When raw or air-dried vegetable foodstuffs, such as potatoes, sweet potatoes, carrots, rice, glutinous rice and so on, were treated with a solution of commercial cellulase preparation derived from the mold Trichoderma viride or Aspergillus niger, marked changes were caused in the cell walls of the parenchyma. According to microscopic observation, the cell walls were partly degraded or entirely removed by treatement with each enzyment with each enzyme solution including cellulase, carboxymethylcellulaes, xylanase and pectic enzymes. As a result largely of the removal of the cell wall and pectic substances, air-dried carrots treated by cellulase solution readily regained their original form when warm water was poured over them, and the tissues softened moderately without cooking. The same was true of glutinous rice to which boilig water was added. In starch production from potatoes, sweet potato, rice, glutinous millet and potato pulp, Asp. niger preparation capable of decomposing raw starch was inadequate for the porpose. However, thick mashing of air-dried sliced sweet potatoes or of sweet potato pulp for ethylalcohol fermentation may be performed successfully by the use of an Asp. niger cellulase preparation.
