FSTest Alum Detection Kit for Food & Edible Bird's Nest
Semi-Quantitative Detection of Harmful Alum Additives in Food Products
Alum (Aluminum-based additive) is toxic to the human body and is prohibited in many food categories, including edible bird’s nest.  Long-term accumulation of aluminum can damage brain cells, leading to early-onset dementia, cognitive decline, and nervous system damage.  In food safety regulations—especially in China—alum is banned from bird’s nest products, and nitrites are strictly limited to no more than 30 mg/kg.

The FSTest Alum Detection Kit provides a fast, reliable, and semi-quantitative method to detect alum residues in food, supporting quality control, customs inspections, and safety compliance in processed foods, noodles, snacks, and bird’s nests.
