恒温微胶囊对冷鲜肉防腐保鲜的研究

摘要：微胶囊技术是微量物质包裹在聚合物薄膜中的技术，恒温微胶囊即利用其包裹物的相变释放或吸收热量的原理，使物质能够短时间内维持恒定温度，可应用于解决冷鲜肉短时间内脱离冷环境后发生的变质问题。本文通过研究恒温微胶囊单独或结合缓释肉桂精油微胶囊在冷鲜肉防腐保鲜中的作用，对比在冷鲜肉在储藏过程中的抑菌效果和品质差异，评估了微胶囊对冷鲜肉防腐保鲜的效果，主要通过感官特性，理化指标和微生物的数量，初步探究了恒温微胶囊对冷鲜肉的防腐保鲜效果。实验表明单一使用恒温微胶囊或缓释肉桂精油微胶囊对冷鲜肉的保鲜效果并不理想，而恒温微胶囊和缓释肉桂精油微胶囊结合使用对冷鲜肉保鲜效果明显，但短时间内效果不显著，时间越长，其保鲜效果越明显。42756

Study on preservation of thermostatic micro capsule to the cold fresh meat

Abstract: Micro capsule technology is a technology that trace substance is wrapped in polymer film. The technology of thermostatic micro capsule enables the material to be insulated for a short time using the principle of phase change releases or absorbs heat of the packages, can be applied to solve the problem of cold meat spoilage in a short period of time out of the cold environment. This paper assesses the effect of micro capsule on preservation of chilled meat through study of the effect of thermostatic micro capsule alone or in combination with slow-release cinnamon essential oil microcapsule in chilled meat preservation，and contrasting their antimicrobial effect and quality difference In chilled meat, and preliminarily explores the preservation effect of thermostatic micro capsule to chilled meat mainly through the sensory characteristics, physical and chemical indicators and the number of microorganisms. Experiments showed that the preservation effect of single use thermostatic micro capsule on cold meat was not ideal, and combined the use of thermostatic micro capsule and slow release cinnamon essential oil microcapsule has an obvious effect, but the effect was not significant in short time, the longer the time, the more significant effect.
