This invention discloses a microfluidic method for preparing fish oil microspheres based on viscosity control and its application, belonging to the field of functional food preparation technology. The method involves constructing three viscosity systems (3.47–15.19 mPa·s) by compounding concentrated fish oil and castor oil at a specific volume ratio. Using a 3% polyvinyl alcohol aqueous solution as the continuous phase, water-in-oil fish oil microspheres are prepared under constant pressure in a cross-shaped microfluidic chip. By controlling the viscosity of the oil phase, the microsphere particle size can be precisely controlled within the range of 53.89–72.34 μm, with a coefficient of variation ≤5% and regular morphology. The obtained microspheres exhibit excellent particle size stability under pH 5–7 and 0–2% NaCl conditions. The high-viscosity microspheres show significantly lower acid values ​​and thiobarbituric acid reactant values ​​compared to the low-viscosity group under storage conditions of 4–60℃, with an oxidation stability improvement of over 30%. In vitro digestion experiments show that the low-viscosity microspheres reach peak free fatty acid release rate after 120 min, while the high-viscosity group exhibits a sustained-release effect. This invention achieves simultaneous optimization of fish oil microsphere particle size, stability, and digestive behavior, providing a theoretical basis and precise process parameters for the structured design of ω-3 polyunsaturated fatty acid functional foods.
