Glucono Delta Lactone (GDL) Supplier in Malaysia
- Also known as
- GDL
- Gluconolactone
- Glucono-1,5-Lactone
- D-Glucono-Delta-Lactone
Glucono delta lactone supplier in Malaysia for tofu, bakery, meat processing and cosmetic formulators. The trade orders it as GDL and food technologists write it as gluconolactone or E575 (CAS 90-80-2, C6H10O6). It is the cyclic lactone of gluconic acid, a white crystalline powder that hydrolyses in water and so lowers pH gradually rather than on contact.
That delayed acidification is the reason it is specified. Silken and packaged tofu plants disperse it into cold soy milk and let the curd form in the sealed pack, bakers use it as a slow leavening acid, and fermented sausage producers use it to accelerate cure. Dairy, cheese and beverage work uses it as a mild acidulant.
Food grade E575 accounts for most demand, with cosmetic grade sold into skincare formulation as a poly hydroxy acid and chelating aid, and technical grade into industrial pH control. Particle size is worth naming, since a finer cut releases acid sooner than a coarser one.
This page covers the lactone only. Gluconic acid and sodium gluconate are separate products, and calcium sulphate and nigari are competing coagulants rather than grades of it. Send the grade, application, specification, quantity and delivery location with the enquiry.

Glucono Delta Lactone grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Food grade glucono delta lactone (E575) | white fine crystalline powder | — | Coagulant for silken and packaged tofu, where the acid is released gradually as the lactone hydrolyses and the soy milk sets smoothly inside the sealed pack. Also used for mild acidulation in dairy and beverage work. | Confirm the required pack format with the quotation. |
| Bakery and cured meat food grade | crystalline powder, coarser cut available | — | Slow-release leavening acid in chemically raised doughs and batters, and cure acceleration in fermented sausage, where the rate of acid release is tuned by particle size rather than by dosing a stronger acid. | Confirm the required pack format with the quotation. |
| Cosmetic grade gluconolactone | white fine crystalline powder | — | Poly hydroxy acid and chelating aid in skincare formulation, used where a PHA rather than an alpha hydroxy acid is written into the formula. Confirm the cosmetic specification and the documentation needed. | Confirm the required pack format with the quotation. |
| Technical grade glucono delta lactone | crystalline powder | — | Industrial pH control and metal-ion sequestration in process chemistry that needs a solid, gradually acidifying lactone rather than a free acid or a gluconate salt. Supply is subject to applicable requirements. | Confirm the required pack format with the quotation. |

Glucono Delta Lactone applications
Safety and handling
Store sealed in a cool, dry place, because the powder takes up moisture and hydrolyses once it is wet, which is the reaction the product is bought for. Keep away from strong alkalis and control dust when weighing and blending. Follow the safety information issued with the grade quoted.
Common questions about glucono delta lactone
Is glucono delta lactone the same as gluconic acid or sodium gluconate?
No. This product is the cyclic lactone, a dry crystalline powder that only forms gluconic acid after it dissolves and hydrolyses. Gluconic acid is supplied as the free acid and sodium gluconate is its sodium salt, both separate products with their own pages. Order the one your specification names by name.
Is gluconolactone the same as glucono delta lactone?
Yes, they are the same material. Gluconolactone is the shorter form a food technologist or cosmetic formulator usually writes, GDL is the acronym the trade orders under, and E575 is the additive number used on food-grade material.
Why is GDL used as a tofu coagulant?
Because it acidifies slowly. The powder disperses in cold soy milk without setting it, then releases gluconic acid on heating, so the curd forms evenly inside the sealed pack and gives the smooth body silken tofu is judged on. Dose depends on the soy solids and the texture target, so state both.
Can it replace calcium sulphate or nigari in tofu production?
The three coagulants give different texture and yield, so a change is a recipe change rather than a swap. Calcium sulphate and nigari set the curd on contact and suit block and firm styles, while the lactone suits smooth silken and packaged formats. Trial before committing a production line.
Which grade should I request?
Food grade E575 covers tofu coagulation, bakery leavening acid, cure acceleration and beverage acidulation. Cosmetic grade is asked for in skincare formulation work. Technical grade covers industrial pH control and sequestration where no food or cosmetic specification applies.
Does particle size matter?
It does when the timing of acid release matters. A finer crystalline cut dissolves and hydrolyses sooner, which suits fast bakery systems, while a coarser cut slows the acid release in cure mixes and longer processes. State the process step and the timing you need.
What details are needed for a price enquiry?
Provide the grade, application, target specification, particle size preference, quantity and delivery location. Mention pack format and any documents your goods-in process requires so the quotation covers the whole requirement.
