The invention discloses anti-aging pre-baked bread containing composite collagen anti-freeze peptide and plant hydrophilic colloid and a preparation method of the bread. The preparation method comprises the steps that 1, yeast is activated at constant temperature; 2, plain flour, ask gum, tamarind gum, scatophagus argus fishskin anti-freezing polypeptide powder and salmon fishskin anti-freezing polypeptide powder are evenly mixed; 3, liquid ferment and the mixture obtained in step 2 are mixed with water and stirred to be soft until a gluten film appears; 4, sodium chloride and a yeast water solution are added and stirred to obtain dough; 5, after primary standing, exhausting, relaxation and secondary standing are carried out on the dough obtained in step 4, the dough is cut into blocks orshaped in a specific shape; 6, fermenting is conducted; 7, a pre-baked bread semi-finished product is obtained; 8, the anti-aging pre-baked bread containing composite collagen anti-freeze peptide andplant hydrophilic colloid is obtained. On the one hand, mechanical damage of ice crystals to the pre-baked bread is reduced, and therefore the anti-aging capacity of the bread is improved; on the other hand, the stability of the net structure of gluten is improved, and the strength of the gluten is improved.
