The invention discloses normal-temperature drinking type yoghourt and a preparation method thereof. The normal-temperature drinking type yoghourt comprises the following raw materials in percentage by weight: 56.6%-60% of concentrated
raw milk, 1*10<6>-7*10<9>cfu / mL of a fermenting agent, 0.03-0.5% of a stabilizing agent, a proper amount of a
sweetening agent and a proper amount of water, wherein the stabilizing agent is selected from one or multiple of
pectin, soybean
polysaccharide and
gellan gum, and the percentage is the
mass percent of the stabilizing agent, accounting for the total
mass of the normal-temperature drinking type yoghourt. The preparation method comprises the following steps: (1) homogenizing the concentrated
raw milk and milk
powder and sterilizing to obtain a sterilized liquid mixture A; (2) cooling, adding the fermenting agent for
fermentation, overturning a
jar by
back pressure, homogenizing and cooling again; (3) uniformly mixing with the sterilized liquid mixture A, adjusting the acidity, homogenizing so as to obtain a liquid mixture B, wherein the liquid mixture A comprises the stabilizing agent, the
sweetening agent and the water; and (4) sterilizing the liquid mixture B. The normal-temperature drinking type yoghourt and the preparation method disclosed by the invention have the advantages that the requirements of heat treatment for the
viscosity of the yoghourt and the adding amount of the stabilizing agent are effectively reduced, the obtained normal-temperature drinking type yoghourt is good in fluidity and smooth in taste and has no obvious layering condition after being stored for 6 months under the normal temperature.
