Beyond Meat claims its newest version of the Beyond Burger includes marbling.

In a company news release, the maker of the plant-based burger claims the new product features “marbling designed to melt and tenderize like traditional ground beef.”

The so-called marbling is made from a blend of pea, mung bean and rice proteins. The product is shipping to grocery stores this week. The company called the new product the next step toward “building meat directly from plants that delivers a consumer experience indistinguishable from its animal protein equivalent.”

However, while the company is marketing new products, meat industry publication Meatingplace points out that shares of the company earlier this week fell 25 percent after JPMorgan analysts downgraded the company stock rating. Analysts cited the likely emergence of competitors, including big food companies like Tyson Foods and Nestle. Beyond Meat was founded in 2009 and went public last month. Shares have risen by more than 500 percent since the company went public.
