EC number: 232-435-9 | CAS number: 8028-89-5 The substance obtained by controlled heat treatment of food-grade carbohydrates. Food-grade acids, alkalies, and salts may be used to assist carmelization. Food-grade antifoaming agents may be used in an amount not greater than that required to produce the intended effect. Consists essentially of colloidal aggregates that are dispersible in water but only partly dispersible in alcohol-water solutions. Depending upon the particular carmelizing agent used, may have a positive or negative colloidal charge in solution.

-at 2.2 mg/L: 62.12% yield inhibition compared to the control and 36.55% growth inhibition compared to the control.
-at 3.8 mg/L: 88.19% yield inhibition compared to the control and 69.46% growth inhibition compared to the control.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- Based on frond number, the NOErC was 100 mg test item.L-1 and both the LOErC and ErC50 were > 100 mg test item.L-1 (basis for effect: growth rate).
Based on dry weight, the NOEyC was 100 mg test item.L-1 and both the LOEyC and EyC50 were > 100 mg test item.L-1 (basis for effect: yield).
