Abstract

Precipitation of a carbohydrate, such as trehalose, in a solution is prevented by mixing an effective amount of at least one antifreeze protein with the carbohydrate in the solution, wherein the antifreeze protein is in whole or in part one of SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, and SEQ ID NO: 4, and the antifreeze protein mass to the carbohydrate mass is between about 1:8000 and 1:30. The method is especially useful for improving the applications of a carbohydrate, such as trehalose, and the quality of the carbohydrate-containing products in industries by preventing crystallization of the carbohydrate in formulations and products.
