The invention relates to the field of
food processing, and particularly discloses low-
calorie margarine and a preparation method thereof. A preparation method of low-
calorie margarine comprises the following steps: taking
plant raw materials, cleaning,
drying until the
moisture content is less than or equal to 8%, and crushing until the particle size is 100 meshes to prepare coarse
powder; dispersing the coarse
powder into water to form a coarse
powder dispersion liquid, and circularly
grinding to obtain a
plant particle dispersion liquid; the
plant particle dispersion liquid is subjected to primary ultrasonic treatment, salt is added after ultrasonic treatment, the
ion concentration is made to be 300-600 mM, then ultrasonic treatment is conducted again, and a water-phase liquid containing porous micron particles is prepared; the preparation method comprises the following steps: mixing saturated oil and unsaturated oil, injecting an aqueous phase liquid containing porous micron particles, and enabling the addition amount of the aqueous phase liquid to be 30-50%, so as to prepare a crude
emulsion; and shearing the crude
emulsion,
quenching and kneading, aseptically packaging and
ripening. The margarine provided by the invention has the advantages that the
water content is as high as 30-50%, the
oxidation resistance is strong, and the
shelf life is long.
