The invention discloses a fruit and vegetable tablet containing lactic acid bacteria and a preparation method of the fruit and vegetable tablet. In the fermentation process of yoghourt, a functional fermentation agent, sprouted cargo rice, Chinese herbs extracts with cold and hot sensitivity resistance, and a stabilizing agent capable of effectively improving stability are added; the yoghourt is fermented under dynamic temperatures, so that the proliferation of lactic acid bacteria is maximized, and the cold and hot sensitivity resistance of the lactic acid bacteria is improved; a non-hot processing technique is adopted for pretreating the yoghourt and the pulp of fruits and vegetables so as to prevent microbial contamination during the process, increase the juice yield of the pulp of the fruits and the vegetables, increase the content of soluble cellulose in the pulp of the fruits and the vegetables, and prevent the pulp of the fruits and the vegetables from generating brown stains; a refrigerating protective agent which is scientifically compounded and has a better refrigerating resistant effect is added while mixing the pulp of the fruits and the vegetables as well as the yoghourt. Finally, the prepared fruit and vegetable tablet is fine and smooth in mouth feel, homogeneous in texture, stable in state, natural in quality, high in viable count, high in functionality, and long in quality guarantee period, and the viable count is 1.75 *1011-2.55 *1011CFU / g. Under the normal atmospheric temperature, the quality guarantee period of the fruit and vegetable tablet is 30-36 months.
