Standard of Identity for Food: When a Name Has a Recipe

Standards of identity: why peanut butter, jam, mayonnaise, ice cream and maple syrup must meet FDA's numbers to use the name, the other names, a checker.

Some food names come with a recipe written into federal rules. FDA's standards of identity, in 21 CFR parts 130 to 169, say what a food has to be to carry its name: peanut butter is ground roasted peanuts with no more than 10% seasonings and stabilizers, jam is at least 45 parts fruit to 55 parts sugar and 65% soluble solids, mayonnaise is at least 65% oil, ice cream has at least 10% milkfat and weighs at least 4.5 pounds a gallon, and maple syrup is at least 66% soluble solids. A food sold under one of those names that doesn't meet the standard is misbranded, whatever its label says otherwise. The fix is a different name: a peanut butter with too much honey becomes a peanut spread, a low-sugar jam a fruit spread, a mayonnaise short on oil a dressing, and an ice cream short on milkfat a frozen dessert. One exception: a food that misses the standard only in a way a defined nutrient claim describes, such as reduced fat, can keep the name with the claim. And foods without a standard, like almond butter, use their common name. In the example below, an Arkansas nut butter maker checks which jars can be called peanut butter.

The short version

  • A standard of identity sets what a food must be to use its name.
  • Peanut butter: seasonings and stabilizers 10% or less, fat 55% or less, stabilizing oils hydrogenated.
  • Jam: 45 parts fruit to 55 sugar, 65% soluble solids. Mayonnaise: 65% oil.
  • Ice cream: 10% milkfat, 4.5 lb a gallon. Maple syrup: 66% soluble solids.
  • Miss the standard, change the name: peanut spread, fruit spread, dressing, frozen dessert.
  • A defined claim like "reduced fat" can keep the name; unstandardized foods use their common name.
  • TaroStack keeps each recipe by weight, so the share of honey in a batch is on record. More below.

Some standards small makers meet

Food The numbers If it misses
Peanut butter Seasonings and stabilizers 10% or less; fat 55% or less; stabilizing oils hydrogenated Peanut spread
Jam 45 parts fruit to 55 sugar (47 for Group I fruits); soluble solids 65% Fruit spread
Mayonnaise Vegetable oil 65% by weight Dressing
Ice cream Milkfat 10%; total solids 1.6 lb and weight 4.5 lb a gallon Frozen dessert
Maple syrup Soluble solids 66% Boil it further

Ketchup, cheese and chocolate have their own standards, in ketchup business plan, cheese labeling requirements and chocolate labeling requirements.

The rules

Rule Where
The name and the standard A food represented as a standardized food must conform and bear the standard's name (21 U.S.C. 343(g))
Peanut butter Seasonings and stabilizers 10% or less; fat 55% or less; no artificial flavors or sweeteners, preservatives or colors; stabilizing oils hydrogenated (21 CFR 164.150)
Jam, mayonnaise, ice cream, maple syrup 21 CFR 150.160, 169.140, 135.110, 168.140
Nutrient claims A deviation described by a defined nutrient claim keeps the name with the claim (21 CFR 130.10)

This is general information, not legal advice.

An example: six jars

Red Oak Nut Butters, the made-up nut butter maker in Little Rock, Arkansas, I use in these examples, was changing its honey roasted recipe and checked every jar against the peanut butter standard:

Jar Seasonings and stabilizers Fat Other conditions Name
Peanuts only 0% 50% Met Peanut butter
Peanuts and salt 1% 50% Met Peanut butter
Honey roasted, first recipe 11%: 10% honey, 1% salt 48% Met Peanut spread
Honey roasted, new recipe 9.5%: 8.5% honey, 1% salt 48% Met Peanut butter
No-stir, with palm oil 4% 51% Palm oil isn't hydrogenated Peanut spread
Chocolate peanut 18.5% 44% Met Chocolate peanut spread

The honey roasted had been labeled peanut butter at 11%, a point over the line, so the new recipe cut the honey to 8.5% to keep the name. The no-stir jar is well under 10%, but its palm oil isn't a hydrogenated oil, so it's sold as a peanut spread. The almond butter needs no checking: there's no standard for it. Which jars can say "healthy" is in healthy claim FDA.

Download the standard of identity checker. Two sheets. Check: each product, the standard it would be named for, its measures and whether its other conditions are met; whether it meets the standard and what to call it if not fill in. Measures: what to measure for peanut butter, jam, mayonnaise, ice cream and maple syrup, the numbers and the regulation. It's an ordinary Excel file with no macros, and it works in Google Sheets, LibreOffice and Numbers.

Where this stops working

The name is right for the recipe on file. A heavy-handed batch of honey roasted, 10.5% instead of 9.5%, is a peanut spread in a peanut butter jar, and only the batch record shows how much honey went in.

How TaroStack does it

TaroStack keeps each recipe by weight, so the share of honey in a batch is on record.

Recipes by weight. Each jar is its own recipe, with its peanuts, honey, salt and oil by weight.

Batches by lot. Each batch records which ingredient lots it used and how many jars it made.

Recalls. If a batch went out under the wrong name, one report shows every customer who got it.

The job Notebook In TaroStack
Which recipe a batch followed Remembered Each batch from its recipe
Honey used in a batch Not recorded From the recipe and batch
Who got a mislabeled batch Invoices One recall report

Recipes, batches and recalls are on every plan, from $49 a month. The first 30 days are free, with no credit card. If you'd like a hand setting up, ask, and we'll do it with you.

Questions people also ask

What is a standard of identity?

A federal rule that sets what a food must contain to be sold under its name, such as peanut butter, jam or ice cream.

What is the difference between peanut butter and peanut spread?

Peanut butter meets FDA's standard: no more than 10% seasonings and stabilizers and 55% fat; a peanut spread doesn't.

Why is it called fruit spread and not jam?

Jam has to meet a standard of 45 parts fruit to 55 parts sugar and 65% soluble solids; a lower-sugar product can't use the name.

Does every food have a standard of identity?

No: many foods, like almond butter, have none and use their common or usual name.
