How to compare peanut granule size and fines

Why particle size matters

Peanut granules are pieces of peanut kernel, and their size distribution affects how they look and feel in a finished food. Larger pieces create more visible inclusions and a more pronounced bite; smaller particles blend more readily into a product. The right balance depends on the role the granules play in the recipe.

Fines are the smaller particles present alongside the main granule sizes. A higher share can make a blend look dustier or less uniform, and may change the texture consumers notice. Fines are not automatically a defect: they can be acceptable or useful in some formulations. The important question is whether their amount and particle range suit the product and process.

Read the distribution, not just the size label

A label such as “small” or “coarse” is not enough to compare two offers unless the terms are defined the same way. Ask how the specification describes the particle-size distribution: it may give size bands, screen or sieve results, or another defined measure. Look for the proportion assigned to each band, including the smallest fraction, rather than relying only on a nominal or average size.

The measurement method matters because results depend on how the sample is separated and reported. Check the screen or sieve sizes used, whether results are expressed as retained or passing fractions, and how the test handles particles that break during preparation. If two documents use different methods or reporting conventions, their figures may not be directly comparable. Do not infer a size range from a product name; use the actual specification.

Connect size and fines to the finished food

In chocolate, granule size influences the visibility and bite of peanut pieces. A manufacturer seeking distinct inclusions will evaluate the larger fractions and the consistency of the distribution; excessive fine material could change the appearance of the mix or contribute a less defined texture. The preferred profile depends on the product design and the point at which the granules enter the process.

In biscuits and other baked foods, particle size affects how evenly inclusions appear across a batch and how noticeable they are in each bite. Fine particles may distribute differently from larger pieces and can affect the finished product’s texture. Bench or line trials can help establish which distribution works in the actual recipe; a specification by itself cannot determine the sensory result.

Compare specifications and lot documents

Start with the product specification. Compare the stated size bands, the reported share in each band, the method used, and any stated tolerance or limit for fines. Check that the document identifies the product and that its terminology is clear. If “fines” is not defined, ask what particle size or test result the term refers to before using it to compare offers.

A lot-specific certificate of analysis or sieve-analysis report can show how a particular lot was assessed, when such documentation is available. Compare its results with the specification and note the method, sample or lot identification, and units or reporting basis. A general specification describes the intended product; a lot document reports results for a specific lot. These documents serve different purposes and should not be treated as interchangeable.

There is no universal fines limit or granule-size profile for every food application. Set acceptance criteria around your product’s visual and textural requirements, then compare offers against the same definitions and test basis. When you are ready to source a defined size, visit the Peanut Granules page and specify the distribution and fines information your process needs.
