The glassy state in certain sugar‐containing food products *

Summary A review is given of the literature on organic glasses with special reference to sugar glasses. The amorphous sugar glasses in boiled sweets, milk powder, ice cream and certain freeze-dried products are then discussed. Breakdown of these sugar glasses can lead to defects in all four cases.
