How to compare almond hulls and hull-and-shell analysis

Start with what the lot contains

An analysis sheet cannot tell you what an almond co-product contains unless the product description is clear. Almond hulls are the fleshy outer material removed from almonds during processing. A hull-and-shell product includes some of the hard, woody shell as well. Those materials are not interchangeable descriptions: shell content changes the physical and nutritional composition of the lot.

Ask the seller to state whether the offer is hull-only or hull-and-shell, and how that description is defined for the specific lot. A product name alone may not explain how much shell or other woody material is present. Treat the description and the laboratory analysis as complementary: one identifies the material being offered; the other characterizes a sample of it.

Read fiber and ash as clues, not proof

Fiber can help distinguish lots because hard shell and other woody material contribute structural plant matter. If one offer has higher fiber than another, shell content may be one explanation—but it is not the only one. Differences in the hull material, processing, sampling, analytical method or reporting basis can also affect comparisons. Fiber results by themselves do not establish how much shell a lot contains.

Ash is the mineral residue left after a sample is burned in an analytical test. It can be useful when comparing lots, but it does not identify shell content specifically. Mineral matter from soil or other extraneous material can also affect ash. A result that differs from your expectations is a reason to clarify the product and review the full analysis, not a stand-alone verdict about purity.

If shell content matters to your formulation or handling, request a clear product description and ask whether the seller can provide a separate description or measure of shell content. Do not infer a precise hull-to-shell proportion from fiber or ash unless that relationship is expressly established for the lot.

Make analytical basis and methods comparable

Before comparing numbers, check whether results are reported as-fed or on a dry-matter basis. As-fed values describe the material with its moisture included. Dry-matter values remove the effect of moisture, making them more useful for comparing nutrient concentrations across samples with different moisture levels. Comparing an as-fed result with a dry-matter result can make otherwise similar lots appear different.

Also check that each analysis identifies the test method or laboratory basis where available, and that the reported results refer to the offered lot rather than a general product description or historical sample. Make sure you are comparing the same measure under the same reporting convention. If the basis is missing or unclear, request clarification before using the numbers in a purchasing or formulation comparison.

Use the rest of the analysis to understand the lot

Moisture helps you compare the material as received and consider its storage and handling. Soluble sugars can help distinguish lots in terms of readily available carbohydrate; protein and fat add further context about composition. These measures do not, on their own, identify hull-only versus hull-and-shell material, but together they provide a fuller basis for comparing offers.

Review the measures against the intended ration and the requirements set by your nutritionist or feed program. Pay attention to whether each result is reported as-fed or on a dry-matter basis, and whether results come from a representative, lot-specific analysis. Published examples or ingredient-definition limits should not be treated as a guaranteed specification for a commercial offer.

Build a practical comparison before buying

Put the product description, analysis basis and lot results side by side. Record whether the material is described as hulls or hull-and-shell; compare fiber and ash as indicators that merit follow-up, not definitive shell tests; then review moisture, soluble sugars, protein and fat using consistent bases. Note any missing method, sample date or lot identification so that gaps do not disappear in a spreadsheet.

For a useful quote, specify the material description you need, quantity and unit, destination, timing, and any analysis or packaging requirements relevant to your receiving setup. Ask for the analysis tied to the offered lot and resolve differences in terminology or reporting basis before comparing price. Once those requirements are clear, visit the [Almond Hulls sourcing page](/ingredients/almond-hulls) to pursue an offer.
