Ingredient Substitutions NZ: Checks Before Accepting a Change

A replacement ingredient may solve a supply problem while creating a different technical question. A similar product name, the same ordering description or a supplier’s reassurance does not establish that the new material fits your formulation, controls and customer information.

This guide helps New Zealand food manufacturers, brands and other operators prepare an ingredient-substitution review before routine use. It covers the acceptance decision, evidence and implementation handover. It does not approve a particular ingredient or decide whether a changed food is safe.

Give the replacement its own identity and review status

Start with the actual manufacturer, supplier, product name, product code and specification version. Match those details to the material offered or delivered. Record the original ingredient being replaced and the products, recipes and sites where the proposed substitute would be used.

Ask for current information that fits the decision: for example, a complete composition statement, allergen information, relevant technical specification, intended-use limitations, storage instructions and the evidence your own system requires. A certificate of analysis for one batch answers a different question from a specification describing the product.

We recommend a clear status such as “awaiting technical review”, with someone responsible for preventing unintended use while questions remain. If a trial is proposed, define its boundaries and controls separately. Receipt of a delivery, a purchasing order or a salesperson’s sample is not the same as an authorised production change.

Compare the evidence before calling the materials equivalent

Use the existing approved information as the baseline, then list changes, missing information and the person who can resolve each point. Do not reduce the comparison to price and a matching headline ingredient name. The table below is a recommended review structure, not a regulator-prescribed form.

A missing field is an unresolved question rather than evidence of no change. Ask the supplier to clarify inconsistencies between a specification, label and email. Keep the response with the review record so another person can understand the decision later.

Review the control basis and the finished-product information

Have the people responsible for the process consider whether the replacement changes how the food behaves or how a control works. Ask which existing instructions, limits or supporting studies remain applicable to the new material and intended use. Where that cannot be established, define the appropriate technical work before relying on the previous conclusion.

This does not mean every supplier substitution needs a new laboratory study. The evidence needed depends on the actual difference and decision. A test result alone may not address a changed process or the whole product. Our HACCP change-review guide explains how to organise questions about existing control evidence.

For businesses using the Simply Safe & Suitable template, its current ingredient and supplier controls, hosted by Waitaki District Council include checking a changed ingredient or brand for new or additional allergens. Follow the controls in the plan or programme actually applying to your operation; the template is not assumed to cover every manufacturer.

FSANZ’s information for manufacturers, retailers and importers emphasises clear, current and accurate allergen information and management of unintended allergen presence. Compare the actual supplied material with your formulation and review relevant handling, storage and changeover arrangements. A recipe comparison alone does not resolve cross-contact questions.

Check the customer-facing information at the same time. FSANZ’s ingredient-list guidance explains listing ingredients by ingoing weight and addressing compound ingredients. The replacement’s composition may require more than changing one purchasing description. Assess the applicable declarations for the complete finished food, including ingredients within blends or premixes.

Use FSANZ’s current business allergen-labelling guidance when reviewing declarations. Preserve a supplier’s precautionary wording separately from allergens intentionally present as ingredients; do not silently turn “may contain” into “contains” or treat it as proof that a cross-contact question is resolved.

Identify every affected specification, artwork version, nutrition basis, claim and customer statement. A product already declaring one allergen still needs the wider change review. Arrange a food label review where the revised product or evidence raises a labelling question. Do not release an unsupported claim because the existing packaging is convenient.

Importers have a specific assessment responsibility

If your business is importing the changed food, MPI’s importer safety and suitability guidance requires assessment before arrival in New Zealand using relevant, current information. It says changed food needs new information and reassessment; ingredient substitutions are among the examples that may introduce new hazards or affect compliance.

Keep this importer responsibility distinguishable from a domestic manufacturer’s purchasing procedure. Identify who is the registered importer and who is gathering the assessment evidence. A manufacturing-site substitution review or an overseas supplier declaration should not be described as completing all importer obligations.

Make the internal decision usable on the production floor

Record the decision, reviewer, date, intended use and limitations. Distinguish rejection, further information required, a specifically controlled trial and acceptance for the agreed routine use. State the conditions that must be completed first rather than treating all those statuses as interchangeable.

Plan the effective point of change. Identify remaining original material, replacement lots, work in progress and the first affected finished batches. If both ingredients remain on site, make their identities and permitted uses clear. The same internal stock code can hide a meaningful difference if the supporting system cannot distinguish versions.

Update the approved recipe and relevant instructions, specifications and customer information together. Brief purchasing, receiving, production, technical and dispatch staff about the parts they own. Where a food-service menu matrix is also affected, use the separate menu allergen change checklist for that customer-information handover.

Check implementation against the defined decision: the material received, recipe issued, first applicable artwork and batch links should agree. Record discrepancies and follow the relevant hold, escalation or corrective-action procedure. A first-use check confirms the observations made; it does not independently validate every product property.

A worked example: a replacement seasoning blend

Hypothetical example only: A manufacturer receives a proposed replacement seasoning for several savoury products. Its current information identifies milk as an ingredient, unlike the previous blend. Purchasing describes it as the same seasoning type.

The technical reviewer identifies the affected recipes, compares the supporting specifications and checks product information and handling arrangements. One finished product already declares milk; another does not. Neither is automatically accepted just because one existing declaration happens to match.

The team records the unresolved questions, agrees the review work and identifies the first permitted use only after the relevant conditions are met. Original and replacement lots remain distinguishable, and staff receive the current instructions. The example shows a decision trail, not an approved recipe, safe-use finding or AFVA client outcome.

Keep a concise substitution record

• Original and replacement identities, specification versions and the reason for change.
• Affected products, recipes, processes, sites and proposed uses.
• Evidence reviewed, material differences, uncertainties and responsible reviewers.
• Decisions about controls, labels, claims and customer requirements, with supporting reasons.
• Any required authority or other external process and its actual confirmed outcome.
• The internal authorisation, limitations, effective point and affected material/finished-product batches.
• Staff handover, updated documents and the actual implementation checks.

Common errors include treating a familiar product name as equivalence, checking only the visible front label, ignoring ingredients inside blends, accepting an unsupported “no change” email, and updating the recipe while leaving older artwork or customer information in use.

Scope the review around the decision you need

AFVA’s food safety and quality consulting covers supplier and receiving records, product specifications, customer requirements and documentation review. Send the old and proposed specifications, complete formulation, affected product list, current artwork and the decision or deadline you need help with.

A food consultant can help separate supported conclusions from evidence still needed and make the implementation actions clear. Agree deliverables, specialist input and responsibilities before work starts. Consulting, laboratory analysis and any formal evaluation or verification remain distinct functions with their own scope and independence requirements.

General information only. Requirements depend on the complete activities, products, sites, programme and proposed change. Confirm current requirements and any permissions with the appropriate authority before relying on a particular registration or operating arrangement.
