Professor Roger Lentle
Professor Roger Lentle, from the Institute of Meals, Nutrition and Human Health at the Massey University, led a group that studied how an extract of the mamaku fern influenced stomach activity. Maori traditionally used mamaku to treat diarrhoea and other stomach complaints, but the way it works has not been totally studied.
?The extract comes out of the pith and fronds of the mamaku,? he says. ?It?s a really bizarre substance: it?s stringy and doesn?t move the way in which an odd liquid flows. The more you stir it the extra it resists the flow, and the more it flows the extra it stretches.?
These traits referred to as sheer thickening and extensional flow are distinctive on this planet of edible plant gums. Professor Lentle says this implies the extract might flow in a different way within the intestine to other carbohydrate gums, tricking it into sensing it is full.
?We all know that contractions in the intestine are attributable to it feeling there is something in there and needing to push it on,? he says. ?But this extract seems to dupe the sensory nerves within the stomach in order that they sign the stuff is flowing when it isn?t, and vice versa. This seems to confuse the stomach's pumping system, inflicting it to grow to be less efficient.?
The gum then builds up within the antrum, the part of the stomach close to the gut, giving the feeling of satiety, or feeling full when it is overloaded. ?We expect that the peculiar impact of the gum of stream is what generates the reputed feeling of satiety,? Professor Lentle says. ?What?s extra its distinctive properties in resisting circulate might make the feeling last more.?
He says the extract was drawn to his attention by Affiliate Professor Kelvin Goh, who carried out the initial purification. ?He instructed me about it and I saw the potential, so we began testing,? Professor Lentle says.
He believes there's potential for a business farming operation. ?There is an opportunity there. This extract reveals the gum could have vital potential as an urge for food suppressant, and it's all natural but extra analysis needs to be performed on dose and security.?
Professor Lentle is keen to work with iwi willing to additional investigate the potential of the extract.
