An liquid oil and fat ingredient or others are carried by pores of a porous carrier composed of porous starch grain obtained by reacting an enzyme having raw starch digestive activity onto the starch. Starch being used as porous carrier, the powder preparation according to the present invention is not harmful to the human body, it can be supplied continuously in great volume, manufactured cheaply without difficult processing and moreover, being completely biodegradable which does not incur any environmental problems, it can be used largely in various industrial fields. A liquid fat component or the like is carried in cavities of a porous carrier composed of porous starch powder which is obtained by treating starch with an enzyme having a raw starch decomposing capability. As a powdery pharmaceutical preparation of the invention uses starch as a porous carrier, it is harmless to the human body, capable of stably supplying in a large amount, and low in production cost, and neither needs any complicated processing nor causes environmental problems owing to its perfect biodegradability, so that it can be used widely in various industrial fields.
