Cactus moves to meet Western demand for nattokinase
Nattokinase is an enzyme derived from natto, a fermented soy food that is popular in Japan and other parts of Asia. Awareness of the potential is relatively low in the West but is starting to grow as several studies have investigated its antioxidant ability.
“Nattokinase is very attractive in the heart health marketplace as it is both an antioxidant and can have a favourable impact on cholesterol,” said Carol Cheow, general manager of Cactus Botanicals.
The company says its white powdered nattokinase can be mixed with dextrin or other carbohydrates for use in capsules and tablets. It is available in two versions, one with an activity of 12000 fibrin units per gram (fu/g), and one of 20,000fu/g.
Cheow told NutraIngredients-USA.com that the company has recently developed the technology to extract nattokinase from natto with stable quality.
Natto, from which the enzyme is derived, is made by fermenting boiled soybeans with bacillus natto. Cactus Botanic is producing it in China.
Research
In support of its new ingredient, Cactus Botanics cites a study published in the Journal of Agricultural and Food Chemistry in 2002, which looked at the effect of water-soluble natto in inhibiting LDL cholesterol oxidation in rats.
Other recent studies include research from a Taiwanese team, published in Nutrition Research last year, which indicated that Nattokinase may reduce levels of compounds linked to blood clotting, and cut the risk of heart disease in people at-risk of the disease.
Another team from Taiwan also reported in the Journal of Agricultural and Food Chemistry that a lab study suggested nattokinase may prevent the build up of amyloid plaques, linked to Alzheimer’s, in the brain.
Marketplace
Cactus is not alone in recognising the potential of nattokinase in the US. Other suppliers in the marketplace include Japan Bio Science Laboratory-USA, Enzyme USA and Amano Enzyme USA.
