Description

Technical Field

[0001] The present disclosure relates to a sugar-coated product that contains an edible tar pigment in the sugar-coated part but can suppress discoloration due to light exposure.

Background Art

[0002] A sugar-coated product is a product in which the surface of a core material (contents) is coated with a sugar-coated part in order to mask the unpleasant taste and odor of the core material or to protect the components contained in the core material from moisture, light, etc. Sugar-coated products are widely used in the fields of pharmaceuticals and foods because they are easy to take and have excellent appearance.

[0003] Conventionally, in order to beautify the appearance of sugar-coated products and enhance their commercial value, sugar-coated products have been colored by blending a coloring agent in the sugar-coated part. For example, Patent Document 1 describes that a colored sugar-coated tablet in which the outermost layer of the sugar-coated layer is composed of sugar alcohols with low solubility, saccharides with high solubility, and a coloring agent can achieve stabilization of a drug that decomposes in high moisture, has masking properties and moisture-proof properties, and can make the surface clean. Further, Patent Document 2 describes that a hard sugar-coated tablet with good color tone and texture can be obtained by applying a sugar coating to a core material containing 10.0 to 50.0% by weight of crystalline maltitol and 50.0 to 90.0% by weight of a crystalline powder which is one or a mixture of two or more selected from the group consisting of xylitol, erythritol, mannitol, and sorbitol with a maltitol solution containing a coloring agent.

[0040] 2. Evaluation of the photo-stability of sugar-coated tablets The 252 obtained coated tablets were placed in a white 120-ml plastic bottle and sealed, and left standing in a room where direct sunlight exposure was possible for 5 days. Before and after the sunlight exposure, the coated tablets were photographed using a desktop two-dimensional colorimeter PPLB-400 (Papalabo Co., Ltd.), and the xy3D matching degree (color distribution matching degree) before and after the sunlight exposure was determined.

[0041] The results are shown in Fig. 1. When the sugar-coated part contained edible tar pigments (Red No. 3, Red No. 102, and Yellow No. 5) and did not contain starch, fading occurred after sunlight exposure, and the xy3D consistency was also low. Also, even when the sugar-coated part contained edible tar pigments and starch, when titanium oxide was included, fading after sunlight exposure was promoted, and the xy3D consistency was even lower. In contrast, when the sugar-coated part contained edible tar pigments and starch and did not contain titanium oxide, fading after sunlight exposure could be suppressed, and the xy3D consistency was high.
