What it does
Schedule 14 of the Australia New Zealand Food Standards Code is a definitional instrument that exhaustively lists the technological purposes that a substance must serve to be classified as a “used as a food additive” or “used as a processing aid” under the Code. It does not itself authorise any substance or set maximum permitted levels; those functions reside in other standards (principally Standard 1.3.1 for food additives and Standard 1.3.3 for processing aids). Instead, Schedule 14 performs a gatekeeping role: a substance can only be a food additive or processing aid if its function falls within one or more of the 22 purposes set out in the table to S14,2. The table defines each purpose with a short, functional definition and, in many cases, includes sub-classes that further clarify the scope. For example, “Acidity regulator” is defined as “alters or controls the acidity or alkalinity of a food” and includes sub-classes such as “acid”, “alkali”, “base”, “buffer”, “buffering agent”, and “pH adjusting agent”. The schedule also distinguishes between purposes that might otherwise be conflated, such as “Flavour enhancer” (enhances existing taste or odour) and “Flavouring” (intense preparations added in small amounts to impart taste or odour, but excluding herbs, spices, and substances with exclusively sweet, sour, or salt taste). By providing these definitions, the schedule gives legal certainty to manufacturers, importers, and enforcement agencies about which functions are recognised under the Code. It also prevents category creep: a novel or innovative function not captured by any listed purpose cannot be used to justify the addition of a substance as a food additive unless the schedule is amended. The instrument therefore directly shapes the product development and reformulation choices available to food businesses, and it imposes a fixed taxonomy that must be matched to any additive’s claimed effect. The schedule is a standard under the Food Standards Australia New Zealand Act 1991 (Cth) and applies in both Australia and New Zealand, with New Zealand adopting it under its Food Act 2014. It came into force on 1 March 2016 and has been amended only twice, both times to correct typographical errors in the table. This stability means that the taxonomy of purposes has remained unchanged since the schedule’s inception.
