발효주의 잔류물질 실태조사를 위해 울산지역에서 유통 되는 발효주 150건을 수거하여 잔류농약 400종과 중금속 납, 카드뮴, 수은을 분석하였다. 잔류농약 분석 결과, 102 건(68%)의 검출을 나타냈으며 검출된 농약 종류는 35종 으로 그 중 원료 농산물의 기준이 없는 농약은 4종이 검 출되었다. 발효주 종류별로 비교하면 와인이 60건의 검사 중 54건(90%)으로 가장 많은 잔류농약이 검출되었고 맥 주는 60건 중 37건(61.7%), 막걸리는 30건 중 11건(36.7%) 이 검출되었다. 발효주에 대한 중금속 분석 결과는 납 73 건(48.7%), 카드뮴은 9건(6.0%), 수은은 36건(24.0%)을 나 타내었다. 납은 73건의 검출 중 와인이 57건(78.1%)을 차 지해 가장 높은 검출을 나타내었고 카드뮴과 수은은 검출 된 9건, 36건 중 막걸리가 7건(77.8%), 13건(36.1%)으로 가장 많이 검출되었다. 각 품목에서 검출된 잔류농약 및 중금속 항목에 대해 인체노출량 평가결과는 모두 1% 미 만으로 안전한 것으로 나타났다.
Scientific studies have shown that essential fatty acidintake can have a dramatic impact on human health. Soybean [Glycine max(L.) Merr.] oil from current commercial cultivars typically containsaround 8%linolenic acid (18:3) known as omega-3 fatty acid. Omega-3 fatty acid plays an important role to prevent cardiovascular disease and cancer. Relatively high 18:3 content in seed oil is a trait of the wild soybean (Glycine soja Sieb. and Zucc.) ancestor of modern soybean cultivars. Wild soybean is native to Korean peninsula and recently thousands of wild soybeans collected by soybean researchers in Korea. The objective of this study were to determine the linolenic acid content for wild soybean collection and to determine the stability of linolenic acid content derived from wild soybean over environments. Fatty acid profile for 1,806 wild soybean accessions collected from South Korea was determined by GC. The range of linolenic acid was 7.3 to 23.7% with an average 15.6%. We developed a recombinant inbred population from a cross PI483463 (wild soybean with 15% 18:3) and Hutcheson (cultivar with 8% 18:3). Three RILs, RIL156, RIL159 and RIL166, with high linolenic acid content (over 14%), parents and Williams 82 as checks were grown in nine environments over 2008-2011. Results showed that the content of linolenic acid for the PI483463, Hutcheson, and Williams 82 ranged from 14.8 to 17.1, 8.5 to 9.7, and 6.9 to 8.4 % and averaged 15.4, 9.2 and 8.0%, respectively. However selected RILs 156, 159, and 166 ranged from 10.7 to 15.7, 14 to 15.8, and 14.8 to 15.8, and averaged 13.9, 14.9, and 15.2, respectively. Among the tested accessions, RIL166 was the most stable with the lowest range and CV, and had a relatively lower stability coefficient value than other genotypes. Genes related to high linolenic acid from wild soybean may be useful in developing higher linolenic acid soybean genotypes and would broaden the use of soybean in food applications to improve human nutrition and health.
