  • Method for bleaching nuts
    Patent number: 5871800
    Abstract: A method and apparatus for bleaching the shells of in-shell nuts and for bleaching the meats of shelled nuts involves wetting the nuts with an alkaline solution and then with a peroxygen solution. The two substances react to form a bleaching agent which whitens the shell or nut meat. Slight mechanical brushing may be used to dislodge debris loosened by the process. The apparatus includes means for recycling the reagents through the system without causing the desired temperature and concentration of the reagents to deviate significantly from predetermined values.
