Method for hydrolyzing shine skin papayas into edible papayas

Abstract

The invention discloses a method for hydrolyzing shine skin papayas into edible papayas, which relates to the field of food processing. The method is implemented by the following steps of: (1) washing the fresh shine skin papayas, peeling the washed shine skin papayas, splitting the peeled papayas, completely removing seeds and flesh and cutting the processed papayas into any size and any shape; (2) weighing the cut papayas, arranging the papayas into soft water or deionized water of which weight is 2 to 5 times that of the weighed papayas, adding ethylene diamine tetraacetic acid (EDTA-Na2) into the soft water or deionized water to adjust concentration to 0.05 to 0.08mol / L, keeping the solution for 10 to 150min after the ethylene diamine tetraacetic acid is completely dissolved, adding white granulated sugar in an amount which is 30 to 65 percent based on the total weight of the added papayas, stirring the solution to dissolve the white granulated sugar, adjusting the pH to be 1 to 3 by using a hydrochloric acid, placing the solution into a stainless steel kettle, heating the kettle until the solution is boiled, keeping the boiled solution for 10 to 30 min to finish the hydrolysis, stopping the heating and cooling the solution to room temperature; and (3) taking the hydrolyzed papayas out for eating. The edible papayas prepared by the method provided by the invention taste properly sour, sweet and thick without acerbity; and the method overcomes the difficulty that the shine skin papaya only has a medicinal or ornamental effect and cannot be eaten, and greatly increases the utilization rate of the shine skin papaya.
