The impacts of emulsions based on commercial oils on the biogenic amine formation and their indices of vacuumed packed sea bass fillets were investigated. The results showed that among biogenic amines, cadaverine, putrescine, spermidine, spermine, serotonin, dopamine, and agmatine were predominant amines in sea bass fillets stored under vacuum packaging. Significant differences (P < 0.05) in biogenic amines concentrations of vacuumed packed sea bass treated with emulsions were observed. All groups contained histamine lower than 5.0 mg/100 g, regarded as the allowable limit by the U.S. Food and Drug Administration. Polyamine levels were not affected by application of emulsion. Quality index (QI) showed an increase and after 14 d of storage it decreased in all groups. The control generally seemed to higher QI value than those of treatment groups except at 14 and 18 days while soybean and corn gave lower QI among treatment groups. Only biogenic amine index correlated with sensory acceptability of vacuumed packed sea bass, indicating that this index can be used for determination of the degree of spoilage of vacuumed packed sea bass. Emulsions extended the shelf-life (approximately 2 to 4 d) of vacuumed packed sea bass fillets by inhibiting microbial growth compared to the control. PRACTICAL APPLICATION Emulsions have become popular since they are regarded as ideal carrier for the delivery of lipophilic substances due to the ease of preparation, small particle size, their enhanced bioavailability, and long term kinetic stability. They have been proven to be self-preserving antimicrobials due to bound water in their structure and thus no available water to microorganisms. Antimicrobial emulsions have potential applications in many fields because they are inexpensive, stable, and nontoxic agents.

真空 包装 鲈鱼 鱼片 乳液 对 生物 胺 形成 的 作用 及其 指标 .

研究了基于商业油的乳液对生物胺形成的影响及其真空包装鲈鱼片的指标。结果表明，在生物胺中，尸胺、腐胺、亚精胺、精胺、5-羟色胺、多巴胺和胍丁胺是真空包装下储存的鲈鱼片中的主要胺类。观察到用乳液处理的真空包装鲈鱼的生物胺浓度存在显着差异（P < 0.05）。所有组的组胺含量均低于 5.0 mg/100 g，被美国食品和药物管理局视为允许限值。多胺水平不受乳液应用的影响。所有组的质量指数（QI）均呈上升趋势，14 d 后下降。除了第 14 天和第 18 天，对照组的 QI 值似乎普遍高于处理组，而大豆和玉米在处理组中的 QI 值较低。只有生物胺指数与真空包装鲈鱼的感官接受度相关，表明该指数可用于确定真空包装鲈鱼的腐败程度。与对照相比，乳液通过抑制微生物生长延长了真空包装鲈鱼片的保质期（约 2 至 4 天）。实际应用 乳液因其易于制备、小粒径、增强的生物利用度和长期动力学稳定性而被认为是递送亲脂性物质的理想载体，因此变得流行。它们已被证明是自我保存的抗菌剂，因为它们的结构中存在结合水，因此微生物没有可用的水。抗菌乳液在许多领域都有潜在的应用，因为它们价格低廉、稳定且无毒。
