I get my daily brown bread from a bread outlet down the street. In the last two weeks I found, more than once, torpedo-shaped dark brown objects, approximately the size of a swollen grain of rice in the bread. I was concerned these might be mouse droppings. When I retuned to the outlet, the shop attendant contacted the baker and they told me that it was from the malt they use to darken the bread. I was really surprised and never expected to hear such a thing.
When I cut the bread open the dark brown grains were as soft as boiled rice, and when I rubbed them between my fingers they looked and felt like paste, and after a day or so left out in the open, they hardened.
