Comparative study on proximate, functional, mineral, and antinutrient composition of fermented, defatted, and protein isolate of Parkia biglobosa seed

Abstract

The use of plant‐derived foods in the prevention, treatment, and management of metabolic diseases especially diabetes has gained prominence; this has been associated with their physicochemical properties. This study was conducted to compare the proximate, functional, mineral, and antinutrient composition of the fermented seeds, the defatted seeds, and the protein isolate from Parkia biglobosa seeds. The results showed that the fermented, defatted, and protein isolate varied in composition within the parameters studied. The proximate analysis revealed that the protein isolate had the highest ash (6.0%) and protein (59.4%) as well as the lowest fat (5.7%) and moisture (5.1%) content when compared to the fermented and defatted samples. In like manner, the functional properties of the protein isolate were relatively better than those of the fermented and defatted samples, with oil absorption capacity of 4.2% and emulsion capacity of 82%. The magnesium and zinc content of the protein isolate were significantly higher when compared with the fermented and defatted samples, while a negligible amount of antinutrient was present in all the samples, with the protein isolate having the lowest quantity. The overall data suggest that the protein isolate had better proximate, mineral, functional, and antinutrient properties when compared to the fermented and defatted samples. Therefore, the synergistic effect of all these components present in the protein isolate from P. biglobosa seed in association with its low carbohydrate and high protein/ash contents could play a vital role in the management of diabetes and its associated complications.

Manufacturing Technique and Nutritive Value of Soumbara (<i>Parkia biglobosa</i> Seeds) and Dark Seed of Korhogo (Côte d’Ivoire)

“…Thus, a daily consumption of soumbara would be beneficial for the consumer The fermented seeds of P. biglobosa studied, have a water content of 13.3%. This value is higher than that obtained by [30]. These authors found values between 5.1 and 10.2% on fermented seeds of P. biglobosa in Nigeria.…”

Genus Parkia: Phytochemical, Medicinal Uses, and Pharmacological Properties

“…Each pod contains up to 25–30 seeds. Many species from Parkia have been reported to be rich in carbohydrate [ 5 , 6 , 7 ], protein [ 8 , 9 , 10 ] and minerals [ 11 , 12 , 13 , 14 ].…”

Inhibitory Effects of Solvent-Partitioned Fractions of Two Nigerian Herbs (Spondias mombin Linn. and Mangifera indica L.) on α-Amylase and α-Glucosidase

“…Evidence from traditional prescription and scientific investigation reveals optimum therapeutic efficacy of medicinal plants with a good margin of safety. Since medicinal plants form a major part of human food, it is worthwhile to evaluate their inhibitory activity against hyperglycemia [ 2 , 3 ].…”
