Frequently Asked Questions
What is GDL (Glucono Delta Lactone)?
GDL is a natural, food-grade acidifier derived from glucose. It slowly hydrolyzes in water to produce gluconic acid, gently lowering pH without a sudden shock.
Why is it called a "slow-release acidifier"?
Unlike strong acids that act instantly, GDL hydrolyzes gradually, providing a controlled pH drop. This is ideal for applications like tofu making, where even coagulation is crucial for smooth texture.
How does GDL benefit tofu production?
It acts as a coagulant that produces a fine, uniform gel, resulting in silky smooth tofu (like "silken tofu"). It also extends shelf life by its gentle acidification.
Can GDL be used in baking and meat processing?
Yes. In baking, it works with baking soda as a leavening agent. In meat products, it helps with color development, reduces nitrite usage, and improves water retention.
What are the typical specifications?
We offer food-grade GDL with purity ≥99%, conforming to FCC/E300 standards. It appears as a white crystalline powder, free-flowing and odorless.
Do you provide samples before bulk order?
Absolutely. Samples are available for quality testing; you only need to cover the shipping cost. We can also arrange door-to-door delivery for sample orders.
