Semi-commercial scale production of carrageenan plant growth promoter by E-beam technology

E-beam irradiation of carrageenan PGP was also studied to increase its throughput of production. Degradation of carrageenan by e-beam irradiation is inhibited by the formation of crosslinks. Optimisation by addition of hydrogen peroxide to improve degradation is discussed. A continuous flow liquid handling system has been fabricated to increase throughput of the carrageenan PGP. Using the optimized parameters, the system can produce a volume of approximately 1700 L/h.
