White Kidney Bean Extract History
Accidental discovery of weight loss in horses
In 1873, when the world economic crisis swept across Europe, the head of the Royal Prussian Horse Breeding Farm in East Prussia, located in the town of Trekna, was in a tight feed situation, and found that the old beans in the warehouse had no worms, which was just enough to be used as fodder for the horses. After feeding them for a while, the horses surprisingly lost weight. It did not occur to me that a query about horse feeding would turn out to be the origin of today's hot topic of the century.
Research on white kidney beans
In 1872, the nutritional value of vegetable proteins was recognized through the work of the German biochemist Karl Heinrich Ritthausen. Yet the problem of weight loss in horses troubled Ritthausen: "Beans do contain protein and are nutritious, so how can they lose weight?" So he began his research on this bean, the white kidney bean.
Preliminary arguments for the principle of action
After a period of research, Ritterhausen found that raw white kidney beans contain ingredients that can make animals hinder digestion, in fact, a class of proteins that will limit the digestive enzymes, and named Legumin. 1872-1884, there are more than 10 around the world around the field of what was considered at the time to be advanced scientific research and discovery. The field of white kidney bean extract research was pioneered.
Successful extraction of amylase-inhibiting protein
In 1893, Dr. Osborne, an American scientist, initially isolated the protein in white kidney beans that inhibits digestion and absorption, and in 1944, Donald E. Bowman discovered that the white kidney bean protein actually caused weight loss in mice through enzyme inhibition, which was published in SCIENCE in 1945. It was not until 1971 that BOWMAN's team actually found a way to isolate the amylase inhibiting protein in the laboratory.
Market applications in various countries
In 2001, Chris Peels' team at the University of California developed a new and stable process, which led to the industrialization of white kidney bean amylase-inhibiting protein in the 1.0 era. 2009, the patented 2.0 version of white kidney bean amylase-inhibiting protein, which is less costly and less restrictive, was put into production in Germany, Japan, and China. 2008, the team of Tianbao Birch Biologicals, with their research results, registered the process of white kidney bean amylase-inhibiting protein extraction in China. In 2008, Tianbao Hua biological team with the research results registered a number of domestic patents in China, including the extraction process of white kidney bean, and began to start the commercial application of α-amylase inhibitor program.
