Residual Nitrite and Rancidity of Dry Pork Meat Products -A Rancidity and Storability of Home-made Dry Sausage and Dry Ham and Public Taste of Dry Ham-

돈육가공저장식품(豚肉加工貯藏食品)의 Nitrite 잔존량(殘存量)과 지방산패(脂肪酸敗) -가내제조(家內製造)한 Dry Sausage와 Dry Ham의 지방산패(脂肪酸敗) 및 저장성(貯藏性)과 Dry Ham의 기호도에(嗜好度)에 관(關)하여-

The long-term storability of home-made dry sausage and ham in terms of peroxide value and thiobarbituric acid value, the effects of nitrite and NaCl contents on the deterioration of the products and the public acceptance of dry ham were studied. The results of this study are as follows: 1. Because the storability of the dried meat products is mainly affected by the fat rancidity of the fat content, POV of 10 was assumed the critical point of storability. The sample dry sausage used in this experiment has lost its storability within a ripening period of 5 weeks. And dry ham was lost its peculiar relish within 50 days. 2. The variations of the NaCl contents of the dry products were reflected in the ripening process. The correlation coefficient between the variations of the NaCl contents and the decrease in the weight of the dry ham was 0.85. 3. The survey of public taste for dry ham was conducted on 35 college students, who think it a bit tasteful or tasteless account for 66% of the total and those who think it a simple relish account for 60%, thus indicating that the dry ham still remains far away from the dining table.

돈육(豚肉)을 원료(原料)로 하여 가내제조(家內製造)한 dry sausage와 dry ham의 저장성(貯藏性)을 지방(脂肪)의 산패(酸敗)로서 측정(測定)하고 nitrite의 확산화효과(擴酸化酵果)를 조사하였다. 또한 dry ham에 대(對)한 기호도조사(嗜好度調査)를 하였다. 그 결과(結果)는 다음과 같다. 1. 주(主)로 지방(脂肪)의 산패(酸敗)에 기인하는 dry sausage와 dry ham의 저장성(貯藏性)은, POV 10을 기준치로 하였을 때 dry sausage는 35일(日) 정도, dry ham은 50일(日) 이내(以內)에 그 저장성(貯藏性)이 상실된다고 보인다. 2. 건조육제품(乾燥肉製品)의 NaCl 함량변화(含量變化)는 가공육(加工肉)의 숙성과정(熟成過程)을 그대로 반영(反映)하며, dry ham의 중량감소와의 상관계수는 0.85였다. 3. 대학생(大學生) 35명(名)을 대상(對象)으로 한 ham의 기호도(嗜好度)는 ‘먹을만 하다’거나 ‘맛없다’는 편이 66%나 되며, ‘술안주’로 좋겠다는 편이 60%로서 dry ham의 식생활(食生活)참여는 아직 힘든 것 같다.
