How Do You Use Hydrogenated Glycerides?


***Update: CFD does not sell any of these products. Check with other fat suppliers to see if what you buy is a hydrogenated glyceride.

As an AFIA member, CFD has received a request to assist the American Feed Industry Association in the identification of how Hydrogenated Glycerides are used in our industry. Please let me know if and how you use these products so I can provide feedback to AFIA. Email the information to Your quick response is appreciated as discussions with AAFCO will be held in the next few weeks. The following important information was provided by AFIA last week…

“The Issue:

This summer, the Food and Drug Administration’s Center for Veterinary Medicine staff realized that the definition for hydrogenated glycerides in the AAFCO Official Publication (OP) did not contain all the information that was agreed upon by CVM when the definition went through the ingredient review process in 2012. In particular, the definition unintentionally left off the intended use and inclusion rate. AAFCO approved and published the incorrect version of the definition, which did not restrict any uses of the product, in the 2012-2017 OPs.

The AAFCO Ingredient Definitions Committee took action at its August meeting to correct the definition to limit the use of the product to what CVM originally approved as part of the ingredient submission in 2012. The product is only meant to be used as a binder and lubricant in the pelleting of feed (i.e., as a pelleting aid) for all animal species. The maximum inclusion rate is four pounds per ton of finished feed. Since the product was approved only as a pelleting aid, the ingredient was also moved out of the “fats and oils” section into the “technical additives” section and renumbered.

The modified definition (as taken from the AAFCO IDC minutes) now reads (new language is bolded):

T73.311 (old 33.19) Hydrogenated Glycerides are obtained by hydrogenation of animal fats or vegetable oils. They are used solely as a binder and lubricant in pelleting of feed (pelleting aid) of all animal species. Maximum inclusion rate is 4 lb per ton of finished feed. Specifications of animal fats or vegetable oils used to produce the hydrogenated glycerides must meet the requirements stated in AAFCO definition 33.1(for Animal Fat) and AAFCO definition 33.2 (for Vegetable Fat, or oil), respectively. The specification for tallow must specify insoluble impurities not more than 0.15% to be consistent with BSE feed regulation 21 CFR 589.2000 and 589.2001 and a guaranteed titer above 40°C. The source of the hydrogenated glycerides must be indicated on the label. The hydrogenated glycerides must contain, and be guaranteed for, not less than 90% total ester content, not more than 0.8% unsaponifiable matter, not more than 0.001% heavy metals, and not more than 5 of iodine value. The maximum moisture, maximum insoluble matter, maximum free fatty acids, saponification value, and melting range must also be guaranteed on the label. If an antioxidant is used, the common name or names must be indicated on the label, followed by the words “used as a preservative.” (Proposed 2012, Adopted 2015, renumbered & edited 2018)

CVM and AAFCO sought to delete the current definition as published in 33.19, but AFIA urged them to delay until the animal food industry could be informed of the modification and assess the impacts this change would have on the industry.

AFIA has been told that this definition will be deleted at the January AAFCO meeting if industry does not come forward before the meeting with information to modify the definition.

The Need:

According to the CVM, the original definition for hydrogenated glycerides was based upon the use of the product as a pelleting aid. If you manufacture or distribute animal or vegetable fats or oils that are produced through hydrogenation (either through full or partial hydrogenation), and it is used for an intended use other than as a pelleting aid, your product is not defined in AAFCO. Any use of hydrogenated glycerides other than as a pelleting aid is also not defined in AAFCO. To continue using these products, new definitions will need to be approved and published by AAFCO.”
