The invention provides a concentrated peach juice product and a preparation method. The concentrated peach juice is a concentrated juice which is prepared by adopting sodium D-isoascorbate to fix the color and pectic enzyme, amylase and protease to carry out hydrolytic treatment; the content of the solvable solid matter of the concentrated peach juice product is 40 percent to 60 percent and the pH value equals to 3.8 to 4.2. One important contribution of the invention lies in that the crushing of peaches is realized on the base of the selection of the color fixative, thereby greatly improving the color index of the concentrated peach juice, meanwhile, pectic enzyme, amylase and protease are utilized to hydrolyze the peach juice, thereby finally obtaining a concentrated peach juice product with high nutritive value, stable properties and good flavor and taste by adopting the techniques such as adsorption and hyperfiltration. Edulcorator and preservative need not to be added into the concentrated peach juice pr
