OEM/ODM Plant Protein Supplements: Blend Ratios & Composition

State the reason for combining proteins

Plant protein blending can address amino acid composition, flavor, texture, cost, or supply continuity. These are different objectives, and a ratio that solves one may make another harder. Put the priority in the brief before selecting ingredients, so a purchasing compromise does not quietly become a nutrition claim.

Start with two fully identified grades and their analytical records. A familiar pea-and-rice pairing is a development option, not a universal recipe. Research has examined how processing affects those proteins, reinforcing the need to consider commercial grade and processing history beside the source name.

Calculate the ratio on the correct basis

An equal weight mixture is not necessarily an equal protein mixture. In a hypothetical example, 10 grams of an 80% protein powder contributes 8 grams of protein, while 10 grams of a 70% powder contributes 7 grams. The ingredient ratio is 50:50, but the protein contribution is 8:7.

Use compatible as-received assay values when preparing a batch formula. If supplier profiles are expressed per gram of protein, calculate each component contribution before summing amino acids. Keep the worksheet readable enough that a substitute supplier or changed assay can be evaluated without reconstructing the original assumptions.

Do not turn a calculated profile into a quality score

FAO distinguishes amino acid composition from protein quality evaluation that also considers digestibility. A spreadsheet showing a balanced set of amino acids is useful for sourcing, but it is not by itself a measured digestibility result or authorization for a finished-product nutrition claim.

If a protein quality statement is important to the US label, obtain qualified review of the applicable calculation and evidence. Keep research ingredient, blend ratio, preparation, and population details visible. A published finding on one blend cannot simply be transferred to a different flavored formula.

Run a ratio screen at constant protein contribution

Choose several plausible blend ratios and keep the target protein contribution and preparation volume fixed. Record the resulting total powder mass, sweetness requirement, color, and mouthfeel. This makes it possible to see whether a theoretically attractive profile creates an inconvenient serving or an excessively thick shake.

Evaluate each blend immediately and after standing, using the same vessel and mixing energy. Observe foam, sediment, clumps, and flavor persistence separately. Where a ready-to-drink process is proposed, add the actual heat and acidity conditions before selecting a winner from the dry-blend comparison.

Protect the approved ratio during production

Differences in particle size and density can affect powder handling, so assess the whole blend during transfer and filling. Decide how to sample the trial and how to verify the relevant compositional targets. A container that looks uniform is not proof that its ingredient distribution stayed consistent.

Record each accepted grade and the permitted substitution process. If one protein becomes unavailable, repeat the necessary composition and application checks rather than matching total ingredient weight alone. The approved ratio belongs to defined materials; it does not guarantee identical performance with any protein from the same plants.

Compare manufacturing considerations for your intended product. Suitability depends on the complete formulation.
