Comparing E930 - calcium peroxide vs E928 - Benzole peroxide

Overview

E930 - calcium peroxide

Calcium peroxide (E930) is an oxygen-releasing compound used mostly in flour and bakery processing. It helps strengthen dough and can lighten flour color, and it breaks down during mixing and baking into oxygen and calcium compounds. It is listed as a permitted food additive in several regulatory systems.

E928 - Benzole peroxide

Benzole peroxide (also known as benzoyl peroxide) is a flour treatment agent used mainly to bleach and standardize the color of wheat flour and certain dairy ingredients. In food processing it breaks down as it works, leaving little to no active residue in the finished product under approved uses.

Popular questions

  1. Calcium peroxide – what it is: bleaching agent and dough conditioner?

    Calcium peroxide (E930) is a synthetic flour treatment agent that releases oxygen, acting as a bleaching agent to whiten flour and as a dough conditioner to strengthen gluten and improve texture. It is used at very low levels and is almost insoluble in water.

  2. Calcium peroxide how long has this chemical been around?

    It has been known since the early 20th century, with food-related uses (e.g., flour treatment) established for several decades. Its approval and use vary by country.

  3. How do you use baking soda and peroxide on granite counter tops to remove calcium?

    That method typically refers to hydrogen peroxide, not calcium peroxide (E930); calcium peroxide is a food additive and not intended for stone cleaning—use granite-safe cleaners per the manufacturer’s guidance.

  4. How do you use baking soda and peroxide on granite countertops to remove calcium?

    This refers to hydrogen peroxide rather than calcium peroxide (E930); the food additive isn’t suitable for cleaning granite, so follow stone-care products and instructions instead.

  5. How do you use dental calcium peroxide paste with idofrm?

    Dental pastes commonly use calcium hydroxide with iodoform, not calcium peroxide; E930 is a flour treatment additive and should not be used for dental applications—follow product labeling or a dentist’s guidance.

  1. How does benzole peroxide reduce acne?

    As a topical drug, benzoyl peroxide reduces acne by releasing oxygen that kills acne-causing bacteria and helps keep pores from clogging; as a food additive (E928) it’s used to bleach flour, not to treat acne.

  2. How does benzole peroxide work?

    In foods, benzoyl peroxide (E928) is a strong oxidizing flour-bleaching/maturing agent that whitens flour pigments and then breaks down mainly to benzoic acid and oxygen.

  3. How to prevent bleached eyebrows benzole peroxide?

    Because it’s a bleaching oxidizer, keep products away from hair/eyebrows, apply carefully, use a barrier (e.g., petroleum jelly) along the hairline, and rinse hands and any residue off promptly.

  4. How to use benzole peroxide?

    In food processing, small regulated amounts are uniformly blended into flour to bleach and mature it; for topical acne products, follow the label and start with lower strengths due to irritation and bleaching risk.

  5. What store sells benzole peroxide shampoo?

    Benzoyl peroxide is uncommon in human shampoos (it can bleach hair) and is mainly sold as acne washes at pharmacies or online; as E928 it’s an industrial flour-bleaching aid, not a consumer shampoo.
