Forty wheat samples of ten wheat varieties harvested from optimal or late sowings in 2019 and 2020 were evaluated for nutrient composition. This included crude protein (CP), starch, amino acids, minerals, phytate-phosphorus (phytate-P) and non-starch polysaccharides (NSPs). The objective was to investigate the impact of high temperature on wheat grain quality as a feedstuff for broiler chickens. Growth performance and economic impact of such changes were predicted by the Emmans, Fisher and Gous broiler growth model. On average, 2019 was 1 °C hotter than 2020 during the growing season (Narrabri, NSW 2390, Australia). The wheat harvested in 2019 had higher concentrations of CP, phytate-P, total P and calcium. In 2019, late sowing increased average protein concentrations from 166.6 to 190.2 g/kg, decreased starch concentration from 726 to 708 g/kg and increased total NSPs from 693 to 73.9 g/kg. Unlike the 2019 harvest, the late sowing in 2020 had no impact on CP concentrations in almost all wheat varieties. The 2019 varieties had higher concentrations of 16 assessed amino acids (p < 0.001) compared to the 2020 harvest. The largest difference was in lysine (19.2%), and the smallest difference was in proline (11.1%). It was predicted that broiler diets formulated from 2019 wheat varieties would have better efficiency of feed conversion with an advantage of 2.53% (1.539 versus 1.579) than 2020 varieties to 35 days post-hatch. This would translate to a cost saving of approximately AUD 16.45 per tonne of feed, much of which would represent additional profit.

“…However, since the colonisation of Australia much of this traditional use has not been able to persist, but the strong cultural connections held by many Aboriginal groups do still exist (Williams et al ., 2023). This ongoing connection and the burgeoning native grain industry within Australia (Drake et al ., 2021; Bell et al ., 2022; Jenifer et al ., 2023) has prompted Aboriginal groups to attempt to position themselves as leaders in the production and distribution of the Australian native grain crops that they have used for centuries.…”

SummaryClimate change is threatening our current food systems and countries around the world are seeking alternative food sources to safeguard against potential food insecurity and nutrient deficiency concerns. Various traditional foods used by Aboriginal groups of Australia have previously been shown to be highly nutritious, contain beneficial functional properties and can thrive in the harsh climatic conditions found across Australia. As interest in these traditional foods grows, Aboriginal groups are looking at developing a range of foods for modern markets. However, for many of these foods, there is still little known about their nutritional and functional properties. In this study, we report the nutrition composition and antioxidant properties of a native Australian grain species that is currently being developed for commercial markets by a collective of Aboriginal Traditional Custodians and compare its properties to a commonly consumed wheat variety. Compared with wheat, the native grain species contained 2‐fold greater protein and total fats, and higher levels of essential minerals and trace elements, including 8‐fold iron levels and >2.5‐fold calcium, magnesium, zinc, copper and manganese levels. Functionally, the native grain contained 2.4‐fold greater polyphenol content and displayed greater antioxidant potential in exposed human monocyte cultures. Importantly, the native grain was also found to contain a very low gluten content. Altogether, this shows that the native grain is nutritionally and functionally superior to commonly consumed wheat for the measured parameters and could potentially serve as a grain alternative or be used to fortify current wheat‐based and gluten‐free products.

Utilization of grains of local grasses by Australia’s First Nations people for food and connection to Country has largely been lost due to colonization. Native Australian grain production has the potential to deliver environmental, economic, nutritional and cultural benefits to First Nations people and the wider community. Revitalization of the native grain food system can only be achieved if relevant properties of the grains are elucidated. This study aimed to characterize the grain structure and histochemistry of four Australian native grasses: Dactyloctenium radulans (Button Grass), Astrebla lappacea (Curly Mitchell Grass), Panicum decompositum (Native Millet) and Microlaena stipoides (Weeping Grass). For these species, as well as wheat and sorghum, whole-grain images were obtained via stereo microscopy, starch and the embryo were visualized, and sections of fixed grains were imaged via bright-field and fluorescence microscopy. The shape, size and colour of the whole native grains varied between the species. The aleurone layer was one-cell thick in the native species, as in the domesticated grains, except for Weeping Grass, which had a two-cell-thick aleurone. In the native grains, endosperm cell walls appeared thinner than in wheat and sorghum. Starch granules in Button Grass, Curly Mitchell Grass and Native Millet were found mainly in the central region of the starchy endosperm, with very few granules in the sub-aleurone layer, whereas Weeping Grass had abundant starch in the sub-aleurone. Protein appeared most abundant in the aleurone and sub-aleurone layers of the native grains, although in Button Grass, the starchy endosperm was observed to be rich in protein, as in wheat and sorghum. As a proportion of the whole grain, the embryo was larger in the native species than in wheat. The differences found in the grain properties among the four native Australian species have important implications for the agri-food industry in a changing climate.
