Description
Sun‑drying prairie turnip is a low‑temperature dehydration method that reduces water activity below 0.6, thereby inhibiting microbial growth while concentrating nutrients.
Technical
During sun‑drying, water is removed from the turnip tissue, lowering the water activity (a_w) below 0.6 and creating an environment hostile to bacteria and molds. The process also concentrates sugars and amino acids, enhancing flavor, and preserves β‑carotene and vitamin C to about 70 % of fresh levels after seven days of exposure.
