Acetylated Oxidized Starch (E/INS 1451): Properties, Uses, and Regulations

Starch is a complex carbohydrate made up of many glucose units linked together by alpha 1-4 glucosidic bonds. It exists in two forms: linear (amylose) and branched (amylopectin), where the latter is formed by alpha 1-6 glucosidic bonds. Each glucose unit in starch has three hydroxyl groups that can undergo chemical modification.

Acetylated oxidized starch is a modified starch. It is obtained by treatment of food starch with sodium hypochlorite followed by esterification with acetic anhydride in accordance with good manufacturing practice (GMP). Oxidation involves the deliberate production of carboxyl groups. Acetylation results in substitution of hydroxyl groups with acetyl esters.

Acetylated oxidized starch may additionally be subjected to acid, alkali, enzyme, or bleaching treatment in accordance with good manufacturing practice.

General Standard for Food Additives (GSFA) Provisions for Acetylated Oxidized Starch (E/INS 1451)

The Codex General Standard for Food Additives (GSFA) establishes the conditions for the use of Acetylated oxidized starch in foods, regardless of whether they have been previously standardized by Codex.

*Note: Unless otherwise specified, food additive provisions apply to the food category indicated (e.g. Dairy), as well as to all subcategories of that category (e.g. Cheese, Ripened Cheese, etc.).

Based on the Codex General Standard for Food Additives (GSFA), acetylated oxidized starch can only be used in complementary foods for infants and young children.

Complementary foods for infants and young children:

Foods that are intended for infants 6 months of age and older, and for progressive adaptation of infants and children to ordinary food. Products may be ready-to-eat or in powder form to be reconstituted with water, milk, or other suitable liquid. These foods exclude infant formulae, follow-up formulae, and formulae for special medical purposes. Examples include: cereal-, fruit-, vegetable-, and meat-based “baby foods” for infants, “toddler foods,” and “junior foods”; lactea flour, biscuits and rusks for children.

Max Level: 60,000 mg/kg

Notes:

  • Singly or in combination with other modified starches used as thickeners In products conforming to the Standard for Canned Baby Foods (CODEX STAN 73-1981).
  • Excluding products conforming to the Standard for Processed Cereal-Based Foods for Infants and Young Children (CODEX STAN 74-1981).

GSFA Table 3 Provisions for Acetylated Oxidized Starch (E/INS 1451)

Acetylated oxidized starch is a food additive that is included in GSFA General Conditions of Table 3, and as such may be used in the following foods under the conditions of good manufacturing practices (GMP) as outlined in the Preamble of the Codex GSFA. Although not listed below, Acetylated oxidized starch could also be used in heat-treated butter milk (in Fluid milk (plain)) and spices (in Herbs and spices). Note that food categories listed in the Annex to Table 3 were excluded accordingly.

Acetylated oxidized starch is acceptable in foods conforming to the following commodity standards: CS 249-2006.
