低糖南瓜馅料的配方优化研究

以南瓜、澄粉、木糖醇、花生油、糯米粉为原料,以黄原胶、海藻酸钠为辅料,制作低糖南瓜月饼馅料。通过单因素试验探讨木糖醇添加量、花生油添加量、澄粉添加量、熟糯米粉添加量对馅料感官评价的影响,利用响应面中心法则试验预测南瓜馅料的最佳配方。优化后的最佳配方为:木糖醇8.80%、花生油7.21%、澄粉8.95%、熟糯米粉2.15%、黄原胶0.4%、海藻酸钠0.2%。在此条件下馅料的总糖含量为17.4%,水分含量为35.17%,且口感具有弹性,黏牙感低,硬度适中。

Study on Formula Optimization of Low-sugar Pumpkin Stuffing

In this experiment,pumpkin,wheat starch,xylitol,peanut oil and glutinous rice flour were used as raw materials,xanthan gum and sodium alginate were used as subsidiary material to make low-sugar pumpkin filling.The effect of peanut oil addition,xylitol dosage,addition amount of wheat starch and added glutinous rice flour on sensory evaluation of fillings were studied by single factor experiment.The response surface center rule was used to predict the best recipe for pumpkin filling.The optimum formula was xylitol 8.80%,peanut oil 7.21%,wheat starch 8.95%,cooked glutinous rice powder 2.15%,xanthan gum 0.4%,sodium alginate 0.2%.Under these conditions,the total sugar content and moisture content of the fillings were 17.4%and 35.17%respectively.Moreover,the taste was elastic,with low stickiness and moderate palatability.
