<p>A method of evaluating the physical strength of the skin of raw barley for malt production. Barley grains with skins are placed in a sulfuric acid solution of about 40 to 60% concentration and stirred by means of a stirrer bar, etc. for a given period of time (for example, about 1 hr). After the completion of stirring, the barley grains are treated with a liquid mixture of methylene blue and eosin, and the degree of skin peeling (degree of residue) is assessed on the basis of staining degree. Thus, the physical strength of the skin of raw barley is evaluated.</p> |
