Differences in Antioxidants, Polyphenols, Protein Digestibility and Nutritional Profile between Ganoderma lingzhi from Industrial Crops in Asia and Ganoderma lucidum from Cultivation and Iberian Origin

Abstract

Carpophores of Ganoderma lingzhi (GZ) from industrial crops in China were analysed and compared with carpophores of three Iberian strains of cultivated Ganoderma lucidum (GL) (Aveiro, Madrid, Palencia) previously genetically characterized. The genetic determination of all the fungi in the study coincided with the identification provided by the companies and entities that supplied the samples. Cultivation time ranged between 107 and 141 days. The analysis of total phenol content showed to be 56.8% higher for GL from Palencia than for GZ. Intraspecific variation was a maximum of 56% from GL. The content of antioxidants, both intraspecific and interspecific, was found to be strain-dependent with a maximum variation of 78.5%. The nutritional analysis shows that there are differences in dietary fiber, protein, ash and sodium content between GL and GZ. In fatty acids analysis, only trans fatty acids showed significant differences, being higher in GL. Protein profile and digestibility of GZ and GL-Madrid mushroom proteins were evaluated by digestion with simulated gastric fluid and were different. The two species were perfectly differentiated according to their protein profile. These results should be considered for nutritional and industrial applications.

Nutritional Quality and Biological Application of Mushroom Protein as a Novel Protein Alternative

“…Protein profile and digestibility of G. lingzhi (GZ) and G. lucidum (GL)-Madrid mushroom proteins in simulated gastric fluid differ significantly. GL and GZ contain some proteins that are totally or partially resistant to simulated gastric fluid [ 37 ]. Partially hydrolyzed protein components in the mushroom are fermentable by gut microbes to release branch-chain fatty acids to enhance host health [ 11 ].…”

Application of ultrasound‐assisted enzymatic extraction to enhance triterpenoid content and the biological properties of Vietnamese Ganoderma lucidum extract

“…In recent years, more and more studies on the antitumor properties of G. lucidum extracts were carried out to evaluate its potential as a therapeutic agent (Cör et al, 2018; Liang et al, 2019). Several published papers reported that ar‐tumerone, fatty acids, and triterpenoids were reported to have the ability to inhibit the processes of cell proliferation and control the cell death cycle (Fraile‐Fabero et al, 2021; Mecca et al, 2021). Triterpenoids kill cancer cells mainly by inducing apoptosis through the activation of caspases.…”

Exploring Nutrient Profiles, Phytochemical Composition, and the Antiproliferative Activity of Ganoderma lucidum and Ganoderma leucocontextum: A Comprehensive Comparative Study

“…G. lucidum is not only harnessed as a medicinal remedy but also for its broad applications across various industries, such as nutraceuticals, health supplements, and cosmetics [11]. Proximates, minerals, and a diverse array of bioactive compounds in G. lucidum have undergone extensive scrutiny and are comprehensively understood [12,13]. In recent years, Ganoderma leucocontextum, a newly discovered species from Tibet plateau and Sichuan Province in China, has garnered attention [14].…”
