01Product Speculation
Two grades for low- and high-viscosity emulsions
Ecobel Plus and Ecobel HV are added in different proportions. Formulation shall be calculated on the basis of the type used and the active solid content of the product in the current batch.
NatFibra® Ecobel HV
For high viscosity emulsion, structures can be constructed in conjunction with multiple sugars, such as lusocolytes, or natural glues.
The cream, the milk, the structural emulsion.02Fibre structure
20-40 nm Microfibre Network
Bacterial cellulose forms a continuous 3D network in the aqueous phase
The unit consists of glucose units connected to β-1,4 glycosidic bond. Fibres have a diameter of about 20-40 nm and lengths above the μm scale, with high-aspect-ratio fibre interwoven in aqueous case.
The network can increase the structural intensity of successive emulsion, limiting the movement and concentration of oil droplets. Actual performance is influenced by product usage, pH, electrolyte, oil case composition and dairy processes.

01 / Valid solid content
0.08%-0.10% as an initial screening range for low-viscosity emulsions
Ecobel Plus passes the centrifuge test at 0.08% and 0.12% of the active solid content and does not pass at 0.04%. 0.12% The spray performance of the samples has decreased and the final usage still needs to be determined in conjunction with the target packaging and shelf stability.

02 / pH fit
Limited viscosity change, with centrifugal stability between pH 4 and 6
The test uses 0.08% effective solid content. Ecobel Plus passes the centrifugal test at pH 4-6 and shows a layer at pH 3. The viscosity change is not entirely consistent with centrifugal stability, and the target is subject to actual pH review.

03 / Nacl Fit
Structure retained at low salt levels; instability begins at 0.05% NaCl in this formulation
The test uses 0.08% effective solid content, and the system pH is 6. Ecobel Plus passes the centrifuge test at 0.005% and 0.025% NaCl and does not pass at 0.05% NaCl. Saltination shall be re-tested with actual ion composition.

04Microstructure
1280x microwatchThe oil droplets in the Ecobel Plus sample are clearer.
Observation uses 0.08% Ecobel Plus emulsion versus HEC against emulsion. Microconditions are 16x, magnifier 2x, mirror 40x.
Under this condition and observation, the boundaries of the oil droplets in the Ecobel Plus sample are clearer, and the concentration, integration and irregular concentration of the droplets is less than the HEC control samples.

06Formulation Process
Disperse the microfibrils before building the emulsion structure
- 01
Predispersion
3000 rpm mean 3-10 min, until the slurry is 100% transparent and non-physically visible particles.
- 02
Build the aqueous phase
Add the rest of the aqueous pase group to dispersed cellulose gel, which is continuously broken to even.
- 03
Cold-process emulsification
Low-speed stirs slowly add an oil case to 5,000 rpm mean 3-5 min.
- 04
Hot-process emulsification
Oil case and aqueous case maintain 70-75°C and mix cooling after high-speed parity.
- 05
Post-addition
Cool to 35-40°C, add thermal sensitivity and regulate pH.
07Usage and authentication
Calculate product dosage from effective solids
Low viscosity emulsion uses 0.08-0.10% effective solid content as the initial screening range. Reference 9% (0.09% solid content) of the reference is an example of product addition, which should be converted according to the model used and the active solid content of the current product.

- Oil case ratio and oil type
- Emulsifiers combined with natural glue
