Lotus-root-starch-containing quick-energy-supply yoghurt melts and a preparation method thereof

The invention discloses lotus-root-starch-containing quick-energy-supply yoghourt melts and a preparation method thereof. The yoghourt melts comprise the following raw materials in parts by weight: 90-120 parts of whole milk powders, 20-40 parts of lotus root starch, 1-3 parts of lactic acid bacteria, 40-60 parts of mung bean starch, 5-8 parts of pistachio nut powders, 50-70 parts of maple syrup and 90-110 parts of straight-chain malto-oligosacharide. The preparation process comprises the following steps: weighing, mixing, preheating, homogenizing, sterilizing, cooling, inoculating, fermenting, mixing and emulsifying, congealing, paving on a tray and vacuum freeze drying and the like. A starch lipid compound is formed in the preparation process, so that the digestibility of starch can be reduced, and energy can be supplied to a human body for a long time. The yoghourt melts adopt lotus root starch which is rapid in energy supply and rich in calcium and iron and the straight-chain malto-oligosacharide which pr
