Why are the fruit juices bought from the market clearer as compared to those made at home?

The fruit juices which are available in the market in bottles are clearer because they are treated with the enzymes - pectinases and proteases. So, they are clearer as compared to those made at home. Trichoderma polysporum is used to produce cyclosporin A which is an immunosuppressive agent. Monascus purpureus is used to produce statins which are blood cholesterol reducing agents.
