    EFFECT OF STAGES OF DEVELOPMENT AND HOUSEHOLD PROCESSING ON NUTRITIONAL AND SENSORY CHARACTERISTICS OF COWPEA (Vigna unguiculata)
    (Punjab Agricultural University, Ludhiana, 2007) Deol, Jasraj Kaur; Bains, Kiran
    The present study was carried out to assess the effect of stages of development and household processing on nutritional and sensory characteristics of cowpea (Vigna unguiculata). Seed of dual purpose cowpea variety CL-367 were procured from the Forage Section of Department of Plant Breeding, Genetics and Biotechnology, Punjab Agricultural University, Ludhiana. The sowing was done on 11th August, 2006 in Experimental Area of Forage Section. Flowering started in the first week of October, 2006 and tagging of plants was done on 6th October, 2007 to identify the stages of picking of pods. Cowpea pods were picked on 9th, 11th and 13th day after flowering and designated as Stage I, II and III, respectively. The results concluded that the cowpea pods picked on 9th day after flowering had maximum acceptability for vegetable purpose. Though the nutrients such as protein, fat, fibre, ash, carbohydrates, energy, iron and calcium were lower in the pods picked on 9th day when compared to picking on 11th and 13th day after flowering, ascorbic acid and ß-carotene were higher in the pods picked at first stage. The higher content of fibre and antinutrients and the lower moisture values in second and third stage of pod development made them less suitable for consumption as compared to stage first i.e. pod picked on 9th day after flowering.
