Trehalose, also known as α-D-glucopyranosyl, α-D-glucopyranoside, is a disaccharide molecule made up of two glucose molecules linked with a 1, 1 glycosidic linkage. It is mostly found in a variety of organisms ie, bacteria, fungi, invertebrates etc (Himei 2008). Although trehalose was well known for carbon and energy source of plants and animals for years, the researches in the last two decades showed that trehalose is a multifunctional molecule as well. It is found in cell wall glycolipid as a structural component (Arguelles, 2000; Richards, 2002). Trehalose is very stable under hot and acidic conditions. Mizumoto et al (2004) showed that trehalose can be used as a bulk agent due to its stability towards heat and hydrolysis. Moreover, it does not caramelize and undergoes Maillard reactions and it is safe for human consumption and widely accepted by the European regulation system (Richards et al., 2002; Schiraldi,
