Onion skin is a waste produced during onion bulb processing. Recent studies have reported that it contains large amounts of bioaccessible and bioavailable compounds thus it can be used to design of novel food products. The objective of the study was an attempt to substitute semolina with onion skin (OS) powder in pasta at 2.5, 5 and 7.5 g/100 g levels. The effects on the chemical composition, antioxidant potential, technological and sensory properties of the fortified pasta samples were evaluated compared with a control sample. Fortification with OS resulted in a significant (P < 0.05) improvement in nutritional properties, which was demonstrated by an increase in the content of dietary fibre, ash, total phenolic compounds, flavonoids content and antioxidant activity (FRAP and DPPH). Cooking loss increased with increasing levels of OS, however, all pasta samples were in the acceptable range (8 g/100 g). Onion skin incorporation decreased optimal cooking time, water solubility index and increase redness (a*), compared to the control sample. Results of sensory evaluation suggest that pasta, in which 2.5% of the flour was replaced by this plant component, showed the highest value of the "overall quality". Our study indicates that onion skin powder can be a potential alternative for the food industry to provide nutritional enriched pasta.

In recent years, natural food colouring components have been sought. The conducted study presents the possibility of using different legume flours as a colouring component in durum wheat semolina pasta. The impact of legume flours addition on chemical composition, cooking quality, and sensory properties of pasta was also investigated. The pasta was fortified with 0-20% of green pea, red lentil, and grass pea flours and was made using lamination technology. An increase in the amount of the legume flour caused a significant increase in the content of dietary fibre, ash, protein, and essential amino acids, including lysine. The addition of the legume flours changed the colour of the pasta samples. Most suitable colouring component of all the studied legume flours was the red lentil flour. The pasta with 20% addition of red lentil flour had the most intense colouring (DE = 11.31), highest level of consumer acceptance and were characterized by acceptable cooking losses (7.47% d.m.), appropriate weight increase index (2.44), and high firmness.

Pasta production is a good opportunity for product innovation in different forms. The aim of this work was to assess the use of flaxseed components for pasta production. We examined the chemical composition and cooking quality, at different contents of flaxseed flour (FF) and flaxseed cake (FC), added for pasta processing. The analysis showed that the addition of flaxseed components to the dough caused a substantial difference in the International Commission on Illumination color model (CIE) parameter, compared to control samples. The samples of pasta with FF and FC were darker, redder, and less yellow than the control. The minimum cooking time for the enriched pasta was longer than that for the control pasta, although cooking losses were lower. The increasing content of flaxseed components did not significantly change the weight and volume increase index. The enrichment of pasta with 23% FF and 17% FC yielded good quality pasta. The results of the chemical composition of the flaxseed-enriched pasta indicate considerably enhanced nutritional quality, particularly the levels of protein, fat, and dietary fiber of the pasta, without affecting its quality. Moreover, flaxseed cake can be an important source of nutritional ingredients for pasta production, although it is a by-product of the oil cold pressing technology.

Hemp seed (Cannabis sativa L.) contain large amounts of nutrients, e.g. protein, dietary fiber, minerals, and unsaturated fatty acids, which make them a good fortifying component in food production. The aim of the present study was to determine the effect of hemp addition on the physicochemical properties, cooking quality, texture parameters and sensory properties of durum wheat pasta. The samples were fortified with 5–40% of commercially available hemp flour or 2.5–10% of hemp cake obtained from hemp seed oil pressing. Our study showed that the addition of hemp seed raw materials led to an increase in the protein, total dietary fiber (TDF), ash and fat content in the pasta samples. Due to its lower granulation and higher nutritional value, hemp flour was found to be a better raw material for the fortification of pasta than hemp cake. Pasta enriched with hemp flour at the level of 30–40% contains 19.53–28.87% d.m. of protein and 17.02–21.49% d.m. of TDF and according to the EU, a definition can be described as a high-protein and high-fiber products. All enriched pasta samples were also characterized by safe Δ-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) content, and their sensory properties were accepted by consumers.

Background. The aim of the study was to determine the possibility of full or partial replacement of durum semolina with cheaper common wheat flour to obtain high-quality pasta. It also examined whether the addition of eggs could minimize qualitative changes in these products. Material and methods. In eggless, one-egg and two-egg pasta, semolina durum was substituted with common wheat flour to a degree of between 0-100%. The study was carried out in semi-technical conditions with the use of a MAC 30S-Lab Pasta Extruder and an EAC 30-Lab Pasta Dryer. The physicochemical parameters and cooking quality of the pasta samples were tested. Results. The results showed that the addition of the common wheat flour reduced the protein and dietary fibre content in the pasta, increased losses of dry matter during cooking, and decreased the yellowness index. However, it increased the weight increase index and shortened the cooking time. Adding eggs significantly improved the quality of the common wheat pasta. Conclusion. On the basis of the tests carried out, it was found that the addition of common wheat flour to eggless and one-egg pasta should not exceed 50% and 60%, respectively. It was shown that on adding two eggs, 100% of durum semolina could be replaced with common wheat flour without any significant deterioration in the quality of the product.

Background and Objectives: There is a growing demand in the food market for vegan and vegetarian products. However, they often contain incomplete protein and small amounts of protein. Therefore, plant-enriched products with increased nutritional and biological value are increasingly being sought. This study was undertaken to determine the effect of adding wheat germ (WG) (wheat milling by-product) and wheat germ protein isolate (WGPI) to durum wheat pasta. The aim of this study was to obtain high-protein wheat pasta with an improved amino acid composition. Another objective was to evaluate the physicochemical parameters and assess the cooking quality of obtained pasta samples.
