CASTANO, M.N et al. Caracterización de harinas de tritíceas híbridas. Agriscientia [online]. 2017, vol.34, n.1, pp.15-25. ISSN 1668-298X.

Triticales (x Triticosecale Wittmack) and Tricepiros (x Triticosecale Witt. X x Agrotricum A. Camus) are improved in order to obtain dual-purpose cultivars (forage and grain). In order to use them for human consumption the quality of triticale four is frequently evaluated by measuring the diameter and spread factor of cookies. These indicators are strongly related to the contents of damaged starch, protein and non-starch polysaccharides of four, which determine its water absorption properties. During 2012, twenty-five experimental strains, eight triticale and one tricepiro cultivars were evaluated in Santa Rosa, La Pampa, Argentina by means of simple correlation and cluster analysis. Positive correlations between the values of solvent retention capacity of water, sodium carbonate, lactic acid and sucrose, retention rate of alkaline water, soluble pentosans and damaged starch were observed. The characterization of the tested fours and their differentiation based on their physicochemical properties allowed the selection of genotypes with different functional properties. In the cluster analysis, cluster 1 pooled the materials with the best physicochemical features of four, which increases the possibilities of its use for human consumption.
