Development of Aloe Fermentation Products and Improvements of Gastrointestinal Function in vitro

Three aloe fermentation products from Ganoderma lucidum (AG), Hericium erinaceum (AH), and Phellinus linteus (AP) were obtained by fermenting mushroom mycelia using aloe as a substrate. When AG, AH, and AP were added to sterilized aloe and fermented for 5 days, the color of the aloe fermentation product changed from pink to beige, which is aloe's natural color, through the fermentation time. The pH of the aloe fermentation products ranged 4.32-4.36 shortly after inoculation and then 4.62-4.68 during the 5 days of fermentation. pH increased by 7% during the total fermentation time. The solid content had increased 1.28-1.40 times. The contents of aloin A and B increased with fermentation time. β-Glucan content decreased with fermentation time. The urease inhibition activity (%) were remarkable in AG-4 96.70, AH-4 92.30, and AP-4 66.40%, indicating these products had growth inhibition effects against Helicobacter pylori. Moreover, AG and AH were most effective as anti-H pylori treatments.
