Vinegar syndrome

CA has been widely nsed to copy cinema film images off old supports of CA or CN. However, much of the film stock used has deteriorated severely by metal-catalysed degradation and hydrolysis of the polymer (Allen et al., 1992), the vinegar syndrome . The predicted lifetime of many CA films is c. 40 years, depending on the manufacture and storage conditions (Adelstein et al., 2002). 

Avoid foods that may generate dryness Patients who suffer from the syndrome of dryness should avoid spicy food and food that induces heat, such as hot pepper, onion, cinnamon and deep-fried food. Very sour food, such as citrus fruits and vinegar, should not be consumed in excess as they may make the fluid distribution slow or even stop.
