It's important to note that the commercial extraction and application of guar gum as a standardized additive was a collective effort involving researchers, industries, and farmers. The exact individual or organization responsible for its initial commercial development is not as widely documented, but the broader development and popularization of guar gum as a commercial product can be attributed to the combined efforts of various stakeholders in the mid-20th century.

Gum Arabic: Gum arabic, also known as acacia gum, is a natural gum made from the hardened sap of various species of the acacia tree. It has been used for thousands of years in various cultures, primarily in the African Sahel region, which includes parts of Sudan, Senegal, and Somalia.

The use of gum arabic dates back to ancient civilizations. The ancient Egyptians, for instance, used it in the mummification process, in cosmetics, and as an adhesive for papyrus. It was also used in traditional African and Middle Eastern cultures for various purposes, including as a food stabilizer, in medicine, and in arts and crafts.

Given its long history of use, gum arabic wasn't "developed" in the modern sense by a specific individual or company. Instead, its properties and applications were recognized and utilized by ancient cultures. However, its trade became significant, especially in the Middle Ages, when it was exported to Europe for use in various industries, including the food and art sectors.

In summary, while gum arabic has been used for millennia by various cultures, its commercial trade and broader applications expanded significantly in more recent centuries.

Carrageenan: As an example, carrageenan is a natural substance derived from red seaweeds, and it has been used for centuries, especially in coastal regions where these seaweeds are abundant. The use of carrageenan as a food thickener can be traced back to Ireland in the 400s AD, where it was known as "Irish moss." Coastal communities would boil the seaweed to extract the carrageenan and use it as a gelatinous substance in foods.

While the traditional use of carrageenan dates back centuries, its commercial extraction and recognition as a food additive began in the 20th century. The term "carrageenan" comes from the Irish word "carragáin," which means "little rock," likely referring to the rocky habitats where the red seaweed grows.

So, while carrageenan as a substance wasn't "discovered" in the traditional sense, its properties and potential applications were researched and developed in the modern era.

Tara Gum: Tara gum is a natural polysaccharide derived from the seeds of the tara tree (Caesalpinia spinosa), which is native to South America. The use of tara seeds for various purposes can be traced back to ancient indigenous cultures in the Andean region.

The commercial development and extraction process for tara gum as a food additive and thickening agent began in the mid-20th century. While the exact individual or organization responsible for its initial commercial development is not as widely documented as some other gums, the increasing demand for natural thickeners and stabilizers in the food industry during the 20th century led to the exploration and commercialization of various plant-based gums, including tara gum.

It's worth noting that while the commercial extraction and application of tara gum as a standardized food additive began in the 20th century, the tara tree and its seeds have been utilized by local populations in South America for much longer.

Xanthan Gum: Xanthan gum was discovered by a team of researchers at the United States Department of Agriculture (USDA) in the 1960s. The team was led by Allene Rosalind Jeanes. They were studying the bacterium Xanthomonas campestris, which produces a polysaccharide during fermentation that was later named xanthan gum. This polysaccharide was found to have unique properties that made it valuable as a thickening and stabilizing agent in various industries, especially the food industry. As a result of their research, xanthan gum was commercialized and is now widely used in many products.

Pectin: Pectin is a naturally occurring polysaccharide found in the cell walls of plants, especially in fruits. It has been used for centuries in cooking and baking, particularly as a gelling agent for jams and jellies.

The use of pectin in food preparation dates back to ancient times, and its gelling properties were likely discovered through traditional cooking practices. For instance, boiling certain fruits, like apples or quinces, would naturally release pectin and cause the mixture to gel.

The scientific understanding and extraction of pectin began in the 19th century. In 1825, Henri Braconnot, a French chemist, isolated and described pectin from plant tissues, making him one of the first to recognize and study pectin as a distinct substance. However, the commercial production and application of pectin as a standardized food additive began in the early 20th century.

In summary, while pectin itself is a natural substance that has been used for centuries, its scientific understanding and commercial development can be attributed to researchers in the 19th and 20th centuries.

Gellan Gum: Gellan gum is a polysaccharide produced by the bacterium Sphingomonas elodea (formerly known as Pseudomonas elodea). The development and commercialization of gellan gum can be attributed to the American multinational corporation CP Kelco (and its predecessor companies), which undertook extensive research on this microbial polysaccharide in the 1970s and 1980s.

CP Kelco introduced gellan gum to the market under the brand name "Gelrite" or "Kelcogel." The gum has since become a valuable additive in the food, pharmaceutical, and other industries due to its unique gelling, stabilizing, and thickening properties.

So, while the bacterium naturally produces gellan gum, its development for commercial applications and its introduction to the market was spearheaded by CP Kelco.

Thanks to the innovative work of these and other researchers, hydrocolloids have become an essential component in a wide variety of applications, from food processing to pharmaceuticals and beyond.
