Refined carrageenan has a 2% maximum for acid-insoluble material and is produced by alcohol precipitation or potassium chloride gel press process. [19] Semi-refined carrageenan has a much higher cellulose content [21] and is produced in a less complex process. Indonesia, the Philippines, and Chile are three main sources of raw material and ...

Differences in carrageenan chemistry, with Hypneaceae species producing kappa-carrageenan and Cystocloniaceae producing lambda-carrageenan, was another reason for their distinction. [5] However, these criteria were questioned and molecular analysis later showed that the two families had similar vegetative and reproductive characters.
Optical chemical structure recognition (OCSR) is the translation of images that depict chemical structure information into machine-readable formats. [1] It addresses the challenge of translating chemical structures from graphical representations into their corresponding chemical formulas.
Astaxanthin / æ s t ə ˈ z æ n θ ɪ n / is a keto-carotenoid within a group of chemical compounds known as carotenoids or terpenes. [3] [4] [5] Astaxanthin is a metabolite of zeaxanthin and canthaxanthin, containing both hydroxyl and ketone functional groups.
Poligeenan is produced by the harsh acid degradation of carrageenan. Carrageenan in solution is processed at low pH (~1.0) and high temperature (90 °C (190 °F)) for up to six hours until the weight-average molecular weight (M w) has been reduced to the range 10,000 – 20,000 daltons (10–20 kDa).
Chondrus crispus—commonly called Irish moss or carrageenan moss (Irish carraigín, "little rock")—is a species of red algae [1] which grows abundantly along the rocky parts of the Atlantic coasts of Europe and North America. In its fresh condition it is soft and cartilaginous, varying in color from a greenish-yellow, through red, to a dark ...
