Ms Sowden said in a recent trip to the United States she tasted both alternative burgers.
''For a person who doesn't normally eat burgers and is traditionally a steak eater, I actually couldn't taste the difference between an Impossible Burger and a grainfed United States burger,'' she admitted.
Alternative proteins were here to stay, Ms Sowden said.
''We need to make sure that when we're looking at going into those markets we need to differentiate them and to do that we have to make sure that what we are producing is at the highest standards possible.''
At one of the top end wholefood supermarkets in New York every piece of protein on sale in the butchery was backed by a ''5 Step'' animal welfare programme, Ms Sowden said.
''Most of New Zealand farm systems would only sit at about a three or a four [on the programme], so you can see that consumers are starting to purchase [based] on animal welfare,'' she said.
''Consumers are not only making purchasing decisions on animal welfare, but on 'is this environmentally friendly? Is this sustainable?' And we could, in 10 years time, be looking at 'is this a carbon-neutral farm?''
