Changes also occurred in the concentration of the unavailable carbohydrates. There was no significant difference in moisture content, carbohydrates and protein content between varieties and lines. 8%. By continuing you agree to the use of cookies. Cowpea is one of the most ancient crops known to man. Cowpea is widely distributed in regions of tropical and temperate climates, thus differing morphologically (shape, size, colour of seed coat) and in proximate composition, hence effecting physicochemical characteristics. Feeds such as bajra, cowpea, berseem and the … Carbohydrate content of 50.95% to 53.98% reported for Nhyira, Tona and Adom cowpea varieties were within the ranges recorded in this research [9]. CB 1 content of all feeds was low but similar. Cowpea (Vigna unguiculata (L.) Walp.) Caracterização química de grãos verdes crus e após processamento térmico em cultivares biofortificadas de feijão-caupi. automated Mattson‐type bean cooker. 28 in Cowpea Research, Production and Utilization, Wiley and Sons.. Lignin contents increased slightly while hemicelluloses and celluloses decreased. Chemical characterization of green grain before and after thermal processing in biofortified cowpea cultivars 1. Carbohydrate content reduced after fermentation while anti-nutrient content reduced significantly after fermentation process. Therefore, cowpea seed is valued as a nutritional supplement to cereals and an extender of animal proteins. It was shown that soaking for 3 days reduced fibre content and increased carbohydrates, maybe due to … We selected two cowpea cultivars with contrasting response to salinity, Pitiúba (salt-tolerant) and TVu (salt-sensitive), to investigate whether the salt tolerance could be associated with changes in carbohydrate accumulation and … 62% soluble carbohydrates, and small amounts of other nutrients (Boulter et al. We describe here the enhancement of carbohydrate immunogenicity by an ordered display on the surface of the cowpea mosaic virus (CPMV) capsid. Moisture content determination was carried out using the air oven method at temperature between 103-105°C. However, whilst starch, r… The moisture content, crude fibre and crude fat across all the samples in this study were low, while total carbohydrates were high. The high protein content represents a major advantage in the use of cowpea in nutritional products, for … The protein in cowpea seed is rich in the amino acids, lysine and tryptophan, compared to cereal grains; however, it is deficient in methionine and cystine when compared to animal proteins. 2.6 Ash content The values, on a dry weight basis, ranged from 22.9 to 32.5% for protein, 2.9 to 3.9% for ash, 1.4 to 2.7% for fat, 59.7 to 71.6% for carbohydrate, and 21.1 to 61.9 minutes for 50% cooking time. Cowpea has a number of common names, including … The leaves and flowers can also be consumed. Cowpea is considered nutritious with a protein content of about 23%, fat content of 1.3%, fiber content of 1.8%, carbohydrate content of 67% and water content of 8-9%. Over-view, the cowpea seed protein content measured from the NIR analyzer showed a little higher seed protein content. carbohydrate and protein content of some forage feeds of ruminants for nutritive evaluation, Veterinary World 8(2)197-202. Cowpea line IT97K-1042-3 and TEXAN PINKIYE recorded the highest amount of crude protein. By continuing you agree to the use of cookies. Germination generally showed a decrease in carbohydrate content, an increase in the protein content and a decrease in the fat content of pearl millet and cowpea. As in most legumes, the amino acid profile complements cereal grains. Cowpea (Vigna unguiculata) is a candidate crop for CELSS because of the low-fat, high-complex carbohydrate, moderate protein characteristics of the edible portion. Twenty varieties of cowpea with the following proximate composition: dry matter, 87–94%; crude protein, 24–33% ether extract, 1–2%; crude fibre, 2–5% and ash, 2–5% were analysed for sugar contents, starch, cell wall carbohydrates and lignin. Calculation % Moisture content = Weight Loss WeightofSample × 100 2.6 Ash content Cowpea is commonly cultivated as a nutritious and highly palatable food source in the southern United States, Middle East, Africa, Asia, and throughout the tropics and subtropics. A decrease in the concentration of total carbohydrates was observed during 144 hours' germination of three cowpea varieties. 1 From Bressani R. Chap. Biodiversitas 21: 85-91. Carbohydrate content reduced after fermentation while anti-nutrient content reduced significantly after fermentation process. The seed is reported to contain 24% crude protein, 53% carbohydrates, and 2% fat (FAO, 2012). 1984). generally showed a decrease in carbohydrate content, an increase in the protein content and a decrease in the fat content of pearl millet and cowpea. However, whilst starch, raffinose, stachyose and verbascose levels decreased, the reducing sugars, including glucose and fructose, increased. Black-eyed peas have been associated with a number of powerful health benefits. Results: Among green fodders, cowpea and berseem had higher CA content while except hedge lucerne all range herbages had lower CA values. The above-mentioned changes, occurring during germination, appear to have a favourable effect on the nutritional value of cowpea varieties.

ScienceDirect ® is a registered trademark of Elsevier B.V. Changes in carbohydrate contents of germinating cowpea seeds. Calculation. CB1 content of all feeds was low but similar. Thus, most of its nutritional value is provided by proteins and carbohydrates. Support weight loss. Overall, a reduction in the ANC content (phytic acid, polyphenols and raffinose family oligosaccharides) was shown after fermentation and … Water stress reduced net photosynthesis (A net), stomatal conductance (g sw), and transpiration, increased intercellular CO 2 concentration (C i), but had no effect on leaf water content (LWC) of the trifoliates in all cowpea cultivars regardless of the type or level of drought tolerance. Forage: A decrease in the concentration of total carbohydrates was observed during 144 hours' germination of three cowpea varieties. Its origin and subsequent domestication is associated with pearl millet and sorghum in Africa. The seeds ("black-eyed peas") are considered the edible form of the plant in the United States, but the leaves serve as a major staple in the diet throughout Africa and Asia (Bittenbender et al. There was significant increase in protein content of sorghum supplemented with cowpea, and a drastic ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Carbohydrate composition of different varieties of cowpea (. There have been attempts to reduce fibrousness of cowpea hulls by different physico-chemical treatments such as soaking plus boiling or soaking for 3 days. Abstract. Under salinity stress, plants commonly accumulate carbohydrates for osmotic adjustment to balance the excess accumulated ions and to protect biomolecules. 2.5 Moisture content Moisture content determination was carried out using the air oven method at temperature between 103-105°C. Insect infestation decreased the carbohydrate content of the stored grains, causing a relative increase in the proportionofprotein and fibre inthe remaining grain,and moisturecontent alsoincreased.Sitophiluszeamais preferentially fed in the floury endosperm of maize, resulting in more carbohydrate loss relative to protein loss.

This indicates how the nutrient content of insect-infested stored grain depends upon the grain type, the infesting insect, and the infestation level. content for cowpea seeds with the five types of seed coat except black. The carbohydrate content of the flours for cowpea and wheat flours was comparable to 57.17% for cowpea, 74.22% for wheat; reported by [4]. Copyright © 1980 Published by Elsevier Ltd. https://doi.org/10.1016/0308-8146(80)90031-X. Nutrients are distributed more homogenously within cowpea than in maize grains, but Callosobruchus maculatus infestation increased the relative protein, fat, iron and zinc to carbohydrate ratios. Increase in cowpea soaking time resulted in protein increase of GC. Starch was the major carbohydrate and about 50% of it was hydrolysed after 144 hours' germination. A series of regression models with different seed coat color have been built to adjust to protein content of color-How to cite this paper: Weng, Y.J., Shi, A., Short Communication: Characterization and nutrient analysis of seed of local cowpea (Vigna unguiculata) varieties from Southwest Maluku, Indonesia. However, some cowpea varieties are difficult to cook, resulting in high energy requirements and greater loss of nutrients. Genetic variability was observed for all traits. Markets and Economics With alternative crops such as dried black-eyed or All feeds except cowpea, berseem, and hedge lucerne contained higher CB2 values. Cowpea is another underutilized and under researched crop in South Africa and is grown mainly by subsistence farmers for its leaves and seeds for human consumption. 1975). Oat among green fodders and hybrid napier among range herbages had lower CC fraction. Karuwal RL, Suharsono, Tjahjoleksono A, Hanif N. 2021. The carbohydrate content is quite high, (44.29 ± 1.50%) while it has low crude fibre content (4.70 ± 0.15%). Carbohydrates: 60.03 g: 46%: Protein: 23.52 g: 42%: Total Fat: 1.26 g: 6%: Cholesterol: 0 mg: 0%: Dietary Fiber: 10.6 g: 28%: Vitamins; Folates: 633 μg: 158%: Niacin: 2.075 mg: 13%: Pantothenic acid: 1.496 mg: 30%: Pyridoxine: 0.357 mg: 27%: … The protein content of EC and FC blends oscillated across soaking time. The highest protein value (29.34%) was recorded for EC (6 h of steeping), while the lowest protein content (20.83%) was in GC (3 h of steeping). It is now a broadly adapted and highly variable crop, cultivated around the world primarily for seed, but also as a vegetable (for leafy greens, green pods, fresh shelled green peas, and shelled dried peas), a cover crop and for fodder. Due to their Moisture, ash, crude fibre, crude protein, crude carbohydrate, crude fats contents of the cowpea cultivars were determined according to methods described by A.O.A.C [6]. Copyright © 2021 Elsevier B.V. or its licensors or contributors. nutrient contents. However, the low immunogenecity of carbohydrates presents a formidable challenge. Fermentation of cowpea generally showed a decrease in carbohydrate content, no significant changes in the protein content and contradictory results in the fat content. This might be attributed to the quantity of steeped cowpea flour in the blends. There was significant increase in protein content of sorghum supplemented with cowpea, and a drastic reduction in the anti-nutrient content of all the fermented sample blends. 2.5 Moisture content.
