Translucent Beverages Color Measurement

Liquid refreshments, or ‘beverages’, consist of a broad group of consumable liquids – ranging from carbonated soft drinks, fruit/vegetable juices, and milk to coffee, tea, and hot chocolate, as well as, spirits. Beverages form a key part of the culture of human society, and major brand owners know the importance that color appeal and color consistency play in a consumer’s decision to purchase. That’s why many of the world’s leaders in beverage production, like Coca-Cola, PepsiCo, Unilever, and Lipton, to name a few, rely on HunterLab’s 60+ years of experience and knowledge in providing color measurement solutions to the beverage market.

Translucent beverages may benefit from either transmittance or reflectance measurement modes, depending on the thickness of the light path selected:

– If at the path length that your customer will view the sample, you can see slight details of your thumb or finger through the liquid, the transmittance is the preferred measurement method.
– If you cannot see slight details, then reflectance measurement using directional 45°/0° is preferred, though it is also possible to use diffuse d/8° sphere geometry.

Path length is defined as the thickness of the sample from where the light enters to where it exits the sample. A simple test to determine the translucency is to pour the liquid into a clear container that simulates the thickness that the sample will normally be viewed, and hold your thumb on the back of the container and look through the sample.
