TIANJIANG / FLAVOR DELIVERY TECHNOLOGY
Flavor Microencapsulation with OSA Modified Starch
Volatile flavor oils can lose intensity, oxidize, separate or become difficult to handle during processing and storage. Tianjiang OSA modified starch helps manufacturers convert oil-soluble flavor and aroma systems into stable emulsions before spray drying. The resulting microencapsulated flavor powder can provide improved aroma retention, controlled oil loading, powder handling, storage stability and easier incorporation into dry food systems.
01 / WHAT FLAVOR MANUFACTURERS ACTUALLY NEED
Flavor Microencapsulation for Commercial Powder Systems
Flavor microencapsulation is not simply “oil plus carrier.” The complete system must manage oil-in-water emulsion stability, droplet size, feed viscosity, volatile retention, wall-to-core ratio, spray-dryer behavior, surface oil, powder flow and aroma stability during storage.
Stable Flavor Emulsion
Keep citrus, mint or aroma oils uniformly dispersed before atomization.
Volatile Aroma Retention
Reduce unnecessary loss of valuable volatile compounds during drying and storage.
Controlled Oil Loading
Balance flavor intensity against wall protection, feed viscosity and powder behavior.
Oxidation Protection
Reduce direct exposure of sensitive flavor oils to oxygen, light and environmental stress.
Efficient Spray Drying
Control feed solids and viscosity for stable atomization and practical dryer throughput.
Free-Flowing Powder
Target controlled moisture, low caking and consistent downstream blending.
BOTANICAL INGREDIENTS
Botanical Oils & Powder Formats
Ingredient examples for flavor development. A botanical powder is not necessarily microencapsulated; each oil or extract requires its own carrier selection and processing trials.
Turmeric Oil & Botanical Powder
Explore botanical oil and powder formats for flavor and color development. Validate dispersion and aroma retention for the selected ingredient.
Star Anise & Spice Aromas
Assess spice-oil delivery in savory flavor systems, with attention to emulsion stability and aroma changes during drying.
02 / FOUR COMMERCIAL DIRECTIONS
Four Flavor Microencapsulation Development Platforms
The Tianjiang platform covers sweet orange, higher-load citrus, peppermint / mint and high-volatility food-grade aroma oils.
Sweet Orange Flavor Microcapsule Powder
A balanced version of Tianjiang's supplied internal sweet-orange microencapsulation platform using OSA starch, maltodextrin and spray drying.
High-Load Citrus Flavor Powder
A higher-core-loading direction for orange, lemon, lime, mandarin and similar oil-rich citrus flavor systems.
Peppermint & Mint Flavor Powder
A volatile mint-oil delivery platform designed around emulsion stability, aroma retention and controlled spray-dried powder loading.
High-Volatility Aroma Oil Powder
A stronger-wall platform for food-grade aroma oils, spice notes, savory flavor oils and other highly volatile flavor systems.
TJ-FF-01 is built directly from the Tianjiang internal formulation range provided for sweet orange flavor powder. TJ-FF-02 through TJ-FF-04 are independently developed commercial-scale starting points informed by Tianjiang's process platform, public flavor-encapsulation technology and spray-dried flavor system architecture. They are not reproductions of another manufacturer's proprietary formula.
03 / SPRAY-DRYING FORMULATION CALCULATOR
Flavor Microencapsulation Batch Calculator
Scale the emulsion, adjust flavor-oil loading, modify Tianjiang OSA starch and maltodextrin, estimate spray-dried powder recovery and calculate the theoretical flavor concentration of the finished powder.

Powder recovery and theoretical flavor loading are mass-balance estimates. Actual volatile retention, surface oil, encapsulation efficiency, aroma profile and shelf-life stability must be measured analytically after spray drying.
04 / FLAVOR DELIVERY FUNCTION
Why OSA Modified Starch for Flavor Microencapsulation?
Flavor oils are hydrophobic, while commercial spray drying normally begins with an aqueous feed. An appropriate starch sodium octenyl succinate helps bridge that incompatibility, supporting oil-in-water emulsification and creating carbohydrate solids that participate in the protective powder matrix.
Flavor Oil Emulsification
Support the dispersion of hydrophobic flavor oil inside an aqueous continuous phase.Low Feed Viscosity
Suitable grades can help maintain practical viscosity at commercially useful solids.Fine Droplet Formation
Work with high-shear and homogenization equipment to build a controlled emulsion.Film Formation
Contribute to a carbohydrate matrix around flavor-oil droplets during drying.Volatile Protection
Help reduce exposure of sensitive flavor compounds during storage.Carrier Compatibility
Combine with maltodextrin to adjust feed solids, powder characteristics and formulation economics.

08 / DIAGNOSE THE PROCESS FAILURE
Flavor Microencapsulation Troubleshooting
Keep flavor oil, total solids, homogenization history and spray-dryer conditions constant when comparing different wall materials.
| Observation | Likely Factors | Controlled Next Trial |
|---|---|---|
| Flavor oil separates before drying | Insufficient emulsification, incomplete OSA hydration, coarse droplets or excessive core loading. | Screen a Tianjiang OSA grade at constant core/wall ratio and homogenization conditions. |
| Feed viscosity is too high | High wall-material concentration or unsuitable OSA / maltodextrin balance. | Adjust the wall ratio before reducing total feed solids. |
| High surface oil | Coarse emulsion, weak wall coverage, excess core or inappropriate drying. | Improve emulsion quality before increasing dryer temperature. |
| Aroma is weak after drying | Volatile loss during atomization or thermal exposure. | Review droplet size, drying profile and wall-to-core ratio. |
| Orange / citrus note oxidizes | Surface oil, oxygen exposure or weak barrier performance. | Measure surface oil and conduct controlled oxidative shelf-life trials. |
| Powder sticks in dryer | Feed solids, outlet conditions, wall composition or product stickiness. | Optimize formulation and dryer mass balance together. |
| Powder cakes during storage | High moisture, humidity exposure or insufficient powder finishing. | Review moisture, packaging and anti-caking system. |
| Batch aroma varies | Flavor-oil variation, emulsion drift or inconsistent spray-drying conditions. | Define release limits for feed viscosity, droplet size and emulsion stability. |

10 / TECHNICAL QUESTIONS
Flavor Microencapsulation FAQs
Technical guidance for flavor houses, spray-drying plants, food ingredient manufacturers, R&D teams and procurement professionals.
Why Is OSA Modified Starch Used for Flavor Microencapsulation?
OSA modified starch has hydrophilic and hydrophobic functionality, allowing an appropriate grade to help stabilize oil-in-water flavor emulsions while also contributing carbohydrate solids to the spray-dried matrix.
Which Flavors Can Be Microencapsulated with OSA Starch?
Typical candidates include orange, lemon, lime, mint, essential-oil flavors, savory oils, spice aromas and other hydrophobic food flavor systems.
Why Combine OSA Starch with Maltodextrin?
OSA starch provides important emulsifying and film-forming functionality, while maltodextrin can be used to adjust total solids, feed viscosity, powder properties and formulation economics.
Can OSA Modified Starch Increase Flavor Oil Loading?
Suitable grades can support useful oil loading, but the practical maximum depends on flavor chemistry, wall-to-core ratio, feed solids, homogenization and spray-drying conditions.
Why Does Citrus Flavor Lose Aroma During Spray Drying?
Citrus oils contain highly volatile components. Droplet size, wall coverage, atomization, drying profile and surface oil all influence aroma retention.
What Is Surface Oil in Spray-Dried Flavor Powder?
Surface oil is flavor oil located at or readily accessible from the particle surface. High surface oil can contribute to oxidation, aroma loss, stickiness and reduced storage stability.
Is More OSA Starch Always Better?
No. Excessive wall material may reduce flavor loading and can change feed solids, viscosity and final powder economics. The wall-to-core ratio should be optimized for the actual flavor system.
What Information Should I Send Tianjiang?
Provide the flavor type, oil composition, target powder loading, feed solids, existing wall system, homogenization equipment, spray dryer, finished application and shelf-life requirement.
