In food and pharmaceutical manufacturing, precision in color and fluid analysis is essential for product consistency, safety, and regulatory compliance. Portable and desktop spectrophotometers are widely used to measure color hue across various scales and calculate color differences (ΔE*), ensuring uniformity in appearance and detecting subtle variations in ingredients or packaging. These instruments also support advanced metrics such as yellowness, whiteness, and stain fading, which are critical in evaluating product degradation or contamination. BYK-Gardner’s spectro2guide and spectro2profiler models offer high-resolution color measurement with integrated gloss and texture analysis, ideal for transparent liquids and solid formulations.
To simulate real-world lighting conditions, color comparison booths equipped with illuminants like D65, D50, TL84, A, and UV are employed for visual inspections and quality assurance. For rheological testing, spindle viscometers with variable speeds—such as BYK’s byko-visc CP—are used to determine the viscosity of liquids ranging from syrups and suspensions to emulsions and gels. These viscometers offer precise shear rate control and built-in temperature regulation, enabling accurate modeling of flow behavior under manufacturing conditions. Together, these tools form a robust framework for mathematical modeling, predictive analysis, and process optimization in food and pharmaceutical production.
