Alpha_ASTA Color Analysis of Red Pepper Powder using the Alpha UV-Vis

This application note provides a practical demonstration of red pepper color evaluation using the ASTA Method 20.1 with K LAB’s Alpha UV-Vis Spectrophotometer. The method relies on a simple acetone extraction and single-wavelength absorbance measurement at 460 nm, enabling efficient comparison of color intensity across different red pepper samples. By applying this standardized approach, the study highlights the Alpha UV-Vis’s capability to deliver reliable, consistent, and reproducible ASTA Color values. The results confirm the instrument’s suitability for routine quality control, offering a fast and cost-effective alternative to chromatographic pigment analysis.
