This is an experiment. Please help me if you know the answer.?

We have added starch to pancreatin. You know that pancreatin contains several enzymes: amylase, lipase. trypsin and chymotrypsin, and nucleases. So basically, it'll breakdown starch into maltose. Then we added benedict reagent and heated it for about 5 minutes. It turned dark green solution! There is no brick red precipitate as we've all expected. What could be possibly the reason behind this? Thanks :)
