Fortification of durum wheat semolina with detoxified matri (Lathyrus sativus) flour to improve the nutritional properties of pasta

Optimization of Nutrient-Rich Ice Plant (Mesembryanthemum crystallinum L.) Paste Fresh Noodle Pasta Using Response Surface Methodology

The ice plant is a species that is grown mainly in the dry regions of the American West and contains various minerals and ingredients beneficial for human health, such as inositol and beta-carotene. With the growing trend towards healthy foods, pasta consumption has also increased. Pasta is a convenient and low-glycemic-index food that is composed mainly of carbohydrates, proteins, lipids, dietary fiber, and trace amounts of minerals. The optimal mixing ratio was evaluated to produce pasta of the highest quality in terms of blood sugar elevation and antioxidant efficacy. The components and minerals of the ice plant, including D-pinitol and inositol, were analyzed, and 20 essential amino acids were identified. In this study, we also investigated the quality and characteristics of ice plant paste and eggs, as well as the quality, antioxidant activity, and formulation of raw materials mixed with ice plant at different ratios. Optimal conditions were found to be 46.73 g of ice plant paste in 100 g of durum wheat flour, 20.23 g of egg, and 2 g of salt, providing a way to develop fresh pasta that enhances the health benefits of ice plant paste without excessive moisture and other ingredients.

Silkworm pupae derivatives as source of high value protein intended for pasta fortification

Silkworm (Bombyx mori) pupae are recognized as novel nutritionally valuable food. Their use in pasta-making was considered with the intention of repositioning spaghetti shaped pasta supplemented with silkworm derivatives (10%_db ) as a valuable product in sustainable diets besides upcycling a side stream from the silk industry. The principal objective of this study was to assess the cooking quality (i.e., imbibition kinetics, cooking loss) and texture of pasta supplemented with defatted silkworm powder or with its aqueous protein extract, which enabled to reduce the content of indigestible components supplying a similar protein intake. Pasta was produced on lab-scale, dried, and tested for chemical composition, mechanical properties before and during cooking, cooking behavior in terms of hydration kinetics, starch gelatinization, and cooking quality indexes. The structural roles on pasta protein network played by silkworm powder and proteins extract were investigated. The former behaves as a structural thickener while the second provides a steric hindrance effect with consequent different cooking performances. With regards to the fortified pasta perceived quality, a high level in total color difference (ΔE) was measured (ΔE > 6). However, after fortification agents' addition, pasta color became closer to that of the whole wheat pasta already known by consumers. Structure fragility increased. The energy at break of the "extract pasta" was about one-third of the control (0.849 N*mm). Silkworm powder addition led to the highest pasta optimal cooking time (376 s) and the slowest imbibition rate (0.0001 s^-1 ). After fortification, pasta had an almost doubled cooking loss than control pasta (2.97 ± 0.18 g/100g_db ). PRACTICAL APPLICATION: Silkworm pupae flour can be easily applied for pasta fortification in order to increase the protein daily intake of people in an easy and practical way.

Modulation in Techno-Functional, Textural Properties, In Vitro Starch Digestibility and Macromolecular-Structural Interactions of Pasta with Potato (Solanum tuberosum L.)

The replacement of semolina with potato flour (PF) and potato mash (PM) at different levels was assessed for its effects on pasta quality. The results showed that the addition of PF and PM increased the pasting viscosity of the blends; in addition, PF enhanced the functional properties, while PM reduced them. The minimum cooking time decreased with PF and PM, while the PF pasta exhibited a higher cooking loss (5.02 to 10.44%) than the PM pasta, which exhibited a lower cooking loss. The pasta with PF and PM showed an increase in the total phenolic and flavonoid content, with reduced in vitro digestibility as confirmed by Fourier transform infrared spectroscopy. The PF pasta exhibited lower lightness and higher yellowness than the PM pasta, and its firmness and toughness also modulated owing to the complex interaction between potato starches and the gluten protein matrix, as evident from scanning electron microscopy. Sensory data revealed that pasta containing 30% PF and 16% PM was highly acceptable.

Wheatgrass powder enriched functional pasta: Techno-functional, phytochemical, textural, sensory and structural characterization

Influence of semolina replacement with wheatgrass powder (WGP) (3-15%) was evaluated with reference to nutritional, techno-functional, phytochemical, textural and structural characteristics of functional pasta. Results showed that incorporation of WGP significantly (p < 0.05) decreased the pasting viscosity of flour blends, while it increases the water and oil absorption capacity and water solubility index. Increased levels of WGP significantly decreased the optimum cooking time from 6.00-4.22 min but increased the cooking loss (2.83-4.36%). Enrichment of pasta with WGP significantly (p < 0.05) enhanced the protein (12.16-17.33 g/100 g), fiber (1.21-4.60 g/100 g), antioxidant activities in terms of DPPH, FRAP, and ABTS. The total phenolic and flavonoid content increased from 56.20-253.90 mg GAE/100 g and 47.41-202.90 mg QE/100 g in the functional pasta. Addition of WGP significantly (p < 0.05) decreased the lightness (L*) while greenness (-a*) of the pasta increased progressively owing to the total chlorophyll pigment. The firmness and toughness of the pasta increased up to 9% WGP level and decreased further, owing to the interaction between WGP protein and fiber with gluten protein matrix as evident from Scanning Electron Microscopy (SEM). Furthermore, cooking of pasta results in significant reduction in all the components in comparison to uncooked pasta. Fourier Transform Infrared (FTIR) spectroscopy further confirmed the presence of phenols, flavonoids and chlorophyll in WGP incorporated pasta. Overall acceptability scores of pastas with 9% WGP found to have highest (7.57), and with increase in further level of WGP, sensory scores decreased (6.55). Moreover, principal component analysis also compliments the sensory results for 9% WGP incorporated pasta.

Effect of Vegetable Juice, Puree, and Pomace on Chemical and Technological Quality of Fresh Pasta

Vegetable pasta is a premium product, and its consumption may deliver health benefits by increasing vegetable intake. This study investigated the replacement of semolina with juice, puree, and pomace of spinach and red cabbage. The effect of replacement on chemical composition, cooking performance (cooking loss, swelling index, water absorption), texture quality (elasticity, firmness), and colour was evaluated. The cooking loss of pasta made with spinach juice and spinach puree at 1 g/100 g substitution was the same as the control, while all other samples had a higher cooking loss. Spinach pasta had a higher breaking force but lower breaking distance in the tensile test than the control, while red cabbage pasta had a lower breaking force and breaking distance. Spinach juice fortified pasta was firmer than the control. Red cabbage juice pasta was less firm than other forms of fortified pasta at 1 g/100 g substitution level. Spinach and red cabbage juice are better colorants than puree or pomace as they change the colour of the pasta more dramatically at the same substitution level. Cooking performance and texture quality of spinach juice pasta were better than other samples, which indicates a premium pasta product for the food industry.

Impact of functional vegetable ingredients on the technical and nutritional quality of pasta

Pasta is a popular staple food around world. This makes pasta a great vehicle for delivering functional ingredients. This article reviews the popular functional ingredients - cereals, pseudocereal, legumes and vegetables, that are used to enrich pasta. The influence of these functional ingredients, additives and cooking process on pasta's nutritional, technical and sensory properties is summarized. This article focusses on the effects of different forms of these ingredients on the quality of cereal foods. Such as carrot juice pasta has a superior technical quality than carrot flour pasta. As far as can be established there are very few articles examining the effects of different forms of ingredients on pasta. Puree or liquid form raw vegetable materials offfers a better option than conventional powder form to add to semolina to produce functional pasta with superior technical quality and improved nutritional value.

Legume flour as a natural colouring component in pasta production

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 (ΔE = 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.
