Conclusion:
1. SiO2 is in many food products today to minimize lumping of powders. In some cases SiO2 alone will not deliver the desired flow results.
2. Nu-FLOW can be added to existing spice blends (that may or may not contain an anti-caking agent) to eliminate lumping. Further testing is being pursued in the same formulations to document the full effect of replacing synthetic anti-caking agents.
3. Optimum dose of Nu-FLOW to be added to these spice blends was 1%. Lesser rates showed benefits, but optimum addition was 1%. Depending on the working environment (humidity controlled facility), it may be possible to lower the rate of the Nu-FLOW to 0.75%.
