Glucono-δ-lactone Powder from Canada

Pure glucono-δ-lactone (GDL) is a heterocyclic lactone derived from gluconic acid, used primarily as a slow-release acidulant in food processing. It falls under HTS 2932.20.50.20 as it is specifically named 'other lactones - glucono-δ-lactone' within the heterocyclic compounds with oxygen hetero-atoms. This white, odorless powder hydrolyzes gradually to gluconic acid, making it ideal for applications requiring controlled pH adjustment.

Import Tips

Verify purity certificate (min. 99%) as food-grade GDL requires compliance with FDA specifications under 21 CFR

Include Certificate of Analysis (CoA) showing absence of heavy metals; common pitfall is mislabeling as general acidulant

For food use, ensure Kosher/Halal certification if targeting specialty markets to avoid customs holds
