The invention provides activated carbon for use in an aroma fixative, an aroma fixative for foods, and a method of slowly releasing food aromas. The aroma fixative includes an activated carbon granule having a particle size of 300 to 400 mesh and a volatile perfume molecule is bound to the activated carbon granule. The aroma fixative is added to a food product at 1PPM to 50PPM by weight of the food product. Because the volatile perfume molecule is bound to the activated carbon granule by van der Waals forces, the volatile perfume molecule is slowly released from the food product. The aroma of the food product can thereby be preserved for a long time and the food product when being put into the mouth would impart a natural and enriched aroma.本發明係有關於一種活性碳用於食材定香劑之用途及食材定香劑、食材定香緩釋之方法,所述的食材定香劑包括有一尺寸為300mesh至400mesh的活性碳粉末,以及在前述活性碳粉末上吸附有一揮發性香料分子。將前述食材定香劑添加於一食材中,且添加比例介於1PPM至50PPM之間,因為前述揮發性香料分子利用凡德瓦爾力吸附在前述活性碳粉末上,藉此可緩慢由前述食材中揮發出前述揮發性香料分子,長時間保留前述食材的香氣,使前述食材入口後,其氣味天然而厚實。(1)‧‧‧活性碳粉末(2)‧‧‧揮發性香料分子(3)‧‧‧水
