Tenax-TA와 동적 headspace 향 포집방법을 이용하여 볶음들기름의 향기성분을 농축하였다. 이때 반응표면분석법을 이용하여 Tenax-TA에 결합한 향기성분의 탈착에 의한 손실을 최소화하고 휘발성이 낮은 화합물의 포집 효율을 극대화시키는 최적조건을 결정하였다. 독립변수로 향 포집 온도와 시간 및 시료량을 설정하였고 총 peak 면적, 탈착율, 휘발성이 가장 낮은 화합물인 perilla ketone의 면적을 종속변수로 하였다. 등고선 그림을 겹친 결과 0.6 g의 볶음들기름을 48$^{\circ}C$에서 12분 동안 포집시키는 것이 최적조건이었으며 Tenax-TA에서 탈착되는 주요한 휘발성 화합물은 2-propanone, 2-butanone, acetic acid 및 2-methyl propanal이었다.

Dynamic headspace purge conditions were investigated to obtain minimum loss of high volatile compounds by breakthrough and maximum recovery of low volatile components of roasted perilla seed oil (RPSO). A response surface methodology was applied to evaluate the effect of purge temperature, purge time, and sample weight on $\ell$ n (total peak area), breakthrough ratio, and peak area of perilla ketone the least volatile component of RPSO. Sample weight was the most important factor on the $\ell$ n (total peak area) but it did not affect peak area of perilla ketone. All process variables significantly influenced breakthrough ratio. The optimum condition was determined by superimposing contour plots at purge temperature of 48$^{\circ}C$ for 12 min purge time at sample weight of 0.60 g. 2-Propanone, 2-butanone, acetic acid, 2-methyl propanal were main breakthrough compounds in RPSO flavor.

3) Experimental runs were performed in random order.
제안 방법
Sometimes such result was occurred when the pure error was too small by the uncertain experimental factors and it was recommended to add higher order terms in the model or transform the response variables more proper form10). In this study, among the various transformations of the response variables, log transformation and the quadratic model gave the best results in the case of TPA and BTR, respectively. However they had a significant lack of fit yet, nevertheless, it could be used for a useful predictive tool of responses.
It can predict and visualize the effects of changing more than two interac ting factors simultaneously on the responses clearly by mathematical models fitted to data using least square methods and three-dimensional response surface or contour plots10). The objectives of the present study were to establish optimum purge conditions for obtaining minimum loss of high volatile compounds by break through and maximum recovery of low volatile compo nents of RPSO by RSM and identify the breakthrough flavor compounds of RPSO.

대상 데이터
A central composite rotatable design10) with three-level and three-factor was used. The design was composed of 23 factorial points, 9 center point replicates, and 6 axial points. The actual values and coded values of three factors were Table 1.
이론/모형
Statistical analysis was performed using the RSREG procedure of the Statistical Analysis System12). The fitted quadratic polynomial equation was expressed graphically by means of the Response Surface Design of JMP13) to create contour plots.
. Therefore, the random-centroid optimization method was used for determining the optimum purge condition. However, this method was difficult for the interpretation and prediction of the responses along with major factors.

4) Coefficient of variations of Y1, Y2 and Y3 at center point were 0.75, 2.33, and 9.84%, respectively.
60 g, purge time느 15 min), the temperature had a significant effect on the BTR because of relatively low portions of breakthrough of high volatile compound compared to total volatiles entrapped in Tenax-TA trap 1. In this study, the grand average of breakthrough ratio was 6.30% and had the range of 1.63 — 10.54 %, At center point, the average ratio and ratio of trap 2, 3, and 4 were 6.91, 4.95, 1.52, and 0.43 %, respectively (Table 2). Buck holz et alV reported that acetaldehyde, acetone, isobutyraldehyde, isovaleraldehyde, 2-methyl butanal, and pentanal were breakthrough compsmds in ro asted peanut flavor.
Adequacy of the model was tested experimentally at the optimum purge condition. The experimental results of TPA( ℓn) were 13.71 ~ 13.84 (mean 13.78), BTR 5.54〜5.88 % (mean 5, 71 %), and PAPK 15414~15992 (mean 15703). These values were reasonably close to the predicted value, indicating that the model was adequate for dynamic headspace purge process of the RPSO in narrow experimental region.
