Abstract
A method of preparing citrus fruit sections with a fresh fruit flavor and appearance is disclosed. Thick albedo type grapefruit and oranges are cleaned and heated to a core temperature of about 20.degree. to 40.degree. C. They are subsequently scored to the juicy portion, vacuum infused with a commercial pectinase, incubated for critical time and temperature periods, and peeled. The resultant high quality fruit is stored in refrigeration.
Claims3
A method for preparing thick albedo type citrus fruit sections with fresh fruit flavor and appearance comprising in combination the following steps:
- (a) washing the fruit with mild detergent and rinsing;
- (b) heating the citrus fruit to a surface temperature of about 40.degree. to 60.degree. C. and a core temperature of about 20.degree. to 40.degree. C.;
- (c) scoring the peel surface of the fruit so as to barely penetrate the albedo or white layer, but not to penetrate the juice sections;
- (d) vacuum infusing the air bubbles of the thick albedo of the fruit with an aqueous solution of pectinase at about 25 to 30 inches of mercury to replace the gas bubbles in the albedo of the fruit with pectinase solution;
- (e) incubating the fruit for a period of about 10 to 60 minutes at a temperature of about 30.degree. to 60.degree. C.;
- (f) removing the peel and other membrane of the fruit;
- (g) separating each juice section intact from the segment membranes;
- (h) storing the fruit under refrigeration.
