Gluten-Free Pasta Enriched with Fish By-Product for Special Dietary Uses: Technological Quality and Sensory Properties

Assessment of Nutritional Value and Maillard Reaction in Different Gluten-Free Pasta

Evaluating the nutritional quality and thermal damage effects of gluten-free foods is essential to ensure that people with gluten intolerance or celiac disease can safely meet their needs. In this work, fifteen different commercial gluten-free pasta samples made from cereals, pseudocereals, and pulses, alone or in mixed combinations, were analyzed to assess their nutritional value, essential amino acids composition, and protein chemical score. The occurrence of the Maillard reaction was investigated, and the levels of heat treatment markers (furosine, maltulose, hydroxymethylfurfural, and glucosylisomaltol) were determined. Analysis of the furosine values showed that pasta made with the same raw materials can have different degrees of thermal damage. There was no evidence of the Maillard reaction progressing in the advanced phase in any of the samples tested. Finally, the correlation between maltulose and furosine levels demonstrated the usefulness of combining the two markers to assess the extent of thermal damage.

Carboxymethyl cellulose and psyllium husk in gluten-free pasta

Formulating high-quality pasta from wheat-free materials is a technological challenge. We aimed to make gluten-free pasta with carboxymethyl cellulose and psyllium husk and evaluate their effect on the quality of the final product. Gluten-free pasta was produced from rice flour, white corn flour, potato starch, soy protein isolate, and carboxymethyl cellulose or psyllium husk used as binding agents. Then, we evaluated the effect of these hydrocolloids on the color, texture, cooking quality, and sensory characteristics of the product. The uncooked gluten-free pasta containing psyllium husk showed significantly higher values of hardness compared to the samples with carboxymethyl cellulose, while the cooked pasta with psyllium husk had a significantly lower nitrogen loss. Also, psyllium husk improved the texture of the cooked gluten-free pasta, providing the highest values of resilience, springiness, and chewiness. Generally, the psyllium husk samples received higher quality values for texture, cooking quality, and sensory parameters, compared to the pasta with carboxymethyl cellulose. Psyllium husk showed a better ability to bind gluten-free pasta than carboxymethyl cellulose. Consequently, psyllium husk could become a feasible alternative to wheat gluten in producing high-quality gluten-free pasta.

Influence of Seaweeds on the Quality of Pasta as a Plant-Based Innovative Food

This study evaluated the effect of the incorporation of seaweed on the physicochemical and technological quality of pasta. For this purpose, enriched wheat pastas from different seaweeds (sea lettuce-Ulva lactuca, nori-Porphyra tenera, and wakame-Undaria pinnatifida) were made and compared with durum wheat pasta as a control treatment. Firstly, optimal cooking times were established by visual and instrumental methods. Then, the technological properties of weight gain (WG), swelling index (SI), cooking losses (CL), and moisture (H%) were determined. Protein and fiber analyses, texture profile analysis (TPA), and color measurements were also performed to evaluate the physicochemical properties. Overall, enriched pasta with seaweed revealed slightly shorter optimal cooking times than control pasta. Texture properties were also modified, with a lower value of hardness, and higher values of adhesiveness and resilience. However, due to the low percentages of seaweed (3%), noticeable effects were not appreciated. Moreover, color variations of enriched pasta were relevant due to the difference among seaweeds. Nonetheless, these additions increased the protein content and soluble fiber in these foods. In conclusion, pasta enriched with marine ingredients improved this nutritional profile, and the changes in technological properties did not have a major impact on the product quality.

The effect of the addition of various species of mushrooms on the physicochemical and sensory properties of semolina pasta

Interest in foods enriched with natural ingredients containing bioactive compounds prompts scientists to undertake research to investigate them. This work aimed to evaluate the chemical composition, physical properties, texture, and sensory properties of semolina pasta enriched with 2.5-10% dried mushroom powder (Lion's Mane (L), Maitake (M), Reishi (R), and Enoki (E)). Supplementation with dried mushrooms increased the nutritional value of all the enriched pasta variants, mainly by increasing the content of ash, protein, and dietary fiber. Fortification with Lion's Mane (10%), Reishi (7.5% and 10%), and Enoki (10%) increased the cooking loss of the pasta. A decrease in L* (lightness) and b* (yellowness) was observed in the enriched pasta, with the exception of the cooked E and L samples. Hardness was increased in the Enoki-supplemented cooked pasta. Only the pasta with 7.5% and 10% Lion's Mane and Reishi mushrooms did not have acceptable sensory attributes. Based on the research, the recommended level of supplementation is 5% for Lion's Mane and Reishi, 7.5% for Enoki, and 10% for Maitake mushrooms.
