The present invention relates to a fragrance composition for increasing concentration, a health functional food and cosmetic composition for increasing concentration, including the fragrance composition, and a method for producing a fragrance mixture having a concentration increasing effect, and a fragrance mixture having a concentration increasing effect prepared by the above method. The fragrance composition of the present invention increases the relative beta power spectrum (RB) in the right frontal lobe, right frontal lobe, central frontal lobe, and right occipital lobe, and the RG (relative gamma power spectrum) in the right frontal lobe, central frontal lobe, right occipital lobe, and left occipital lobe. Increasing the relative high beta power spectrum (RHB) in the right frontal lobe, right frontal lobe, medial frontal lobe, medial parietal lobe, and right occipital lobe, and in the right occipital lobe of RSMT (ratio of (SMR-mid beta) to theta power spectrum) Increase in SEF50 (sp in right frontal lobe, right frontal lobe, medial frontal lobe, medial parietal lobe, left temporal lobe and right occipital lobe) increased ectral edge frequency 50%), increased SEF90 (Spectral edge frequency 90%) in the right frontal lobe, medial frontal lobe, and right occipital lobe, and ASEF in the right frontal lobe, right frontal lobe, medial frontal lobe, left temporal lobe, medial parietal lobe, and right temporal lobe. (Spectral edge frequency 50% of alpha spectrum band) induces an increase in concentration is effective.본 발명은 집중력 증가용 향료 조성물, 상기 향료 조성물을 포함하는 집중력 증가용 건강기능식품 및 화장료 조성물과 집중력 증가 효과를 지니는 향료 혼합물의 제조방법 및 상기 방법으로 제조된 집중력 증가 효과를 지니는 향료 혼합물에 관한 것으로, 본 발명의 향료 조성물은 우측 전전두엽, 우측 전두엽, 중앙 전두엽 및 우측 후두엽에서 RB(Relative beta power spectrum)의 증가를, 우측 전두엽, 중앙 전두엽, 우측 후두엽 및 좌측 후두엽에서 RG(relative gamma power spectrum)의 증가를, 우측 전전두엽, 우측 전두엽, 중앙 전두엽, 중앙 두정엽 및 우측 후두엽에서 RHB(relative high beta power spectrum)의 증가를, 우측 후두엽에서 RSMT(ratio of (SMR~mid beta) to theta power spectrum)의 증가를, 우측 전
