Elimination of hydrocyanic acid
Reduce hydrocyanic acid content
The European Commission has set the maximum level of hydrocyanic acid authorized for flaxseed at 150 mg/kg.
The saturated steam pasteurization system eliminates a significant proportion of the hydrocyanic acid contained in flaxseed. It also reduces the microbial load by 5 log of salmonella. Steripure’s equipment can process quantities ranging from a few kilograms to several dozen tonnes per day.
The benefits are twofold:
- Reduced microbial load
- Total elimination of the acid present on linseed.
Pre-treatment results
Pre-treatment analyses revealed a hydrocyanic acid concentration of 164 mg/kg in the flax seeds. This level is a cause for concern, as it exceeds the food safety thresholds established by several public health organizations. Therefore, measures must be taken to ensure consumer safety.
Hydrocyanic acid before treatment:
164 mg/kg
Limit of quantification (LOQ):
5,0 mg/kg
Results after treatment
Saturated steam injection completely eliminated hydrocyanic acid, with levels below 5.0 mg/kg.
Hydrocyanic acid after treatment:
<5,0 mg/kg
Limit of quantification (LOQ):
5,0 mg/kg
