|
In order to improve the qualities of red ginseng extract and decrease precipitate formation in ginseng drink, red ginseng extract were hydrolyzed with α-Amylase and characteristics of the hydrolyzed ginseng extract were investigated. 1.08% of isomaltose were produced and glucose content was increased from 2.83% to 11.03% in the hydrolyzed red ginseng extract. Total ginsenoside content of the hydrolyzed ginseng extract were decreased from 1,661 mg/100g extract to 1,389 mg/100g extract. The hydrolyzed ginseng extract enhanced the growth of Lactobacillus casei, Lactobacillus rhamnosus and Lactobacillus helveticus. Bitterness and astringency of the hydrolyzed ginseng extract were lower than those of the ginseng extract Precipitate formations in ginseng drink prepared with the hydrolyzed ginseng extract were significantly reduced in the storage conditions of 40?C for 4 weeks compared to those of control.
