PURPOSE:To produce natural acetic acid without containing phenol, etc., unsuitable as a food from a protoplasm constituting a plant body of bamboo, bamboo grass, etc. CONSTITUTION:This method for producing acetic acid is composed of a juice pressing step for pressing juice from a leaf or a culm of bamboo or bamboo grass at a low temperature under a high pressure, a distilling step for distilling the pressed juice pressed from the juice pressing step and separating a liquid consisting essentially of the acetic acid as a distillate, polysaccharides, mineral components, etc., as a residue and a purifying step for purifying the liquid distilled from the distilling step and producing the acetic acid. Since the treatment is carried out at a low temperature of ordinary temperature throughout the whole process, phenols, etc., are not produced. Thereby, chemical components unsuitable for use as a food are not contained. Since chemical medicines, etc., are not mixed at all, the acetic acid is a safe natural food of good quality. |
