Ghee packaging: jars, tins and pouches, and what keeps ghee from going rancid

Many of us remember the kalaiwala who came round to coat brass and copper vessels with a thin layer of tin. That coating had a real job. Bare copper speeds up the spoiling of fats, and the FSSAI Packaging Regulations, 2018 (compendium version IV, 9 September 2022) still say that a copper or brass container that is not properly tinned makes food unfit.

Ghee packaging is that old wisdom of our kitchens, done at scale.

The short answer is this. Ghee goes rancid when oxygen reaches the fat, and light, heat, moisture and traces of metal make it happen faster. So a good ghee pack keeps out air and light, holds very little air inside, and is filled and stored at the right temperature. In my view, lacquered tins still do this best for bulk. For retail, PET and HDPE jars, glass in a carton, lined cartons and barrier pouches all work, if you match the pack to the shelf life you print.

One honest limit before we go on.

At Jagannath Polymers we make film. We do not make tins, jars or glass. So the pouch part of this guide is closest to our own work, and for rigid packs I have relied on the official and institutional sources linked below.

Why does ghee go rancid?

Let us start with the chemistry, because every packaging choice follows from it. Ghee is almost pure milk fat. The ICPE note on packaging of milk and dairy products (undated) puts its moisture below 0.5%, so microbes are rarely the problem.

The problem is chemistry.

Oxygen slowly reacts with the fat and creates the stale, sharp smell we call rancid.

NIFTEM's training slides on packaging of ghee (NIFTEM, PMFME scheme, uploaded August 2022) list what decides how long ghee keeps:

1. Storage temperature. Warmer storage means faster spoiling.
2. Moisture in the ghee at the start. Less is better.
3. Acidity at the start. Less is better.
4. Contact with metals. Iron and copper act as catalysts for oxidation.
5. Light and sunlight.
6. Air in the headspace. The more air left in the pack, the lower the keeping quality.

The packaging team controls three of these: metal contact, light and headspace. Storage temperature belongs to your distributors. Moisture and acidity are decided in the kettle, and no pack can rescue ghee that left the kettle with too much of either. I would start any ghee packaging project by reading that list with the production head.

Tins, jars, glass, cartons and pouches compared

I have put this table together from what NIFTEM's slides and two CFTRI chapters in ICPE's book Plastics in Food Packaging (undated) say about each pack:

Let us look at a few of these in more detail:

1. Tins. The CFTRI chapter on milk products says ghee was traditionally packed in tinplate for long storage. The ICPE note adds that tins are filled to the brim with no air gap and give a shelf life of over one year. NIFTEM insists on properly lacquered tins. The FSSAI Packaging Regulations list tinplate to IS 1993 in Schedule II, and regulation 3(7) bans reusing tin containers for food.
2. HDPE versus PET. The CFTRI chapter on oils, fats and vanaspati says HDPE is inferior to PET in oxygen barrier, but the thicker walls of HDPE containers allow its use.
3. Pouches. The CFTRI milk products chapter reports storage studies in which polyethylene alone was not suitable for long storage of ghee. Co-extruded films based on polyamide (nylon) and laminates based on PET were good economical choices for more than 120 days at 27°C.

For pouch film, FSSAI's Schedule III also lists IS 14636, the Indian standard for flexible packaging materials for edible oils, ghee and vanaspati. Ask your pouch supplier which standard their material is tested against. If you want to understand barrier numbers on a film data sheet, read our guide to OTR and WVTR in plain words.

Air in the pack: fill it high, and think about the second spoon

Headspace is the air left between the ghee and the lid. Less headspace means less oxygen sealed in with the ghee. This is why tins are filled to the brim.

There is a second point that is easy to miss. The CFTRI oils chapter notes that in a bag-in-box, the air space does not grow as oil is taken out, unlike in bottles and jars. A jar works the other way. Every spoon we take out at home leaves more air in the jar.

So a 1 kg jar that a small family takes three months to finish spends weeks with a lot of air behind the lid. I would rather see two smaller jars in that home than one big one. Pack size is a shelf life decision as much as a price decision.

Filling warm ghee without damaging the pack

Ghee is filled warm, while it is still liquid. That is good for filling and hard on some packs. These are the checks I would make before a new pack goes on the line:

1. Measure the ghee temperature at the filling nozzle, not at the kettle.
2. Ask the jar or pouch maker for the highest filling temperature their pack is rated for, and stay well below it. Ordinary PET jars soften when they get too hot.
3. For pouches, keep ghee off the seal area. Fat in the seal weakens it.
4. Do not stack warm jars high until you have tested that the bottom jar keeps its shape.

Leaks: summer finds the weak cap

In our Indian summer, ghee on a truck or a shop shelf can turn completely liquid. A cap that holds solid ghee in December may not hold liquid ghee in May.

The CFTRI oils chapter describes screw caps with foil, PVC or expanded polyethylene liners on plastic oil bottles. Whatever closure you use, I would test it the hard way:

1. Fill a few jars, close them as the line does, and warm them until the ghee is fully liquid.
2. Keep them upside down on blotting paper for a day.
3. Look for any stain at the cap. One stain is one complaint waiting to happen.

For tins, inspect the seams and the lid. For pouches, run the same squeeze test with liquid ghee and check the seals.

Storage: not too warm, and not in the fridge

NIFTEM's slides recommend storing ghee at 21°C, and say it can keep up to 12 months at that temperature. They also warn that refrigerated storage gives ghee a greasy and pasty texture, and that oxidised flavour develops faster at higher temperatures.

So our advice to your distributors would be plain. Keep cartons out of direct sun, away from warm walls and away from shop windows.

Label basics for packed ghee

The label rules we all follow are in the FSSAI Labelling and Display Regulations, 2020 (compendium version VIII, 9 September 2025). For a pack of ghee, the basics are:

1. The name of the food. FSSAI's dairy standard gives "Ghee" as the name for this product.
2. The green vegetarian symbol. Milk and milk products are left out of the definition of non-vegetarian food.
3. The FSSAI logo and the licence number of the brand owner, plus the manufacturer's or packer's licence number if different.
4. A lot or batch number.
5. The date of manufacture or packing, and the "Expiry" or "Use by" date, grouped together. "Best before" may be added. For a shelf life over three months, the month and year are enough, though the full date is also allowed.
6. Storage conditions, wherever the date depends on them.
7. Nutritional information, plus net quantity, retail sale price and consumer care details as the Legal Metrology Act, 2009 and its rules require.
8. Ghee sold for diya or pooja, not for eating, must carry a black cross inside a square, as regulation 5(15) requires.

Label rules change, and what we have given here is a summary, not legal advice. Confirm your final artwork with a food safety consultant before you print.

A storage trial before you change packs

Before you move from tins to jars, or from jars to pouches, I would run a simple trial. Pack the same batch of ghee in the old pack and the new one. Keep some of each at room temperature in light, some in the dark, and a few in a warm place. Smell and taste them every month against the old pack. If you want numbers as well, we would ask a food lab to measure how far oxidation has gone.

If you are planning ghee pouches, send us your pack size and the shelf life you want to print. We will suggest a film structure you can put into that trial.
