Miron Glass Storage test with Chives
Sprayed-, white-, green- and brown glass are permeable in the visible light spectrum and don’t offer enough protection against decomposition caused by light. As an experiment, several herbs and spices were stored for 3 months in several types of glass (white, brown, violet), and were either exposed to the sun for several hours a day or kept inside.
After 2 months, the visible quality change was recorded with photographs, and the difference in smell determined in a blind test with volunteers. The illustration shows clearly that the chive samples that were exposed to the sun have bleached in brown and white glass. As photographed in this illustration, the sample stored in MIRON violet glass shows no color change. The smell of the chives stored in MIRON violet glass was also clearly stronger and fresher.
