CCTV on the "mystery of natto identity," a series of reports, make this tiny little beans become Mont-business after the food industry and a hot spot of the eye. About natto, consumer doubts, in the end what is natto? how natto product? natto and nattokinase nattokinase? are there any efficacy? what selection of natto products more suited to?
These seemingly simple problem is not easy to get to understand that capacity "natto mysteries" of reports, for example, Japan Mr. expert shall see ocean line is found, nattokinase instead of natto, he has been in the interview process are designed for nattokinase views, but the host is always mentioned natto products, such as "experimental proof shall be provided see Corp., products in natto Thrombolysis, does have a certain effect, patients taking the illness has certain advantages, but at present in our countries, sales of natto product prevailing exaggerated effects, false propaganda, and so on, makes this a new kind of health food into a chaotic misunderstandings." 这里面至少有三个概念不清晰:纳豆、纳豆激酶和保健食品。
让我们看看如何更清晰地分类纳豆产品,他们都有什么特点,会有些什么可能的作用,适应什么样的人群吧。
目前市场的纳豆类产品可以分为4种:鲜纳豆、纳豆胶囊、纳豆配伍胶囊和纳豆激酶胶囊。
一、鲜纳豆
超市里常见的装在精美小盒中淡褐色搅拌可以拉出长长粘丝并发出独特香味的食品就是鲜纳豆,这是真正的纳豆,纳豆在室温下的货架期很短,所以,不得不将其放在冷冻条件下保鲜。
在须见先生发现纳豆激酶之前,纳豆已经有上千年的食用历史了,人们喜欢把它作为佐餐佳肴,相信并不只是因为它独特的味道和含有的纳豆激酶。 从这一点来讲,将须见先生称为“纳豆之父”其实并不是很确切。
2002年,卫生部对中国食品发酵工业研究院经北京市卫生局提出的《关于纳豆作为普通食品的请示》给以批复(卫法监发[2002]308号):“以枯草芽孢杆菌发酵生产的纳豆应按普通食品进行管理”。 自此之后,纳豆在国内才被允许作为普通食品生产和销售。
纳豆是大豆蒸煮后,接种纳豆菌发酵而成,其营养成份等于并高于大豆。 尽管是“普通食品”,新鲜的纳豆中至少有三类对人体有益的东西:
1、纳豆菌
纳豆菌是一种普通的枯草芽孢杆菌,也是亚洲人喜欢的一种益生菌,鲜纳豆中这种菌的含量可以达到每克1亿个,按每次食用50克纳豆计(每小盒),总量可以达到50亿个,足以产生明显的肠道整理作用。 而一条健康的肠道可以给人体带来诸如提高免疫力、改善睡眠、排毒养颜,降低血脂、促进营养吸收等好处,益生菌的这些优点早已被日本人演绎的淋漓尽致了。
2、功效成份
鲜纳豆中含有大豆中原有的以及经发酵产生的多种营养和生理活性物质,如大豆低聚糖、大豆卵磷脂、皂甙、异黄酮、多肽、谷胱甘肽、吡啶二羧酸、超氧化物岐化酶、维生素K2、维生素E、多种维生素和矿物质等。 这些功效成份的作用几乎所有关注健康的人都耳熟能详,他们在50克纳豆中的含量足够高了,日本人把纳豆列入长寿食品,相信这些功效成份发挥了最重要的作用。
3、纳豆激酶
纳豆菌在发酵过程中产生的一种小分子的蛋白酶。 30年前,须见先生偶然发现这种酶具有体外溶解人工血栓的作用,与尿激酶Urokinase、蚓激酶Lumbrokinase的作用类似,称其为Nattokinase,Natto指纳豆,kinase是激酶,加起来译为纳豆激酶。 Now found this enzyme can direct role in thrombosis, rather like the Urokinase plasminogen activation and thus play a fibrinolytic therapy. From this perspective, this enzyme called natto enzyme Nattoase or natto protease Nattoprotease more precise.
Through our sample analysis and related data, normal fermented soybeans in nattokinase content about 40FU/g, at present, China's production of soybeans and other national production of soybeans does not exist quality differences, 50 in Faulkner's bean nattokinase total quantity up to 2000 FU, and the dosage and number of documents recommended nattokinase optimum intake per day.
Longitudinal described on, natto, a comprehensive balance of nutrients to supplement nutrients in comprehensive, adhere to the more favourable long-term consumption for regulating gastrointestinal, full body care, hypolipidemic Thrombolysis is sure to have an effect. However, soybeans and soybean, etc, like in the purine foods hanpiao gout patients should use according to their own specific circumstances.
Second, natto capsules
The natto-frozen, by freeze drying at low temperature and low temperature, while enriching strengthen natto metabolism effect substance, made into capsules. As a result of the advanced processing technology, natto capsule almost entirely preserved the fresh natto activity effectiveness of ingredients, including the activity of Bacillus natto, enzymes and vitamins, which, nattokinase content can improve the 3 to 4 times. The advantages of natto capsule is easy to carry, easy to use quantitative timing, is no longer fresh natto product cold chain sales limited.
Natto Capsule could be a normal food, or you can apply for health food products. At present, China has ratified 5 natto related capsules health food, one of the most industrialized production of early input into the yanjing brand natto capsule (
Beijing yanjing zhongfa biotechnology co., Ltd., the country food-word G20040604) and Kim Kang natto capsule (Shanghai NOK Jinke biotechnology country key word G20100038) belongs to this class of product, its natto health claims that are immune and enhance immunity.
3. compatibility of capsule natto
To natto lyophilized powder and other medicinal and edible ingredients combined with steel capsule, usually in the form of health food. This capsule products primarily via the efficacy of other raw material ingredients to enhance the efficacy of natto, such as lipid function, etc. At present, China's approval of such health food has 3: best brand natto capsule (Beijing Bah technology development co., Ltd., food-word (2003) 0323), the primary efficacy contain vitamin E and linoleic acid, health claims for lipid; Paul brand natto monascus capsule (with Paul biotechnology in Beijing, the country food-word G20100591), the main raw material is the main red yeast rice powder, breadcrumb trail content as lovastatin, health claims for supplementary hypolipidemic; more Foundation media brand natto Fuling capsule (Hubei mackeson biotechnology co., Ltd., the country food-word G20080679), this kind of product compatibility of materials more, kudzu, alisma orientalis, Fuling, cassia, starch, its efficacy contain flavonoids, health claims for supplementary hypolipidemic;
Fourth, nattokinase capsules
This kind of products and traditional solid fermented soybeans have no contact. Usually adopts the submerged fermentation, large-scale cultivation of Bacillus subtilis natto, and broth through complex of purification technology, preparation of the component single nattokinase products. This product has high kinase activity, can be as high as per gram 20000FU, equivalent to 500 g of fresh nattokinase nattokinase in total. Because of high purity, natto of other active substances, there is no will, like natto, oligosaccharides, soya lecithin, saponins, isoflavones, peptides, and so on, of course, does not contain the vitamin K2 controversy and purine.
You can use this material into each capsule preparation containing 1000FU nattokinase capsule products, sooner or later the grain, the only effect is Thrombolysis, audience is very clear, natto other health feature ceased to exist, such as adjusting the stomach, enhance immunity, etc. Therefore, for health benefits kin, this product is not the best choice.
At present, yet enterprises launched this product, the product attribute is still not clear. Nattokinase capsules already does not have the characteristics of natto, cannot be called a common food, but also not easy to declare health food products, because Thrombolysis function already belongs to the category of drugs, that is a special dietary products seems to be very reluctantly, like lumbrokinase as drugs into the market for too long. Therefore, despite the high activity of nattokinase capsule products for prevention of cardiovascular disease may be more of a role, but their access to markets also face product positioning and administrative issues.
