Bloom, mesh & origin:
a gelatin buyer's
vocabulary.
Five words decide most gelatin purchasing decisions. Get them right and your formulation behaves predictably. Get them wrong and you'll spend the next quarter wondering why your gummies are weeping or your capsules are cracking.
decide how gelatin
behaves in your line.
Gelatin is bought on a handful of numbers, and most of the trouble in the category comes from treating those numbers as a price ladder rather than a functional specification. A bloom value is read as a quality grade. An origin is assumed. A mesh size is copied from the last order. The terms below are the vocabulary that actually governs how a batch performs on your line - what each one means, where it bites, and what the line is really telling you when it shows up on a Certificate of Analysis.
Bloom
Bloom measures gel strength: higher bloom means a firmer set. Confectionery typically uses 180–250 bloom; pharmaceutical capsules often 150–250; some technical uses go higher. The critical point buyers miss is that bloom is not a quality grade - it is a functional spec. A 220 is not "worse" than a 250; it is a different tool. Always measured on the standard 6.67% solution chilled to 10°C - a bloom value without that method isn't a number.
Mesh
Mesh is the particle size of the dried gelatin granules, graded on the ASTM E11 sieve series. Finer mesh dissolves faster but can clump if it isn't dispersed properly; coarser mesh is more forgiving in industrial mixers but slower to hydrate. The right answer is set by your equipment and process, not by a default - which is why mesh is specified per contract rather than assumed.
Origin
Bovine, porcine, or fish (piscine) - each carries distinct functional and regulatory implications. Halal markets require bovine or fish from certified suppliers; porcine is often cheaper but excluded from many export markets; fish gelatin is the niche specialist. Origin is also where country, species, and veterinary certification live - or don't. "Bovine" alone is not an origin. Magnus InterGlobe distributes a single-origin, single-species product: bovine skin gelatin from free-range, grass-fed Ugandan cattle, with veterinary, country-of-origin, BSE-free, and Halal documentation on every shipment.
Viscosity
Viscosity describes how the dissolved gelatin flows, measured on a 6.67% solution at 60°C in mPa·s. It is critical in capsule manufacturing, where the ribbon must form cleanly, and it is often overlooked in confectionery - where it still affects fill speed, set time, and final texture. Two gelatins at the same bloom can run very differently if their viscosity diverges.
pH & ash
These are the process indicators. pH points to the extraction route (acid vs alkaline); ash reflects how cleanly the mineral content was removed. Out-of-spec pH or elevated ash can signal sourcing shortcuts long before they show up in performance. Reputable suppliers publish both on the CoA - and a supplier who can't tell you their pH and ash, lot to lot, is telling you something else.
The vocabulary, applied to a real catalog.
Magnus InterGlobe distributes a deliberately short, single-origin range - so every term above resolves to a specific, stocked grade rather than an abstraction. The table below is where bloom, mesh, and origin stop being theory and become a purchase order.
| Grade | Bloom | Mesh | Typical use |
|---|---|---|---|
| 220 Bloom · 6 Mesh | 210–230 g | 6 (coarse) | High-volume confectionery base stock, meat and bakery |
| 250 Bloom · 20 Mesh | 240–260 g | 20 (standard) | Gummies, marshmallow, panna cotta, mousse, yogurt body |
| 250 Bloom · 40 Mesh | 240–260 g | 40 (fine) | Premium gummy texture, fast cold-water dispersion, clear jelly |
Origin across all grades: bovine skin, single-country (Uganda), single-species. Tested to GB 6783-2013 and US 2127:2019; final values confirmed batch-by-batch on the CoA. See full stocked grades & specs.
Treat gummies as a category of one.
Why demand is climbing →-
01
Bloom is a spec, not a tier. Match it to the chewiness or set you need, not to a price ladder. A softer 220 and a firmer 250 are different tools, not better and worse.
-
02
Origin is a document, not an adjective. Insist on species, country, and veterinary certification - the same trail that supports Halal and BSE-free claims.

03
Pilot before you scale. Gelatin that performs in confectionery can fail in a nutraceutical gummy where active ingredients interact with the protein matrix. The numbers narrow the field; a pilot confirms the choice.
