How to choose the right color spectrophotometer for juice and liquid ?

In the juice and beverage industry, color not only reflects the quality of the product, but also directly affects consumers' purchasing decisions. However, different types of juice and beverages (such as clear juice, cloudy drinks, and high-fiber drinks) require different technical solutions when measuring color. This article will introduce the differences between transmission measurement and reflection measurement in detail to help companies accurately select the appropriate color measurement method based on product characteristics.

1. Application Scenarios of Transmission Measurement

The transmission measurement method uses the transmittance of light through a liquid sample to measure color. It is mainly applicable to:

  • Clear or translucent beverages:
    • Apple Juice
    • Grape Juice
    • lemon juice
    • Clear soft drinks

Transmission measurement is very suitable for beverages with high light transmittance, such as apple juice, and can accurately reflect the true color

Advantages:

  • Can sensitively capture subtle color differences in clarified liquids;
  • It is very suitable for beverages with high light transmittance and accurately reflects the true color.

Recommended Measuring Equipment:

  • ZHIYI-612 Benchtop spectrophotometer

Desktop spectrophotometer has dual functions of transmission measurement and reflection measurement. It adopts the internationally widely applicable D/8 lighting observation conditions and SCI/SCE (including mirror reflection/excluding mirror reflection) synthesis technology, supports SCI+SCE simultaneous rapid measurement , perfectly meets the measurement needs of milkshakes and turbid juices, and can also measure more liquid samples . TS8560 supports two lighting methods: pulsed xenon lamp and LED. The repeatability of the reflectance color value of TS8560 desktop spectrophotometer ΔE*ab ≤0.01, the inter-unit difference ΔE*ab is controlled within 0.1, and the data is stable and reliable. It complies with CIE No.15, ISO7724/1, ASTM E1164, DIN5033 Teil7, JIS Z8722 Condition C and other standards .
