초록

본 시험은 브랜드 쌀의 연차가 변이와 품질 수준을 점검하고 지속적인 품질 평가를 통한 브랜드 쌀의 인지도를 높여 소비자의 신뢰를 확보하고자 시험을 실시하였으며 그 결과는 다음과 같다. 1. 본 시험기간중 기상은 2002년 9월 중순부터 기온이 많이 낮아졌으며, 2003년은 7월과 8월의 기상이 상대적으로 낮게 경과하였고, 일조시수 또한 적어 벼의 생육에 많은 영 향을 미쳤으나 2004년은 벼가 생육하기에 가장 적당한 기온을 보였다. 2. 도내 브랜드 쌀의 3개년간 분석 성적에서 완전미율이 CV가 1.9%로 브랜드간 변이가 가장 작았으며, 식미치 또한 4.2%로 변이는 적은 편이었다. 3. 완전미의 최하위와 최상위의 범위는 2003년도에서 가장 넓게 나타났으며 그에 따라 평균 완전미율 또한 가장 낮게 나타났다. 4. 평균 단백질 함량이 2003년에 8.0%으로 2004년에 7.0%에 비해 약 1.0%정도 높았으며, 특히 2004년의 경우 단백질 함량이 7.0% 이하인 브랜드가 65.4%를 차지하고 있어 감비재배의 효과와 등숙에 알맞은 기상의 영향을 많이 받았던 것으로 사료된다. 5. 기상이 양호했던 2004년에는 심복백미 비율이 $0.3{\sim}5.9%$였고 평균 2.8%로 이상 기온 현상이 있었던 2003년의 절반 정도로 감소되었다. 심복백미 비율이 3% 이상 되는 브랜드 수 또한 2003년에 73.6%를 차지해, 2002년의 53.2%와 2004년의 46.2%에 비해 높아서 외관상 품위를 떨어뜨리는 가장 큰 요인으로 작용하였다. 6. 연도별 식미치는 완전미 비율이 가장 높았고, 단백질 함량이 가장 낮았던 2004년도에서 평균 77.0으로 가장 높았고, 그와 반대로 완전미 비율도 낮았고, 단백질 함량이 가장 높게 나타났던 2003년도에 71.0으로 낮았다.

Rice quality must certainly be considered as one of the primary preference for consumers. On aspect concerns marketing, such attributes as appearance, physicochemical characteristics, and palatability of brand rice are very important. Therefore this study was carried out to observe the quality of commercial brand rice in Gyeongbuk Province, Korea from 2002 to 2004. In seasonal changes of mean air temperature from early July to middle August, it was lower in 2003 by $0.8{\sim}3.3^{\circ}C$ than that in normal year. Among the rice quality characteristics, the cv of percentage of head rice and palatability (Toyo value) were very low but those of chalky rice and protein content were very high during three years, and the same tendency was also observed among the brands. The average percentages of head rice were 92.5% in 2002, 89.9% in 2003 and 93.3% in 2004, respectively. On the contrary, the percentages of chalky rice were higher in 2003 as 4.9% than those in 2002 (3.9%) and in 2004 (2.8%). These results were caused by the abnormal meteorological conditions in 2003. Due to the higher protein content (8.0%) in 2003, the palatability was deteriorated to 71.0. However the protein content in 2004 was reduced to 7.0% and this result improved the palatability to 77.0.
