A food particle structure made of QRT, comprising: an extract core, the material source of the extract core is a plant extract or an animal extract； and an active protective layer coated on the outside of the core of the extract, In order to prevent the external environment from affecting the activity of the extract core, the storage stability of the food particle structure made by QRT and the absorption rate by the human body are improved.一種利用QRT製成之食品微粒結構，包括：一萃取物核心，該萃取物核心之材料來源係由植物萃取物或動物萃取物；以及一活性保護層，包覆於該萃取物核心之外部，藉以防止外在環境影響萃取物核心之活性，以提高該利用QRT製成之食品微粒結構的儲存安定性以及被人體吸收率。
