<i>Lactobacillus plantarum</i> SK15 as a Starter Culture for Prevention of Biogenic Amine Accumulation in Fermented Beverage Containing <i>Hericium erinaceus</i> Mushroom

Abstract

The effectiveness of Lactobacillus plantarum SK15 starter culture in preventing biogenic amine production, such as putrescine (PUT) and spermidine (SPD), during the fermented mushroom beverage (FMB) process using Hericium erinaceus was examined. Spontaneously fermented and starter-mediated FMB was manufactured in parallel. Besides changes in pH, total acidity content, alcohol content, amino acid content, reducing sugar content, total phenolic content, antioxidant activity, and the microbial load were examined at several sampling points during the 720-h fermentation process. As a result, the L. plantarum SK15 starter prevented biogenic amine accumulation during FMB fermentation. Moreover, starter-mediated FMB can control pH and alcohol content at an acceptable level. In addition, FMB with L. plantarum SK15 had a higher level of total phenolic content (TPC) and antioxidant activity.
