Some pigments can be used as coloring agents and are allowed to be added to poultry feeds, which can make animal meat and eggs more vibrant in color. It is more common to add pigments to premixed feeds and full-price feed processing and production. If the added pigments are qualified products, and the use is not excessive, then the intake through the meat of livestock will not cause health effects on people. However, some pigments are carcinogenic to humans, so the detection of pigments added to feed is particularly important.
There are many different types of pigments with different properties, and the corresponding analytical methods are also diverse. Based on different analytical principles, Lifeasible offers a variety of rapid methods for the determination of pigments in feed. We aim to establish a method for the simultaneous and rapid determination of multiple pigments in feed. It is used for quality and safety monitoring and evaluation of feeds to guide scientific, safe, and green livestock breeding.

The methods we offer to detect
- Enzyme-linked immunosorbent assay (ELISA) method. Highly sensitive, but generally only 1 or 2 or 3 pigments can be detected at a time.
- Colorimetric method. Has a high sensitivity.
- Infrared spectroscopy. Enables rapid identification of target compounds.
- Spectrophotometer method. Simple operation and relatively low cost.
- Thin-layer chromatography (TLC). Enables the characterization of the pigment to be examined with the help of the shape of the spot, its color, Rf coefficient, and its light resistance, thus improving the accuracy of qualitative detection.
- Electrochemical detection method. Convenient, rapid, sensitive, and low-cost.
- High-performance liquid chromatography (HPLC). Easy, fast, accurate, reproducible, and able to meet your qualitative and quantitative requirements in actual testing.
- High-performance liquid chromatography-mass spectrometry (HPLC-MS). Accurate and reliable results, good recovery, and precision.
