Dehydroacetic acid

International Numbering System (INS) for Food Additives: 265

Food additives Europe numbers:E265 

Dehydroacetic acid (DHA) can be a food excipient, but its use is limited due to some safety considerations. Here's a breakdown of its properties:

Properties:

• DHA is a broad-spectrum preservative, meaning it can inhibit the growth of various microorganisms like mold, yeast, and bacteria.
• It's a beige to light yellow crystalline powder with a slightly sour odor.
• It's thermostable (heat resistant) and remains effective even after cooking.

Use in Food:

• DHA has potential benefits as a food preservative, but its use is generally discouraged and strictly regulated due to safety concerns.
• Some studies have raised concerns about its potential genotoxicity (ability to damage DNA).
• Regulatory bodies like the FDA have limitations on its use in food. In the US, for example, it's not typically approved as a direct food additive.

Limited Applications:

• There might be some specific permitted applications for DHA in certain countries, but generally under very low concentration levels.
• An example might be its use on the surface of cut or peeled squash to prevent spoilage, but with limitations on the residual amount remaining on the edible part.

Alternatives:

There are other preservatives generally recognized as safe (GRAS) by the FDA and other regulatory bodies that are preferred for food applications. These alternatives offer similar benefits without the same safety concerns as DHA. Examples include sorbic acid and propionic acid
