Guida alla selezione dello strumento di prova del colore alimentare/farmaceutico

Most consumers don't realize how much thought and planning goes into the use of color in food and pharmaceutical products. When grabbing any product including juice, tablets, and syrups, consumers notice the color first. A color can convey the idea of freshness, quality, and safety. A product may be considered suspicious and questioned if it appears off in any way. This is why color measurement is especially important in food and pharmaceutical industries.

Liquid, powder, gel, and tablet are the four forms of drug and food products. Each of these forms interacts with light in a variety of ways. As an example, tablets require surface reflection evaluation, while liquids require transmission sample evaluation. Because of this, manual inspection in food and drug manufacturing processes is not consistent and does not yield reliable results.

This is why color measurement tools such as colorimeters and spectrophotometers are very useful. The systems Delta E (ΔE) and CIE Lab are used by these instruments to assign a numerical value to a color. This aids in manufacturing because color standards can be met with precision, less guesswork, and it can be determined if the color of a sample is appropriate. It also ensures every product from every batch is of the same quality.

Color management systems simplify production processes. They save reference values and establish limits for tolerances. This allows manufacturers to make adjustments and do comparisons more quickly. This minimizes human error, enhances consistency, and maintains adherence to the rigorous regulations of the industry.

The Importance of the Correct Color Testing Instrument

Color testing instruments go beyond measurement. They influence product quality, regulations, and consumer confidence. In the pharmaceutical and food industry, color fallout can be detrimental. Color variation can result in batches being rejected and color regulations being violated.

For beverages, capsules, and syrups, consistency is of the utmost importance. The same color must be present in all batches. A dependable device will ensure that color differences do not exceed the threshold.

Safety is a concern. Testing instruments must be of the best quality to ensure the requirements for control and color safety regulations are achieved. This will save the company from incurring any more control than preventive costs.

Testing tools must be of a quality that permits simple measurement. This will provide quick feedback to the production team to improve the testing system, reducing waste and increasing production efficiency.

Key Aspects In Choosing Color Testing Instruments for Food and Drugs

Know Color Expectations for Your Specific Industry Before Choosing a Color Measurement Instrument

Food and drug color regulations and requirements are unique to each food and drug product category. For instance, in the beverage industry, there are regulations for the color and clarity of the beverage, while in the pharmaceutical industry, there are regulations for the color and uniformity of the coating of tablets. Regardless of the industry, inconsistent color presentation may lead to negative customer perception and loss of approval by regulatory bodies.

The color testing instrument of choice should be able to analyze a variety of sample types, including liquids and solids as well as provide color measurements using the standard color systems like the CIE Lab color system.

Industry-Specific Measurement Standards

Color measurement standards in the food and drug industry include Delta E (ΔE) standards, which specify the tolerable color variance a product can have to be accepted as a product on the market. In the drug industry, the color variance is often very restricted.

The application of a standard measurement system provides an effective way to minimize subjectivity in quality control, particularly in maintaining uniformity in a batch and across several production sites.

Line Measurement Accuracy and Control

When it comes to the food and drug industry, accuracy is extremely important. The instruments used must be able to accurately measure the true color of the sample and provide it with a very high line contrast as this will provide an indicator for the consistency of the instrument.

Instruments such as the ST-700D and the YS3060 show reliability and high accuracy in laboratory analysis and industrial production environments.

Multipurpose Measuring

Various sample forms present one of the greatest obstacles in this industry. Liquids need special tools to measure transmitted light instead of measured light.

The YS60 Series Benchtop Liquid Color Analyzers and the TS4020 Liquid Spectrophotometer are tools made to measure liquids. They accurately and consistently measure and monitor the production of chemical solutions, syrups, and beverages.

The solid samples, as in the case of tablets and powder, portable measuring devices such as the NR145, NH310, and NR60CP are efficient and effective. They achieve and allow flexible measurements on production samples.

User Friendliness and Portability

Convenience and speed are the prime factors in many production setups, and portable measuring devices make it easy to measure on the sample site and eliminate the need to transport samples.

The simplicity, compact design, and easy-operability of the measuring tools NH310, NR145, and NR60CP make them ideal for routine quality check procedures and they reduce the need for training.

Data Control and Software

To make Modern measuring tools more effective and easier to use, measuring tools are made to come with analysis and storage software. This software ensures that the color measurement is consistent and identifies the trends and problems in the color measurement over time.

The ST-700D is a good example of advanced software integration in devices. This makes their users’ jobs easier when it comes to data management and report creation. This is useful regarding compliance and documentation.

Calibration and Maintenance

Calibration is a must when it comes to precision, and a good instrument should have a simple and easy calibration routine. Likewise, it should require little maintenance. This makes sure that there is dependable and precise instrument. The instrument should also have a long enough lifespan that replacement costs from downtime are minimized.

Choosing a durable instrument minimizes costs over time and maximizes replacement instrument downtime.

Purchase Price and After Purchase Customer Service

The instrument’s costs are important, but should not be the primary concern. An instrument that charges a premium but is of high quality is worth it, as it will end up costing less in the long run due to reduced error and maintenance.

Instruments that are of high quality and cheap also should not be the focus. After purchase customer service is also important. If their is any issue with the instrument, it should be resolved quickly to minimize instrument downtime.
