Effect of long-term storage of processed Nigeria-grown edible leafy green vegetables on vitamin C content

The purposes were to determine the most appropriate blanching time for some common fresh, edible green vegetable leaves and to assess the ascorbic acid level of the procesed leaves kept under different storage conditions for a specific period.

Nutritional Effects Of Heat Processing Of Some Nigerian Leafy Vegetables

Six edible leafy vegetables in Nigeria were subjected to the heat treatment of the local methods of cooking and the nutritional consequencies were assessed.Generally, the heating lowering the nutri...

Distribution of an enzyme system producing cis-3-hexenal and n-hexanal from linolenic and linoleic acids in some plants

The activity of the enzyme system (E 2-I) producing C 6-aldehydes from C 18-unsaturated fatty acids was investigated using about 40 plants. Green leaves of dicotyledonous plants belonging to the Sphenopsida, Pteropsida Theaceae and Leguminosae showed a high enzyme (E 2-I) activity but edible leafy vegetables and fuits and monocotyledonous plants showed a low activity. Seasonal changes in the enzyme (E 2-I) activities were observed. The concentrations of cis-3-hexenol (leaf alcohol) and trans-2-hexenal (leaf aldehyde) and the enzyme (E 2-I) activities showed a correlation; high concentrations were observed in the summer but they were low in the winter.

Effects of Age and Season on Yield of Crude and Extractable Proteins from Some Edible Plants

The crude protein contents of four Nigerian edible leafy vegetables were high, with values ranging from ao to 30% on a dry weight basis and maximum yields of crude protein ranging from 428 to 602 kg/ha. The percentages of leaf protein extracted ranged from 41 to 70%, whilst the highest yields of extractable edible protein varied from 199 to 332 kg/ha. The crude protein levels, as well as yields of extractable proteins, were slightly affected by the season of growth, but greatly by the age and species of plants.
