When the powder is used, porous granules can be obtained, which are excellent in solubility and substance adsorption ability. When a raw material having a solubility of more than 100, for example, sucrose, is used, it is difficult to dry under reduced pressure because it foams, and the solubility of the raw material is high, so that the desired porous granules cannot be obtained. If the solubility in 100 mL of water at 20 ° C. is at most 100 g, lactose, glucose, sugar alcohol, salt, other powders other than lactose, glucose, sugar alcohol, salt, amino acid or amino acid salt can be mixed, but lactose, glucose, sugar alcohol, salt. , At least one selected from the group consisting of amino acids and amino acid salts is preferably at least 80%, more preferably at least 90% by weight, still more preferably at least 95% by weight, particularly preferably when the total powder is 100% by weight.

実施例１と同様の工程で、ゼラチン及び水の量を変えて比較例２−１及び２−２として、実施し、得られた多孔質顆粒の溶解性試験を実施した。原料重量、溶液中のゼラチン濃度、固形分（ラクトースとゼラチンとの合計）に占めるゼラチン割合及び溶解性を表３にまとめた。尚、比較例２−１は、冷却後に細切できるだけのゲル強度とならず、減圧乾燥工程に進めなかった。[Comparative Example 2]
In the same step as in Example 1, the amounts of gelatin and water were changed to carry out as Comparative Examples 2-1 and 2-2, and the solubility test of the obtained porous granules was carried out. Table 3 summarizes the weight of the raw material, the concentration of gelatin in the solution, the ratio of gelatin to the solid content (total of lactose and gelatin), and the solubility. In Comparative Example 2-1, the gel strength was not sufficient to be shredded after cooling, and the process could not proceed to the vacuum drying step.
（溶解性試験）
各顆粒０．５ｇを７０℃の１００ｍＬ温水に加えてさじで２秒間混ぜた、直後又は１分後の溶液状態を評価した。
顆粒が溶解する場合は、まず、顆粒が水を吸収して崩壊することによって白濁し、次に、完全に溶解してクリアになった。一方、溶解しない場合は、顆粒が水を吸収しないため崩壊せず、上部で凝集したため、溶解性の評価は、○：「クリアな溶液」、△：「顆粒が崩壊して白濁」、×：「上部で凝集」とした。(Solubility test)
0.5 g of each granule was added to 100 mL warm water at 70 ° C. and mixed with a spoon for 2 seconds, and the solution state immediately after or 1 minute later was evaluated.
When the granules were dissolved, they first became cloudy by absorbing water and disintegrating, and then completely dissolved and cleared. On the other hand, when it does not dissolve, the granules do not disintegrate because they do not absorb water and aggregate at the top. Therefore, the evaluation of solubility is as follows: ○: “Clear solution”, Δ: “Granule disintegrates and becomes cloudy”, ×: It was defined as "aggregation at the top".
比較例２より、ラクトースと混合する溶液中のゼラチン濃度が２％以下であり、固形分に占めるゼラチン割合が２．４％以下の場合は、多孔質顆粒が得られないことが分かった。
また、表３より、溶液中のゼラチン濃度が１６％以上であり、固形分に占めるゼラチン割合が１６．７％以上の場合は、顆粒の溶解性が悪く、本発明の多孔質顆粒は得られないことが分かった。
一方、ラクトースと混合する溶液中のゼラチン濃度が４〜１２％であり、固形分に占めるゼラチン割合が４．８〜１３％の場合は、多孔質顆粒が得られると共に、溶解性にも優れていることが分かった。From Comparative Example 2, it was found that when the gelatin concentration in the solution mixed with lactose was 2% or less and the gelatin ratio in the solid content was 2.4% or less, porous granules could not be obtained.
Further, from Table 3, when the gelatin concentration in the solution is 16% or more and the gelatin ratio in the solid content is 16.7% or more, the solubility of the granules is poor and the porous granules of the present invention can be obtained. It turned out not.
On the other hand, when the gelatin concentration in the solution mixed with lactose is 4 to 12% and the gelatin ratio in the solid content is 4.8 to 13%, porous granules can be obtained and the solubility is excellent. It turned out that there was.
実施例１−１で得られた多孔質顆粒に、ごま油を添加、混合し、油吸着顆粒を得た。油吸着顆粒について、段落［００２０］に従い、「疎充填時のかさ体積（Ｖ０）」と「これ以上のかさ体積変化が生じなくなるまで試料をタップした後の最終かさ体積（Ｖｆ）」を各５回ずつ測定して、圧縮度及びＨａｕｓｎｅｒ比を求め、各平均値を算出した。原料重量、圧縮度、Ｈａｕｓｎｅｒ比及び表１に基づく流動性の尺度を表４にまとめた。 Sesame oil was added to and mixed with the porous granules obtained in Example 1-1 to obtain oil-adsorbed granules. For the oil-adsorbed granules, according to paragraph [0020], "bulk volume (V0) at the time of sparse filling" and "final bulk volume (Vf) after tapping the sample until no further change in bulk volume occurs" are 5 each. The degree of compression and the Hauser ratio were measured each time, and each average value was calculated. Table 4 summarizes the raw material weight, compressibility, Hauser ratio and fluidity measures based on Table 1.
表４より、油吸着顆粒全体を１００重量％として、油溶性物質を４０％吸着させても、極めて良好な流動性を有する顆粒が得られることが分かった。 From Table 4, it was found that even if 40% of the oil-soluble substance was adsorbed with the whole oil-adsorbed granule as 100% by weight, granules having extremely good fluidity could be obtained.
