Calcium oxide

Report No.:  72
Type of Conclusion:  1
ID Code:  1305-78-8
Year:  1975
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.
