INDEX Diacetyl

Most of the isolated diacyl (including sulfonyl) peroxides are solids with relatively low decomposition temperatures, and are explosive, sensitive to shock, heat or friction. Several, particularly the lower members, will detonate on the slightest disturbance. Autocatalytic (self-accelerating) decomposition, which is promoted by tertiary amines, is involved [1]. Solvents suitable for preparation of safe solutions of diacetyl, dipropionyl, diisobutyryl and di-2-phenylpropionyl peroxides are disclosed [2], The class is reviewed, including hazards and safety measures [3], Cyclic diacyl peroxides are more stable, but scarcely to be trusted. Individually indexed compounds are ... 

Esteve et al. (2005) studied the physicochemical and quality characteristics of various minimally pasteurized refrigerated Spanish orange juices, and their changes with storage time and temperature. Except for pH, all the characteristics studied (essential oils, acidity, color, conductivity, density, diacetyl index, and viscosity) varied with storage time at 4 and 10°C, but density variation was not statistically significant at 4°C.
