Comprehensive Packaging Testing Methods and Instrument for Sponge Cake Shelf Life

Product catalog summary

Introduction
Packaging is vital for maintaining the quality of perishable goods like sponge cake. Issues such as mildew and bag deflation necessitate comprehensive testing to identify causes.

Testing Methods
Labthink's packaging test center conducted several tests to evaluate packaging materials:

Barrier Properties: Oxygen and nitrogen transmission rates (OTR and NTR) were measured. High values indicated poor barrier performance, leading to oxidation and product deterioration.
Structural Integrity: Heat-seal strength and leak tests were performed. Low heat-seal strength and leakage can result in contamination and spoilage.
Headspace Air Analysis: Assessed gas composition changes over time. A decrease in nitrogen and increase in oxygen can accelerate degradation.

Instruments Used
The analysis utilized several instruments:

Oxygen and Nitrogen Transmission Rate Tester: Measures gas transmission rates.
Heat Seal Strength Tester: Evaluates seal strength.
Leak Tester: Detects packaging leaks.
Headspace Gas Analyzer: Analyzes gas composition within the package.

Specific Instruments
Labthink offers specialized instruments for these tests:

Labthink C406H: Tests oxygen and water vapor transmission rates.
Labthink C630H: Determines optimal heat sealing parameters.
Labthink C660M: Measures seal strength and integrity.
Labthink C650M: Portable gas analyzer for oxygen and carbon dioxide.

Findings and Recommendations
The tests revealed poor barrier properties and inadequate heat-seal strength, leading to leakage and spoilage. Understanding these failures allows for corrective actions to improve quality and shelf life.

Conclusion
As demand for functional packaging grows, testing methods evolve for comprehensive evaluation. Labthink encourages industry collaboration for quality control. Visit www.labthink.com for more information.

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

Labthink Instruments Co., Ltd. [email protected] +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. [email protected] +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 seals....
