Introduction

In the food manufacturing industry, ensuring tortilla durability while maintaining flexibility is crucial. A tortilla should be soft enough to roll yet strong enough to hold fillings without tearing. To achieve this balance, a texture analyzer provides an objective method for evaluating tear resistance dan extensibility, replacing unreliable subjective assessments.

Testing Method for Tortilla Tear Strength

1. Sample Preparation

To conduct the test, tortillas are cut into uniform samples. Typically, six square samples are taken from each tortilla to maintain consistency.

2. Testing Process

• A tortilla sample is secured using an extensibility fixture.
• A cylindrical probe applies force at a fixed speed.
• The probe penetrates the sample to a depth of 35mm, simulating the pressure of handling and filling.
• Alternative probes, such as spherical ones, can be used to replicate real-life tearing conditions, enhancing test accuracy.

3. Analysis of Results

• Peak force measurement: Indicates the ultimate burst strength.
• Displacement at peak force: Reflects the tortilla’s extensibility.
• Work under the curve: Provides additional insights into the sample’s texture profile.

Significance of Texture Analysis in Tortilla Manufacturing

Using a texture analyzer, manufacturers can obtain real numerical data to improve product consistency. The test facilitates:

• Objective measurement of tear resistance and softness.
• Software-controlled analysis for repeatable, accurate results.
• Assessment of fresh and stale samples to optimize packaging and shelf-life.

Kesimpulan

Integrating a texture analyzer into tortilla production ensures consistency, quality, and customer satisfaction. By evaluating tear resistance dan extensibility, manufacturers can fine-tune recipes and processes to deliver high-quality products that meet market demands.
