Among cereals, durum wheat has a central role in the Italian diet and economy, where there is a historical tradition of pasta making. In the present study, we evaluated the nutrient and nutraceutical properties of 2 old and 6 modern durum wheat varieties grown under low input agricultural management. Considering the lack of available data on the adaptability of existing durum wheat varieties to the low input and organic sectors, the research aimed at providing a complete description of the investigated genotypes, considering the agronomic performance as well as the nutrient and phytochemical composition. The experimental trials were carried out at the same location (Bologna, Northern Italy) for two consecutive growing seasons

“…Among old wheat genotypes, the khorasan wheat variety (Triticum turgidum spp. turanicum), generally sold under the commercial brand of Kamut ® , has been investigated to assess its bioactive properties (Benedetti et al, 2012;Marotti et al, 2012), but data concerning its agronomic performance in the Italian and European farmland are still limited (Grausgruber et al, 2005;Piergiovanni et al, 2009;Stagnari et al, 2008). Due to the tall-straw habitus, khorasan wheat is unsuitable to conventional agricultural management, since nitrogen inputs cause severe lodging problems.…”

Agronomic traits and deoxynivalenol contamination of two tetraploid wheat species (Triticum turgidum spp. durum, Triticum turgidum spp. turanicum) grown strictly under low input conditions

An evaluation of the agronomic performance of two tetraploid wheat varieties (Triticum turgidum spp. durum, Claudio; Triticum turgidum spp. turanicum, Kamut ® ) grown strictly under low input conditions was carried out over three consecutive cropping years. The study reported grain yield values ranging from 1.8 to 2.6 t ha -1 . Productivity showed to be primarily affected by environmental conditions, while no differences were observed between the two genotypes. The study of the yield components highlighted that the durum wheat variety had a higher plant density than Kamut ® , but this discrepancy was offset by a greater number of kernels per spike and the kernel weight of khorasan wheat. The investigated wheat genotypes were also analysed to assess the mycotoxin (DON) levels of wholegrain semolina and the efficiency of cleaning treatments to reduce contamination. Results showed that both wheat varieties had a good hygienic and sanitary quality with a DON content ranging from 0.35 to 1.31 mg kg -1 , which was lower than the maximum acceptable level set by the European regulation at 1.75 mg kg -1 . In addition, our research work investigated the effects of premilling cleaning procedures, such as water washing and brushing, on mycotoxin levels, which yielded interesting results in terms of decontamination efficiency. These methods were particularly efficient with Kamut ® semolina (46-93% DON reduction), suggesting that mycotoxins accumulate in this variety at more superficial levels than in the durum wheat variety. On the whole, our study provided additional knowledge on the traits to be further improved to respond to low input requirements and to enhance the potential adaptability of wheat genotypes to organic agriculture. Our results emphasized the need to develop wheat varieties that can provide adequate performance without high levels of nitrogen inputs by selecting specific traits, such as kernel weight, spike length and kernel/spike. This may help achieve productivity gains in organic systems.

“…As no drastic modifications on participants diet before recruitment were done, as confirmed by the fact that body weight of participants did not change, it could be supposed that the decrease of Fat Mass is related to the substitution of the type of cereal. It could be speculated that because the type of cereal fiber is highly important, the qualitatively different fiber present in ancient wheat like KAMUT ® khorasan wheat, as highlighted in a previous study [44], compared to a modern wheat, plays a key role in type-2 diabetes prevention. In fact, to reduce variability and to provide a similar fiber amount to each group, products from both kinds of wheat were prepared with the same technological process and had the same fiber content.…”

Purpose Recently, there was an increasing interest on the use of ancient grains because of their better health-related composition. The aim of this study was to evaluate in healthy human subjects the antioxidative and diabetes-preventive properties of ancient KAMUT ® khorasan wheat compared to modern wheat. Methods The study was a randomized, non-blind, parallel arm study where the biochemical parameters of volunteers with a diet based on organic whole grain KAMUT ® khorasan products, as the only source of cereal products were compared to a similar replacement diet based on organic whole grain modern durum wheat products. A total of 30 healthy volunteers were recruited and the intervention period lasted 16 weeks. Blood analyses were performed before and after the diet intervention. The effect of KAMUT ® khorasan products on biochemical parameters was analyzed by multiple quantile regression adjusted for age, sex, physical activity and BMI compared to data at baseline. Results Subjects receiving KAMUT ® khorasan products showed a significantly greater decrease of fat mass (b = 3.7%; CI 1.6-5.5; p = 0.042), insulin (b = 2.4 µU/ml; CI 0.2-4.2; p = 0.036) and a significant increase of DHA (b = − 0.52%; CI − 1.1 to − 0.12; p = 0.021). Conclusions Our study provides evidence that a substitution diet with KAMUT ® khorasan wheat products can reduce some markers associated to the development of type-2 diabetes compared to a diet of modern wheat.
