The solution was allowed to temper for 16 h before it was mixed in the ASTM-recommended Hamilton Beach malt mixer for 1 min and transferred to a 1000 mL cylinder. Distilled water was added to the cylinder to create a 1000 mL suspension, and the tube was placed in a constant-temperature water bath. Only one cylinder was prepared at a time before starting the hydrometer analysis. A total of 29 samples were analyzed using this method (Tables T1, T2). Top of page \| Previous \| Next
