Abstract
Through the experiments of boiling sample pieces of whale meat in ethanol (15 vol% concentration) solution and in aqueous solution, both having the same concentration of glucose or sodium chloride, it was found that the weight of the boiled meat, and the water percentage, the water content and the dried matter in the boiled meat were larger with the meat in ethanol solution than in aqueous solution. The inorganic salts examined (sodium chloride, magnesium sulphate, sodium dihydrogen phosphate, calcium chloride and three kinds of polyphosphates) increased the estimated values mentioned above. The amount of dried matter in the boiled meat was directly proportional to the concentration of sodium chloride. On the other hand, other three values had maximum values at a certain concentration of sodium chloride. Among three polyphosphates, only sodium pyrophosphate had greater effects on the water percentage than sodium chloride. It was found with both ethanol solution and aqueous solution that the water percentage was inversely proportional to the concentration of glucose, while the weight and especially dried matter and solid matter were directly proportional to the concentration of glucose. The tendency found by glucose was obtained also by six kinds of carbohydrates and glycerine.
