Psyllium husk is the whole outer coat of the seed, and psyllium husk powder is the same husk ground fine. Hulled sesame has had its outer skin removed, while natural sesame keeps it. Kesar mango pulp comes from a Gujarat variety and Alphonso from the Konkan coast, and they differ in flavour and colour. FSG castor oil is a cleaner, lower-acidity grade than BSS.
These four pairs are often confused, so here is what separates each and what to check.
Psyllium husk vs psyllium powder
Husk is sold in flakes, graded by purity percentage. Powder is the husk milled to a stated mesh. Powder mixes and hydrates faster, which makes it useful for beverages and baking, but it is more likely to form lumps and gel in humid air. Seed, the third form, is covered in the difference between psyllium husk, husk powder and seed.
Husk purity is sold as a percentage, so make sure two suppliers measure it by the same method before you compare them. A higher figure means less foreign material, but it also means a lower yield for the mill, so it follows that purity is tied to what a supplier needs to charge.
Specify purity, mesh size, swelling volume and microbiological limits, and be clear about the end use.
Hulled vs natural sesame
Natural sesame keeps its outer hull, so it has a slightly bitter edge and a darker, matte look. Hulled sesame has had the hull removed, which gives a white, bright seed and a milder flavour. Tahini and many bakery uses call for hulled seed; some traditional products use natural.
Hulling can be done by machine or by soaking and drying, and the results differ. This is explained in the difference between machine-hulled and auto-dried hulled sesame. Ask what method is used, and check for residual hull, oil content and Salmonella.
Kesar vs Alphonso mango pulp
Kesar is grown mainly in Gujarat, and Alphonso mainly in Maharashtra and neighbouring coastal states. Both give sweet, aromatic pulp, but they differ in colour, fibre and aroma, and the difference is explained in what Kesar mango is and how it differs from Alphonso.
For a drink or dessert brand, the decision is flavour, colour and Brix, the sugar measure. Taste pulp from each variety in your own recipe, since a variety that looks right on paper may not suit your recipe. Also confirm whether the pulp is sweetened, as that changes the Brix and the label.
FSG vs BSS castor oil
FSG stands for first special grade. It is a cleaner, lighter oil with lower free fatty acid, used where colour and purity matter, such as cosmetics and personal-care uses. BSS is the lower, commercial grade, used mainly in industrial applications. The details are in what BSS grade castor oil is and how it differs from FSG.
Ask for the free fatty acid, colour, moisture and iodine value on the certificate, and name the grade and test method in the contract. Do not accept a verbal grade.
