Abstract
The cooking quality of irradiated chestnut after longterm storage were evaluated. 1. Color degree and tannin content of irradiated chestnut were slightly increased with the storage, but there was a little difference according to the radiation dose after nine months storage. 2. The main component of free sugars in the irradiated chestnut were identified as sucrose, glucose, fructose and the amino acids of chestnut were identified in the decreasing order of glutamic acid, aspartic acid, leucine, arginine, glycine, alanine, serine, pheylalanine, threonine, valine, isoleucine, tyrosine, methionine and cystein. Free sugars and amino acids of 25 Krad irradiated group showed a little difference compared with those of control group after nine months storage. 3. The calorie of candied chestnut prepared from nine months stored was marked 199 Kcal/100g of edible parts compared with 159 Kcal of raw chestnut. 4. Texture and sensory evaluation of candied chestnut prepared from nine months stored were better in 20-25 Krad irradiated group than in control group.
방사선(放射線) 조사(照射)에 의한 장기저장(長期貯藏) 밤의 조리적성(調理適性)을 검토(檢討)하기 위한 몇가지 실험을 행하여 다음과 같은 결과를 얻었다. 1. 밤의 갈변요인인 색도(色度)와 tannin성 물질은 저장기간이 경과할 수록 다소 증가하였으나, 저장말기(貯藏末期)에 조사선량(照射線量)에 따른 차이는 나타나지 않았다. 2. 저장말기(貯藏末期) 밤의 정미성(呈味性)에 영향을 주는 유리당(遊離糖) 및 아미노산 조성(組成)은 적정조사선량(適正照射線量)인 25Krad구(區)에 있어 조사(照射)에 의한 영향은 보이지 않았다. 3. 저장말기(貯藏末期) 밤으로 제조한 밤초의 열량은 199Kcal/100g으로서 생밤의 159Kcal/100g 가시부에 비해 25%의 열량 증가를 보여 고(高)칼로리 영양식으로 기대된다. 4. 저장말기(貯藏末期) 제조한 밤초의 질감(質感)과 관능성(官能性)은
