Nutritional, antioxidant, glycaemic index and Antihyperglycaemic properties of improved traditional plantain-based (Musa AAB) dough meal enriched with tigernut (Cyperus esculentus) and defatted soybean (Glycine max) flour for diabetic patients

Abstract

The study aimed at determining nutritional, antioxidant and blood glucose lowering potentials of improved plantain-based dough meals enriched with defatted soybean and tigernut flour. The constituted dough meals [PSB (plantain 64.46, defatted soybean 35.54%), TNS (tigernut 59.83, defatted soybean 40.17%); PTS (plantain 51.07, tigernut, 11.50, defatted soybean, 37.43%); TNT (100% tigernuts); PLT (100% plantain) and CNT (a commercial flour)] were evaluated for nutritional, antioxidant and blood glucose concentration in streptozotocin-induced diabetics rats. The improved dough meals contained appreciable amount of protein, energy value, and high in antioxidative activity than PLT. Blood glucose reducing potential of improved plantain-based dough meals (60.5–71.9%) in streptozotocin-induced diabetic rats was higher than PLT, but comparable to acarbose (anti-diabetic drug) (69%). The present study established that improved traditional plantain-based dough meals (particularly PTS) was high in essential nutrients, antioxidative activities, and blood glucose reducing potentials. Hence, the dough-meals may be suitable for diabetes management.

Cognitive impairment by non‐insulin‐dependent diabetes mellitus was attenuated by dietary supplements of marble vine (Dioclea reflexa) and plantain (Musa paradisiaca) dough meals in albino rats

“…Hence, substitution of plantain flour with defatted D. reflexa seed flour will, therefore, improve the nutrient quality of plantain‐based products. Similar observation was reported by Oluwajuyitan and Ijarotimi (2019) on dough meals enriched with tigernut and defatted soybean. The moisture content of developed dough meal was not significantly affected by substituted D. reflexa flour.…”

Extruded breakfast meal from malted finger millet (Eleusine coracana) and watermelon (Citrullus lanatus) seed flour: in-vivo nutritional qualities study

“…A similar trend was reported on experimental animals by Mhlomi et al (2019). Biological value evaluates the competence of protein to support growth through nitrogen retention in the body (Oluwajuyitan and Ijarotimi 2019). It is the assessment of the absorbed protein from food that becomes part of the body (Grzeszczuk et al 2020).…”

“…Hematological indices were determined as described by Oluwajuyitan and Ijarotimi (2019). Packed cell volume (PCV) was estimated by centrifuging about 75 Fl of each blood sample in heparinized capillary tubes in a hematocrit microcentrifuge for 5 min.…”

Antioxidant properties, glycemic indices, and carbohydrate hydrolyzing enzymes activities of formulated ginger‐based fruit drinks

“…Thirty six (36) Wistar Albino rats of body weights ranging from 140 to 150 g were used as described by Oluwajuyitan and Ijarotimi (2019). Rats were divided into six groups (6 rats/group), the glycemic indices of the rats were assessed by using an automatic glucose analyzer (“Accu‐chek Active” Diabetes monitoring kit; Roche Diagnostic, Indianapolis, USA) at 0, 30, 60, 90, and 120 min intervals after consumption of the samples (Wolever, Jenkins, Jenkins, & Josse, 1991).…”
