White crystals, volatile with steam.
1.2% in water, 1.2% in glycerine, 2.8% in propylene glycol, 3.3% in ethyl alcohol, 5.0% in phenylethyl alcohol, very poorly soluble in terpenes and most other hydrocarbons.
Warm-fruity, caramellic-sweet odor with emphasis on the caramellic note in the dry state, while solutions of Maltol show a pronounced fruity, jam-like odor of pineapple, strawberry type.
Intensely sweet, fruity, jam-like, pineapple-strawberry type flavor with caramellic undertone.
Maltol is commonly used in perfume compositions, but only in very low concentrations. Its effect in pine needle type fragrances is well known and widely used, and its warm-sweetening effect in rose undertones is also highly appreciated. As a trace component in fruity lipstick fragrances, often with undecanolide, ethylmethylphenylglycidate, ionones, etc. it finds extensive use.
Its main use is, however, in flavor compositions, not only as fruity component in pineapple and strawberry, but in general as a sweetener. Its flavor is clearly perceptible at concentrations near 5 ppm, and the concentration in finished products is normally about 5 to 25 ppm in beverages, 40 to 170 ppm in marmalades, 100 to 200 ppm in concentrated soups, 50 to 250 ppm as a general flavor enhancer.
1) (biosynthesis): by alkaline hydrolysis of streptomycin salts. 2) (chemical synthesis): from pyridine via piperidine to pyromeconic acid. The 2-methyl-derivative is Maltol.
