オリゴ乳酸ラック製造の様子

L-type fermented Lactic acid extracted from natural sucrose as a raw material.

Natural sucrose （sugar beet, etc.）→L-type fermented lactic acid →heat treated/freeze dried →condensed/smashed →Oligo Lactic Acid [LAC]
Oligo Lactic Acid [LAC] has stable quality

Unlike agaricus and propolis, quality of Oligo Lactic Acid [LAC] is stable thanks to the production process in which only L-type lactic acid is condensed and processed.
