1. Properties: white crystalline powder, odorless, strong sweet. The sweet taste is similar to sucrose, the sweetness is 150-200 times that of sucrose, and the sweetness threshold is 0.001%-0.007%. Soluble in water, the solubility at 25 ° C is 10.20%. The solubility in methanol and ethanol was 3.72% and 0.26%, respectively. It is easily hydrolyzed in an aqueous solution. It decomposes into a monomeric amino acid under acidic conditions, and can be cyclized to a diketopiperazine when it is neutral or alkaline. The temperature increases and the reaction rate increases. The pH of the 0.8% solution is about 4.5 to 6.0.
