In plant-based protein development, many researchers have uncovered beet powder as an essential ingredient for meat alternatives. This vibrant purple-red substance can create the signifying pink color we often associate with real meat, but it needs to be used strategically. Too much beet powder in meat alternatives may make the plant-based protein hot pink, and too little may lead to an unappetizing gray.
Create Quantitative Color Measurements With Spectrophotometry
Color is a measurable science, even if it seems like a subjective quality. We perceive color based on how much an object transmits and absorbs the wavelengths of light, and we can measure this transmittance and absorbance to quantify color.
Spectrophotometers achieve this measurement with a single light source separated into each individual wavelength. These different wavelengths appear as different colors. Violet light has the highest wavelength frequency, and red has the lowest.
A spectrophotometer will isolate a single wavelength and direct it at a sample. Then, a sensor will measure how much of the light is absorbed and transmitted. The colors an object transmits are the colors we see, so beet powder transmits violet and red. The spectrophotometer will create a dataset of the different wavelengths for users to understand the color makeup of a sample.
