§ 102.23 Peanut spreads.
（a） The common or usual name of a spreadable peanut product that does not conform to §164.150 of this chapter, and more than 10 percent of which consists of nonpeanut ingredients, shall consist of the term “peanut spread” and a statement of the percentage by weight of peanuts in the product in the manner set forth in §102.5（b）, except that peanut percentages shall be based on the amount of peanuts used to make the finished food and shall be declared in 5-percent increments expressed as a multiple of 5, not to exceed the actual percentage of peanuts in the products.
（b） A spreadable peanut product that is nutritionally inferior to peanut butter shall be labeled as an imitation of peanut butter under §101.3（e）（2） of this chapter; a spreadable peanut product shall be considered nutritionally equivalent to peanut butter if it meets all of the following conditions:
（1） Protein. （i） The protein content of the product is at least 24 percent by weight of the finished product, and the overall biological quality of the protein contained in the product is at least 68 percent that of casein; or
（ii） The protein content of the product is at least 16.6 percent by weight of the finished product, and the overall biological quality of the protein contained in the product is equal to or greater than that of casein.
（2） Other nutrients. The product contains the following levels of nutrients per 100 grams of product:
| Nutrient | Amount (milligrams) |
| Niacin | 15.3 |
