1. Instant Agar Definition

Instant agar (also called quick soluble agar, and spreadable agar) is a hydrocolloid extracted from red seaweeds that is widely used in the food industry and in certain scientific and industrial applications. 

Instant agar is a significant breakthrough over the present commonly used stirred yogurt stabilizers in terms of usage, taste, and sensory status.

2. Commonly Used Stirred Yogurt Stabilizers

Name of Single HydrocolloidAdvantagesDisadvantagesGeneral Dosage
Agar-AgarThe good thickening effect, no stickyPoor solubility of common agar, limited by the yogurt production process0.05-0.2%
PectinFine taste, good stabilityLow viscosity, poor thickening effect, the sandy feeling when adding too much0.1-0.2%
GelatinSmooth and delicate surface, strong creaminessObvious viscosity decay above 15-20 degrees, allergenic animal source, not suitable for halal and vegetarian people0.2-0.6%
Modified StarchHigh viscosity, good water retentionNot shear resistant, rough texture, lack of gloss and smoothness0.5-2.0%
Whey ProteinIncrease protein content, water retentionHigh usage, high cost, lack of smoothness1.0-3.0%

3. What are the Purposes of Adding Yogurt Stabilizers?


Why is it necessary to add yogurt stabilizers to raw milk? The main purposes are as follows.

3. 1 To enhance and maintain good characteristics

To enhance and maintain good characteristics of yogurt, such as texture and structure, viscosity and consistency, appearance, and mouthfeel.

3. 2 To limit the production process

The function, mechanism of action, and the number of different yogurt stabilizers added directly affect the texture and taste characteristics of the products and limit the production process.

4. Breakthrough of Instant Agar

Instant agar is a significant breakthrough compared to yogurt stabilizers currently on the market in terms of usage, taste, and sensory status.

4.1 Taste

Sticky texture

Melt in the mouth, refreshing, fine, no drawing.

4.2 State

Fluid state

Stable state, short structure

4.3 Shear Resistance

Not good

Effectively resist mechanical shear, good recovery of late viscosity

4.4 Usage

The amount of commonly used yogurt stabilizer is high

But for instant agar, adding only 0.05-0.15% can obviously improve the quality of the yogurt and ensure the natural taste and flavor of yogurt.

5. Properties of Instant Agar

5.1 Compared with the normal agar

  • Good solubility, 65℃~85℃, 5~10 minutes to dissolve completely. The normal agar needs 100℃ and about 20 minutes. 
  • Transparency is better.
  • Not affected by the yogurt production process.
  • Good interaction with protein, effectively improving the taste and stability of yogurt. Whereas normal agar has an average effect on the improvement of yogurt quality.

5.2 Compared with other yogurt stabilizers

5.2.1 Instant agar has the best thickening effect, and a good thickening effect can be achieved with a lower addition.

Dosage/Viscosity of Stabilizers in Yogurt

*Viscosity measurement: Brookfield viscometer, 63# rotor, 5r/min, at 5℃.

5.2.2 Yogurt stabilizers can effectively prevent the loss of viscosity or hardness of yogurt products caused by an imperfect cold chain.

At about 20℃, the viscosity attenuation of yogurt with instant agar was significantly better than other stabilizers.

Effect of Stabilizers and Temperature on the Viscosity of Stirred Yogurt

*Yogurt stabilizer dosage (%): Instant Agar 0.15%, Pectin 0.2%, Other stabilizers 0.4%

5.2.3 The viscosity of stirred yogurt tends to decrease gradually with the extension of storage time, and the yogurt stabilizer can effectively slow down the decreasing trend of yogurt viscosity and maintain the stability of yogurt.

Instant agar has a good retention effect on the viscosity of stirred yogurt with minimal viscosity changes.

5.2.4 Instant agar can effectively resist mechanical shear and has good viscosity recovery properties, which can effectively improve the tissue state of stirred yogurt.
