An experiment to make mixed juices carrying the freshness and other specific characteristics of vegetables and fruits which are useful for the prevention and treatment of various diseases was attempted on the emphases of pretreatment methods, combination of fruits and vegetables, and elimination of microorganisms. Blanch in boiling water prior to extraction for green vegetables, addition of ascorbic acid during extraction for tomatoes and apples, or addition of ascorbic acid after blanch in 3% acetic acid for carrots was effective to keep colors and suspended solids in liquid extract.

질병의 예방과 치료에 효과가 있는 채소와 과일을 선택하여 착즙전처리와 배합, 제균방법에 따른 쥬스의 품질특성을 조사하였다. 착즙혼합액의 관능검사 결과 토마토, 사과, 당근, 아욱, 돌미나리+솔잎, 신선초, 대추. 레몬을 선택하여 3 : 3 : 3 : 1/2 : 1/2 : 1/2 : 1/2 : 1/5의 비율로 혼합하였을 때 가장 좋은 선호도를 나타냈다. 녹색채소는 착즙전 비등수에서 데치기를, 토마토와 사과는 착즙시 ascorbic acid를 첨가할 때, 당근은 3% acetic acid에서 데치기를 한 후 착즙시 ascorbic acid를 첨가할 때 착즙액의 색상유지 및 고형물 침전억제에 효과적인 반응을 보였다. 착즙 혼합액을
