Food Additive Safety (OFAS)
3-ETHYL-2,6-DIMETHYLPYRAZINE is used for FLAVORING AGENT OR ADJUVANT. More food additive safty information please view GRAS report.

EFSA's chemical Hazards Database : OpenFoodTox
This compound is found in OpenFoodTox with the name: 2-Ethyl-3,5-dimethylpyrazine

Reference point : Defined point on an experimental dose–response relationship for the critical effect. This term is synonymous to Point of departure (USA). Reference points include the lowest or no observed adverse effect level (LOAEL/NOAEL) or benchmark dose lower confidence limit (BDML), used to derive a reference value or Margin of Exposure in human and animal health risk assessment. In the ecological area, these include lethal dose (LD50), effect concentration (EC5/ECx), no (adverse) effect concentration/dose (NOEC/NOAEC/NOAED), no (adverse) effect level (NEL/NOAEL), hazard concentration (HC5/HCx) derived from a Species Sensitivity Distributions (SSD) for the ecosystem (EFSA Scientific Committee,2018).

Reference Value

Reference Value : The estimated maximum dose (on a body mass basis) or the concentration of an agent to which an individual may be exposed over a specified period without appreciable risk. Reference values are established by applying an uncertainty factor to the reference point. Examples of reference values in human health include acceptable daily intake (ADI) for food and feed additives, and pesticides, tolerable upper intake levels (UL) for vitamins and minerals, and tolerable daily intake (TDI) for contaminants and food contact materials. For acute effects and operators, the acute reference dose (ARfD) and the acceptable operator exposure level (AOEL). In animal health and the ecological area, these include safe feed concentrations and the Predicted no effect concentration (PNEC) respectively (EFSA Scientific Committee, 2018).
