Practice has demonstrated, however, that the methoddescribed is the more accurate. To ascertain the purity of the juice, the procedure is as fol-lows : A part of the shredded sample is taken and the juice issqueezed out of it. The amount of sugar in this juice is deter-mined by aid of the polariscope
