Nicotinic acid and nicotinamide are soluble in water and alcohol; the properties of nicotinic acid and nicotinamide are relatively stable, and are not easily destroyed under acid, alkali, oxygen, light or heating conditions; under high pressure, 120 ° C, 20 min is not destroyed. General processing and cooking losses are small, but they are lost with water.
