【発明の属する技術分野】
本発明は、采藻塩ならびにその製造方法および製造装置に係り、特に野菜ならびに稲科植物、又はその全草、および海藻、海草の全部か、根、茎、葉、花、実のエキスを含有する采藻塩ならびに製造方法および製造装置に関するものである。

【従来の技術】
近年、日本人の食生活において、熱量の過剰摂取、特に動物脂肪からのそれが問題視されるなかで、日本型食生活の弱点として塩分の摂り過ぎが言われてきた。熱量の過剰摂取が、現代人の成人病、すなわち肥満、糖尿病、高脂血症等の生活習慣病の発症を促すとして、警戒されている。その中で、高血圧を引き起こす主原因として、塩分の摂り過ぎによる知見が浸透し、塩は悪玉として扱われ、減塩運動が盛んとなった。ところが、この一律減塩の運動に疑問を投げかける学術データも多くでている。すなわち、人体の塩分に対する反応は、それが如実に出るタイプと全く左右されないタイプがあり、高血圧の予防と治療にも根本的な見直しが必要となった。又、塩のナトリウムイオンよりもむしろクロル（塩素）イオンが高血圧を引き起こす要因となっているのではないかという知見、更に、ナトリウムイオンとカリウムイオンのバランスが問題であるのではないかという知見が立証されてきており、消費者の健康志向や自然志向に伴って、ミネラル分を十分に含んだ自然塩の需要が増加している。一方、塩は古今東西を問わず、人間の食文化に欠かせないものであり、料理のふくよかな味は素材の味を引き立たせるための調味料として極めて重要な位置を占めている。より風味のあるおいしい塩を求めているとき、純度を高くすればするほど、単一の風味になり、味に幅がでないことから、イオン交換樹脂法で作った専売塩に代わって自然塩と称される、海水を濃縮・乾燥して製塩した塩が見直されてきた。これら自然塩に野菜や有益植物および海藻・海草のエキス抽出物を添加混入させることにより、塩の持つ塩蔵という保存能力に加え、野菜や有益植物および海藻・海草が保有する防腐保存能力を合わせ持たせることで、従来、塩蔵に必要とした塩量の加減を図ることに加え、香りや香辛等の嗜好性と、呈味性を一つに集約できる。このように、野菜や有益植物および海藻・海草のエキス抽出物を添加混入した自然塩は、食用として他の食品の旨みを引き出すとともにまろやかさ等を与えるために用いられるのに加え、神経痛や疲労回復、皮膚炎等の治療等の外用剤としても用いられ、漢方食塩、健康食塩、美容食塩などとして有用である。従来の方法によれば、この自然塩の製造方法としては、太陽熱で海水中の水分を蒸発させて作った天然の塩を、一度水に溶かし１３０℃〜１９０℃の高い温度で５時間から１３時間加熱して作る方法が知られている。これらの方法では、加熱するため大きなエネルギーおよび装置が必要であり、又、塩の成分の偏り、マグネシウム、カルシウムおよびカリウムといった苦り成分が取り除かれ自然でなくなるといった問題が生じ、いずれも効率よく生産性に富んだ製塩方法とはいえなかった。一方、野菜や有益植物および海藻・海草のエキス抽出物を添加混入した自然塩を作るには、まず、野菜や有益植物および海藻・海草のエキス抽出物を製造した上で、かん水にこれらエキス抽出物を散布、塗布、および浸漬等の方法で接触させて、野菜や有益植物および海藻・海草のエキス抽出物を添加混入した自然塩を製造するという煩雑さを伴っていた。更に、添加するエキス抽出物が均一に混入して析出することが出来るかどうか、又、被エキス抽出物由来の不純物としての塵埃を除去できるかどうか等の問題を抱えていた。

【０００７】
本発明の中で、▲２▼かん水生成工程で製造されるかん水に遠赤外線放射セラミックスを浸漬した後、被エキス抽出物としての前記采藻を浸漬して采藻エキス含有かん水を生成させる工程において、かん水の温度は２０〜８０℃、好ましくは４０〜６０℃、より好ましくは５０〜６０℃に加熱されるがよく、又、かん水生成工程で製造されるかん水の塩分濃度は１２％〜２８％、好ましくは１５％〜２５％、より好ましくは１８〜２２％であるがよい。かん水生成工程で製造されるかん水に浸漬される前の、前記被エキス抽出物の前処理方法としては、原材料としての被エキス抽出物の性状を損なうことなく十分乾燥（例えば遠赤外線乾燥、マイクロ波乾燥等）させた後、そのまま直接浸漬するかおよび／又は細分化するがよい。このよう前処理された被エキス抽出物を、上記温度および塩分濃度のかん水に漬け込み采藻エキス入りかん水を生成するが、その際、被エキス抽出物が遠赤外線放射セラミックスとともにかん水に浸漬されているが好ましい。
ここで用いられる遠赤外線放射セラミックスとしては、アルミナ系、ジルコニア系、チタン酸アルミニウム系、窒素珪素系、炭化珪素系等の種々の材質が用いられ、これらの材質を板状、球状、棒状、筒状等に形成したもの、金属製やセラミックス製等で形成された基板上に膜状に形成したもの等を用いることができる。この遠赤外線放射セラミックスを浸漬させて加熱することにより、以下のような作用が得られる。

[Prior art]
In recent years, excessive intake of heat, especially from animal fats, has been considered a problem in Japanese diets, and it has been said that excessive intake of salt is a weak point of Japanese diets. Excessive intake of heat is wary of promoting the onset of modern adult diseases such as obesity, diabetes, and hyperlipidemia. Among them, as the main cause of hypertension, knowledge from excessive intake of salt penetrated, salt was treated as bad, and salt-reducing exercise became popular. However, there is a lot of academic data that raises questions about this uniform salt reduction movement. In other words, the response of the human body to salt has a type that does not depend on the type at which it actually appears, and a fundamental review is also required for the prevention and treatment of hypertension. In addition, the knowledge that chlor (chlorine) ions rather than the sodium ions in the salt may cause hypertension, and the knowledge that the balance between sodium ions and potassium ions is a problem. It has been proved that the demand for natural salt containing a sufficient amount of minerals is increasing along with the health and nature orientation of consumers. On the other hand, salt is indispensable for human food culture regardless of east and west, and the rich taste of cooking occupies an extremely important position as a seasoning to enhance the taste of the ingredients. When looking for a more delicious salt, the higher the purity, the more it will have a single flavor and the breadth of the taste. The salt made by concentrating and drying seawater has been reconsidered. By adding these natural salts to vegetables, beneficial plants and seaweed / seaweed extract extracts, in addition to the salt preservation ability of the salt, it also has the preservative preservation ability possessed by vegetables, beneficial plants, seaweed and seaweed. In addition to trying to adjust the amount of salt conventionally required for salting, it is possible to combine tastes such as aroma and spice and taste. In this way, natural salt added with vegetable, beneficial plant and seaweed / seaweed extract extracts is used to extract the umami of other foods and provide mellowness, as well as neuralgia and fatigue. It is also used as an external preparation for the treatment of recovery, dermatitis, etc., and is useful as a Kampo salt, a healthy salt, a cosmetic salt and the like. According to the conventional method, the natural salt is produced by dissolving a natural salt produced by evaporating water in seawater with solar heat once in water and at a high temperature of 130 ° C. to 190 ° C. for 5 hours to 13 hours. A method of making by heating for a time is known. These methods require a large amount of energy and equipment for heating, and also cause problems such as uneven salt components and removal of bitter components such as magnesium, calcium and potassium, which are not natural. It could not be said to be a salt production method rich in nature. On the other hand, in order to make natural salt mixed with vegetable, beneficial plant and seaweed / seaweed extract extract, first, extract the vegetable, beneficial plant and seaweed / seaweed extract, and extract these extracts into brine. It was accompanied by the trouble of producing a natural salt added with and mixed with an extract extract of vegetables, beneficial plants and seaweed / seaweed by contacting the objects with methods such as spraying, coating, and dipping. Furthermore, there are problems such as whether or not the extract to be added can be uniformly mixed and deposited, and whether or not dust as an impurity derived from the extract to be extracted can be removed.

The salinity of the brine produced in the brine production step is 12% to 28%. , Preferably 15% to 25%, more preferably 18 to 22%. As a pretreatment method of the extract to be extracted before being immersed in the brine produced in the brine production step, the extract is sufficiently dried without impairing the properties of the extract as a raw material (for example, far-infrared drying, microwave After drying, etc., it may be immersed directly and / or subdivided. The extract to be extracted which has been pretreated in this manner is immersed in brine having the above temperature and salinity to produce brine containing the diatom extract. At that time, the extract to be extracted is immersed in brine with far-infrared radiation ceramics. Is preferred.
Various materials such as alumina, zirconia, aluminum titanate, silicon nitride, silicon carbide, etc. are used as the far infrared radiation ceramics used here, and these materials are plate-like, spherical, rod-like, tube-like. For example, a film formed on a substrate formed of metal, ceramics, or the like can be used. By immersing this far infrared radiation ceramic and heating it, the following effects can be obtained.

An extract-containing diatom salt containing useful trace components is obtained.
(3) Since supersaturated concentrated seawater is produced by evaporating a portion of the water content of the brine containing the diatom extract, there is little adhesion of scale to the evaporation device, there is little decrease in heat transfer speed, and excellent maintainability. Losses that are easily volatilized in brine containing algae extract can be minimized.
[0009]
In the present invention, (4) the supersaturated seawater containing the diatom extract is subjected to solid-liquid separation by centrifugation and filter press filtration, etc., dehydrated from the supersaturated seawater containing the diatom extract, and further heated with far infrared radiation ceramics. Since the dehydrated salt is dried by microwave heating or the like and has a drying step of collecting it as a diatom salt, the following effects are obtained.

Wakame foliate was used as the extract. As a pretreatment, the wakame leaf portion to be used was sufficiently washed with water, sterilized and disinfected, and then finely cut. Subsequently, 700 liters of raw seawater was boiled and concentrated to produce 100 liters of brine with a salt concentration of 21%. The obtained brackish water is immersed in a far-infrared radiation ceramic plate and heated to 60 ° C., and then 10 kg of dried wakame leaf-like portion is dipped and held for 36 hours to extract the extract from the wakame leaf-like portion, 110 liters was obtained. Furthermore, the water of the brackish water containing the seaweed extract was evaporated to produce 84 liters of supersaturated seawater having a salt concentration of 25%. At this time, soft scale components such as Fe ₂ O ₃ and CaSO ₄ precipitated and precipitated as flat crystals in the supersaturated seawater were scraped off and removed. Next, the extract was solid-liquid separated into garlic salt with extract using a filter press and dried with microwaves at a temperature of 70 ° C. to obtain 20 kg of diatom salt with wakame extract. Table 2 shows the results of component analysis of the rapeseed salt obtained.
