In the food processing industry, texture analyzer technology has become a vital tool for ensuring quality and consistency. One of the common challenges faced by producers of ready-to-eat products like potato salad is potato softness grading. Subjective sensory testing often leads to inconsistencies, making it difficult to maintain standard quality across batches. Cell Instruments Co., Ltd. offers an objective solution through automated bulk sample texture test procedures using advanced texture analysis systems.
A large-scale potato salad manufacturer faced repeated quality complaints due to varying textures of diced potatoes in their final products. Traditional testing methods depended on human perception, which proved unreliable. The company needed a repeatable, quantifiable solution to classify potatoes as “soft,” “ideal,” or “hard” based on measurable data.
Using the TEX-01 texture analyzer from Cell Instruments Co., Ltd., equipped with a high-capacity 2500N load cell and a custom cylinder compression-shear fixture, the processor was able to measure firmness across different potato samples.
Each diced potato sample was standardized to 300 grams and placed in the compression cell. The testing protocol used controlled displacement (85mm penetration at 750 mm/min). By measuring the maximum force exerted during the compression, a quantifiable range was established:
· Soft: below 1000N
· Ideal: between 1000N and 1500N
· Hard: above 1500N
These metrics were used to create an automated PASS/FAIL threshold to guide production.
Implementing bulk sample texture test methods offers several advantages:
· Repeatability: Standardized test setup eliminates human bias.
· Speed: Rapid testing of multiple batches reduces inspection time.
· Accuracy: Provides consistent feedback with quantifiable firmness levels.
· Automation: PASS/FAIL classification enables streamlined quality control.
The texture measurement for diced potatoes was no longer subjective, allowing real-time batch monitoring and corrections.
While the case study focuses on potato softness grading, the technology is versatile. The same setup can be used for testing textures in fruits, vegetables, pasta, legumes, and processed snacks, making the system a key asset for food R&D and QA teams.
Cell Instruments provides advanced texture analysis solutions tailored for the food industry. The TEX-01 texture analyzer is built for high-precision applications, offering customizable fixtures and software integration for a wide range of products.
With extensive experience in food packaging, pharmaceuticals, and material testing, Cell Instruments helps companies improve quality, ensure compliance, and streamline operations through accurate and efficient test systems.
Switching from subjective testing to an automated texture analyzer setup transformed the potato processing company’s quality control process. Reliable, repeatable texture measurement for diced potatoes allowed them to define acceptable product ranges and maintain customer satisfaction consistently. For processors looking to improve texture evaluation, adopting bulk sample texture test methods with Cell Instruments's TEX-01 is a proven solution.
