Abstract: Objective: Researches on Gracilaria lemaneiformis-based seasoned instant marine vegetables processing methods were performed. Method: Utilizing the microagae Gracilaria lemaneiformis (Rhodophta) as the raw material, focused on the application of licorice solution and ozonized water to remove the off-flavour; acetic acid to soften the microagae; ZnCl2 to protect the decoloration; CaCl2 to guarantee the crispness; multi-seasoning to develop four products with different flavours under modified atmosphere storage whereas the shelf-life of the developed products predicted by kinetic model. Result: The optimum off-flavour removing conditions were: 4% licorice solution, sinking period 15 min, 0.2 mg/L ozonized water and treatment time 15 min. The shelf-life of the products reached to 7 months under the optimical modified atmosphere storage condition, i.e. CO2:O2:N2=6:1:3. Conclusion: Quality attruibutes of the developed products met the national food quality standard with excellent quality, which providied reference information regarding to the Gracilaria Lemaneiformis seasoned instant food processing industry.
