Estimation of apparent glass transition temperature from the release of 1-methylcyclopropene included in α-cyclodextrin

The glass transition temperature (Tg) is an important physical property affecting the release of 1-methylcyclopropene (1-MCP) from its inclusion complex with α-cyclodextrin (α-CD). The release of 1-MCP from α-CD was investigated using humidity ramping at constant temperature and temperature ramping...

Description
Summary:The glass transition temperature (Tg) is an important physical property affecting the release of 1-methylcyclopropene (1-MCP) from its inclusion complex with α-cyclodextrin (α-CD). The release of 1-MCP from α-CD was investigated using humidity ramping at constant temperature and temperature ramping at constant humidity. The apparent Tg values of α-CD were estimated from the collapse temperatures observed in the release experiments and compared with the temperatures calculated using the Gordon-Taylor equation. Good agreement between the estimated and calculated Tg values indicated that the ramping method for flavor release from a powder matrix would be a simple and effective approach to estimate the Tg of the matrix.
