후지 사과의 품질분포 조사를 위하여 재배면적 기준으로 5지역(청송, 예천, 봉화, 상주, 예산)을 선정하여 이 지역으로 부터 생산된 후지 사과를 3년간 수집하여 외적, 내적 품질인자를 분석하였다. 후지 사과의 적색도 평균치는 88.94%이었고 년도별로는 3차년도가 93.88%로 가장 높은 값을 보였다. 세로 크기는 평균 76.76mm 이고 가로 크기는 평균 87.17mm 이었으며 중량은 평균 276.749 이었다. 사과의 외관상 손상정도는 각각
This study was carried out to investigate the quality characteristics and its distribution of Fuji Apple produced in Korea. The appels were collected 1mm the major producing areas of the apples, Cheongsong, Yechun, Bongwha, Singju and Yesan. Quality characteristics of the apples produced in these areas for 3 years were measured in terms of redness, size, weight, uniformity, defects, sweetness, firmness, pH and total acidity, The average redness for 3 years in the apples was 88.94% and the apples in the third year had the highest value, 93.88%, in redness. The average size toy 3 years in the apples was 87.17mm and the average weight was 276.74g. In external appearance, defects on the surface of the apples caused by physical factors were more serious than those by insects. Sweetness was 14.81Brix and its variation was 1.78Brix. The average firmness for 3 years in the apples was 0.83kgf, The pH value and total acidity for 3 years in Fuji apples were 3.83 and 0.32 ％, respectively, and the values had no significant difference between production years. According to the producing areas, the apples of area A in redness showed the highest value, 91.10% and these of area D showed the lowest value, 86.15%. The highest value for size was 88.12mm for area C and the lowest value was 86.40mm for area D. The apples of area B had the heaviest weight, 280.49g and these of area D in weight had the lowest value, 273.89g. No great difference showed in external defects and total acidity of the apples among the areas. In sweetness by districts, the apples of area E had the highest value, 15.32Brix, while area B was for the lowest value, 14.58Brix. The firmness of Fuji apples produced in area D and E was the highest value, 0.83kgf, and the apples of area C were the lowest value, 0.76kgf far firmness.
