TIANJIANG / MOONCAKE FILLING FORMULATION
Mooncake Filling Formulation with Modified Starch
This mooncake filling formulation platform uses Tianjiang modified starch to help manufacturers control moldability, water migration, bake stability, oil separation, post-bake softness and smooth texture across fruit, mung bean and traditional paste-style mooncake fillings.

01 / DEFINE THE FILLING TARGET
Mooncake Filling Solutions for Manufacturers and R&D Teams
Define the mooncake style, filling-to-skin ratio, fruit or bean base, sweetener system, baking conditions, forming equipment and target shelf texture before selecting the starch grade.
Forming and Moldability
Develop enough body for automatic wrapping, molding and pattern definition without creating an excessively hard filling.
Water and Oil Management
Control free moisture and oil migration to protect the crust and maintain filling uniformity during storage.
Commercial Production Consistency
Connect laboratory texture with mixing, heating, forming, baking and finished-product conditions on the production line.
02 / FOUR MARKET-RELEVANT FILLING SYSTEMS
Four Mooncake Filling Formulation Platforms
Tianjiang's core fruit-filling formula is expanded into four platforms covering fruit-forward, lower-sugar, fruit-and-bean and traditional paste-style products.

Classic Fruit Mooncake Filling
The core Tianjiang platform based directly on a high-fruit, syrup, sugar, vegetable-oil and modified-starch system.

Reduced-Sugar Fruit Filling
A fruit-forward development platform using maltitol syrup to reduce conventional added-sugar contribution.

Fruit & Mung Bean Filling
Combines fruit flavor with a smooth mung-bean base for modern baked or snow-skin mooncake concepts.

White Lotus Seed Paste Filling
A traditional-style filling platform in which a low starch level supports water management and processing consistency.
Reduced-sugar claims, preservative use and product naming must be confirmed against the regulations of the destination market.

04 / MODIFIED STARCH PERFORMANCE
How Modified Starch Supports Mooncake Filling Texture and Stability
The objective is not to make the filling harder. The objective is to build a controlled filling matrix that remains workable, moldable and stable through manufacturing and storage.
Water Binding
Reduce free water and help control moisture migration from the filling into the mooncake skin.Moldability
Support sufficient body for automatic filling, wrapping and pattern-forming equipment.Bake Stability
Help the filling maintain structure under high-temperature mooncake baking conditions.Smooth Mouthfeel
Build viscosity without creating excessively tough or gummy texture.Heat and Shear Resistance
Maintain useful viscosity through kettle processing, agitation and pumping.Shelf Texture
Select stabilized starch to reduce excessive retrogradation, hardening and syneresis.
05 / COMMERCIAL MANUFACTURING
Mooncake Filling Manufacturing Process
Tianjiang's process develops the modified starch under controlled heating, concentrates the filling to the required solids, and adds the acid system near the end of processing.
TJ-MF Recommended Production Sequence
-
Weigh all ingredients
Prepare fruit or paste base, sweeteners, vegetable oil, Tianjiang modified starch, water and supporting ingredients according to the batch sheet.
-
Prepare the starch dispersion
Disperse Tianjiang modified starch into process water or preblend it with part of the sugar to minimize agglomeration.
-
Build the filling base
Add fruit, bean or lotus paste, syrup and sugar under controlled agitation until uniform.
-
Incorporate vegetable oil
Add soybean or approved vegetable oil gradually while mixing to achieve uniform distribution.
-
Heat to develop the starch
Raise the filling to approximately 90–95°C under continuous agitation until the starch is fully developed.
-
Concentrate to target solids
Continue controlled heating until the required soluble-solids or moisture target is achieved.
-
Adjust final acidity
Add the approved acid system near the end of the main heating stage and mix uniformly.
-
Fill, cool and condition
Transfer under the validated plant process, cool, then condition before forming or packaging.



Exact temperature, hold time, final solids, water activity and packaging controls must be validated for the specific fruit, bean or lotus raw materials and the intended shelf-life system.
06 / CONTROL THE COMPLETE MOONCAKE SYSTEM
Moldability, Water Migration and Bake Stability
A filling can look correct in the kettle and still fail during wrapping, molding, baking or shelf storage.
Moldability
Evaluate whether the filling forms cleanly without sticking, smearing or losing the mooncake pattern.
Water Migration
Monitor moisture movement from the filling into the crust during storage.
Bake Stability
Record collapse, cracking, sidewall deformation and filling leakage after baking.
Post-Bake Softness
Compare filling firmness after cooling and throughout the intended shelf life.
07 / DIAGNOSE THE FILLING FAILURE
Mooncake Filling Formulation Troubleshooting
Do not solve every problem by adding more starch. Moisture, soluble solids, oil content, cooking, filling temperature and baking conditions can all change performance.
| Observation | Factors to Investigate | Controlled Next Trial |
|---|---|---|
| Filling is too soft for forming | Moisture, soluble solids, starch level or incomplete starch development. | Confirm final solids before increasing starch. |
| Filling becomes too hard after storage | Starch retrogradation, low moisture, high solids or excessive cooking. | Compare a more stabilized starch at identical final solids. |
| Water migrates into the crust | High water activity, weak water binding or insufficient concentration. | Measure filling moisture and water activity before changing the starch dosage. |
| Oil separates from the filling | Oil level, mixing, paste composition or weak continuous phase. | Review oil-addition sequence and mixing conditions. |
| Mooncake collapses during baking | Low filling strength, high moisture, bake profile or weak skin-to-filling balance. | Run a controlled bake test with identical filling weight. |
| Filling cracks during baking | Excessive firmness, low moisture, high solids or rapid heating. | Reduce filling rigidity before increasing oil. |
| Texture becomes sticky | High syrup, low solids, incorrect starch or insufficient cooling. | Standardize solids and conditioning temperature. |
| Snow-skin filling separates after freezing | Freeze-thaw instability, water release or starch selection. | Compare freeze-thaw-stable modified starch grades. |

11 / TECHNICAL QUESTIONS
Mooncake Filling Formulation FAQs
Practical guidance for mooncake manufacturers, filling producers, R&D teams and ingredient buyers.
How Much Modified Starch Is Used in Mooncake Filling?
Tianjiang's original fruit-filling application range is approximately 0.5% to 1.0% modified starch. The reference formulas on this page use 0.60% to 0.90%, depending on the filling base and target texture.
What Does Modified Starch Do in Mooncake Filling?
An appropriate modified starch can support water binding, moldability, heat stability, texture control and reduced moisture separation.
Why Does Mooncake Filling Become Hard During Storage?
Potential causes include starch retrogradation, excessive solids, moisture loss, over-cooking or an unsuitable starch grade.
How Can Water Migration Into Mooncake Skin Be Reduced?
Control the filling's moisture, water activity, soluble solids and water-binding system. Modified starch can be part of this strategy, but the complete filling and crust system must be evaluated.
Can Modified Tapioca Starch Be Used in Mooncake Filling?
Yes. Appropriate modified tapioca starch can provide smooth mouthfeel, process tolerance and useful water management. The exact grade should be selected for the filling and process.
Can Modified Starch Be Used in Lotus Seed Paste?
A low modified-starch level can be evaluated to support consistency and water management, but it should not mask the characteristic lotus-paste texture or flavor.
Can Modified Starch Be Used in Snow-Skin Mooncakes?
Yes. For frozen or chilled snow-skin mooncakes, select a grade with appropriate freeze-thaw stability and refrigerated shelf-life performance.
Why Is Acid Added Near the End of Processing?
Late acid addition reduces the time the starch spends under simultaneous high-temperature and low-pH conditions, which can help preserve finished viscosity.
What Information Should I Send Tianjiang?
Share the filling type, fruit or bean percentage, sweetener system, oil content, current starch, final solids, water activity, cooking process, baking conditions and target shelf texture.
