EnvIronmental variables affect the hard-to-cook phenomenon of cowpea (Vigna unguiculata) seed
Plant Foods for Human Nutrition, 1999Co-Authors: S.s. ArogbaAbstract:Changes in moisture content and cooking rate of cowpea (Vigna unguiculata) seeds which were sun-dried for 5 hours on cement, wood, or Corrugated Iron sheet surfaces and packaged for 6 months in jute or polythene bags were studied. Relationships and effects of interacting variables studied were examined using the contrast analysis technique. From day zero to about 2 months of storage, the sun-dried samples had significantly (p

The effects of post‐harvest handling on physical, chemical and functional properties of cowpea (Vigna unguiculata) seed
Journal of the Science of Food and Agriculture, 1999Co-Authors: S.s. Arogba, F.m. UgwuAbstract:Damage by insects and mould, proximate composition, cooking rate and functional properties of sun-dried and stored cowpea (Vigna unguiculata) seeds were evaluated. Cowpea samples spread between black polythene films were placed on cement (CS), Wooden (WS) and Corrugated Iron sheet (CIS) surfaces, respectively, and sun-dried for 5 h. Storage lasted 6 months in jute and polythene bags. Results show that sun-drying and storage in polythene bags significantly (p< 0.05) lowered the extent of insect and mould damage, moisture-loss at drying, emulsion activity and stability, foaming capacity and foam stability. Treated cowpea seeds could be stored safely for about 5 months. In contrast, storage in jute bags significantly (p< 0.05) lowered only foam stability. Moisture loss during sun-drying principally lengthened cooking time as storage duration progressed. Therefore, assessment of moisture content before and during storage is a preferred quality index of cowpea seeds stored in polythene bags. # 1999 Society of Chemical Industry 30% in a 6 month storage has been reported. 2 The choice of appropriate drying techniques for food crops in the tropics is based on cost. Sun-drying is attractive to the small-scale farmers who are respon- sible for the production and preservation of the majority of the food crops in developing countries. Spreading of soyabean seeds on cement floors covered with black polythene film in order to enhance the retention of solar energy during sun-drying is a recent practice. 3 The effect of heat treatment on functional properties of raw and processed brown bean (Cana- valia rosea DC) flour has been reported. 4 The quality of cowpeas dried on different surfaces, such as cement, wood and Corrugated Iron sheet, has not been investigated. The objectives of the present study were, therefore, to evaluate the effects of sun- drying using the surfaces mentioned on the rate of

The effects of sun-drying surfaces and packaging materials on the storability of cowpea ( Vigna unguiculata) seed
Plant Foods for Human Nutrition, 1998Co-Authors: S.s. Arogba, F.m. UgwuAbstract:The effects of sun-drying cowpea seeds for three hours on cement (CS), wood (WS), and Corrugated Iron sheet (CIS) surfaces and packaging separately in polyethene and jute bags were studied. Moisture-gain, and resistance to insect and mold damage were monitored monthly for six months, while proximate analyses on day zero and at the 6th month were conducted. Results showed that the three-hour sun-drying of cowpea seeds on reflective surfaces (CIS and CS) enhanced the rate of moisture-reabsorption during storage and consequently, the degree of mold and insect damage irrespective of the packaging material employed. Crude fat, fiber and ash contents, unlike protein and moisture contents, remained virtually constant ( p ≤ 0.05). In this study, the wood surface and polyethene bag were the most preferred treatments to store sun-dried cowpea seeds for about 5.7 months.

Effect of different sun-drying surfaces on the functional properties, cooking and insect infestation of cowpea seeds
Bioresource Technology, 1999Co-Authors: F.m. Ugwu, F.c. EkwuAbstract:Abstract Three traditional sun-drying surfaces, a wooden surface (WS), a Corrugated Iron sheet surface (CIS) and a cement surface (CS) were used to disinfect cowpea (Vigna ungiculata) seeds for 5 h in the sun. The values of foam capacity, fats and water absorption capacities, emulsion capacity, mould and insect infestations were lower in the dried samples than in the control. The wooden surface (WS) was the most effective sun-drying surface in terms of insect disinfestation, and functional-property retention. The water and fat absorption capacities and emulsifying activities were generally improved with storage. The cooking time was highly correlated (r = 0·987–0·993) with storage period for all the surfaces tested.
