Gastrodia elata health-care yoghourt and preparation method thereof

The invention discloses gastrodia elata health-care yoghourt. The yoghourt is prepared from the following raw material components: fresh milk, gastrodia elata polysaccharide enzymatic hydrolysate, sugar and a yoghourt fermenting agent, wherein the mass ratio of the adopted fresh milk, the gastrodia elata polysaccharide enzymatic hydrolysate, the sugar to the yoghourt fermenting agent is 1:(0.05-0.1):(0.05-0.1):(0.02-0.05). The invention further discloses a preparation method of the gastrodia elata health-care yoghourt. According to the method, the enzymatic hydrolysate with the gastrodia elatapolysaccharide yield of 5.03% or above is obtained by optimizing enzyme reaction time, pH value and enzyme dosage, and then the content of soluble polysaccharide is increased. In coordination with the sugar and fermented yoghourt, the method can acquire the solidified gastrodia elata yoghourt which is fine and smooth in tissue, fine and uniform in curd, free of bubbles, good in taste and rich innutrients. 本发明公开了一种天麻保健酸奶，
