Studies on the Effect of Spices and Flavoring on Ascorbic Acid content

조미료(調味料) 및 향신료(香辛料)가 Ascorbic acid에 미치는 조리화학적(調理化學的) 연구(硏究)

The L-ascorbic acid, when various kinds of flavoring and spices were added to it's solution individually or in combination, was determined by the 2,4-Dinitrophenylhydrazine method. The remaining rate of it in the solution, to which such spices and flavoring as vinegar, sugar, salt, glutamic acid-Na, welshonion, garlic, sesame, rice jelly, soy, pimento, hotbean paste, pepper, ginger and cinnamon were added individually, was higher than in the solution of itself alone. In the case of pinenuts, sesame oil and, bean paste, however, the remained total ascorbic acid was of little quantity, The rate of it's autooxidation in the solution added with fennel, cinnamon, ginger, pepper, bean paste, pinenuts, curry in individual were found high, but relatively low in garlic, sesame oil, glutamicacid-Na, sugar, honey, salt, pickled shrimps, hot bean paste, and soy. When combined spices and flavoring were added, the content of ascorbic acid showed high values in all cases, indicating that particularly high in soy-bean sprout namul, chinese radish namul, and muchim, seasoned with the most frequently used flavoring, No. 7,8,9,10 while low values in the combination of mustard muchim.

Ascorbic acid수용액에 조미료 및 향신료를 단독독 또는 배합 첨가(添加)하였을 때의 ascorbic acid의 함량(含量)을 2,4 Dnitrophenylhydrazine method에 의하여 정량(定量)하였다. 조미료 및 향신료를 단독으로 ascorbic acid 수용액에 첨가(添加)하였을 때의 total ascorbic acid의 잔재율(殘存率)은 식초, 설탕, 소금, 미원, 파, 마늘, 깨, 엿, 간장, 고추, 고추장, 후추, 생강, 계피등이 ascorbic acid단독만의 수용액보다 높은치(値)를 나타냈으며 실백, 참기름, 된장의 첨가(添加)는 적은치(値)를 나타냈다. 또한 ascorbic acid의 자동산화율(自動酸化率)은 회향, 계피, 생강, 후추, 된장, 실백, 카레등이 가장 높은치(値)를 나타냈으며 마늘, 참기름, 미원, 설탕, 꿀, 소금, 새우젓, 고추장, 간장등이 대체적으로 얕은치(値)를 나타냈다. 또한 배합(配合)조미료에 있어서는 모두 ascorbic acid의 함량(含量)은 높은치(値)를 나타냈으며 콩나물, 무나물, 무침등 가장 빈용되는 조미료 배합(配合)인 No. 8,9,10이 높은 치(値)를 나타냈으며 겨자채의 조미료배합이 제일 적은치(値)를 나타냈다.
