Handbook of Hydrocolloids: A Guide to Agar Agar

Agar is a seaweed hydrocolloid with a long history of use as a gelling, thickening, and stabilizing food additive.

The use of agar in foods is widespread throughout the Far East, including Japan, China, Korea, the Philippines, and Indonesia, and it has contributed significantly to the food customs in these countries for 350 years.

Agar could also be widely used for solid culture media in microbiology.

Properties

  • Strongest

    The strongest natural gelling agent.

  • Superior

    Agar Agar provides odorless, colorless superior quality gels even at very low concentrations.

  • Good

    Agar Agar has good synergies with sugar and with different hydrocolloids.

  • Versatile

    Agar Agar is versatile hydrocolloid completely soluble in boiling water.

  • Special

    Special Instant Agar powder can be dissolved at lower temperatures.

  • Reversible

    Agar Agar provides a thermoreversible gel.

  • Different

    Agar Agar gels at a temperature from 35 to 45C and melts at temperatures from 80 to 95C

  • Unique

    Agar Agar is the only hydrocolloid that gives gels that can stand sterilization temperatures.

1425 kJ (340 kcal);

slow resorption

Fibre content2.2% (42% protein, 36% carbohydrates)
Toxicology

No health concerns, consumption generally

1–2 g per day (mild laxative effect at 6 g per day);

no ADI value defined;

considered as food in Asia, not as additive

Solubility at low temperature (H2O)Insoluble
Appearance of an aqueous solutionOpaque, yellowish
Viscosity of solution in waterLow, insoluble in cold water
Impact of heat on viscosity in water (pH 7)Soluble at T>80 °C (176 °F)

Viscosity development in water at pH 7

(T=0–100 °C)

Forms a thermoreversible gel after dissolution

and cooling to 35 °C (95 °F) (gel melts at

T>85 °C (185 °F))

Shear stabilityHigh
Thickening effectHigh (gel formation)

Gelation

Thermoreversible gelation after heating to

T>80 °C (176 °F) and cooling to 35 °C (95 °F); also gels in saturated sugar solutions; gelation temperature is independent of sugar concentration

Synergistic effects with other hydrocolloids

+ LBG or guar: less syneresis, more elasticity;

+ 10% LBG: maximum gel strength (+8%);

+ 10% konjac: maximum gel strength

Other synergistic effectsEnhanced gel strength with high sugar concentrations (>60%) for some agar types

Negative interactions

Tannic acid can inhibit the gelling process;

gum karaya reduces gel strength of agar gels;

Proton scavengers like potassium iodide, urea,

Guanidine, sodium thiocyanate, and so on block the gelling process and prevent agarose gel formation

Dosage level in foodsLow, typical 0.5-2%, gelation already at 0.2%

Advantages

Compared with other hydrocolloids, Agar has many advantages, such as:

Plant-Based

A pure vegetable alternative to gelatin and it's perfectly healthy.

Gel hysteresis

The difference between the gelling and the melting temperature – which is around 50–60 °C (90–108 °F)

Low Dosage

Agar forms gels at very low concentrations (at 0.2%). The suggested use level in foods is quite low, typically 0.5-2%.

No cations Needed

Agar does not require cations to gel. Its solubility and gelation are not affected by the addition or presence of electrolytes.

Soluble Fibre

It has a high soluble fiber content that is not metabolized in humans and so it does not add calories to foods.

Benefits

Healthy: Low in calories, fat, sugar, and carbohydrates, but high in soluble fiber; Good for Weight Loss, Digestive Health, Bone Health, and Brain Health.

Vegan: Seaweed-based gums, the perfect substitute to animal-derived gelatin;

Gel performance: Firmer and stronger gel

Lab Use: It can not be degraded by the bacteria, so used as the preferred medium used in laboratories to grow bacteria.

Applications

This combination of benefits results in agar maintaining its position as the hydrocolloid of choice in a number of specific food applications, particularly where firm, short-textured gels with good heat stability and good moisture stabilisation are required.

FOOD APPLICATIONS:

  • Dairy Products
    Ice Creams, Puddings, Flans, Yogurts, Fermented Milk, Sorbets, Gelled Milk 
  • Sweets and Confectionary
    Gumdrops, Candy bars, Jelly candies, Jams, Marmalades, Comfitures, Dessert Gel, Meringues
  • Meat Products
    Pureed Meats, Canned fish, Poultry 
  • Beverages
    Clarifying and refining of juices, beers, wines and vinegars
  • Bakery
    Cake icings, Pie fillings, Bread dough, Chiffon pies

OTHER INDUSTRIAL APPLICATIONS:

Although agar has multiple applications, the traditional one is a food ingredient that accounts for 80% of its consumption. The remaining 20% is accounted for by biotechnological applications.

Agar-agar gel has the interesting property of inhibiting the characteristic liquefying that occurs in the enzyme action of microorganisms. This property finds a wide variety of applications in the medical and pharmaceutical industries.

Agar-agar is used as a substratum in preparing bacteria cultures in microbiology, as laxatives and therapeutic agents in the treatment of malfunctions of the digestive tract, as a retarding agent and carrier in the management of medicines, antibiotics, vitamins, as a barium sulfate suspension agent in radiology, as a stabilizer in cholesterol solutions, and as a suspension agent in several types of emulsions.

Agar-agar has other industrial applications as well where a gelling agent is needed, such as in dental prosthetics, photographic emulsions, differentiation of proteins through electrophoresis, chromatography through the exclusion of sizes, molding of materials and as plant culture tissues in biotechnology.

  • Medical and Pharmaceutical Industry
    Microbiology, Laxative, Therapeutic agent, Suspension agent of emulsion, Stabilizing agent of solution.
  • Other applications
    Dental prosthetics, Electrophoresis, Chromatography, Impression materials, Biotechnology
