Abstract
Four low fat ground beef groups containing 10% fat plus 0, 5, 10 and 20% additional cooked old rice and a control ground beef containing 30% fat were prepared and their cholesterol contents, calories and production costs were investigated to find out the appropriateness of addition of cooked old rice. There were no differences in pHs with the variations in fat content and the content of cooked old rice. As the amount of added cooked old rice increased from 5 to 20%, cook yield of ground beef also increased. When the fat content of beef was reduced from 30 to 10%, the cholesterol content of beef was not reduced but with the fat content fixed to 10% and the content of added cooked old rice increased from 5 to 20%, the cholesterol content of ground beef decreased. Calories of ground beef were reduced by approximately 50% with the reduction of fat content from 30 to 10% and production costs decreased with the increase in the content of added cooked old rice.
지방과 재고미의 함량 변화에 따른 분쇄 우육의 pH 차이는 거의 없었으며 재고미의 첨가량이 5에서 20%로 증가할수록 가열후 수율도 증가하였다. 10% 지방 우육과 30% 지방 우육의 콜레스테롤 함량은 비슷한 수준이었으며 10% 지방육의 경우 재고미의 첨가량이 증가할수록 제품의 콜레스테롤 함량은 감소하였다. 분쇄 우육의 지방 함량을 30%에서 10%로 줄였을 때 열량은 50% 정도 감소하였고 육 100 g당 생산원가는 재고미를 5, 10, 20% 첨가하였을 때 각각 4.9, 9.9, 19.8%의 비율로 절감되었다. 결론적으로 분쇄 우육의 지방 함량을 30에서 10%로 줄이고 대신 재고미를 첨가하면 가열 수율은 높아지고 열량과 생산 원가는 절감되며 10% 지방육의 경우 재고미의 함량이 증가할수록 콜레스테롤 함량은 감소하는 유익한 효과가 확인되었다.
