L-carnitine, its chemical name is 3 hydroxy -4 - three amino butyric acid lactone, and its nutritional value has always been a matter of concern. As early as 1984, the United States FDA clear that L-carnitine is an important food nutrition fortifier.
L-carnitine is the micro-organisms, animals and plants, one of the basic ingredients. Adult tissue contains about 20 grams or so, most of the skeletal muscle, heart muscle, liver, etc., of which the highest levels of the heart muscle. Food and food in meat and dairy foods with a high level to the highest levels of mutton (up to 2100 mg per kg), in levels of plant food is extremely rare, so the possibility of a lack of strict vegetarians more.
Can not only access to food intake of L-carnitine, but also in the body can also be self-synthesis, liver and kidney are the main organs of the synthesis. In general, adults can maintain their normal metabolic requirements for synthesis of L-carnitine, but also often occurs in human L-carnitine deficiency, especially the elderly and infants. Ability to reduce the in vivo synthesis of the elderly, infants can not or difficult synthesis, mainly by breast milk supply, such as large amount of exercise training in athletes, the spirit of the work of a high concentration of population and obesity, heart disease, kidney disease caused by the body, such as L-carnitine the lack of crowd, on its own synthesis and exogenous natural food supply is not enough, need to add, it would be L-carnitine as a nutritional food additive.
L-carnitine is the main physiological functions: ① transport fatty acids into the mitochondria and to engage in B-oxidation, in order to promote the burning fat to provide energy and therefore have a hypolipidemic and improve exercise capacity and the human body, such as the role of weight loss. ② the protection of cells: the excessive amount of acyl-coenzyme A to prevent the exclusion of in vitro cell damage. ③ to prevent the accumulation of lactic acid. Intense exercise a large amount of lactic acid, L-carnitine can reduce lactic acid formation, to improve exercise tolerance. At the same time, it also has the energy to promote the use of substances such as carbohydrates, to increase the number and vitality of the sperm and so on.
L-Carnitine's main production methods: ① extraction: that is, directly from the meat or dairy food to extract, because of their higher cost, the use of less general; ② enzymatic conversion: that is, with the industrialized production of chemical synthesis of racemic carnitine, enzyme treatment and after processing can be high purity L-carnitine: ③ biological fermentation: the existence of many micro-organisms in L-carnitine. Can make use of microbial fermentation, breeding good strains, the production of L-carnitine. This method has industrial production in Switzerland. In addition, there are many other methods. At present, only L-carnitine, Switzerland, Italy, Japan and a few other countries can be produced, mainly by domestic demand, imports, prices of more expensive. Northeast China and other pharmaceutical companies have begun production, Jiangsu Institute of Microbiology enzymatic preparation has been carried out research. .
Slimming food: L-carnitine may be burning excess body fat as energy. It can reduce weight, reduce body fat content, has a role in weight loss and is not a very good diet, not anorexia, not fatigue, weight loss methods do not diarrhea. L-carnitine in the diet as the main components of fitness are very popular food in Europe and the United States, China has also listed a small number of similar products.
Athletes food: L-carnitine to improve the movement power, and enhance exercise endurance and so good. Generally applies to foreign-based health food movement, the current application of L-carnitine after little experiment to prove the security of States is safe. The United States FDA requirements for the ADI value of 20 mg per kg per day for adults, the maximum daily intake of 1200 milliliters per person, outside of a raw material for L-carnitine at 150 U.S. dollars per kilogram.
Developed countries in Europe and the United States, made of L-carnitine in the movement of food, slimming food, infant formula and other food and many types of health food products. And the current small number of such products, and most customers do not know much about it, but because of the efficacy of L-carnitine the role of the good in our country it has a considerable market demand.
