The present invention relates to a method for homogenizing the solid phase of astaxanthin powder, including: adding a free astaxanthin powder to an edible powder to become a mixed powder, and pre-mixing, and the pre-mixing time is intermediate Between 5 and 15 minutes. The above-mentioned mixed powder is fused by micro powder fusion technology. The mixing parameter is between 20000 to 30000 revolutions per minute, and the action time is between 20 seconds and 40 seconds. After that, let it stand to avoid accumulation of heat. The standing time is between 5 to 15 minutes, and the mixing is repeated at least 3 times to obtain the astaxanthin mixed powder with uniform solid phase.本發明係有關於一種蝦紅素粉固相均勻化之方法，包括：將一游離態蝦紅素粉體添加至一可食用粉體中成為一混合粉體，並進行預混合，預混合時間介於5至15分鐘之間。以微粉融合技術將上述混合粉體進行微粉融合，混合參數為每分鐘介於20000轉至30000轉之間，作用時間介於20秒至40秒之間，之後將其靜置，避免累積熱量，靜置時間介於5至15分鐘之間，並重複至少3次混合，以獲得固相均勻化之蝦紅素混合粉體。
