Abstract

Using nutritionally valuable products is important as people taste is going toward varies foods. The use of pumpkin can provide nutritionally qualified and valuable product, diversity of products and higher customer choice because it contains helpful and therapeutic compounds. In the current research, different levels of modified starch (0.2, 0.15, 0.1 percentage) and micro-crystalline cellulose (1.5, 1, 0.5 percentage) were used in the production of fruit butter for improving the consistency and the texture properties including hardness, toughness, gummy, cohesiveness, chewiness,…. and color attributes including three factors of L, a and b were evaluated. The results showed that the cohesiveness, gummy and hardness decreased with increasing the micro-crystalline cellulose. Furthermore, with increasing the modified starch increased the hardness, toughness, cohesiveness, chewiness, L and b parameters, but it had no effect on gummy, significantly. The pumpkin can be used as a natural and also enrichment combination in the process of the productions such as fruit butter due to its functional properties.
