초록

본 연구에서는 2003년 7월에서 2004년 6월까지 충청도와 전라도 지역에서 집유한 원유의 비타민 A, E, $B_l$$B_l$ 함량을 1년간 분석함으로써 우유에 함유된 비타민의 최근 동향 및 계절적 변화를 조사하고자 연구를 진행하였다. 이 중 지용성 비타민 A와 E의 함량에는 계절적 변화가 있었으며, 비타민 A의 경우 봄($3월{\sim}5월$)은 $35.1{\sim}59.0{\mu}g/100mL$로 평균 $44.4{\mu}g/100mL$, 여름($6{\sim}8월$)은 $36.7{\sim}65.6{\mu}g/100 mL$로 평균 $50.0{\mu}g/100 mL$, 가을($9월{\sim}11월$)은 $28.7{\sim}61.2{\mu}g/100 mL$로 평균 $46.8{\mu}g/100 mL$이었으며, 겨울($12월{\sim}2월$)은 $29.9{\sim}57.8{\mu}g/100mL$로 평균 $43.1{\mu}g/100 mL$를 나타내어 우유 중 비타민 A함량은 여름철이 가장 높고, 겨울철이 가장 낮은 것으로 나타났다. 비타민 E의 경우 봄($3월{\sim}5월$)은 $28.3{\sim}59.2 {\mu}g/100 mL$ 로 평균 $45.8 {\mu}g/100 mL$, 여름($6월{\sim}8월$)은 $39.6{\sim}69.9 {\mu}g/100mL$로 평균 $58.8{\mu}g/100 mL$, 가을($9월{\sim}11월$)은 $35.0{\sim}62.8{\mu}g/100 mL$로 평균 $46.2{\mu}g/100 mL$이었으며, 겨울($12월{\sim}2월$)은 $26.0{\sim}55.4{\mu}g/100 mL$로 평균 $41.5 {\mu}g/100 mL$이었다. 분석결과에서 알 수 있듯이 원유 중 비타민 E함량은 여름철이 가장 높고, 겨울철이 가장 낮은 것으로 나타났다. 그러나 수용성 비타민 $B_l$$B_2$의 경우는 계절에 따른 변화가 없었으며(p<0.05), 비타민 $B_l$의 경우 봄($3월{\sim}5월$)은 $27.7{\sim}57.9{\mu}g/100 mL$로 평균 $42.84{\mu}g/100 mL$, 여름($6월{\sim}8월$)은 $32.4{\sim}66.1{\mu}g/100 mL$로 평균 $49.39{\mu}g/100 mL$, 가을($9월{\sim}11월$)은 $34.1{\sim}63.7{\mu}g/100 mL$로 평균 $46.69{\mu}g/100 mL$이었으며, 겨울($12월{\sim}2월$)은 $20.6{\sim}61.4{\mu}g/100 mL$로 평균$43.26{\mu}g/100 mL$로 측정되었다. 비타민 $B_2$의 경우는 봄($3월{\sim}5월$)은 $150{\sim}182{\mu}g/100 mL$ 로 평균 $166{\mu}g/100 mL$, 여름($6월{\sim}8월$)에는 $145{\sim}185 {\mu}g/100 mL$로 평균 $163 {\mu}g/100 mL$, 가을($9월{\sim}11월$)은 $149{\sim}180{\mu}g/100 mL$로 평균 $166{\mu}g/100 mL$이었으며 겨울($12월{\sim}2월$)은 $148{\sim}190{\mu}g/100 mL$로 평균 $167{\mu}g/100 mL$로 측정되었다.

This study was performed to investigate the changes of vitamin A, vitamin E, vitamin $B_l$ and vitamin $B_2$ contents in cow's raw milk collected from dairy farms in Chungcheong-do and Jeolla-do for a year. The contents of fat soluble vitamin A and E were changed as seasonal effect, but water soluble vitamin $B_l$ and $B_2$ contents were not changed as seasonal effect. Vitamin A content in cow's raw milk was as follows [minimum ${\sim}$maximum (mean), ug/100 mL]; $35.1{\sim}59.0$ (44.4) in spring, $36.7{\sim}65.6$ (50.0) in summer, $28.7{\sim}61.2$ (46.8) in autumn and $29.9{\sim}57.8$ (43.1) in winter. In case of vitamin E was as follows [minimum${\sim}$maximum (mean), ug/100 mL]; $28.3{\sim}59.2$ (45.8) in spring, $39.6{\sim}69.9$ (58.8) in summer, $35.0{\sim}62.8$ (46.2) in autumn and $26.0{\sim}55.4$ (41.5) in winter. In case of vitamin $B_l$ was as follow [minimum${\sim}$maximum (mean), ug/100 mL]; $27.7{\sim}57.9$ (42.84) in spring, $32.4{\sim}66.1$ (49.39) in summer, $34.1{\sim}63.7$ (46.69) in autumn and $20.6{\sim}61.4$ (43.20 in winter. The amounts of vitamin $B_2$ in cow's raw milk was as follows [minimum${\sim}$maximum (mean), ug/100 mL]; $150{\sim}182$ (160 in spring, $145{\sim}185$ (163) in summer, $149{\sim}180$ (166) in autumn and $148{\sim}190$ (167) in winter.
