Registration requirements of flavouring agents
Single flavouring ingredients must be approved by the CFIA prior to their importation, manufacture, or sale, for use in livestock feeds. The approval process consists of an evaluation of each flavouring ingredient, and single flavouring ingredients that are approved and listed in Schedule V, Part I or II, of the Feeds Regulations. If possible, the maximum concentration of the ingredient to be used in feeds is established during the review.
Flavouring ingredients can be found listed in Schedule V of the Feeds Regulations, available on the Feed Program's web page on the CFIA web site. A number of flavouring ingredients are also listed in Schedule IV. Any feed ingredient that does not appear on these lists requires approval, as per Chapter 2.3 and 2.4 (Single Ingredient Feed Evaluation Requirements). Information to conduct a complete safety evaluation must be supplied as part of the new flavouring ingredient submission.
All flavouring agents require registration. Flavouring agents are generally made up of flavouring ingredients and facilitating agents, and they are present in feed at very low levels. Both flavouring and facilitating agents must be listed in either Schedule IV or V of the Feeds Regulations. Typical inclusion rates for flavouring agents are 100-1,000 g/tonne (ppm) of complete feed, with maximum levels of 3,000 g/tonne. Common flavouring ingredient levels range from 10 to 50 ppm in complete feed, while maximum use levels seen are approximately 100 ppm. When formulating a flavouring agent product, please ensure that a maximum inclusion rate for the product is selected such that none of the individual flavouring ingredients exceed their specified maximums in complete feed as per Schedule V of the Feeds Regulations, and no individual flavouring ingredient exceeds 100 ppm in complete feed.
Recognized facilitating agents (commonly called "carriers") for flavouring agents include, but are not limited to, corn, wheat, silicon dioxide, sodium carbonate, propylene glycol, and ethyl alcohol. Please note that fermentation products, and other feed ingredients such as sodium bentonite, calcium bentonite, montmorillonite clay, sepiolite, zeolite ore, or microbial products, are not considered to be acceptable facilitating agents. This is not a complete list, but it identifies the products commonly misused as carriers in flavour formulations.
The standard registration requirements include a cover letter, application form, proposed label, product formulation, and the application fee. General administrative information regarding the procedures for application for feed registration can be found in Chapter 1 (Application for Feed Registration and Ingredient Approval).
The proposed label must include the product name, reflecting the purpose of the product and the intended species; a complete list of ingredients by generic name, as listed in Schedule IV or V of the Feeds Regulations; registration numbers for any Part II ingredients or mixed feeds included in the formulation; directions for use to permit safe and effective use of the feed; a cautionary or warning statement (if applicable); the net amount (metric measure); and the name and address of the registrant.
Requirements for flavouring agents containing sodium saccharin
- A list of each intended species is required in the product name rather than stating the term "livestock" (e.g., "Flavouring agent for non-lactating dairy cattle, beef, sheep, poultry and swine feeds");
- The following cautionary statement is required on the label: "This product contains sodium saccharin, a non-nutritive sweetener which shall not be used in lactating dairy feeds".
Additional labelling requirements for liquid flavouring agents
- For liquid flavouring agents, the registrant must provide the specific gravity of the product. Please note that specific gravity does not have units and should be measured at 20°C.
- The following statement is required: "The viscosity of this product will vary inversely with temperature".
The product formulation, listing the amount of each ingredient by generic name as per Schedule IV or V of the Feeds Regulations, including registration numbers for Part II ingredients or mixed feeds, is required. The amounts of the individual ingredients in the formulation may be presented as percentages totalling 100%, or amounts comprising a total of 1,000 kg (1 tonne) of the product. Ingredient levels must not exceed maximums in complete feed as per Schedules IV and V. The applicant should include calculations verifying that the concentration of each ingredient in the flavouring agent does not exceed their respective maximum tolerance levels when the product is used at the maximum inclusion rate.
Proportion of ingredient A in flavouring agent product [2%] × maximum inclusion rate of flavouring agent product in complete feed [200 g/tonne] = inclusion rate of ingredient A in complete feed [= 4 g/tonne complete feed (or 4 ppm)]
- some maximums are specified as GMP or "Good Manufacturing Practices" in Schedule V of the Feeds Regulations. Ingredients marked with this term must be employed at a level which is appropriate for the purpose, i.e., a typical use level. As mentioned above, they must not exceed the specified 100 ppm maximum in complete feed. The same policy applies to ingredients where the maximum is specified as "". Information on typical levels may be obtained from a recognized flavour reference (e.g., Fenaroli's Handbook of Flavour Ingredients).
- all ingredients present in the flavouring agent must be stated on the formulation statement. No "and/or" statements are permitted.
- all ingredients present at a level of 0.1% or below may be declared as a range between 0% and 0.1%, but must not be 0%.
- the safety evaluation of ingredients for which a formulation range is provided will be performed using the upper limit stated in the formulation range.
- if the formulation lists previously registered products as ingredients, the registrant must ensure that these registrations are valid at the time of registration or renewal.
All formulations are treated as confidential and are protected as outlined under the Canadian Access to Information and Privacy Act.
Renewal and amendment to registered flavouring agent
As with all registered products, flavouring agents are registered for a 3-year period, renewable by March 31 of the third year after the registration date. All application(s) for renewal or amendment to a registered feed must be accompanied by an application form, appropriate fees, labels as per Chapter 1 (Application for Feed Registration and Ingredient Approval), and complete product formulation. Additional information may be requested if safety concerns emerge between the time of registration and renewal.
Changes made to the formulation of approved flavouring agents are considered new registrations and require the applicable fee (see Chapter 1). Flavouring agents submitted at the time of renewal with a change in formulation will necessitate payment of the fee for the registration of the new formulation in addition to the renewal fees.
Flavouring ingredients listed in Schedule V of the Feeds Regulations are approved as non-nutritive ingredients for use in livestock feed. Please be aware that products intended to prevent, mitigate or treat disease, or restore, correct or modify organic function in animals, may be considered drugs rather than feeds in Canada and are regulated by the Veterinary Drugs Directorate (VDD) at Health Canada.

- Conversion to a weight per weight (w/w) maximum inclusion rate, if necessary, from volume per weight (v/w) maximum inclusion rate, using the specific gravity (S.G.) provided.
S.G.: 1.10 @ 20°C
S.G. = density offlavouring agents (g/ml) / density of water (1.00 g/ml)
Maximum inclusion rate of flavouring agent (v/w)
in the Directions for Use = 1000 ml/tonne
Since mass = density × volume
Maximum inclusion rate of flavouring agent (w/w)
= (S.G. × water density) × Maximum inclusion rate of flavouring agent (v/w)
= 1.10 × 1.00 g/ml × 1000 ml/tonne
= 1100 g/tonne (ppm)
Note: For liquid flavouring agents whose "Directions for Use" are already expressed as w/w, the conversion using the S.G. is not necessary.
Example calculation of the concentration of an ingredient in the complete feed, when the flavouring agent is used at the maximum inclusion rate:
Flavouringagent inclusion rate per tonne of complete feed × %Concentrationof the ingredient in the flavouring agent = Concentrationof the ingredient in the complete feed
1100 g/tonne or 1100 ppm × 2% (0.2) vanilline = 22 ppm
