Microencapsulated Oil Powders

The powdered product formed by encapsulating functional oils (such as unsaturated fatty acids, plant oils, structured lipids) within natural or synthetic polymer wall materials through microencapsulation technology, typically has an oil-in-water (O/W) microstructure configuration. The core process involves utilizing wall materials (e.g., proteins, starches, cellulose derivatives) to encapsulate liquid oils into micron-sized capsule particles via spray drying or coacervation techniques, thereby enabling the oils to be uniformly dispersed as tiny oil droplets in the wall material matrix and forming a free-flowing powder. With its unique "powdered oil" properties, microencapsulated oil powder not only preserves the functional activity of the oils but also offers the processing convenience of solid materials, making it a crucial technological means for efficient utilization of oils in the food and health sectors.

Classification

The wall material systems for microencapsulated oil powders can generally be divided into two major categories based on
the source of the matrix wall material:vegetarian and non-vegetarian.

Vegetarian Wall Materials

Plant-based proteins

Soy protein isolate, pea protein, wheat protein, etc.

Starch/polysaccharides

Natural starches (corn, tapioca, potato starches)

Modified starches (maltodextrin, cyclodextrin, sodium carboxymethyl cellulose, etc.)

Plant-based colloids (gum arabic, xanthan gum, etc.)

Non-vegetarian Wall Materials

Animal-based proteins

Gelatin (derived from cattle/pig skin and bones), whey protein (from bovine milk), sodium caseinate (from bovine milk), etc.

Composite systems

Animal protein combined with plant polysaccharides (gelatin–gum arabic)

Core Features and Advantages

Significantly Enhanced Stability

· The barrier formed by the wall material effectively isolates oxygen, light, and moisture, inhibiting lipid oxidation and rancidity, thereby extending shelf life.

Optimized Functional Properties

· Improved Taste and Odor: It masks the inherent fishy smell, greasiness, or undesirable flavors of oils, enhancing product palatability.

· Enhanced Dispersibility and Solubility: The powdered form enables easy mixing with water-based systems (e.g., beverages, dairy products) and rapid dissolution to form stable emulsions.

· Controlled and Targeted Release: By adjusting the composition and structure of the wall material, controlled and targeted release of oils (e.g., intestinal-targeted absorption) can be achieved, improving bioavailability.

Broad Process Adaptability

· Wall material combinations (e.g., polysaccharide-protein complexes) can be customized according to oil characteristics, ensuring encapsulation efficiency.

· Strong Processing Resistance: Suitable for complex processes such as high-temperature (e.g., baking) and acidic environments while maintaining structural integrity.

Diverse Application Scenarios

· Food Industry: Serves as a nutritional fortifier in solid beverages, baked goods, etc., addressing challenges in oil incorporation.

· Health Supplements and Pharmaceuticals: Used for microencapsulation of nutritional oils and oil-soluble active ingredients to improve convenience and stability for consumption.

· Feed and Agriculture: Enhances oil dispersibility in aquatic feed, increasing animal absorption rates.
