What is my unknown substance?

In biology class I have to figure out what my unknown substance is and we tested for prescence of sugars, starch, lipids, proteins, and DNA. The only one that came out positive was DNA. The list of possible answers are honey, cream half and half, grape juice, chicken broth, bisquick, and gelatin solution. I know it's not gelatin because it has 100% proteins. I'm thinking it has to be chicken broth because it's a living substance right? idk any help? idk if grape juice and everything else has dna, plus they all have sugar and protein the ones that don't have that much protein is cream half and half with .4 g, grape juice with 1g, and honey .06. So then again i don't think it can be chicken broth because it has 11g of protein
