Optimization of non- dairy dessert formulations based on pumpkin by Mixture Design

Pumpkins prevent the occurrence of all types of cancers due to the wealthiest micronutrients and high levels of 30% carotenoids. Regarding the high nutritional value and low consumption in the community, the primary objective of this research is to optimize the formulation of a new non-leavened dessert based on the pumpkin, which drives from hydrocolloids (Persian gum, xanthan, and carboxymethyl cellulose) in dessert formulation. In order to determine the dessert treatments, mixed design and software Design Expert 11 for three components of Persian gum (0-5%), xanthan gum (0-5%) and carboxymethyl cellulose (0-5%) use. After preparing the dessert, physicochemical tests (moisture, Dyeing, aw, and colorimetric) evaluate. The results showed that the lower humidity and water activity and the syneresis rate are more desirable that cause with decreasing xanthan and CMC and increasing Persian gum. Considering that more index b * is desirable in pumpkin dessert, so increasing the xanthan CMC and decreasing Persian gum cause the a* value be more and by decreasing xanthan and increasing CMC and decreasing Persian gum b* value was more.
