Korma or churi: the first decision

Guar seed processing yields three streams. The endosperm becomes splits and then gum. What remains divides into two fractions with quite different feed value.

Much of the material traded internationally is a blend of the two fractions sold against a protein guarantee, so the words korma and churi on their own do not tell you what is in the bag. Specify the protein guarantee, whether you want pure korma, pure churi or a defined blend, and hold the supplier to a consistency tolerance across lots — a feed formulator can work with a lower protein, but not with a moving one.

State the protein basis

A 50 percent protein figure on a dry matter basis is roughly 45 percent as-is at 10 percent moisture. Contracts that state a guarantee without stating the basis produce a dispute that only surfaces after arrival analysis. Specify as-is or dry matter alongside the number, and specify the analytical method.

Residual gum: the parameter that decides performance

This is the section that matters most, and it is routinely left out of guar meal specifications that stop at crude protein.

Guar gum is extracted from the endosperm, but residual galactomannan remains in the meal. Galactomannan is exactly what guar gum is sold for — it is highly viscous in solution. In the gut of a monogastric animal, that viscosity is not an asset. Raised digesta viscosity depresses feed intake and reduces nutrient digestibility, which is why guar meal has historically been limited to modest inclusion rates in poultry and fish diets.

Ruminants handle it considerably better, which is the underlying reason churi sits comfortably in cattle rations while korma for poultry and aquafeed needs more care.

Toasting is the answer, and it is a specification

Heat treatment — toasting or roasting — reduces residual gum viscosity and deactivates heat-labile antinutritional factors. That is why toasted guar meal commands a premium and why it is the grade that belongs in a broiler or aquafeed formulation.

Specify residual gum as a named parameter with a maximum, and specify whether the material is toasted, with the process described. Then do the thing most buyers skip: run a trial at your intended inclusion rate in your own species and measure performance, because the useful inclusion ceiling depends on your formulation and your animal, not on a datasheet. A supplier who asks what species and what inclusion rate you have in mind has sold into feed before.

Non-GMO by origin: a real advantage

Guar is not genetically modified in commercial cultivation. Guar meal is therefore a non-GM protein source by origin rather than by segregation — unlike non-GM soybean meal, which carries an identity preservation cost because the commodity stream is largely GM.

For European and Norwegian feed buyers who must document non-GM status, that is a structural rather than a contractual advantage. Require the non-GMO declaration as a named contract document with supporting evidence, and note that guar meal also serves as a partial substitute for soybean meal in protein terms, which is how most formulators first come to it.

Reference specification

Acid insoluble ash deserves attention. It is the sand and silica indicator, and in a by-product traded on protein it is the cheapest line on the certificate to overlook and one of the easier ways for a lot to be quietly diluted.

Why availability does not follow feed demand

This is the structural point that distinguishes guar meal from soybean meal or rapeseed meal, and it catches buyers who plan annual volumes without understanding it.

Guar meal is a by-product of gum milling. Mills run to meet guar gum demand, and a large share of that demand comes from industrial and oilfield applications rather than from food or feed. So meal availability is derived from gum output, not from feed market conditions.

The practical consequence: guar meal can tighten while your feed demand is strong, because the mills are running less gum. It can also loosen when gum demand is high. Guar is also a single rain-fed kharif crop concentrated in one region, sown with the monsoon in July and August and harvested from October, so the monsoon sits behind both. For an annual requirement, contract with a volume commitment and a price mechanism rather than assuming spot availability, and ask your supplier what gum production their meal comes off.

Origin and season

Guar is grown in the arid zones of Rajasthan, Haryana and parts of Gujarat, sown in the kharif season around July and August and harvested from October. Jodhpur in Rajasthan is the principal processing centre for the guar industry, with further capacity in Gujarat. The processing base is substantial — over 200 licensed guar gum and guar meal units across the two states.

Packing and loading

How to qualify an Indian guar meal supplier

1. State your species and intended inclusion rate first — it determines whether you need toasted korma or standard churi.
2. Ask for residual gum as a figure on a recent lot, not a general assurance.
3. Specify the protein basis and the method, and ask for lot-to-lot variability data across recent shipments.
4. Ask for acid insoluble ash, which is where dilution shows up.
5. Ask whether the counterparty operates its own gum mill or buys meal — in a by-product, that determines consistency.
6. Require the aflatoxin sampling plan in writing before the first order.
7. Run a feeding trial at your intended inclusion rate before committing to an annual programme.

Frequently asked questions

Korma or churi?

Korma is the germ fraction with higher protein, commonly around 50 percent and above, suited to poultry and aquafeed. Churi is the husk fraction, lower in protein, suited to ruminant rations. Much traded material is a blend against a protein guarantee.

Why does residual gum matter?

Residual galactomannan raises digesta viscosity in monogastrics, depressing intake and digestibility. Ruminants tolerate it better. Specify residual gum as a named maximum and specify whether the meal is toasted.

What does toasting do?

Heat treatment reduces residual gum viscosity and deactivates heat-labile antinutritional factors, which is why toasted meal is the grade for poultry and aquafeed.

Is guar meal non-GMO?

Yes — guar is not genetically modified in commercial cultivation, so it is non-GM by origin rather than by segregation. Require the declaration as a named contract document.

As-is or dry matter protein?

Specify which. 50 percent on a dry basis is roughly 45 percent as-is at 10 percent moisture.

How much loads into a container?

Around 25 to 27 MT in a 20-foot container; weight limited.

What is the HS code?

HS 2308.00 for vegetable materials used in animal feeding. Confirm the eight-digit national sub-heading with your broker.
