The other assumption is trehalose’s glass-forming ability[14]. It insists that trehalose can form glassy state
and resemble glass state of ice after its glass transition temperature (Tg), and then it packs biological molecule
tightly. The result is that the molecule has enough space in losing water case to resist destroy of harmful
surroundings. And this transition to the glassy state or the vitrification theory has been put forward as the
most widely accepted hypothesis to explain the bioprotective action of trehalose. No matter which point was
right, it could not influence its application. For example, Experiments have confirmed that it could help
treating dry eye[15].
