PROBLEM TO BE SOLVED: To provide a pigment stabilizer derived from starch capable of suppressing fading of a pigment compound without greatly affecting a taste of a food after addition thereof using the starch having safety established as the food and easily available at low cost as a raw material.SOLUTION: The pigment stabilizer is suitable for stabilizing coloring of a pigment mainly derived from a natural product and contains a micro-dispersed starch prepared by carrying out processing of irradiating the starch consisting essentially of waxy corn starch with ultrasonic waves and dispersing the starch as an active ingredient. The pigment stabilizer is a liquid prepared by solubilizing the micro-dispersed starch in water or powder obtained by powdering the micro-dispersed starch.COPYRIGHT: (C)2008,JPO&INPIT【課題】食品としての安全性が確立され安価に調達容易なデンプンを原料として、色素化合物の退色を抑制し、添加後の食品の味に大きな影響を与えないするデンプン由来の色素安定剤を提供する。【解決手段】主に天然物由来の色素の発色安定化に好適な色素安定剤であって、ワキシーコーンスターチを主体としたデンプンに超音波を照射する加工を施して分散した微分散デンプンを有効成分とし、当該微分散デンプンを水溶化した液体、もしくは当該微分散デンプンを粉体として得た色素安定剤である。【選択図】図1
