摘要: 以中等规格的鲜活罗非鱼为原料,主要研究了特色风味罗非鱼的腌制、调味、真空包装和杀菌等加工技术,制成软包装罐头。通过实验,确定了盐水浸渍法的最适盐浓度为8%,腌渍时间为15min;热风干燥的最佳条件为125℃、2h,经干燥脱水后,其水分含量为52.02%;杀菌的最佳条件为125℃、15min。研制出的产品肉质致密,口感细腻,骨酥性理想,特色风味突出,食用方便,可常温下流通销售,保质期为90d,为罗非鱼的开发利用开辟了新途径。Abstract: Fresh medium size tilapia meat was adopted as raw materials, the technics of marinating, seasoning, vacuum packaging and sterilization processing for characteristic flavor of tilapia soft can was studied. The optimum conditions of processes were fixed as follows:the salt concentration was 8%, processing time was 15min in the marinating. Before the moisture content was 52. 02%, the heated-air drying was executed at 125℃, 2h, the sterilization was 125℃, 15min. Meats in the soft can were of suitable hardness, bone crisp and characteristic flavor. Meanwhile, it was convenient for eating, could distribution and sales at room temperature, and the shelf life was 90 days. This simple method for producing tilapia soft can could offer a new pathway for utilization of tilapia.
