Abstract:The optimal formula and processing parameters of the epidermis and filling materials of a new kind of cake made of Chinese yam, tuckahoe, lotus seed and red jujube were studied by one factor and orthogonal test. The results showed that the optimal formula of epidermis was: Chinese yam powder 8.00%, tuckahoe powder 7.33%, sugar 14.67% and salad oil 6.67%. The best formula of filling materials was: sugar 20.00%, red jujube powder 20.00%, lotus seed powder 24.00% and citric acid 0.20%. The cake contained coarse polysaccharide 13.92% with good shap, uniformity colour, good texture and flavour. In addition, microbiology detection of the product showed bacteria count 10 and mildew colony 20, lower than the detection limits of the national standard.
