Polysaccharide prediction in Ganoderma lucidum fruiting body by hyperspectral imaging.

ABSTRACT: Ganoderma lucidum is a traditional Chinese healthy food with many kinds of nutritious activities, and polysaccharide is one of its main active components. Ganoderma lucidum polysaccharide plays a vital role in improving human immunity and anti-oxidation. At present, the methods of detecting polysaccharide content of Ganoderma lucidum are destructive, and the steps are complicated and time-consuming. This study aims to explore the possibility of using hyperspectral imaging (HSI) to predict polysaccharide content in a nondestructive way during the growth of Ganoderma lucidum. The partial least square regression (PLSR) model shows good performance for Ganoderma lucidum ( Rp2  = 0.924, RPDp  = 3.622) with pretreatment method of Savitzky-Golay (SG) and standard normal variate (SNV), and feature
