylated hydroxyanisole).

  4. What is bha and bht?

    BHA (E320, butylated hydroxyanisole) and BHT (E321, butylated hydroxytoluene) are synthetic antioxidants added to foods and packaging to prevent oxidation and extend shelf life.

  1. How does erythorbic acid work?

    It acts as a reducing agent (antioxidant), donating electrons to quench oxygen and free radicals, thereby slowing oxidation. This helps protect color, flavor, and nutrients in foods.

  2. How does erythorbic acid work as a preservative?

    It prevents oxidative spoilage by scavenging oxygen/free radicals and maintaining pigments (e.g., cured meat color), reducing rancidity and discoloration. It is not antimicrobial, so it doesn’t directly inhibit bacteria.

  3. How is erythorbic acid made?

    It’s produced synthetically (e.g., from methyl 2‑keto‑D‑gluconate with sodium methoxide) or via microbial/fermentation routes from sugars like sucrose using selected strains (e.g., Penicillium), then converted to erythorbic acid.

  4. How to change language for bluetooth wireless headset lifecharge e315?

    E315 here denotes erythorbic acid (a food antioxidant), not a headset model—please check your headset’s manual or the manufacturer’s support site for language-setting instructions.

  5. How to change language for headset lifecharge e315?

    E315 refers to erythorbic acid as a food additive, not a headset; consult the device manual or manufacturer support for how to change the headset’s language.
