솔 부추의 향기 성분을 dynamic head space 방법으로 정유 성분을 분리한 다음 GC 및 GC-MS로 분석하였다. 결과는 술피드류가 14종, 알코올이 2종류, 알데히드가 2종류, 푸란 1종류, 산 1종류 그리고 벤젠 1종류로 분석되었다.

딸기의 2차대사에 관하여 phenylalanine ammonia-lyase는 풍미나 색소, 향기 등에 큰 영향을 미치며 숙도 측정지표로 여겨진다. phenylananine amonia-lyase는 숙성 전단계에 걸쳐 활성을 나타내기는 하나 완숙기와 과숙기에 그 활성이 뚜렷이 증가하였다. 이는 딸기의 숙성과 더불어 de novo 합성이 되기 때문으로 보인다. 분자량은 겔 크로마토그래피로 260, 000으로 나타났다.

Experiments were performed using sweet potato starch-wheat composite flours to study the rheology and baking properties of bread with composite flours and to test sensory characteristics. Doughs were prepared from mixtures containing wheat flour and 10, 20, and 30% of sweet potato starch(SPS). Standard methods were used to evaluate the rheology and characteristics of wheat composite flour. The results were as follows : 1. The water absorption, developing time and stability measured by farinograph tended to decrease as SPS contents increased. 2. As the contents of SPS increased, the maximum viscosity of the composite flour by amylograph increased, yet gelatinization temperature was slightly low. 3. In the extensograph, extensibility decreased but the ratio of resistence to extensibility increased in proportion to the contents of SPS. 4. In the quality scoring of the bread, WF, WF + SPS 10%, WF + SPS 20% and WF SPS 30% were 84, 80, 77, 73, respectively. Specific volume and crumb characteristics of bread became inferior as SPS contents increased.
