However, this process leads to the loss of organoleptic characteristics and essential thermolabile nutrients of fruits (Alibas et al. Traditional jam processing methods require concentration by heat treatments, primarily intended to inactivate enzymes, deteriorate microorganisms and reduce water activity by dehydration. Jam is an intermediate moisture food prepared by boiling different ingredients mainly fruit pulp, sugar, pectin and acid until obtaining a consistent product (Chauhan et al. Several processing methods are applied to preserve fruits, such as jam making, drying and fermentation (Touati et al. Nutritionists recommend the preservation of these compounds during fruit juice processing.

Orange is one of the most favorite fruit in the world. Since many types of fruits are seasonal with a short shelf life, they must be processed to keep the quality. There is an increasing demand for fresh fruits as well as their products. Keywords : Orange Jam Conventional heating Microwave Texture Colour. MW energy can be introduced successfully as an alternative method in the concentration process of orange jam. Spreadability texture test showed that MW processed samples presented lesser hardness and work of shear than CH processed samples. The Hunter parameters kinetics were more influenced by the MW process but no significant difference was found in the final product. Both models were found to describe the experimental (L, a, and b) kinetics adequately. Zero- and First-order kinetic models were applied to describe color change. The final jam concentration was in the range of 63☋rix was achieved in the range (70-110 min) for conventional heating and (12-23 min) for microwave processed samples.
