Select Committee on GRAS Substances (SCOGS) Opinion: Calcium oxide

The GRAS Substances (SCOGS) Database allows access to opinions and conclusions from 115 SCOGS reports published between 1972-1980 on the safety of over 370 Generally Recognized As Safe (GRAS) food substances. The GRAS ingredient reviews were conducted by the Select Committee in response to a 1969 White House directive by President Richard M. Nixon.

Calcium oxide

  • SCOGS-Report Number: 72*
  • Type Of Conclusion: 1
  • ID Code: 1305-78-8
  • Year: 1975
  • 21 CFR Section: 184.1210

SCOGS Opinion:

Calcium oxide and calcium hydroxide as used in foods contribute to the total biologically available dietary calcium. No evidence has been found that demonstrates these compounds have adverse nutritional implications in the overall dietary intake of cations. Thus, normal physiological mechanisms that control calcium metabolism allow man to utilize these sources of calcium. In light of these considerations, the Select Committee concludes that: There is no evidence in the available information on calcium oxide and calcium hydroxide that demonstrates or suggests reasonable grounds to suspect a hazard to the public when they are used as direct or indirect food ingredients at levels that are now current or that might reasonably be expected in the future.
