K. R. BHATTACHARYA; C. M. SOWBHAGYA International Journal of Food Science & Technology 1972. doi:10.1111/j.1365-2621.1972.tb01667.x
Other claims from this paper (11)
- Method / resource A nine-point alkali reaction score was devised from successive rice kernel degradation stages.
- Observation Each rice variety was first attacked at a particular potassium hydroxide concentration.
- Observation Each variety was almost fully degraded at a potassium hydroxide concentration 0.7‐0.8% higher.
- Method / resource Nine degradation stages were distinguished from residual chalky substance, collar diameter and consistency.
- Method / resource A 1.4% KOH concentration maximized score spread among rice varieties.
- Method / resource The test could be conducted in ordinary Petri dishes at room temperature for 18–24 hr.
- Observation Rice varieties exhibited three alkali reaction types.
- Observation Type A reaction showed progressive cracking and corrosion.
- Observation Type B reaction showed progressive grilling and cottony transformation.
- Observation Type C reaction showed kernel opening, splitting and gradual dense cottony transformation at increasing KOH concentration.
- Observation Most japonicas had type C reaction.
