Abstract: An emulsion gel embedding a fat-soluble vitamin and a pulsed electric field based production method therefor. The production method comprises: dissolving octenyl succinate starch ester in water, heating in a water bath, stirring to complete gelatinization and dissolution, and cooling to room temperature; adding edible oil dissolved with a fat-soluble vitamin to obtain a mixed liquid; shearing and homogenizing the obtained mixed liquid by using a high-speed shearing machine and a high-pressure homogenizer to obtain an emulsion; and adding the emulsion and natural starch to a methyl cellulose solution, performing pulsed electric field treatment after well mixing, heating in a water bath, performing degasification and cooling to obtain an emulsion gel. The pulsed electric field promotes interaction between methyl cellulose and starch molecules, has a higher elastic modulus, and is easier to form a network structure that is more conducive to embedding the fat-soluble vitamin.

Abstract: A method for improving frozen fish fillets treated by way of a salt-water immersion process includes the following steps: pretreating raw fish to obtain fish fillets; precooling the fish fillets; stacking the precooled fish fillets to obtain a fish fillet stack; freezing the fish fillet stack by using a salt-water immersion process, and performing power-variable ultrasonic wave treatment; and feeding the fish fillets into a cold storage, and performing freezing storage at minus 18 degrees centigrade. The power-variable ultrasonic wave treatment includes: firstly treating for 5 to 10 min under the power of 800 to 600 W, and then changing the power to 200 to 600 W for treating for 5 to 15 min. The freezing time of fish flesh is shortened, and formed ice crystals are fine and uniform, thereby preventing the damage of the formed ice crystals to cell walls.
