Abstract

The invention discloses a walnut oil yoghourt. The walnut oil yoghourt is prepared from, by weight, 100 parts of milk, 5 parts of walnut oil, 6 parts of saccharose, 0.2 part of sucrose ester, 0.05 part of polyglycerol fatty acid ester and 0.05 part of lauric acid. According to the preparation method, 2-4 parts by weight of lactobacillus paracasei are inoculated into milk, then fermenting is conducted at 41 DEG C, and emulsified walnut oil is added when fermenting is carried out for 2 hours. According to the invention, the proportion of components of the walnut oil yoghurt is optimized, when the proportion of the component of the walnut oil is 5%, the total number of probiotic colonies reaches the maximum of 1.8*10<7>CFU / g, and at the moment, the effect of the walnut oil of promoting the proliferation of the lactobacillus paracasei is maximized, so that the nutritional value of the walnut oil yoghurt is improved; and besides, the emulsion system of the walnut oil yogurt formed by usingthe proportion of the above emulsifier is stable, and the finished product has better sense.
