Designing modified atmosphere packages (MAPs) for fresh produce requires respiration rate (RR) data. A steady-state (SS) approach is widely used but is expensive, tedious, and time-consuming. Unsteady-state (USS) methods mitigate shortcomings of the SS approach, but comparisons between the two approaches have not been done to verify the design outcomes of MAPs, especially those with microperforations. RR measurement methods for grape tomatoes and blueberries were compared. Data were then used to design microperforated MAP packages to compare predicted design specifications created from RR data with observed shelf life. Results show that the USS method provides similar magnitudes of RR and predicts similar numbers of perforations as the SS method. Observations of packages produced using 100 µm perforations, using measured respiration data, suggest that both methods underestimated what might have been deemed correct by about one microperforation. PRACTICAL APPLICATION: Designing packaging for fresh produce requires the knowledge of produce respiration. Steady-state methods are conceptually simple, but time-consuming. Unsteady-state methods are rapid. This work compares methods on design of packages.

比较稳态和非稳态呼吸速率测量方法,用于设计带有微孔的葡萄番茄和蓝莓的气调包装

为新鲜农产品设计气调包装 (MAP) 需要呼吸率 (RR) 数据。稳态 (SS) 方法被广泛使用,但昂贵、乏味且耗时。非稳态 (USS) 方法减轻了 SS 方法的缺点,但尚未对这两种方法进行比较以验证 MAP 的设计结果,尤其是那些具有微穿孔的设计结果。比较了葡萄番茄和蓝莓的 RR 测量方法。然后使用数据来设计微孔 MAP 包装,以比较从 RR 数据创建的预测设计规格与观察到的保质期。结果表明,USS 方法提供了与 SS 方法相似的 RR 量级并预测了相似的穿孔数量。使用测量的呼吸数据对使用 100 µm 穿孔生产的包装进行观察,表明这两种方法都低估了大约一个微穿孔可能被认为是正确的。实际应用:为新鲜农产品设计包装需要了解农产品呼吸。稳态方法在概念上很简单,但很耗时。非稳态方法很快。这项工作比较了包装设计的方法。
