There is growing interest in pulses such as faba bean for the development of foods with enhanced nutrition, functionality, and health benefits. In this study, seed material from 10 faba bean varieties, grown in replicated field trials in South Australia over consecutive seasons (2016 and 2017), were analysed for ferric reducing antioxidant potential, total phenolics, and total monomeric anthocyanins. Differences in the macrochemical composition of varieties was investigated using attenuated total reflectance mid-infrared spectroscopy. The mean ferric reducing antioxidant potential of the varieties ranged from 237 to 531 mg trolox equivalents 100 g −1 ; the total phenolics from 258 to 571 mg gallic acid equivalents 100 g −1 ; and the total monomeric anthocyanins from 12.7 to 21.0 mg cyanidin-3-glucoside equivalents 100 g −1 . Statistically significant variances in all three measures were found between varieties.Attenuated total reflectance Fourier transformed mid-infrared spectroscopy was found to provide a rapid assessment of the phytochemical composition of the samples. Partial least squares discriminant analysis was able to classify samples by growing year with reasonable accuracy (>87%). There is significant variation in the antioxidant, phenolic, and anthocyanin contents between Australian faba bean varieties. Mid-infrared spectroscopy may prove to be a valuable screening tool for breeders and researchers in the future.

Mungbeans are growing in popularity among Australian consumers, driven by their beneficial nutritional and phytochemical composition. However, data on the antioxidative, mineral, and phytochemical content of Australian mungbeans at the point of consumer purchase remains scarce. Here, five commercial mungbean samples were analysed for total antioxidant capacity, total phenolics, and total monomeric anthocyanins. Attenuated total reflectance midinfrared spectroscopy was utilised as a rapid and reliable method of obtaining information about the macrochemical composition of the mungbean hulls. Total antioxidant capacity ranged from 170 to 570 mg Trolox equivalents per 100 g, total phenolic content from 130 to 240 mg gallic acid equivalents per 100 g, and anthocyanin content from 10 to 40 mg cyanidin‐3‐glucoside equivalents per 100 g. There was a significant difference between varieties in all measures of antioxidant, phenolic and anthocyanin contents. Using principal component analysis, the midinfrared spectra for the five mungbean varieties could be isolated, highlighting the differences in their phytochemical composition. In general, whole Australian mungbeans appear to have the highest antioxidant, phenolic, and anthocyanin contents. Midinfrared spectroscopy appears to be a valuable method of obtaining and comparing the macrochemical composition of mungbeans. This technology is likely to be of increasing use in the future.

This paper analyses the water quality and environmental determinants for Kelly’s Off Stream Storage, Byfield, Central Queensland with a view to understanding the physical and chemical processes in this section of the water supply system. This assists management in evaluating risks and the need for preventative actions. It illustrates the link between a protected and well vegetated catchment and a high quality and good tasting water supply. The drinking water from the treatment plant associated with this Off Stream Storage has won many awards in taste tests. Key to the quality of this water is the sand filtration in the dunes upstream from Water Park Creek, quality of the catchment, riparian vegetation in the source stream, the pattern of stratification and mixing, conductivity and low concentrations of nutrients.
