- the ingredients of the syrup of the above recipe were mixed and boiled until the sugar content (Brix) reached 72 degrees.
- 1 g of the curcumin dispersion preparation of Example 5 was added to 29 g of the obtained boiled liquid to prepare a sugar-coated candy syrup.
- 1 g of the syrup was applied to 60 g of spherical hard candy having a diameter of 1.5 cm, and gently dried using a sugar-coated bread to prepare a sugar-coated candy.
- the prepared sugar-cooked candy was uniformly colored in a bright and bright yellow color, with no unevenness of color, both when observed on the surface of one candy and when observed between multiple candy.
- the curcumin-dispersed preparation of Example 5 was stored at 60 ° C.
- a sugar-coated candy was prepared in the same manner as described above. As a result, a brightly yellow, uniformly colored sugar-coated candy was obtained. It was. Moreover, the color tone was the same as the sugar-coated candy prepared using the curcumin dispersion formulation before storage for 1 week at 60 degreeC.
- Production Example 6 Example: Formulation [containing modified gum arabic and various modified starches]
- the formulations of each Example having the respective compositions shown in Table 10 were produced.
- Table 10 shows the grindability, the median diameter of the particles obtained by grinding, and the formulation storage stability.
- no increase in viscosity which is a problem during pulverization in preparation production, was observed, and the pulverization suitability was “good”.
- all the preparations were “excellent” or “good” in storage stability.

アラビアガムは、マメ科アカシア属に属する植物(アカシア:特にAcacia senegal及びAcacia seyal)の幹又は枝から得られる天然滲出物である。アラビアガムは水に高濃度で溶解し、その水溶液は比較的低濃度で、強い乳化力、乳化安定化力、カプセル化力、粘着性、保護コロイド性、及びフィルム形成性を有することから、従来から広く乳化剤、増粘剤、安定剤、結合剤又は皮膜剤として利用されている。

これらの種に属する天然アラビアガムは、構造上の相違に基づいて、異なる分子量、異なる蛋白質分布、及び異なる分子特性を有している。
例えばA.senegal種に属する天然アラビアガムは左旋性を示し、-30前後の比旋光度を有する。これに対して、A.seyal種に属する天然アラビアガムは右旋性を示し、+50前後の比旋光度を有する。また、A.senegal種に属するアラビアガムと比較して、A.seyal種に属するアラビアガムはタンパク質含量(窒素含量)が低く、水溶液にしたときの粘度が低く、かつ糖組成が異なることが知られている。

1.粉砕適性
各実施例、及び比較例の製剤の製造時における粉砕適性は、粉砕された製剤の粘度又は流動性と強く関係する。
すなわち、例えば、粉砕により製剤の粘度が著しく高くなった場合、又は流動性が著しく低下した場合、それ以上の粉砕は困難になる。従って、その指標であることができる、次の排出率(%)に基づいて、製剤の粉砕適性を決定した。
<排出率(%)の決定、及び粉砕適性の判断>
粘度又は流動性の指標である排出率(%)は、次の方法で決定した。
スクリュー管NO.6(直径3cm×高さ6.5cm)に25gの試料を入れ、及び50℃に温度調整する。
これを120°傾け、5秒間に排出された試料質量(g)を測定し、及び排出率(%)を算出する。
当該排出率が50%未満のとき、粉砕適性が不良であると判断し、及び
当該排出率が50%以上のとき、粉砕適性が良であると判断する。
当該方法による排出率のバラツキは極めて小さく、n=3での試験結果例(後記比較例1、比較例3、及び実施例3)は表1に示した通りである。
各実施例、及び比較例の製剤の保存安定性は、製造後の製剤を所定の温度で所定の時間静置した時の外観を肉眼で観察することにより、以下の規準に基づいて4段階で評価した。当該保存安定性試験の開始時には、粒状物は観察されなかった。
<製剤の保存安定性の評価基準>

いずれの製剤においても、製剤製造における粉砕時に問題となる粘度の上昇はみられず、粉砕適性は「良」であった。及び更に、いずれの製剤も、保存安定性が良であった
これらの結果から、改質アラビアガムと加工デンプンの比率として、少なくとも、改質アラビアガム100質量部に対して、加工澱粉6.15~31.78質量部の範囲内の比率において、粉砕適性、及び製剤の保存安定性が共に良いことが確認された。
ダイノミルを用いて、未改質のアラビアガム、及び加工デンプンを含有する、表7に記載の各組成を有する、各実施例の製剤を製造した。
その粉砕適性、粉砕により得られた粒子のメジアン径、及び製剤保存安定性を表7に示した。これらの実施例の製剤のpHは、いずれも3.3~3.6の範囲内であった。
いずれの製剤においても、製剤製造における粉砕時に問題となる粘度の上昇はみられず、粉砕適性は「良」であった。及び更に、いずれの製剤も、保存安定性が「可」であった。
これらの結果から、少なくとも未改質のアラビアガムの添加量が15質量%以下の場合、問題となる粘度上昇は見られず、すなわち、粉砕適性が良いこと、が確認された。
ダイノミルを用いて、ショ糖脂肪酸エステル、及び加工デンプンを含有する、表8に記載の各組成の製剤を製造した。
いずれも、正常に製剤が得られ、粉砕適性は「良」であった。しかし、いずれの製剤も、保存安定性が不良であった。すなわち、アラビアガムの場合とは異なり、加工デンプンと併用した場合でも、保存安定性が不良であった。
実施例5で得られたクルクミン分散製剤を用いて表9の処方で糖衣キャンディーシロップを調製した。
得られた煮詰め液29gに対して、実施例5のクルクミン分散製剤を1g添加し、糖衣キャンディーシロップを調製した。
直径1.5cmの球形ハードキャンディー60gに対して前記シロップを1g掛け、糖衣パンを用いて緩やかに乾燥させて、糖衣キャンディーを調製した。
調製された糖衣キャンディーは、鮮やかな明るい色調の黄色に、1個のキャンディーの表面での観察においても、複数のキャンディー間での観察においても、着色ムラなく均一に着色されていた。
更に、実施例5のクルクミン分散製剤を60℃で1週間保存後、前記と同じように糖衣キャンディーを調製したところ、前記と同様に、鮮やかな明るい黄色で、均一に着色された糖衣キャンディーが得られた。
また、その色調は60℃で1週間保存前のクルクミン分散製剤を用いて調製された糖衣キャンディーと同じであった。
製造例3と同様にして、但し、各種加工デンプンを用いて、表10に記載の各組成を有する、各実施例の製剤を製造した。
その粉砕適性、粉砕により得られた粒子のメジアン径、及び製剤保存安定性を表10に示した。
いずれの製剤においても、製剤製造における粉砕時に問題となる粘度の上昇はみられず、粉砕適性は「良」であった。及び更に、いずれの製剤も、保存安定性が「優」又は「可」であった。
