摘要: 目的:研究龙须菜调味即食海洋蔬菜的加工工艺。方法:以龙须菜为原料,分别采用甘草浓缩汁和臭氧水浸泡法去腥、醋酸软化、ZnCl2护色、CaCl2保脆等方法处理海藻,再经复合调味、杀菌、气调包装并运用一级动力学模型预测产品的货架期。结果:去腥最优工艺条件为甘草浓缩汁质量分数4%、浸泡15min、臭氧水质量浓度0.2mg/L、浸泡15min;研究出4种口味的复合调味龙须菜即食产品;最佳常温气调包装的复合气体组成为CO2:O2:N2=6:1:3;常温下,调味即食龙须菜产品的货架期为7个月。结论:研究的4种龙须菜即食产品各项品质指标良好,符合国家相关海藻即食食品标准规定。

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.
