Studies On The Manufacture Processing Of Instant Edible Pumpkin Powder

In this paper, status quo about the processing and utilization of pumpkin in China was introduced, and the problem about which was put award. Based on them, a new processing way was provided. The dry powder was comminuted and expanded. The nutritional substances in pumpkin were used richly, and the characters of dissolution and dainty were improved by the extrusion expanded process, the instant edible pumpkin powder. A low price, convenient edible, whole nutrition, crude, health care food was get, that was instant edible powder.The processing of instant edible powder was studied. The main factors that effected the expanded degree of instant edible powder were the station of expander's screw, expanded temperature, the formula of the raw material and the water content of the raw material. They were investigated by the analysis in theory and optimizing experiments, and the optimum parameters about the production of instant edible in Model P400 expander were indicated.Based on the studies of the principle about the dissolution characters and agglomeration of powdery foods, the mensuration of dissolution characters of instant edible pumpkin powder was brought forward. The effects of the comminuting granularity of instant edible pumpkin powder on its dissolution characters were studied via experiments. In the end, the content of nutritional substances in instant edible pumpkin powder was determined.
