查询词典 stability region

The stability of aloin decreased with the increase of temperature and heating time. However, the absorbency of aloin did not change with time under room temperature (20℃). The aloin was sensitive to light, and the aloe juice showed a yellowish green sediment in 2 hours after exposed to sunlight. The stability of aloin declined when the pH value arose. The aloe juice was more stable under lower concentration of sodium chloride and sucrose.
