Description

Technical Field

[0001] The invention relates to the technical field of low-sodium potassium-rich salts, in particular to a taurine low-sodium potassium-rich salt and a preparation method thereof. Background Art

[0002] At present, there is evidence from evidence-based medicine that low sodium salt (containing 60% to 80% potassium chloride plus 30% to 40%) can reduce blood pressure and the incidence of stroke. Therefore, vigorously promoting the use of low sodium salt is the most effective group prevention measure to reduce cardiovascular and cerebrovascular diseases. In addition, cancer is also the main disease that threatens the lives of Chinese residents. Therefore, how to add foods that can prevent cancer to salt is also an important direction for the research and development of the salt industry.

[0003] Ordinary table salt contains 100% sodium chloride. Long-term consumption increases the risk of hypertension, coronary heart disease and stroke, seriously increases the social disease burden, and excessive sodium salt intake even leads to cancer. Recent studies have found that in mice, monkeys and humans, the concentration of circulating taurine decreases with age. Taurine supplementation reverses this decline and increases the health life span (healthy life period) and life span of mice and monkeys. Mechanistically, taurine can reduce cell aging, prevent telomerase deficiency, inhibit mitochondrial dysfunction, reduce DNA damage, and reduce inflammation. Taurine deficiency may be a driving factor in aging. In addition, taurine can inhibit ferroptosis mediated by crosstalk between tumor cells and tumor-associated macrophages in prostate cancer, and taurine is an important driver of CD8+T cell immune response, which can be used as a potential therapeutic agent for cancer patients. In addition, studies have found that reduced taurine levels are closely associated with the development of osteoporosis and sarcopenia within four years. Other studies have found that taurine has a time-dependent improvement effect on γ-irradiation-induced brain damage in rats. Based on this, the present invention provides a taurine low-sodium potassium-rich salt and a preparation method, which can achieve the effects of aging, cancer prevention, and osteoporosis prevention at the group level through a daily low-sodium salt diet, as well as improve the prevalence of chronic diseases such as hypertension and coronary heart disease. Summary of the invention

[0004] The present invention aims to provide a taurine low-sodium potassium-rich salt and a preparation method thereof, wherein taurine having the effects of anti-aging, anti-cancer, anti-radiation and prevention of osteoporosis is added to achieve the purpose of anti-aging, prevention of hypertension, coronary heart disease and stroke, and obtains a taurine low-sodium potassium-rich salt having multiple effects of anti-aging, anti-cancer, anti-radiation and prevention of osteoporosis.
