The importance of physical stability in the preparation

Botanical preparations free from synthetic preservatives require careful monitoring of residual moisture and sugar density. In our Modena laboratory, each batch is tested to confirm that the honey's sugar concentration acts as a natural stabilizer, preventing unwanted fermentation in the bottle.

Why choose amber glass bottles

Visible light and ultraviolet radiation are the main causes of oxidation in phenolic compounds extracted from walnuts. Using dark glass containers shields the contents from light and prevents molecular migration, an issue that can occur with cheap plastic bottles.

• Light protection: amber glass sharply reduces exposure to critical wavelengths.
• Tamper-evident seal: the security cap ensures the container has not been opened before delivery.
• Chemical neutrality: food-grade borosilicate or soda-lime glass does not alter the preparation's pH.

Inspection before package sealing

Before a box is sealed and handed over to the carrier, every single bottle is visually inspected against a light source for any foreign particles or micro-cracks on the container neck. Only units meeting strict sealing criteria are shipped to end customers.
