What are Cryogenic Spices ?
Cryogenic grinding of herbs and spices involves powdering these elements at sub-zero temperatures ranging from 0 to – 196°C. The elements are frozen with liquid nitrogen, as they are being ground. This process does not damage or alter the chemical composition of the main elements in any way. Standard grinding process which does not use a cooling system can reach up to +200°F. This high temperature can reduce volatile components and heat sensitive constituents in spices
Superiority of Cryogenic over Standard Grinding Systems
Traditional Grinding System | Cryogenic Grinding System |
---|---|
The heat is developed inside the grinding mill | Temperature below 0*c inside the grinding mill |
The heat, which is developed during grinding, leads on one hand to evaporation of the essential oil and on the other hand, heat sensitive fats are melted. | Negligible loss of volatile component |
This in turn can lead to the grinding elements become greasy (oily) and even harms the machine by blocking it. | Not in Cryogenic process |
High energy consumption | Low energy consumption |
High capacity motors are required to grind the material | Low capacity motors are required to grind the material |
Essential value of material are evaporated | No evaporation of essential value |
No control on particle size | Particle size are under controlled |
Superiority of the whole cryogenically process over standard grinding process spices w.r. t Essential Oil Content
Spices | Ungrounded essential oil content (ml. Per gm.) | % | Cryogenic Grinded essential oil content (ml. Per am.) | % | Standard Grounded essential oil content (ml. Per qm.) | % |
