Abstract
A product and process of removing the skins from nuts involves wetting the nut kernels with an alkaline solution and then with a peroxygen solution. The two substances react underneath the skin to liberate gas between the nut meat and the skin. The gas bubbles blister the skin, causing it to become loosened. Slight mechanical brushing is used to dislodge the blistered skins from the nut meats.
Claims28
A method for removing skin from nut meats, the method comprising the steps of:
- providing a first chemical solution comprising a solution of a food grade alkaline compound the first chemical solution having a concentration of approximately 1% to saturated, and a second chemical solution comprising a solution of a food grade peroxygen compound that is capable of reacting with the first chemical solution to form a gas, the second chemical solution having a concentration of approximately 10-40%;
- wetting a nut meat with the first chemical solution after removal of the nut meat from its shell;
- wetting the nut meat with the second chemical solution, forming a gas between the nut meat and a skin on the nut meat to loosen the skin;
- and
- removing the skin from the nut meat.
