Lupin legume could be Australia’s soybean
Elizabeth Gracie
ASX-listed regenerative farming business Wide Open Agriculture (WOA) has partnered with Curtin University to develop a new technology that will utilise protein extracted from lupins to create plant-based meat alternatives.
The multiuse food ingredient is environmentally friendly, inexpensive to growers and consumers alike, and could meet the increasing demand for plant-based protein products such as soy.
With the rejection of soy in many countries due to links with cancer from phytoestrogens, lupins are a welcomed alternative.
Lupins, a type of legume, are commonly used to feed livestock and are known for their high levels of nutritional quality.
More than half of the world’s lupins are grown in Western Australia alone, making this a uniquely Australian opportunity.
“Given the growing demand for plant-based protein food ingredients, this new technology could provide a cost-effective solution to using lupin seeds that are grown right here in WA,” said Lead Researcher Stuart Johnson from Curtin’s School of Molecular and Life Sciences.
The already thriving plant-based protein industry is currently worth $19.5b USD and is expected to grow to $40b USD by the year 2025.
When speaking to the ABC, WOA Managing Director Ben Cole said that there were enormous benefits yet to be realized in using lupins as a food for human consumption.
“Lupin is one of if not, the highest legume with very high protein levels; it rivals the market leader soy, but no one has really worked out how to unlock it” said Cole.
When speaking with The Australian Farmer, Johnson said he had been working on the functionality of lupins for nearly 30 years, trying to unlock its potential as a human food to potentially get better returns for growers and have an incentive to plant it as part of a sustainable farming system.
“The modified lupin protein is inexpensive, versatile and clean and green; and may stimulate the increased production of lupins as part of sustainable farming systems in Australia” said Johnson.
According to Dr. Cole, only 4% of lupins are currently consumed by humans, however, he hopes that this technology will allow for greater visibility of lupin products in the plant-based protein market.
“Curtin’s technology represents an opportunity to create a novel plant-based protein that could elevate lupin into a rapidly growing sector of the market” said Dr. Cole.
WOA has begun food-grade trials of lupin protein products which include protein-enriched oat milk, breads, and pasta which will be available within the next three to four months says Dr. Cole.

Trace minerals are required for optimal growth, reproduction, and immunity. Optimising trace mineral status relying solely on oral supplements across a herd may fail because of variation in individual intake and reduced absorption due to antagonism of other ration components and minerals. The use of injectable trace mineral supplements has been associated with positive reproductive outcomes including improved conception rate, increased odds of pregnancy and greater final in calf rate. A study conducted on 2,168 dairy cows, administered injectable trace minerals, four weeks prior to calving and again four weeks prior to the start of mating showed treated animals had a 3.3 per cent greater final in-calf rate, and a reduced time from start of mating to conception, compared to control animals 1 . The Importance of B12 Dr Carl Eden, Technical Services Veterinarian with Boehringer Ingelheim says “Vitamin B12 is sometimes referred to as a ‘super vitamin’ because it is only required in very small amounts but vital to many essential metabolic pathways. However, demand for B12 can vary considerably during the year and we see serum levels of B12 fall at critical times, such as the first few months after calving.” Vitamin B12 contains cobalt, so deficiency in cobalt can lead to deficiency in vitamin B12 because ruminants get most of their B12 as a byproduct of ruminal fermentation where the bacteria in their rumen assemble B12 from cobalt for use by the cow. Sub-optimal trace mineral and vitamin B12 status at calving, mating, and drying off has been shown to negatively impact growth, reproduction, and immunity. Using a trace mineral injectable containing vitamin B12 can improve trace mineral and vitamin B12 status at these critical times. Marks-Min with Vitamin B12 – The Evidence In the largest trace element study to date, Marks-Min Injectable Trace Mineral with Vitamin B12 demonstrated remarkable results when compared to a reference trace mineral injection. “Given the differences between Marks-Min and other products on the market, we wanted to generate a compelling data set to demonstrate how effective it was compared to the pioneer product. We entrusted this work to a third-party research company” says Dr Eden. “We chose farms that were at the top of their game from a reproductive perspective. We made sure that the farms had no evidence of trace element or vitamin B12 deficiencies or excess.” Across all outcomes of interest, Marks-Min demonstrated clear non-inferiority when compared to the reference product. Outcomes measured included submission, pregnancy and conception rates, and six week in-calf rate. Marks-Min demonstrated it is highly suited as an alternative treatment to the reference product.
