Description

本発明の他の目的は、海藻類を原料として、廃棄物の少ない海藻熱処理組成物の製造方法を提供することである。本発明の製造方法により得られた海藻熱処理組成物を使用した、調味料、食品、健康食品を提供することを目的とする。 Another object of the present invention is to provide a method for producing a seaweed heat-treating composition with less waste using seaweed as a raw material. It aims at providing a seasoning, a foodstuff, and a health food using the seaweed heat-treatment composition obtained by the manufacturing method of the present invention.

また、１０５〜２００℃で加熱処理を行う前に、海藻類を、ｐＨ１〜１３の水性媒体中で３０〜１００℃にて加熱すること（以下、「可溶化処理」ともいう。）も好ましい実施態様である。可溶化処理を行うことにより、海藻類が膨潤及び／又は可溶化されるので、このような可溶化処理を加圧加熱処理前に行うことにより、加熱処理溶液が均一化され、再現性の良い海藻高温抽出組成物が得られ、さらに可溶性成分の収率が向上するので好ましい。以下、可溶化処理を行った後、加圧加熱処理を行う実施態様を「二段階加熱処理」ともいうこととする。
海藻類は室温で水性媒体中に溶解しようとしても、完全に溶解しない。加圧加熱処理前に微粉末状にした海藻類を可溶化することにより、加熱処理溶液が均一化され、品質にばらつきの少ない海藻高温抽出組成物を製造することができるので更に好ましい。 In addition, heating the seaweed at 30 to 100 ° C. in an aqueous medium having a pH of 1 to 13 (hereinafter, also referred to as “solubilization treatment”) before performing the heat treatment at 105 to 200 ° C. is also preferable. It is an aspect. Since the seaweed swells and / or is solubilized by performing the solubilization treatment, by performing such a solubilization treatment before the pressure heat treatment, the heat treatment solution is made uniform and reproducible. A seaweed high temperature extraction composition is obtained, and the yield of soluble components is further improved, which is preferable. Hereinafter, the embodiment in which the pressure heat treatment is performed after the solubilization treatment is referred to as “two-stage heat treatment”.
Seaweeds do not dissolve completely when trying to dissolve in an aqueous medium at room temperature. By solubilizing the microalgae seaweeds prior to the pressure heat treatment, the heat treatment solution can be made uniform, and a seaweed high-temperature extract composition with little variation in quality can be produced.

海藻類の高温抽出組成物はその機能が注目されている。特に、本発明の製造方法では、海藻類を加水分解反応を伴う加熱処理をするため、海藻類に含まれる多糖類が少糖化及び／又はオリゴ糖化し、さらにタンパク質をオリゴペプチド化、またはオリゴペプチドからさらにアミノ酸まで加水分解すると考えられる。本発明により得られた海藻高温抽出組成物は、抗ガン作用、免疫力増強作用、または血圧降下作用を含む各種の生理機能（生理活性）を有していると期待され、また、増粘性、保湿性やゲル化性等のような物理化学的機能の向上に寄与するものである。本発明により得られた海藻高温抽出組成物は、上述の用途には限られず、食品、化粧品、医薬品、繊維加工品等の幅広い製品への用途を有するものである。さらに、原料である海藻類から、高温抽出組成物を得た後の固形分（残渣）は、食物繊維、ペプチド、多糖類等を多く含むことから、家畜飼料及び園芸肥料等に応用して効果的に使用することが可能である。
尚、本発明において、多糖とは多くの単糖から構成される平均分子量が１００，０００を超える糖類を指す。少糖とは、オリゴ糖と同義であって、単糖が複数個結合したものであり、分子量が１００，０００を超えないものを指す。 The high temperature extraction composition of seaweed has attracted attention for its function. In particular, in the production method of the present invention, the seaweed is subjected to a heat treatment accompanied by a hydrolysis reaction. To further amino acids. The seaweed high-temperature extract composition obtained by the present invention is expected to have various physiological functions (physiological activities) including an anti-cancer action, an immunity enhancing action, or a blood pressure lowering action. It contributes to the improvement of physicochemical functions such as moisture retention and gelation. The seaweed high-temperature extract composition obtained according to the present invention is not limited to the above-described uses, and has a wide range of uses such as foods, cosmetics, pharmaceuticals, and processed textiles. Furthermore, the solid content (residue) after obtaining the high-temperature extraction composition from the raw seaweed contains a lot of dietary fiber, peptides, polysaccharides, etc., so it is effective when applied to livestock feed and horticultural fertilizers. Can be used.
In the present invention, the polysaccharide refers to a saccharide having an average molecular weight exceeding 100,000, which is composed of many monosaccharides. The oligosaccharide is synonymous with an oligosaccharide, and is a combination of a plurality of monosaccharides and a molecular weight not exceeding 100,000.
