Topic- Analytical Methods of Carotenoids in Food. A Review

1.  Introduction

Carotenoids are natural plant pigments widely distributed in many foods and food products that produced by plants and microorganisms. Carotenoids play a crucial protective health benefits role in human health (1). The review’s main objective is to present several analytical methods that used to detect Carotenoid extracts in the past ten years. Besides, to examine the performances, applications, and recent advancements in the chromatography (OCC), thin-layer chromatography (TLC), and high-performance thin-layer chromatography (HPTLC) and Colorimetry techniques.
