33 - Recycling of brewers’ spent grains by production of pasta with enhanced nutritional value
F. Nocente - F. Taddei - E. Galassi - L. Gazza

The recycling of by-products from agro-food processes is currently one of the main circular economy principles. In this work the major by-product of the brewing industry, the barley spent grain (BSG), was used to enrich semolina to develop dry pasta with an increased potential nutritional value. Three different concentrations of BSG (5, 10 and 20%) were added to the durum wheat semolina. BSG enriched pasta has been compared with traditional durum wheat pasta for the content of proteins, resistant starch, β-glucan, dietary fibre, total antioxidant capacity (TAC) and for sensorial characteristics. Enriched pasta showed an increase in fibre up to 135%, in β-glucan up to 85% and in TAC up to 19%. BSG enrichment involved effects on sensory properties, optimal cooking time, firmness, yellow index and on total organic matter.

 

46 - Cereals and pseudocereals: economic value vs nutritional value
L. Maddaloni - M. Ruggeri - R. Ruggieri - G. Vinci

The world population is expected to exceed 9 billion by 2050 and to support energy needs, current food production will almost have to double. To address future food and nutritional challenges it will be necessary to: i) reduce food waste, ii) find new sources of protein and energy, iii) search for sustainable food sources. In this regard, pseudocereals can represent a good sustainable food alternative. The objective of the study is to compare two food groups, cereals (Wheat, Rice, Corn, Sorghum, Millet, Barley, Oats and Rye) and pseudocerels (Amaranth, Buckwheat, Quinoa and Chia) in relation to their economic and nutritional value. The study highlights the higher nutritional value of pseudocereals correlated to a higher cost currently.
