The invention discloses a technology for producing a citrus juice sac through the peeling and the capsule dressing removal of whole fruits. The technology comprises the following steps: 1, grinding the fruits or scratching peels; 2, blanching or carrying out compound enzyme processing; 3, carrying out peeling and capsule dressing removal of the whole fruits; 4, carrying out dispersion and impurity removal of the whole fruits; 5, blend-mixing; 6, disinfecting and killing enzymes; and 7, carrying out aseptic loading. According to the invention, fruit grinding or peel scratching preprocessing is adopted, a whole fruit enzyme method is adopted to peel and remove capsule dressings, a whole fruit improvement acid-alkali method is adopted to remove the capsule dressings, and a whole fruit dispersion method is adopted to produce the citrus juice sac which is used as a raw material for a citrus juice with fleshes. The technology of the invention allows labor force to be saved by above 25%, an acid-alkali or enzyme preparation and water for the capsule dressing removal to be saved by about 30%, a raw material loss rate to be reduced by about 15%, and a juice sac breakage rate to be reduced by about 10%, so the production cost can be saved by about 20%, and the juice sac quality can be improved.
