Agar Production

Agar is a hydrocolloid that can be extracted from certain red algae. They are present in plant cell walls, facilitating their flexibility and mobility to facilitate adaptation in different marine environments. Agar is a mixture of polysaccharides, the basic monomer of which is galactose. The degree of sulfation of these polysaccharides is very different but less than that of carrageenan. Agar can be divided into two main components: agarose and agar gel. Agarose is the gelling component while agarose has a very low gelling ability. Agar is widely used. Bacterial agar has been derived from red algae belonging to the genus Gelidium since the discovery of agar plates, which allowed researchers to isolate tuberculosis, cholera, and other pathogenic bacteria. This type of agar is particularly sought after by research institutions, where it is used as a medium for microbiological and molecular biology techniques (agarose gels). In the pharmaceutical industry, agar has long been used as a laxative. In the food sector, it is also used in the canning of meat, fish, and poultry， as well as in cosmetics, and dentistry fields.

Our Services

CD BioSciences produced a wide range of high-quality agars in the fields of microbiology, food, and molecular biology driven by specialization, extensive knowledge of agars, the careful selection and handling of algae, and controlled production processes. Our services are listed as follows, but are not limited to:

• Industrial agar production
• Bacteriological grade agar production
• Food grade agar production
• Natural agar production
• Agar-agar gum production
• Agarose production
• Measuring gel strength

Key Benefits of Our Agar

• Neutral PH
  The agars we produced have a neutral pH and form gels in solution only through hydrogen bonding.
• Unique hysteresis
  The wide 50ºC difference between gel temperature and melting point makes agar versatile in both liquid and gel form up to 90ºC.
• Vegetable origin
  Our agars are produced in an animal-free and ecologically sustainable process.
• Natural extract
  Agar is a natural seaweed extract, and most of the agar we produced is obtained from a variety of red algae.
• Highest gelling power
  Less than 5 grams of agar is required to form a solid gel, which is 6 times less than gelatin.
• Reversible gels
  The excellent stability of our agars makes them suitable for reversible gelation over a wide temperature range.
