Embodiment 1
[0036] This embodiment provides a method for industrialized co-production of phycocyanin, spirulina polysaccharide and protein feed using fresh spirulina, comprising the following steps:
[0037] (1) Take the washed fresh spirulina algae mud and put it into the ultrasonic extraction tank according to the ratio of algae mud:purified water (W / W 1:5). Purified water is cooled to keep the temperature of the mixture below 15 degrees Celsius.
[0038] (2) Add zirconia according to the ratio of algae mud: grinding beads (W / W 1:1), stir evenly with the algae mud mixture, and use 50K Hz ultrasonic frequency to break the wall and extract for 60 minutes. The use of grinding beads can produce cavitation effect in the ultrasonic process, which can greatly improve the wall breaking rate, increase the dissolution of phycocyanin, and the extraction rate is not lower than the freeze-thaw method and buffer soaking method, so that the ultrasonic extraction method can be applied In the industria...
