Tomato pomace has the potential to provide additional nutrition and health benefits
According to the US Department of Agriculture, tomatoes are the second most popular vegetable crop behind potatoes, with an annual average per capita consumption of 71 pounds going into juice, sauce and paste. The backstory is that 10-30% of this is seeds, skin and pulp, with no ready market in the human food aisle.

Almost all commercial petfoods contain supplemental choline, predominantly from choline chloride. However, putting choline chloride into the formula can have profound effects on the way the ingredients are combined and processed during production due to the molecule's hygroscopic (water-loving) nature.Dogs and cats, like many other species, require choline
