Abstract: The present invention discloses an antifreeze solution for food preservation, which comprises edible alcohol, propylene glycol, glycerin, calcium chloride, sodium chloride, amino acid, Antarctic krill protein hydrolysate with an average molecular weight of 50-100 KDa, surfactant and water, wherein the surfactant is one or more of phospholipid, Tween-20, Tween-60, and Tween-80; each component is food grade, and the mass percentage is expressed as follows: alcohol 15-30%, propylene glycol 10-30%, glycerol 2-15%, calcium chloride 1-10%, sodium chloride 3-10%, amino acid 0.1-0.15%, Antarctic krill protein hydrolysate 0.01-0.3%, surfactant 0.005-0.5%, and the balance is water. The antifreeze solution provided by the present invention can lower the freezing point, improve the heat transfer efficiency, inhibit the crystallization of antifreeze solution during the low temperature stirring process and improve the stability of the antifreeze solution.
