This has a very high beta carotene levels due to the feed the animals eat, grass, this makes lovely burgundy coloured biodiesel which like shorteneing has a higher cetane rating due to the large amount of embodied energy in the animals fat. Saturated fats are good for fuel not for people. Just do not try it outside of a temperate climate, it gels at quite a high temperature. The moral of this story is that not all biodiesel is straw coloured!
