Evaluation of nutritional quality of grain legume Psophocarpus tetragonolobus using the red flour beetle Tribolium castaneum

Mohd Ismail Mohd Noor, . and Rohaya S., . and Jalani bin Sukami, . (1986) Evaluation of nutritional quality of grain legume Psophocarpus tetragonolobus using the red flour beetle Tribolium castaneum. [Proceedings Paper]

Protein quality of 12 cultivars of winged bean with 3 different testa colours were determined using the red flour beetle Tribolium castaneum. Samples of raw cooked and roasted winged bean were tested using two criteria: body weight gain in growing larvae in a 4 day period from the 12th day to the 16th day and the developmental progress of the organism on test diets. They were assessed by counting at 2 day intervals from day 24 until 30 day of age. Results obtained on larval weight gains and the different metamorphic stages observed indicated that there was no significant difference among the 12 cultivars and 3 different testa colours under study. These results also confirmed protein quality of raw winged beans significantly decreased while cooking and roasting improved the protein quality of the diet however the differences between the two heat treatments were not statistically significant. Tribolium assay is inexpensive reliable and may prove to be of great significance in plant breeding programmes where comparisons of nutritional quality of many lines could be carried out rapidly and utilizing only a few grams of samples

Abstract

Protein quality of 12 cultivars of winged bean with 3 different testa colours were determined using the red flour beetle Tribolium castaneum. Samples of raw cooked and roasted winged bean were tested using two criteria: body weight gain in growing larvae in a 4 day period from the 12th day to the 16th day and the developmental progress of the organism on test diets. They were assessed by counting at 2 day intervals from day 24 until 30 day of age. Results obtained on larval weight gains and the different metamorphic stages observed indicated that there was no significant difference among the 12 cultivars and 3 different testa colours under study. These results also confirmed protein quality of raw winged beans significantly decreased while cooking and roasting improved the protein quality of the diet however the differences between the two heat treatments were not statistically significant. Tribolium assay is inexpensive reliable and may prove to be of great significance in plant breeding programmes where comparisons of nutritional quality of many lines could be carried out rapidly and utilizing only a few grams of samples
