Abstract

Quality characteristics (moisture, protein, ash, bulk density, falling number, damaged kernel, and foreign material) of 443 domestic wheat samples harvested between 2011 and 2013 were compared with those of 160 imported wheat samples from the United States, Australia, and Canada. Moisture content of domestic wheat (10.9~13.9%) was generally higher than that of imported wheat (8.0~12.6%). Large variation in protein content was found in domestic wheat compared to imported wheat even though variation in protein content of domestic wheat tended to decrease every year, implying quality control efforts for domestic wheat. A similar trend was observed in ash content, which was approximately 0.1% higher in domestic wheat kernels over 3 years. Imported wheat samples had a falling number of 300 or above. On the other hand, some domestic wheat samples had a falling number of 300, which meant low quality of wheat kernels. Generally, quality variations in domestic wheat kernels decreased over the years; however, it is necessary to maintain minimum requirements of moisture content and falling number for high and consistent quality domestic wheat.

2011년에서 2013년까지 국산 원맥 443점과 수입 원맥 160점의 품질 특성을 비교하였다. 수분 함량은 국산 원맥이 10.90~13.90%, 수입 원맥은 8.0~12.6%로 나타났다. 단백질 함량은 국산 원맥이 9.34~16.1%, 수입 원맥은 9.0~14.6% 범위에 있었다. 회분 함량은 국산 원맥이 1.28~1.89%, 수입 원맥은 1.19~1.74%였으며, 원맥의 단위 밀도는 국산 원맥이 512~859 g/L, 수입 원맥이 789~853 g/L로 수입 원맥의 범위가 더 좁게 나타났다. 국산 원맥의 falling number는 147~822 s로 통상적인 고품질 밀가루의 범위인 300~600 s를 벗어난 300 s 미만의 낮은 품질의 원맥이 존재함을 보여주었다. 반면에 수입 원맥의 falling number는 모두 300 s 이상이며 최대치는 516 s로 모든 원맥이 고품질 범위에 있었다. 피해립과 이물질 함량에서는 국산 원맥이 수입 원맥보다 평균적으로 높은 수치를 보여주었으나, 국산 원맥의 피해립과 이물질 함량은 2011년에서 2013년으로 갈수록 수치가 점차 줄어드는 경향성을 보여주어 지속적인 품질 개선이 이루어지고 있음을 보여주었다.
