Use of Integral Forage Palm Flour as an Innovative Ingredient in New Fettuccine-Type Pasta: Thermomechanical and Technological Properties, and Sensory Acceptance.

Dehydrated integral forage palm cladode flour (FPF) presents a promising nutritional and functional approach to enriching fettuccine-type pasta. This study investigated the use of microwave-dehydrated FPF (at 810 W) as a partial wheat flour substitute (0, 5, 10, 15, and 20% w/w) in fresh and dry fettuccine-type pasta. The thermomechanical properties of flour blends and the technological and sensory attributes of the resulting pasta were evaluated. FPF displayed a high protein (15.80%), mineral (15.13%), dietary fiber (67.35%), and total soluble phenolic compound (251 mg EAG·100 g-1) content. While water absorption (~58%) and dough stability remained consistent across formulations, a decrease in maximum torque during heating was observed (p < 0.05). Fettuccine-type pasta containing 10% FPF exhibited an acceptable optimal cooking time, solid loss, weight gain, and textural properties for both fresh and dry pasta. Sensory evaluation revealed acceptability above 63% for pasta with 10% FPF, with a slight preference for the fresh version. Fresh pasta flavored with garlic and extra virgin olive oil (garlic and oil pasta) achieved a sensory acceptance rate of 79.67%. These findings demonstrate the potential of FPF for fettuccine-type pasta production, contributing desirable technological characteristics and achieving acceptable sensory profiles.

Produção e aceitação de massa fresca tipo talharim enriquecida com farinha de maracujá ( Passiflora edulis Sims f. flavicarpa ) e verificação do seu efeito na glicemia / Production and acceptance of a fresh tagliarini pasta fortified with passion fruit flour ( Passiflora edulis Sims f. flavicarpa ) and verification of its effect on the blood glucose levels

OBJECTIVE: To evaluate the sensory acceptance and glycemic response of fresh tagliarini pasta made with passion fruit peel flour. METHODOLOGY: passion fruit peels were dried in the temperatures of 45 °C, 50 °C, and 55 °C, in triplicate. After triturated in a blender the lighter flour was submitted to chemical composition and microbial analyzes. Two recipes were then processed; one containing 25% and another with 35% of passion fruit peel flour. The other ingredients were: white wheat flour, egg, olive oil and water. After homogenization the mixes were worked in a cylinder and cut to obtain the tagliarini form. After cooking them, both tagliarini pastas passed through a sensory test with 130 untrained volunteers. The best formulation was selected for a glycemic response test, in which 20 volunteers received the equivalent of 50 g of carbohydrate; blood glucose levels were measured in the premeal and postprandial periods. RESULTS: The chemical composition analysis showed that fiber was the main flour component, and moisture content and microbiological quality were in compliance with the current legislation. The most accepted formulation (25%) was applied in a glycemic response test. The baseline blood glucose in the experimental group was 93.1 ± 5.31 mg/dL, while the control group was 90.55 ± 8.95 mg/dL. Thirty minutes after consuming the blood glucose, the average in the experimental group was 97.0 ± 9.8 mg/dL and remained constant until 2 hours following the pasta consumption. These values were significantly lower than the average blood glucose measured in the control group after 30 and 60 minutes. This group presented an increase in 19.8 ± 10.1 mg/dL and in 17.8 ± 14.5 mg/dL, respectively. CONCLUSION: The results suggest that passion fruit peel flour can be used in pasta in order to nutritionally fortify the product and help in the glycemic control

OBJETIVO: Avaliar a aceitação sensorial e resposta glicêmica de massa fresca tipo talharim formulada com farinha da casca do maracujá. METODOLOGIA: Cascas de maracujá foram desidratadas nas temperaturas de 45 °C, 50 °C e 55 °C, em triplicata, após trituração em liquidificador; a farinha de coloração mais clara foi submetida às análises de determinação da composição centesimal e microbiológica. Duas formulações de massas foram processadas por meio da mistura dos ingredientes: farinha de trigo sem fermento, ovo, farinha de maracujá nas proporções de 25% ou 35%, azeite e água. Depois da homogeneização, a mistura foi passada em cilindro para extrusão e, em seguida, cortada para obter a forma do talharim. Depois da cocção, as duas massas tipo talharim foram submetidas a teste sensorial com 130 provadores não treinados. A formulação de melhor aceitação foi selecionada para pesquisa da resposta glicêmica, na qual 20 voluntários receberam uma porção com o equivalente a 50 g de carboidrato; a glicemia foi aferida nos períodos pré-prandial e pós-prandial. RESULTADOS: As análises de composição química mostraram as fibras como principal componente, com umidade e qualidade microbiológica adequados à legislação vigente. A formulação de melhor aceitação (25%) foi aplicada para o teste glicêmico. A glicemia basal do grupo experimental foi 93,1 ± 5,31 mg/dL, e a do grupo controle 90,55 ± 8,95 mg/dL. Trinta minutos após a ingestão, a média do grupo experimental foi de 97,0 ± 9,8 mg/dL, mantendo-se constante até 2 horas depois. Esses valores foram mais baixos do que as médias aferidas no grupo controle após 30 e 60 minutos, sendo que esse grupo apresentou um incremento glicêmico de 19,8 ± 10,16 mg/dL e de 17,8 ± 14,49 mg/dL, respectivamente. CONCLUSÃO: Os resultados encontrados sugerem que farinha da casca do maracujá pode ser aplicada em massas alimentícias para auxiliar no controle glicêmico
