What this category is actually bought on
A plant protein specification opens with a percentage, and that percentage is the least reliable basis for comparison in the whole document. Protein is measured as nitrogen and converted with a factor, on a moisture basis that is not always stated. Two ingredients quoting the same figure can differ by real percentage points, and they will differ far more than that in solubility, gelation and flavour.
The second thing this category is bought on is the label. Whether an ingredient brings a mandatory allergen declaration, a genetically modified organism question or a deforestation due diligence obligation is often the decisive commercial factor, and it has nothing to do with the analytical specification at all.
The product records
Soy protein isolate and pea protein are the two dominant protein bases, and the choice between them is rarely about protein content. Sunflower lecithin is the emulsifier that removes a soy declaration from a formulation without changing what the emulsifier does. Coconut flour is the high-fibre speciality flour in the group, and the one where the gluten-free claim is a supply chain question rather than a botanical one.
The decisions behind the specification
Plant-based protein sourcing decodes the protein figure, sets out the flour, concentrate and isolate tiers, and lists the documentation to require. Soy against pea protein takes the two dominant options through functionality, labelling, supply chain and cost. Allergen management in mixed facilities covers the site controls behind any allergen position a supplier states.
Where Vorezan sits
Vorezan is an information resource, not a seller, a broker or a certifier. These pages set out how the category is specified and traded so that a buyer can write a better contract and ask better questions. They do not replace the consolidated text of any legal instrument, the current revision of any trade reference, or professional advice on a specific consignment.
