Abstract: A method is provided for fermenting and dehydrating food items such as nuts and seeds to create novel postbiotic foods with numerous benefits. The method comprises preparing a brine solution and adding it with the food item, a sugar product, and select live bacteria cultures to a fermentation vessel. The vessel ferments for 10-14 days at 60-64° F. until a pH of 3.3-4.0 is achieved. The food item is strained, placed on dehydrator trays, and dried at two temperatures to reduce moisture. The process increases nutrition, digestibility, gut health, and safety by reducing antinutrients, agricultural pollutants, toxins, and pathogens by over 5 logs, exceeding pasteurization requirements. The dehydrated food can be packaged or further processed into items like nut butters. The method generates durable, functional nutrition without damaging heat or chemicals.
