Comprehensive Packaging Testing Methods and Instrument for Sponge Cake Shelf Life - 1

Labthink Instruments Co., Ltd. info@labthink.com +86-531-85068566 Instrument for Sponge Cake Shelf Life Packaging plays a crucial role in maintaining product quality, particularly for perishable goods like sponge cake. When issues such as mildew and bag deflation arise, comprehensive testing is essential to identify the root cause. In this case, Labthink packaging test center employed a series of tests to evaluate the packaging material. The first set of tests focused on the material's barrier properties. Oxygen and nitrogen transmission rates (OTR and NTR) were measured to assess the package's ability to protect the product from oxidation. High OTR and NTR values indicated poor barrier performance, allowing oxygen ingress and nitrogen loss, which can accelerate product deterioration. To evaluate the package's structural integrity, heat-seal strength and leak tests were conducted. Heat-seal strength determines the package's resistance to opening, while the leak test identifies any vulnerabilities in the seals. Low heat-seal strength and package leakage can lead to product contamination and spoilage.

Labthink Instruments Co., Ltd. info@labthink.com +86-531-85068566 Finally, headspace air analysis was performed to assess the gas composition within the package over time. Changes in gas composition can affect product shelf life. A decrease in nitrogen and increase in oxygen levels, as observed in this case, can accelerate product degradation. The test instruments used in this analysis likely include:     Oxygen and Nitrogen Transmission Rate Tester: Measures the rate at which gases pass through the packaging material. Heat Seal Strength Tester: Evaluates the strength of the package's...
