Abstract:The kelp which is a kind of large marine brown algal plant with more nutritious was chosen as experimental raw materials to product instant kelp powder.The experiment procedure included a series of crafts，such as enzymatic hydrolysis，curing，nursing of color and ripening etc.The author mainly discussed the curing process of calcium chloride system while the kelp was enzymatically hydrolyzed.The effects on the formation of kelp powder were influenced by different concentration，different time and different temperature.It showed by experimental results that when the kelp was solidified for 60 s in the 2%calcium chloride solution of 25℃，then cleaned it up，put it into the 0.2%calcium chloride solution of 25℃ to solidify for 20 min，the resulting gel was the best，which could reach maximum of tensile strength and elasticity.
