“…The low feed intake at these high levels could have contributed to the higher mortality. Methionine was included in some of the diets because castor bean cake has been found to be low in methionine (Polit and Sgabieri, 1976;Satar et al, 1979). Its inclusion significantly reduced mortality at all levels despite the fact that it slightly increased daily feed intake in most of the diets.…”

Castor bean cake was prepared from castor bean seeds roasted at 140 degrees C for 20 min and found free from ricin by chemical analysis. The cake was incorporated into diets at 0, 10, 15, 20 and 25% levels and fed to ducks for 6 weeks. Diarrhoea, emaciation and death were observed mainly at 20 and 25% levels. Congestion of the internal organs and haemorrhagic enteritis were found at necropsy of dead birds. There were necrosis and depletion of the parenchymal cells of the liver and lymphoid organs. Most of the histopathological changes in birds killed after 5 weeks of feeding were more severe at 10 and 15% levels. These lesions included degeneration of the renal epithelial cells, hepatocytes, bile duct proliferation and lymphocytic depletion in the lymphoid organs. The average daily feed intake and weight gain were reduced while the mortality was increased at the higher levels of castor bean feeding. The toxicity of the meal could be due to either a heat stable or growth inhibiting factor or due to minute residues of ricin.

“…Therefore, some chemical qualitative and quantitative analysis of allergen are necessary for the evaluation of this extraction method. Up to today, HPLC [3] , polyacrylamide gel electrophoresis [4] and DSC melting point determination apparatus assay methods [5] have been used for this. On the basis of this, an efficient extraction method of allergen from CBM was established.…”

The influence of ultrasound-microwave during extraction of Ricinus communis(L）allergen from castor bean meal (CBM) was investigated. The method was successfully applied for the ultrasound- microwave assisted extraction (UME) of allergen from CBM. The corresponding extraction parameters including the extraction temperature, ultrasonic-microwave power and extraction time were investigated. The CBM was crushed, sifted, ground and suspended for 4 h in 25% ethanol water (1:4) at room temperature followed by ultrasound-microwave. The yield, polysaccharose and protein contents were determined after each processing step. The purity of extracted allergen was tested through HPLC and the Sephadex G-100 and Tricine-SDS-PAGE detection with unique electrophoresis strip documented that allergen was purifed.. The paper describes the conditions of the temperature,time,and microwave-power for the method reliability with UME and suitablilty for the effective extraction of allergen from CBM.

Moringa oleifera Lam is a multipurpose tree cultivated to use as a vegetable, for spice, for cooking and cosmetic oil and as a medicinal plant. Owing to the use of its seeds as food and as a clarifying agent of turbid water some nutritional and antinutritional characteristics were studied. The mature seeds contained 332.5 g crude protein, 412.0 g crude fat, 211.2 g carbohydrate and 44.3 g ash per kg dry matter. The essential amino acid profile compared with the FAO/WHO/UNU scoring pattern requirements for different age groups showed deficiency of lysine, threonine and valine. The content of methionine + cysteine (43.6 g kg−1 protein), however, was exceptionally higher and close to that of human milk, chicken egg and cow's milk. The seed extract agglutinated rabbit erythrocytes but did not show trypsin inhibitor and urease activities. Feeding rats with a diet containing the seed meal showed loss of appetite, impaired growth, lower NPU and enlargement of stomach, small intestine, caecum + colon, liver, pancreas, kidneys, heart and lungs and atrophy of thymus and spleen in comparison with rats fed on an egg‐white diet. The results indicated that consumption of M oleifera raw mature seeds should be viewed with some caution until suitable processing methods are developed to abolish the yet unknown adverse factors. © 1999 Society of Chemical Industry
