中文摘要: 将鲶鱼肉绞碎后加入冰点调节剂和天然保鲜液制成鲶鱼肉饼(Channel catfish patties,CCP),真空包装之后在冰 温条件下贮藏(-1.5±0.02)℃ 70 d 考察其品质变化。主成分分析表明,反映 CCP 品质变化的主要指标依次是感官评分、 微生物指标(细菌总数及嗜冷菌数)、化学指标(TBARS 值、TVB-N 值)、物理指标(蒸煮损失率、L*、W、弹性、黏着性)。将 真空包装技术、冰温贮藏技术、冰点调节剂技术和天然保鲜剂技术相结合可将 CCP 货架期从 14 d 延长至 42 d,所建立 的 CCP 冰温贮藏条件下的新鲜度品质综合评价模型,可为全面分析 CCP 的品质状况和质量评级提供参考。
Abstract:Channel catfish patties (CCP) were prepared by adding cryoprotective agents and natural preservatives to the minced catfish fillet. The vacuumed packaged surimi were stored for 70 days under CFPS (- 1.5±0.02) ℃. Principal component analysis showed that the main indices that can well reflect the CCP quality changes were sensory marks,microbiological indicators including TVC and psychrophilic count,chemical indicators including TBARS value and TVB -N value,physical indicators including cooking loss,L*,W, springiness,cohesiveness in sequence. The shelf life of CCP supplemented with cryoprotective agents and natural preservatives can be prolonged from 14 days to 42 days under CFPS. The established comprehensive freshness evaluation model provided the references for the CCP quality grading.
