Plain language summary
The fatty acid composition of retail lamb backfat commonly available in Western Canada was analyzed including lamb collected from a slaughter plant in central Alberta, and backfat collected from racks and chops imported from Australia and New Zealand. Lamb fat from New Zealand was the richest source of what are though of as healthy biohydrogenation products (vaccenic and rumenic acids). Both New Zealand and Australian lamb were the richest source of n-3 fatty acids. North American lamb was richer in t10-18:1, but a subset had fatty acid compositions similar to New Zealand lamb.
Abstract
The fatty acid composition of retail lamb backfat commonly available in Western Canada was analyzed including 16 lambs collected from a slaughter plant in central Alberta, and backfat collected from racks and chops imported from Australia (n = 8) and New Zealand (n = 8). Lamb fat from New Zealand was the richest source of vaccenic and rumenic acids. Both New Zealand and Australian lamb were the richest source of n-3 fatty acids. North American lamb was richer in t10-18:1, but a subset had fatty acid compositions similar to New Zealand lamb.
