Which decays first brown bread or white bread?

Answer:White bread decays first as it holds more moisture, whereas brown bread has more chemicals to keep it fresh. Answer:The rate at which bread will deteriorate depends upon many things including: the formulation, the use of preservatives, the quality of the ingredients, the cleanliness of the production facility and the handling of the product after cooking. I have seen white bread last much longer than some brown breads, and vice versa. Answer:Both ~ about the same.
