Common Nameperacetic acid
DescriptionBleaching agent for food starch. Peracetic acid is a component of antimicrobial washes for poultry carcasses and fruit.Peracetic acid (also known as peroxyacetic acid, or PAA), is a organic compound with the formula CH3CO3H. This organic peroxide is a colorless liquid with a characteristic acrid odor reminiscent of acetic acid. It can be highly corrosive. Peracetic acid can be used as a bleaching agent especially for Kraft pulp. It is used at weakly acidic pH and relatively low temperature. It is a relative efficient and selective bleaching agent, and it is often used as an alternative to chlorine dioxide and elemental chlorine in totally chlorine free bleaching sequences (TCF). It is however relatively expensive, and is difficult to store due to its high reactivity. This has limited its use. Peracetic acid is a much weaker acid than the parent acetic acid, with a pKa of 8.2. Peracetic acid is an ideal antimicrobial agent due to its high oxidizing potential. It is broadly effective against microorganisms and is not deactivated by catalase and peroxidase, the enzymes that break down hydrogen peroxide. It also breaks down in food to safe and environmentally friendly residues (acetic acid and hydrogen peroxide), and therefore can be used in non-rinse applications. It can be used over a wide temperature range (0-40 °C), wide pH range (3.0-7.5), in clean-in-place (CIP) processes, in hard water conditions, and is not affected by protein residues
