There is growing interest in centralized preparation of retail-ready meat cuts for distribution to widely dispersed retail stores due to the convenience of having high-quality ready-to-go products that are consistently provided to consumers at lower cost. Various centralized packaging techniques are described. Of all packaging techniques, master packaging is the most economical and shows promise for commercial application. Nevertheless, the master-packaging technique must be integrated with strict temperature control in a narrow range just above freezing (- 1.5 +/- 0.5 degrees C), good processing hygiene, and maintenance of a completely anoxic atmosphere in the package headspace throughout the distribution period to maximize storage life. Packaging using the CAPTECH process reduces the residual O2 present in the headspace to 300 ppm. Oxygen scavengers must be incorporated in the package to absorb the residual O2 and preserve the metmyoglobin reducing activity of meat tissues. Integration of all these technologies can provide a storage life of retail-ready meat up to 10 weeks in the master package followed by 3 days of retail display life. This extension of storage life is sufficient for transporting meat to distant markets.
由于能够以较低成本持续为消费者提供高质量的即食产品,将零售即用型肉类切块进行集中制备并配送至广泛分布的零售店的做法越来越受到关注。文中描述了各种集中包装技术。在所有包装技术中,主包装最为经济,且具有商业应用前景。然而,主包装技术必须与严格的温度控制(在略高于冰点的狭窄范围内,即-1.5 +/- 0.5摄氏度)、良好的加工卫生条件以及在整个配送期间保持包装顶部空间完全无氧的气氛相结合,以最大限度地延长储存期。采用CAPTECH工艺进行包装可将顶部空间中残留的氧气减少至300 ppm。必须在包装中加入氧气清除剂,以吸收残留的氧气,并保持肉组织的高铁肌红蛋白还原活性。整合所有这些技术可使零售即用型肉类在主包装中的储存期长达10周,随后还有3天的零售展示期。这种储存期的延长足以将肉类运往遥远的市场。
